Magnesium

Magnesium is an essential mineral involved in hundreds of enzyme reactions, including those that regulate nerve signaling, muscle contraction, blood sugar, blood pressure, and energy production. Although magnesium supplements are often promoted for sleep, stress, and muscle cramps, their benefits depend on a person's magnesium status, the condition being treated, and the amount taken.

At a Glance

Daily requirement: Most adults need 310–420 mg of magnesium per day from food and supplements combined, depending on age and sex.

Supplement safety limit: For adults, the usual upper limit is 350 mg per day from supplements and medications unless a clinician recommends otherwise.

Popular forms: Glycinate is often chosen for tolerability, citrate for constipation, and oxide is used in some migraine-prevention protocols.

Important: The milligrams of elemental magnesium—not the weight of the entire compound—determine the dose.

Magnesium Dosage Guide for Adults

This is the dosing guide. The first table shows how much magnesium adults need each day. These are total daily intake targets, not instructions to take that amount in pills.

Group Recommended Daily Intake (Food + Supplements)
Men, 19–30 400 mg
Men, 31+ 420 mg
Women, 19–30 310 mg
Women, 31+ 320 mg
Pregnancy, adults 350–360 mg (varies with age)

How much magnesium supplement should you take? There is no single supplement dose appropriate for everyone. A supplement containing 100–200 mg of elemental magnesium per day is a commonly used amount to discuss with a clinician when dietary intake is inadequate. It is not a universal prescription or a treatment dose for a particular symptom. Count magnesium from multivitamins, antacids, and laxatives as well.

Important distinction: The adult upper limit of 350 mg/day applies to magnesium from supplements and medications, not magnesium naturally present in food. Higher amounts are sometimes used medically, including for migraine prevention, but should be supervised.

How to Read a Magnesium Supplement Label

If a label says “Magnesium (as magnesium glycinate) 120 mg”, the 120 mg ordinarily refers to elemental magnesium. If a product instead lists only the weight of “magnesium glycinate,” do not assume that the entire amount is elemental magnesium. Check the Supplement Facts panel or ask the manufacturer.

Dosage by Purpose: What Research and Clinical Practice Suggest

Purpose Amount / Approach What to Know
Filling a dietary gap Individualized; 100–200 mg/day elemental magnesium is a common supplement amount Assess diet first; keep total supplemental intake within the usual limit unless advised otherwise.
Migraine prevention Some clinical protocols use 400–600 mg/day elemental magnesium Exceeds the usual supplemental upper limit; use with medical guidance. Benefit is better supported for migraine than for most other uses.
Occasional constipation Use the specific product's labeled directions Citrate and hydroxide can act as osmotic laxatives; laxative doses are not interchangeable with daily nutrition doses.
Sleep, stress, or cramps No established condition-specific dose Evidence is mixed or limited; correcting a low intake may be more useful than taking high doses.

Which Form of Magnesium Is Best?

Magnesium forms differ in solubility, tolerability, and how they are used. Claims that one form selectively reaches the heart, nerves, or brain are often stronger than the available human evidence.

Form Common Reason for Choosing It Research Snapshot / What to Know
Glycinate / Bisglycinate General supplementation; often selected for evening use Often well tolerated, but evidence that it uniquely improves sleep or anxiety is limited.
Citrate Supplementation; constipation Relatively well absorbed; may loosen stools.
Malate General supplementation; marketed for fatigue Evidence for specific energy or chronic-pain benefits is insufficient.
L-Threonate Marketed for memory and cognition Early human research is interesting but does not establish superior cognitive benefit or treatment of brain fog.
Taurate Marketed for cardiovascular support Insufficient evidence that this form has unique heart or blood-pressure benefits.
Chloride Oral supplements; topical sprays Oral magnesium chloride is absorbable; meaningful absorption through intact skin has not been established.
Sulfate (Epsom Salt) Baths and soaks Warm baths may feel relaxing; reliable magnesium delivery through skin is unproven. Do not drink bath products.
Oxide Migraine protocols; some antacid/laxative products Less readily absorbed than some soluble forms, but used in migraine studies. May cause diarrhea; not a “detox” treatment.

What to know: Using two different magnesium forms does not double the safe daily amount. Add up their elemental magnesium content.

Could You Be Low in Magnesium?

Low magnesium intake or deficiency may occur with poor dietary intake, gastrointestinal disorders, certain medications, or increased urinary losses. Early symptoms can include loss of appetite, nausea, fatigue, and weakness. More serious deficiency can cause muscle spasms, numbness, abnormal heart rhythms, or seizures.

Signs Worth Discussing With a Clinician

Persistent muscle twitching or cramps, unexplained weakness, or ongoing fatigue can justify reviewing magnesium intake and medical causes. Tinnitus, chocolate cravings, brain fog, constipation, and feeling “wired but tired” are not reliable diagnostic tests for magnesium deficiency. There is no validated symptom-count quiz that confirms deficiency. A clinician may use blood tests alongside symptoms, medication history, and other findings; serum magnesium alone does not capture all body magnesium stores.

Seek prompt medical attention for palpitations accompanied by chest pain, fainting, breathlessness, or severe dizziness rather than assuming magnesium is the answer.

Magnesium Health Benefits: What the Research Says

Sleep and Stress

Research Snapshot: Small trials and reviews suggest possible improvements in certain sleep or anxiety measures, but studies are inconsistent and often small. Magnesium is not an established treatment for chronic insomnia or anxiety disorders.

What to Know: Adequate intake supports normal nervous-system function; claims that supplements directly “reset” the vagus nerve or reliably calm an overactive nervous system are not established.

Migraines and Headaches

Research Snapshot: Magnesium has evidence for migraine prevention, especially in people with migraine aura or menstrual migraine. Some specialist protocols use doses above the usual supplemental safety limit.

What to Know: Discuss migraine-specific dosing with a clinician rather than increasing supplements independently.

Muscles, Cramps, and Exercise

Research Snapshot: Magnesium is necessary for normal muscle contraction and relaxation. Replacing a deficiency is important, but supplements have not consistently relieved ordinary nighttime leg cramps in people without deficiency.

What to Know: Recurrent cramps can have several causes, including medications, overuse, and circulation or nerve problems.

Blood Pressure, Blood Sugar, and Bone Health

Research Snapshot: Magnesium contributes to normal cardiovascular, glucose, and bone physiology. Supplementation may modestly reduce blood pressure in some populations, but effects vary. Associations between magnesium intake and metabolic health do not establish magnesium as a GLP-1 substitute or diabetes treatment.

What to Know: Adequate dietary intake is a sensible foundation, not a replacement for prescribed treatment.

Tinnitus and Cognitive Function

Research Snapshot: Evidence that oral magnesium reduces tinnitus is preliminary and insufficient for routine treatment recommendations. Magnesium L-threonate is being investigated for cognitive outcomes, but strong evidence of a special brain-targeting advantage in people is lacking.

What to Know: New, one-sided, pulsating, or hearing-loss-associated tinnitus deserves medical evaluation.

Earth Clinic Readers' Experiences With Magnesium

Earth Clinic readers have shared a wide range of experiences with magnesium, from improved sleep and fewer migraines to relief from muscle discomfort and unexpected reactions to certain forms. Some of the most-loved posts offer particularly useful insights into how people respond differently to magnesium supplements.

The following highlights are drawn from popular community posts. These personal experiences are not clinical proof of effectiveness, but they can help readers understand what others have tried and what questions to consider before choosing a magnesium supplement.

Comparing Magnesium Citrate, Oxide, and Topical Magnesium

Mama to Many (Tennessee, USA) — 2016

In one of Earth Clinic's most-loved magnesium posts, Mama to Many shared her family's experiences with several forms of magnesium. She discussed magnesium citrate and oxide as well as topical magnesium preparations, explaining that different forms seemed useful for different purposes.

Her experience illustrates an important point: the best magnesium preparation may depend on individual tolerance and the reason for taking it. A form that works well for one person may cause digestive discomfort or provide little noticeable benefit for another.

What to Know: Magnesium citrate is relatively well absorbed and can loosen stools. Magnesium oxide is less readily absorbed but has established uses in certain products and migraine protocols. Although topical magnesium is popular, reliable evidence that it significantly increases magnesium levels through intact skin is lacking.

Magnesium and Arthritis Discomfort

Moira (Cork, Ireland) — 2009

Moira described an improvement in arthritis-related pain and swelling after using magnesium. Her experience attracted considerable interest from other readers seeking nutritional approaches to joint discomfort.

Research Snapshot: Magnesium plays a role in normal muscle and nerve function, and low magnesium intake has been associated with inflammatory markers in some studies. However, clinical evidence does not establish magnesium supplements as a treatment for arthritis or joint swelling.

An Unexpected Improvement in Bladder Control

Arcticlily (Anchorage, Alaska, USA) — 2012

Arcticlily reported a noticeable improvement in urinary incontinence while using magnesium. Although bladder control is not one of the most commonly discussed reasons for taking magnesium, her experience resonated with many Earth Clinic readers.

What to Know: Magnesium influences muscle and nerve activity, but evidence supporting oral magnesium for urinary incontinence is limited. Persistent or new bladder symptoms deserve evaluation because they can have several underlying causes.

Magnesium Glycinate for Mood and Anxiety

Doris (Murfreesboro, Tennessee, USA) — 2007

Doris shared a positive experience using magnesium glycinate for depression and anxiety symptoms. Her account is among the more popular discussions of magnesium's possible effects on mood.

Research Snapshot: Magnesium is involved in neurotransmitter signaling, and some small studies suggest supplementation may improve certain mood symptoms. However, findings are inconsistent, and magnesium is not a substitute for established treatment of depression or anxiety.

Safety Note: The amounts described in some older reader reports may exceed current supplemental intake recommendations. Readers should not copy high-dose regimens without medical guidance.

Magnesium for Migraines With Aura

Janet (Louisville, Colorado, USA) — 2009

Janet described improvements in frequent migraines with aura after using ionic magnesium. Her detailed experience is especially relevant because migraine prevention is one of the better-researched applications of magnesium.

Research Snapshot: Magnesium supplementation may help reduce migraine frequency in some people. Migraine-prevention protocols sometimes use amounts above the standard upper limit for supplemental magnesium and should be supervised by a healthcare professional.

Better Sleep and Reduced Anxiety

Carrie (Livonia, Michigan, USA) — 2015

Carrie reported improvements in sleep, anxiety, and several other symptoms after beginning a chelated magnesium supplement. Her experience reflects one of the most frequent reasons readers explore magnesium: the hope of feeling calmer and sleeping more comfortably.

What to Know: Correcting inadequate magnesium intake supports normal nervous-system function. However, evidence that supplementation consistently improves sleep in people without magnesium deficiency remains limited.

Finding a More Comfortable Topical Preparation

Kate (Oregon City, Oregon, USA)

Kate described difficulty tolerating oral magnesium and irritation from a homemade Epsom salt spray. She later reported a more comfortable experience using a homemade magnesium cream.

Her account is a useful reminder that even products marketed as gentle or natural can cause unwanted reactions, and that individual tolerability can vary considerably.

What to Know: Topical preparations may irritate sensitive skin. Although creams and sprays are widely used, there is insufficient reliable evidence that they correct magnesium deficiency through skin absorption.

When Magnesium Malate Made Sleep Worse

Kathy (New Brunswick, Canada)

Kathy reported that approximately 200 mg of magnesium malate taken at night appeared to worsen her insomnia, even though magnesium had previously been helpful for her.

This experience provides an important counterpoint to the many positive sleep reports. Not everyone experiences magnesium as calming, and the timing or formulation may affect individual tolerance.

What to Know: There is insufficient evidence that magnesium malate is inherently stimulating. Changes in sleep may reflect individual responses, other ingredients, or unrelated factors. A supplement that consistently worsens symptoms should be reassessed.

What These Experiences Tell Us

Across these popular reports, three themes stand out:

  • Different forms may produce different experiences. Some readers prefer glycinate or chelated magnesium, while others discuss citrate, oxide, ionic magnesium, or topical preparations.
  • Benefits are highly individual. Reports range from improvements in migraines, sleep, and mood to less commonly discussed effects on joints or bladder control.
  • Side effects matter. Digestive intolerance, skin irritation, and unexpected sleep changes are important parts of the discussion, not simply exceptions to positive experiences.

Reader feedback can help identify questions for further research, but it cannot establish cause and effect. The form, elemental dose, other medications, and underlying health conditions should all be considered when evaluating an experience.

Have You Tried Magnesium?

Earth Clinic welcomes your experience with magnesium, whether it helped, made no difference, or caused an unwanted reaction.

If possible, include the form of magnesium, elemental dose, time of day, length of use, and results. These details make your feedback especially helpful to others.

Explore additional experiences in the magnesium reader feedback section below, or browse the most-loved magnesium posts.

Magnesium-Rich Foods

Food is a useful starting point because it provides magnesium alongside fiber and other nutrients. Options include pumpkin seeds, almonds, cashews, beans, lentils, tofu, spinach, whole grains, and dark chocolate. A varied diet can provide substantial magnesium without the gastrointestinal side effects of large supplemental doses.

Safety, Side Effects, and Medication Interactions

Magnesium supplements may cause diarrhea, nausea, and abdominal cramps. High doses can be dangerous, particularly with impaired kidney function. People with kidney disease should not self-treat with magnesium supplements or magnesium-containing laxatives.

Magnesium can reduce absorption of certain antibiotics and osteoporosis medicines if taken too close together. Diuretics and long-term proton pump inhibitor use can also affect magnesium status. Ask a pharmacist about exact spacing for your medications. Pregnancy, heart rhythm conditions, and medically prescribed higher-dose magnesium warrant individualized advice.

Important: “More” is not necessarily better, and supplements marketed for sleep or muscle relief can still contribute to the same total supplemental magnesium intake.

Research and References

Takeaway

Magnesium is essential for nerve, muscle, bone, and metabolic health. For most people, the best first step is to evaluate dietary intake and choose a supplement only when it fills a genuine need. Use the Magnesium Dosage Guide to understand daily requirements and supplement limits, then consult the Magnesium Forms Comparison to find a preparation that fits your goals and tolerance. If you have tried magnesium, Earth Clinic welcomes your experience—including the form, elemental dose, and whether it helped.

Anal Fissure


Posted by Audrey (Delray Beach, Florida, USA) on 03/21/2009
★★★★☆

BETTER BUT WITH SIDE EFFECTS

Magnesium citrate supplement: I developed an internal fissure from having soft, but very wide stools. Doctor said would need surgery if don't make stools literally fall out. So tried magensium citrate supplement (won't give name). It worked, fissure healed. But I have found that magensium citrate can be very irritating. I developed burning in throat and burning in stomach and tremendous bloating and constant gas. I should have stopped immediately (the burning started on day1) but was so anxious to heal fissure that I took it for 3 weeks (tiny dose). Now off of it for about 8 days and still have burning and off and on colon discomfort. A friend was also trying it - she has had no burning but finally had to stop due to continuous colon rumbling and discomfort - just can't live that way all the time. And sadly it worked for both of us. Just thought people should know this. Sometimes, just because it is "natural" doesn't always mean it is good for you.

Take Magnesium Taurate. See an Auricular Medicine Doctor for reassurance. Dr. Carolyn Dean recommends mag. Taurate. I take buffered mag. Taurate. Or, apply Magnesium Oil. This is an excellent alternative bc it bypasses your digestive system and goes to work as soon as it is absorbed through the skin. Tip: make sure skin is slightly moist (warm water) and it will go on smoothly and readily. Good luck. LB

You should try taking ReMag magnesium. It's a liquid (doesn't taste good) formulated to go right into your cells so you can take as much as you need to get your magnesium levels up without getting diarrhea. I actually took this for Afib & stopped, but I'm now gonna restart it again. I didn't realize it could heal a fistula — which I have when they ripped my bladder & uterus apart during a C-section.

I have taken magnesium taurate for years and it completely eliminates my irregular heartbeat. I also take magnesium Glycinate for my depression and insomnia. I always try to stay at 200mgs or below using supplements. There are so many different kinds of magnesium that you need to find the one you need for your problems. These are just my experiences using magnesium.


Arrhythmia

I was getting atrial fibrillation attacks for 7 or 8 years, mostly in the mornings in winter. I could only sit quietly until it went away, dreadful feeling.

Taking a quarter tsp magnesium chloride everyday cured me very quickly, I don't need to take it any more now that I'm retired and not as active and my reserves are presumably back to normal.

I believe I developed atrial fibrillation because of heavy sweating due to physical outdoor work depleting my reserves of magnesium. All the doctors could prescribe were beta blockers which I soon stopped taking, but it was years before I discovered three people on one website, who had cured themselves of this awful affliction. Very much hope this helps others.

Taurine regulates heartbeat, so if this occurs again for you or anyone else, consider reading up on taurine. Cystine pushes out taurine, so make sure you aren't testing with high cystine levels.

Legna,

You ask where to get magnesium chloride...

You should be able to get it at any health food store or on line.

Epsom salts is magnesium sulfate. I've used that for A Fib too. I take orally magnesium citrate that an alternative MD got me on. As long as you are getting the magnesium in you I'm not sure I can determine that it really matters the form you receive it. I've asked that very question a number of times on EC but haven't gotten a response ... that is that one form is preferred. I'd love to hear from someone to lay all the different forms of magnesium out to explain what and why one is better than another.

For A Fib I also make sure I'm getting at least 400IUs of natural (NOT synthetic) vitamin E. I take the amino acid arginine also for the heart and general cardio support.

Apollo won nine gold medals in the winter olympics. He takes colostrum. Ron Teagarden takes fermented adaptogens. They don't take isolates. There are many websites that explain why isolates are not effective, like mini minerals, and fulvic acid is necessary for mineral absorption to name a couple. Some say the molecule is too big and some say because they are inorganic. Gardeners don't put isolates on their plants. They put compost. Nutrients are like a world class symphony. All the musical instruments have to be there in the proper ratio, finely tuned, and with great musicians.

Hey Mike 62,

Thanks for your response to my response to Legna.

Legna had asked where to get Mag Chloride.

I told her and elaborated that there are numerous magnesiums, so the magnesium chloride would not be the only magnesium that would help with A Fib.

Your response was to criticize isolates as opposed to whole foods ... if I understood you correctly. I re-read her question and my response and the issue was very narrow. Your response was not the issue but nonetheless I'll speak to your viewpoint.

Isolated minerals, isolated vitamins, isolated glandular etc are in my opinion highly effected and in high doses often therapeutic and cannot be obtained in a whole food approach. Niacin, for instance, at fairly high levels is an excellent dilator and can be effective in warding off migraines.

Vitamin E (natural) the same for the cardio system.

Mike, I do consume an effective whole green drink and have been a whole food advocate for nearly 40 years and yet...I also use isolates.

Colloidal Silver is an isolate. One has to get it to high enough levels to make it work...so I just don't paint with so broad a brush as to eliminate the effectiveness of particular nutrients. I'm both "old school" and "new school." I'm a pragmatist and will use what works.

Best to you and wish you good health in 2014!!!

It's easy and cheaper to make your own with the ancient minerals crystals. I found the atrial fib came back again when I discontinued using the Mg chloride daily. It's stopped now that I take a quarter tsp daily again.

Magnesium chloride is amazing, it cures much more than just arrhythmia. If you're old and decrepit, take Magnesium chloride every day, or Massage it into your skin if you want to absorb more without getting an upset stomach.

I believe Magnesium "Chloride" to be the best commonly used magnesium to use.

I understand the body has to manufacture Chloride in order to use the Magnesium. Taking Mg with the chloride already "combined" does away with that need.

They say Magnesium chloride is the most easily assimilated into the body, even though it doesn't have as much magnesium as other varieties.

If you buy a $20 bottle of Mg chloride from the health food store it will last ages, because the most You can take without getting an upset stomach is a quarter tsp a day. Using the Magnesium bath salts (which is Mg chloride) allows you to make any strength you like, and also be able to massage large amounts it into your body without getting an upset stomach.

I believe this Magnesium Chloride has amazing benefits that people won't believe. If you have ANY of the common old age afflictions, Memory, bones, etc. Try Magnesium Chloride. if your diet isn't supplying enough magnesium (and you don't even know if it isn't, blood tests don't pick it up) you might be amazed. I am not exaggerating.

Hello, Mike I went out and bought the magnesium citrate and I have been having an upset stomach because I think I take too much, however it seems to work well with helping me digest. It feels better once I go to the bathroom because I feel lighter every time and never had that relief however it wreaks havoc on my stomach. I'm thinking of lowering the dosage and take it once a day. I almost will accept the upset stomach because I am having bowel movements more than once a day, any thoughts?

Hi Marie...Try buying plain old magnesium oil and just use it transdermally. You can apply magnesium oil directly onto your skin and at least 60% of it will be absorbed directly into the blood. This is a wonderfully easy delivery method to get magnesium into your body. You can even add a cup of magnesium chloride crystals to your bath water and it will be readily absorbed into the body.

Magnesium oil is just 70% magnesium chloride dissolved in 30% water. My own view is that magnesium chloride is, without doubt, the best form of magnesium to use because even doctors administer it to ER for patients by IV who have just had a heart attack. And it works like magic to take the strain off the heart.

You should be able to buy magnesium oil easily from internet vendors and from health stores.

Also, because you are taking the mag oil transdermally and not ingesting it, your digestion will not be disturbed. I also think that, because magnesium chloride is not so alkaline as magnesium citrate and when ingested, the mag oil will not cause problems with digestion as does magnesium citrate. Indeed, I think that you will find that magnesium oil actually helps your digestion because of its chloride content. The normal dose of mag oil with water is 10 drops twice a day with meals.

And as Mike has also mentioned, Ancient Minerals brand is a good one to use.

When I had heart heart arrythmias and dizziness some years ago, it was the combination of magnesium oil together with lugols iodine that cured that problem for me. That's because I was deficient in both magnesium and iodine in my own diet. I take magnesium chloride and lugols iodine now on a daily basis and haven't suffered any arrythmias, dizziness or any other heart problems in the last 8 years and I'm 65 y o. Even just taking kelp extract(contains iodine) together with the magnesium every day would probably help you more.

I have created my own magnesium oil spray with magnesium Chloride (Flakes) and a few drops of DMSO so the magnesium absorbs better - but I do get the burning/itching feeling - but it does subside after a while. After spending like two hours reading all the posts here on magnesium - I am left even more confused.

First question - should I not put the DMSO in my magnesium oil?

Second question: What other forms of Magnesium should I take? I will take two capsules (400 mg) of Magnesium chelate at night if I know for sure I'm not going to be using the magnesium oil spray. At any rate - instead of my thumbing through 5,000 articles on NIH or PubMed about Magnesium (some of which contradict each other), can anyone tell me which forms of magnesium I should be taking and how much?

Hi Marge,

You could make a gentle form of magnesium yourself at home which is easy on the stomach and extremely bio-available. It's called Magnesium acetate and is made with ACV or white distilled vinegar and (plain non flavored) milk of magnesia. You'll need to get the brand that has as its inert ingredient only water as some contain a bleach called hypochlorite. Dollar general and CVS for sure carry those but dollar general is only two bucks a 12 oz bottle.

Anyway, add 2 tablespoons of the M O M to a glass and then add 8 tablespoons of your vinegar and stir until the reaction is complete ( you'll know this has occurred when the solution is clear.) You may need to add small increments of vinegar say 1/4 teaspoon at a time to get the solution clear. (Try the white distilled vinegar first until you get the right ratio).

Your milk of magnesia should contain 1200 mg of magnesium hydroxide per tablespoon, therefore this 10 tablespoon batch will yield 1008.8 mg or just over a gram of elemental magnesium which you could put preferably in a sealed glass container refrigerated and dose yourself accordingly. 1 tablespoon = 100+mg magnesium. Work up to what works right for you.

Good luck

Editor's Choice

I have made some observations about magnesium that I thought I would share.

I have been taking magnesium powder (Natural Calm) at night for a long time. I take about 500 mg this way and it helps me to sleep and keeps my digestion regular. One night recently, I had had a snack and didn't want to drink the amount of water I would need to take my magnesium powder. I have some Nature's Way Magnesium capsules so I took two of those instead, which was a total of 800 mg of magnesium. I wondered if this would cause diarrhea because if I took that much Natural Calm, it surely would have. Well, it did not; in fact, the next day my digestion was noticeably slow. Whether it is because Natural Calm is a more absorbable form of magnesium (magnesium citrate) than the other, which was magnesium oxide, or something else, I do not know. But what that means is that not all magnesium supplements are equal. If one form of magnesium isn't working for you as you might hope, try another.

Secondly, I got lazy this week and skipped a few days of magnesium oil on my back at bedtime. Even with an oral magnesium supplement, if I skip the topical magnesium oil I wake up with stiffness. I made sure to use my magnesium oil last night and can really tell a difference - I was much less stiff when I woke up today. Some people find that topical magnesium affects the bowels, but it doesn't in my case, at least in the amount I use. But what is interesting to note is that internal use of magnesium does not have nearly the same benefit to me to reduce pain and stiffness that topical magnesium does.

What does this mean? If you want to use magnesium for a health problem, you may need to experiment with amounts you use as well as the brand you use, as well as the way you deliver it to your body (orally or through the skin.) And it seems there is no one size fits all. I guess this is where healing takes on its art form. There is a science to healing, but it isn't a once size fits all deal. Each individual is complex and unique in his needs, thus the art aspect of healing.

So, that is my two cents worth of musing on magnesium today...

I bought Ancient Minerals Mangesium flakes. I bring 1/2 cup distilled water to simmer on the stove in a stainless steel or glass pot. I remove it from the heat and add 1/2 cup magnesium flakes. According to some, this will not be as effective as store bought magnesium oil, but that makes no sense to me; I think it is an advertising thing.

I would guess magnesium flakes or oil from any reputable source would do.

I hope the magnesium oil will help your knees! It is great stuff.

M to M,

Some of the store bought mag oil is closer to 70% while a mix of a half cup of flakes to a half cup of water is more likely to be less than 50%. These 70% solutions are closer to a saturated solution and would tend to explain why they might be slightly more effective. Mixing flakes in lotion is another useful way of using mag flakes.

This is true, but remember that the magnesium is water soluble and the only way it will continue to absorb after it dries out, is if you add a bit more water. But, with the homemade version, it has more water, therefore takes a couple of minutes longer to dry out. This means it can absorb slightly longer and you don't get a crunchy residue as much. Doesn't matter really, because I just spray and apply, wait about 3 to 5 minutes and then do it again.

Liquid Chlorophyll is a much safer way to supplement with magnesium. Too much magnesium in tablet form will deplete essential trace minerals from your body. This happened to my husband he now only uses liquid chlorophyll for a magnesium supplement 1/4 to 1/2 tsp a day and hasnt had any problems since.

Dear Jb (NY),

I personally have never ever seen a liquid chlorophyll supplement that contains Magnesium in it. If you look at the back of every bottle of liquid chlorophyll it contains high amounts of copper sulfate.

In fact, in order to make liquid chlorophyll (better known as liquid chlorophyllin) the process actually removes the magnesium ion in the center of chlorophyll changing it's structure entirely and making 1 dose equal to 100% of daily value of copper.

I can attest to the fact that this supplement is extremely dangerous. 7 yrs & 2 mos ago I was poisoned by taking the recommended 3 doses of liquid chlorophyllin by Benevolent brand offered on Amazon. On that day, I felt it go directly to my brain. My eyes turned yellow and I had instant neuropathy in my hands and feet and was shuffling when I walked.

Since that day in March 2018, I have had permanent insomnia. I cannot fall asleep nor stay asleep EVER, without taking a drug to do so. Luckily, DMPS chelation, relieved me of the neuropathy, however, due to my previous yeast issues the DMPS chelation further destroyed my gut leaving me with leaky gut.

In other 3rd world countries that do not allow guns, copper sulfate, is the preferred choice of suicide poisoning. High doses cause the body's organs to shut down eventually resulting in permanent disability and eventually death.

I personally liken taking liquid chlorophyll due to it's high copper sulfate content comparable to drinking mercury. I've also experienced mercury poisoning from dentists that improperly removed 2 amalgam fillings at the same time.

Copper devices are used as birth control implants in the uterus of women. Before this was developed, they used to put 5 copper rods in a woman's arm to prevent pregnancy. The copper ions omitted from the woman's body not only disorient the sperm from being able to fertilize the egg (which is all I can find on the net now), but actually cuts the head off the sperm which is what I originally read about 5 years ago. NEVER EVER TAKE A COPPER SULFATE SUPPLEMENT OR ANY COPPER SUPPLEMENT. It is dangerous.

The late, Dr. Carl Pfeiffer MD, talked at great length on this in his book, Mental and Elemental Nutrients. He studied the mental patients and found that all had high copper to zinc ratios. Blood testing for Copper or Zinc should always be done at the same time to compare the ratio. Ratio should always be 1:1 when serum plasma numbers are divided. Anything higher will result in dysregulation of the delicate balance. Zinc supplements drive copper as well and can cause copper/zinc ratio to become unbalanced. I know this for a fact, as I have not only had my zinc/copper plasma tested 7 times, but have also had my husband's blood test as well. The only time it was not 1:1 for my husband and rose to 1:2 ratio is when he was taking zinc due to recommendations to avoid getting COVID. He immediately stopped taking zinc orotate, because of this.

What was your husband taking magnesium for? My severe leg and foot cramps have returned, and not sure why.

Hi Deb,

Two very common causes for muscle cramping are magnesium deficiency and potassium deficiency. Vitamin D deficiency, calcium and the B vitamin complex would also be of importance in the broader picture.

Magnesium chloride topical spray or lotion (Mag Oil) can often offer rapid muscle cramp relief in many cases when applied directly to the problem area. The RDA for elemental magnesium for women is 310/320 mg/day. The RDA for men is 400/420 of elemental magnesium. Magnesium glycinate is a useful choice as a bioavailable form. Here is a link to a typical magnesium glycinate product :

https://www.amazon.com/NOW-Supplements-Magnesium-Glycinate-Absorbable/dp/B0FXYLDGD1/ref=sr_1_4?crid=QN1WAF1LSRDH&dib=eyJ2IjoiMSJ9.to0pMfN9FsDjap30NQ7TDOCcRu3k7baAxbWI-X7Nbj8K49iyewNowuqLO9DyuS7zORg3PVrJ3uSnGfTV110iEM1CY7cpvGR_ezB1M1ki1HSBFRis95IJ1oPNo_4SbmfD86aaVho_las7AFEUZ9FrJJkeafXT1yFkvW8akK9fRnFPlG7zw6H3tASzik37zdgmqo8ofnYVUYfTy3K4p6R2tKAztKNT92I1Eqr_lr1x6e56hWLhBFW37E7897GsEHGXIccIwvF5sTqAr6JpF1-t-NcBGTtZ-QjXihTIT8wsr4I.fD2wrj2n_1-DZwFMq_18e8YM5PWVfddf0R6xjXqNa8k&dib_tag=se&keywords=Now+magnesium+glycinate&qid=1770765381&sprefix=now+magnesium+glycinate,aps,233&sr=8-4&th=1

Each of these tablets contains 100 mg of elemental magnesium, so a woman would need at least three tablets per day to get close to the RDA for elemental magnesium and get the remainder from the food you eat while a man would need 4 tablets and get the remainder from food. These would be minimal doses just to reach the RDA.

Here is a link to a typical mag oil spray :

Here is a list of potassium requirements for various people :

https://ods.od.nih.gov/factsheets/Potassium-Consumer/#:~:text=How much potassium do I, need?&text=Teens 14–18 years (girls), 2,300 mg&text=Adults 19+ years (men), 3,400 mg&text=Adults 19+ years (women), 2,600 mg

It is worth mentioning that other than via a prescription, over the counter potassium pills and capsules are only available in 99 mg increments so getting your potassium from food is a little more practical. Here is a link to a list of foods high in potassium :

JB (NY) I am aware JB wrote this years ago and will likely never see this. But for everyone else that reads this, they need to know that this information about liquid chlorophyll is incorrect. Liquid Chlorophyll is always in the form of Chlorophyllin, meaning the magnesium ion has been removed from the plant in order to be a liquid form and is replaced with copper sulfate. Please don't take my word for it. Google it. Research it. Copper sulfate is dangerous as is liquid Chlorophyll. It is not a source of Magnesium when it's in liquid form.

Malate is the easiest capsule form to assimilate. As Carolyn Dean says, if you don't get diarrhea, then it's working. No need to purchase expensive liquid ones when Malate works for Pennies a month.

After many hours of reading I bought the Borax and just started using it. I have had osteoarthritis in my thumbs for some time and it is slowly getting worse. Let's see what happens. However, my purpose here is to tell you about Magnesium. I have been using it for a long time but it didn't do me any good until I came upon a different form that has not been mentioned here. It is very hard to assimilate it in pill form. What I am using with success is Ionic magnesium citrate which is a powder that gets dissolved in a bit of hot water. It fizzles and the magnesium disappears into the water. This way it gets completely absorbed. Very effective. I get it in the USA, I don't know about its availability in other countries. I guess I am not supposed to mention brands, but I only know the one I am using. So, its not a tablet or a capsule or an oil, it is a drink. Hope this helps.

It all depends on the individual, so the best approach is a "broad spectrum" magnesium. Get as many forms as possible which may mean at least two or more products. Here are the forms to look for: Magnesium ---Citrate, Orotate, Aspartate, Malate, Oxide.

Hi Karen... I prefer to take Magnesium Chloride (as Magnesium Oil) for Magnesium and Apple Cider Vinegar (ACV) for malates. ACV contains both acetic acid and malic acid so when, as Ted from Bangkok advises, you add baking soda and water to two tablespoons of ACV this converts to acetates and malates which are then easily absorbed into the body from the intestines.

In my opinion, Magnesium Chloride is also the best form of magnesium to take and taking Magnesium chloride and ACV in this fashion will also be much cheaper for you. ACV is also high in potassium and other minerals so you also get that extra benefit too. The acetates and malates from ACV both also help to increase energy in the body. Also, malates in pill form are normally derived from a standardized chemical process. I don't like standardize chemical processes (think Codex Alimentarius). That's why I much prefer always using the natural forms or the bare mineral form as a simple powder only(no tablets).

Right now, because of the hot season in the Philippines, I also take 1/4 teaspoon of Vitamin C and two squirts of magnesium oil(large dose) every morning with my juice because of the searing heat. This somehow works magically to keep your body cool even in searing hot weather. I really don't know why or how it works -- you'll have to ask Ted -- but work it does!! I also take lugols iodine every day (6 to 8 drops a day) and this must also help to regulate body skin temperature more efficiently as well via the thyroid.

There are certainly other forms of Magnesium such as the malate, citrate and threonate salt forms which all have specific beneficial uses in the body. But the best all round form of magnesium to supplement is, without question, the magnesium chloride form because of its more widespread beneficial effects on the immune system, heart, increasing energy, nervous system, relaxing the muscles, regulating calcium in the body, relaxing the mind, antibiotic action, digestion etc.

Hi Leenot... Magnesium Hydroxide and Magnesium Oxide are both not very soluble in water. Being so insoluble -- these forms of magnesium are not good sources of supplemental magnesium for the body.

Magnesium Oil is a mixture of Magnesium Chloride crystals(60%) and water(40%). Magnesium Chloride is probably the best form of magnesium to supplement. Magnesium bicarbonate is another useful form of magnesium with a myriad uses, but this form is very hard to find. Mag Chloride can also be taken into the body and directly into the blood transdermally, when the magnesium oil is simply rubbed onto the skin. Here is some research evidence as to why magnesium chloride is so good and so necessary for the body:

Magnesium Chloride Use in Acute and Chronic Disease

Magnesium Chloride Product Analysis

I'm currently reading a book by Mark Sircus called Transdermal Magnesium: A New Modality for the Maintenance of Health and it is full of very useful and informative facts about magnesium chloride. The links above will tell you all about the history and usefulness of magnesium chloride.

Other forms of magnesium that you can supplement are mag citrate and mag gluconate -- but for me the mag chloride transdermal form(as magnesium oil) is still the best one to take.

Use 100% dead sea salts or combined with the pure magnesium chloride flakes in a soaking bath. Dead sea salts are cheaper and have other trace supplemental minerals including potassium with the magnesium chloride. Also buy in bulk and look for periodic sales with free shipping. I soak about 1 to 2 times weekly using 3 - 4 cups dead sea salts in a full warm bath for 30 minutes or so. Many benefits including control of athlete's foot, rapid healing of cuts and scratches from my cat, rapid recovery from muscle soreness, relief of minor pains and aches and the main heath benefits of better heart function, general good health, etc. Also enforced downtime to catch up on reading! One caution - don't use cheaper industrial mag chloride.

I am ever puzzled by why absorbing trace minerals through the skin is universally ignored in favor of oral supplementation or eating mountains of salads even when the need for supplements is recognized. If you have low magnesium you can't easily absorb ingested supplements anyhow, creating a vicious cycle. In my case I developed a serious magnesium and potassium deficiency running marathons and then supplemented orally for years with 500 mg. magnesium chelates without much effect. After I started soaking, heart palpitations disappeared and the other benefits made themselves felt over a couple of months of frequent soaking. If I miss a week I can tell the difference and it's always a pleasure to restore the soaking routine.
