In response to Robert (Manhattan, Ny) on 08/20/2012, who wrote:

"I found from repeated use, on and off, that higher doses of Vit D3 (1000 to 3000iu) results in a negative mood state... So instead I try to make an effort of getting around 10 to 15 minutes of summer sun daily. Another lesson to myself to remember that despite all the positive claims and current hype about a supplement or herb, one must listen to their body first."

Deficiency in D causes a deficiency in B vitamins which are needed for nerves, and mood. If you are low in B bits to begin with and supplement with D, because D stimulates repairs in the body, and Bs are also needed in higher amounts for tissue and nerve repair, a B deficiency can easily crop up. The fact your moods were affected is not a bad thing and neither does it suggest it was D vitamin causing it but rather more the fact you're probably deficient in B's too. In fact, B Vitamins are usually made by the microbes in the gut, but if those microbes get deficient in D, they die off and B vitamin production declines. It's the main reason why we gain weight in winter and drop a few pounds in Summer. Conversely studies show that when you supplement with adequate doses of D, you lose weight. That's becausevin addition to feeding microbes that make B's, it also increases insulin sensitivity, AND reduces insulin levels as a result. [Studies done in post menopausal women who had PCOS)

I'm writing to follow up on my vitamin D cure for insomnia report in February. After taking 2000 IU/day for 1.5 months I finally went to my doctor for a Vitamin D blood test, and it was 20 ng/ml, which is considered deficient. I also asked him why he didn't test me for vitamin D last year when I was having incredible trouble sleeping, digesting (I also had IBS) and managing daily life, and was told that insurance would not have paid for the test unless I had a "known" symptom of deficiency such as osteoporosis. However, insurance was very willing to pay for several expensive pharmaceuticals the doctor recommended me to try.


I am continuing to do much much better, am now taking 3000 IU/day D3, upping my daily intake of veggies, and also supplementing with ACV/honey, flaxseed oil, 500 mg vit C, and 200-400 mg magnesium citrate (I've read that vit D deficiency can go hand-in-hand with magnesium and potassium deficiency). My "sensitivity" to fish (rich in Vit. D and magnesium) has disappeared! No more IBS! I'm looking forward to some warm sunny spring days when I can get my vitamin D dose from the sun.

Pain, Fibromyalgia, Shingles

I learned so much from that Vitamin D book Robert Henry suggested that I read early 2017.

And I gave the D3 a Purposeful second go because of it. However for some reason I seem to soon forget the necessity of a supplement when I am feeling better.

I went on a vacation and when I returned I had forgotten why I was taking the Vitamin D. All I knew was once again my bones were achy, I started back on the MSM. Then I came across more information that stated that fibromyolgia is a Vitamin D3 deficiency. When I take the 10,000 to 20,000 IU D3 at least 5 days a week, I find it very energizing and when I get up in the morning I automatically stretch. When I don't take it, I do not get that stretch. I am 66 so I guess I need help to stretch.

And also other readings mention that Vitamin D3 taken at a 50,000 IU for 3 days lightens the pains of shingles. And I did try it and after 3 days tested it out by eating a good old peanut butter sandwich, I had no breakout and no pain.

Jan, I really miss the sun on my skin as fall is upon us. I tan as much as is reasonable while the sun is out and take vitamin K to store the D. Fall comes with shorter, cooler, darker days and rain ... but for me the autumn brings with it holiday pressures to make everyone happy .The media has put great subconscious demands on us to buy and decorate to fulfill the people in our lives. It sells products but does not produce healthy emotions. Most of the gatherings are filled with foods that are not very healthy and people stressed by the added pressures. I try as much as possible to get outdoors even in the cooler weather. We are body, mind, and spirit and our health improves when we address all the areas that affect us. I felt led to write this to you. Hope you find what heals you of SAD and fills your cup with joy overflowing. Blessings, Charity

Cofactors Critical to Vitamin D

Vitamin D and Why it May Not Be Working For You as Well as it Should

Many people take vitamin D because it is noted for many health benefits in hundreds of studies, but for some reason, some people do not seem to be able to obtain benefit from vitamin D. Many people are aware that there are cofactors for vitamin D such as boron, zinc, magnesium, vitamin K-2 and calcium, but we often do not realize how important these cofactors can be in terms of helping vitamin D to be all it can be for our health.

On that note, here is a very brief and easy to read article that clearly and simply explains why magnesium is absolutely needed in order for vitamin D to completely do the job it was meant to do in our bodies.

On a related note, the following very short abstract describes how not enough vitamin D and / or not enough magnesium can potentially create health problems for us!

Hi Jan...If it were me and I had SAD, I would take the following simple protocol:

Niacinamide (no flush) -- 500 mgs 3 times a day with meals. You can also safely increase this dose to 1000 mgs 3 times a day if it is helping. There are few significant side effects with niacinamide -- it's quite safe at higher dosage.

B50 Complex -- once a day with a meal.

See the research here:

Here's some more research by Dr Abram Hoffer, one of the Fathers of orthomolecular medicine, on the benefits of taking higher dose niacin/niacinamde for various psychoses and depression:

All about the benefits of higher dose niacin/niacinamide for the body:

I take at least 500 mgs of niacin (with flush) once or twice a day. Keeps my blood healthy, gives me energy, helps to prevent arthritis, Alzheimer's disease and diabetes 2 and also helps to keep me calm and happy.

I had a wart on my thumb. It was on the joint which made removing it difficult. Tried for years to get rid of it using compound w and sacylic acid. When I started taking 10,000 IU per day of Vitamin D3 after discovering I was deficient on a serum D blood test, the wart disappeared and never returned.

Calcification in tissue occurs in vitamin D deficiency. If you don't get enough, calcium is pulled from bone and the blood levels are high anyway. Taking vitamin D in sensible doses prevents this. It's the people posting about the higher doses and claiming calcium is high that really get me. Yes mega doses over long periods are dangerous. But the RDI is beyond a joke and causing many diseases. For one, if you get calcification Of arteries in deficiency then take doses to address that deficiency, stands to reason that calcium in arteries will be pulled out and put back into bone. And to do this it needs to be in the blood first. Would be handy to know what levels of blood calcium are TOO high, but I would say that when its dissolved from the artery walls with optimal doses, it goes into the blood to be cleared out and has a snowflakes chance in hell if actually adhering to much tissue thereafter. Even the kidneys would be shoving that stuff out. I doubt it could stick to ureters or kidneys any more than it could an artery. Heck calcium levels would have to be dangerously high or way above normal levels.

I got depressed on cod liver oil. Subtle blue feeling. Stopped taking and it went away. I am now taking D3 but with all the required co-factors. Mag, Bs, K, etc. Ok so far.

In reference to the cough...I have a friend here at work, age 58 who had been suffering from a bacterial respiratory infection since April of 2008. We work of different floors and I hadn't seen her in a while until she stopped into my office in the middle of January (Tues 1/13) of this year. She was still very, very ill. Whenever she tried to talk she would cough. It was bad.

I suggested she do the Vitamin D3 treatment....50,000 ius on the first day followed by 10,000 ius each day for a week and then 50,000 more for the following 2 weeks plus the daily 10,000. Guess what. She is cured. She had been on antibiotics and everything imaginable to get rid of this. She was sick for over 8 months.

Not only is her respiratory infection gone but she told me that she is no longer depressed and she has a great outlook on life again. Mind you, when I saw Cindy in January her skin was gray and she couldn't talk without coughing. Today looks completely healthy. I just went upstairs on a errand and I saw her in the classroom with students and the teacher she assists and she was laughing and healthy for the first time in almost a year. Vitamin D is an amazing thing.

Vitamin D is pretty unique to each individual and there is not a one dose fits all application for it. Generally if you carry a lot of body fat it can require significantly more vitamin D to reach a specific 25 OH d serum level than a person who has low body fat even though their weight may be equal. If you are trying to reach a specific 25 OH d level in the optimum range, the only way to do that and be sure is by having a 25 OH d test done. These can be done by mail with a pin prick test directly with a lab. This would be very important if you are trying to treat a specific health issue by getting your 25 OH d level into the upper end of the reference range (reference range: 30 ~ 100 ng/ml).

Some cancer studies suggest that optimal anti-cancer activity may occur around the 80 ng/ml level. Dr. Cannell suggests working your serum level up toward the upper end of the range for autism and even above if improvement continues, and then decrease the dose when no further improvement is seen, but again that would require regular testing by your doctor.

Some people just require more vitamin d than others to reach a specific serum level so it is more important to take whatever dose is needed to reach the desired serum level and test to be sure rather than choose a dose that may or may not achieve the proper 25 OH d serum level for you.


Vitamin D Side Effects

I know this is an old post, but some reading the comments further down the line may find this helpful.

It is recommended to also take the co-factors - magnesium, K2, boron, zinc, B vitamins, etc, when taking vitamin D, as they are apparently needed to support the D synthesis & to help orchestrate calcium in the body.

if calcium accumulation is already an issue (& you may not realise that until you start taking D), taking D without those co-factors may actually exacerbate the calcium issue.

Nothing works in isolation. Taking one element in isolation may potentially unbalance others.

High pasteurised dairy consumption may potentially lead to calcium accumulation (the beneficial microbes that generate certain necessary enzymes, vitamins & other nutrients needed for proper calcium distribution are no longer present), as may also calcium supplementation.

For the most part, most people are suffering D deficiency because of lack of sunlight actually. Hyperactive Parathyroid is due to boron deficiency from my reading. I'd say that most people out there know if they have not been out in the sun enough when considering the whole vitamin D issue and instinctively know they need it. Scaring people with your personal experiences (rare disease) is just not helpful

Apple cider vingar works with my blood pressure I had a bp of 200/120 apple cider vinegar just one dose dropped it down to 170/100 still extremely high. Now I am 6 foot 3 280 lbs and need to loose weight bad. I still take apple cider vinegar 4 tablespoonfuls once a day. I should do it a least twice but I don't and probably add some raw garlic. As I am athletic run two miles swim a mile and play sports. I am overly stress work the night shift and around obese people.

However vitamin d has worked better for me than apple cider vinegar. I take 5000 iu daily with magnesium 400mg and One a day vitamin for men. Vitamin D helps my immune system hypertension and regulates my insulin all at the same time. This vitamin D 3 works. Please check out Most americans do not get enough vitamin d because we are always in doors. It is really cheap at whole foods trader joes walmart even dollar general.

Please Please add vitamin d3 to your daily routine you will feel and see the difference.

I had the good fortune a couple of weeks ago when I was visiting Los Angeles to speak with an osteopathic doctor from Colorado who has treated and cured many of his patients with D3. The gist of what he told me (sorry, I didn't have any writing instruments with me at the time of the conversation so this is in my memory bank) was that many ailments are healed with vitamin D3 after 2-3 months on the hormone (he refers to it as a hormone, not a supplement). He suggested that I first get my D levels checked at a doctor's office. Once I know the baseline, I can start taking 8,000 iu of vitamin D3 a day. After 3 months, I should get the levels checked again. In summertime some people would be able to drop this daily dose to about 4,000 iu/day or less, but you won't know unless you get your levels checked. He told me people will be very surprised to see how deficient they are in D. Even those that live in sunny climates like Los Angeles are surprisingly deficient in D3.

One of his patients with erectile dysfunction was cured after a two months on D3. Unfortunately, the patient was so thrilled with the results that he started taking a lot more than what was recommended! A blood test showed his D levels soared too high and he had to come off it for about two months. After two months he was deficient again.

The good doctor also told me that 90% of his patients suffering from migraines were cured after being 2-3 months on D3. The key is to give it 3 months at 8,000/day dosage. He recommended the vitamin d council website for further research:

I have been in the healing profession (practitioner, researcher, advocate) for 30 years, nothing comes close to my experience with MSM, I am so sorry it took this long to try it. My chronic asthma gone in 3 days!! On albuterol for almost 40 years. I am in shock.

Some side effects which I consider to be cleansing symptoms: nausea, sleeplessness and skin breakouts, but I did start on a high dose of 20 grams a day. After three weeks no more 'side effects'.

My energy has greatly increased, I feel quite euphoric every day now. The only time I had that kind of euphoria was by drinking three glasses of organic green juices a day. I think people on heavy medications, mercury fillings, toxic diet are going to have more difficulties with it, so building up from a small dose with extra vitamin C and plenty of pure water will help.

The other supplement that really helps is Vitamin D3, I take 16,000iu liquid daily, no colds for two years now and my chronic bronchitis of 20 years has disappeared. Some years it was mild others, severe triggering serious asthma attacks. So the combination of Vitamin and MSM has been miraculous for me. This great website encouraged me to try MSM. Thanks so much.

p.s. Brushing my teeth with MSM has whitened them.

A 50,000 i.u. a month works out to 50,000/30 = 1667 i.u per day. A healthy person on a sun can easily produce 10,000 i.u. in a day. So the fact that giving 50,000 i.u. is like taking a 1700 i.u. vitamin D so that will have a minor impact on a vitamin D deficiency. Most unhealthy people can't produce 10,000 i.u. so they need supplements. But if supplements don't produce 5000 to 10000 i.u. from sun exposure it could mean some problems. As to woman with nursing babies they need about 2000 - 2500 i.u. A sick people I estimate needs at least 20,000 i.u. for people who have muscular atrophy. So the question works out to how much I.U. you need per day. The number is different. For example, in a condition of hyppoparathyroid, the dose required to normalize them is about 150,000 i.u. per day. In one case I remember a person with a muscular atrophy. The dose to reverse that required 20,000 i.u. for about a month. A person with a kidney problem (from lack of vitamin D) needed to get back in order required 50,000 i.u. of D3 for about a month. A good sun exposure will help increase vitamin D, but what's not mentioned is the long term trends in increasing UV radiation output by the sun has been also increasing.

So the issue is one of determining the right I.U. dose for a specific conditions. On the whole vitamin D works better if it's taken daily because in some instances, suppose your stomach didn't work that well on the day vitamin D was consumed, then it's not likely the body will absorb them. Plenty of things can block their absorption, a diarrhea, food poisoning, bouts of constipation, certain foods or gelatin may have blocked the vitamin D from absorbing, the capsules may not have dissolved completely in the stomach. It's my estimation that some people think taking only one capsule of vitamin D will last for a whole month because the body can store the vitamin D. But my experience has been that the vitamin D may not be properly absorbed on that particular day and I my end up missing my entire month of vitamin D. Therefore taking small doses is seen as more wise on the issue of absorption if one day I were to not absorbed, then I have the other 29 days to lean on.

For about 20 years, I had a chronic patch of psoriasis over my left eyebrow. I had tried several prescription and OTC creams, but none of them worked. After reading an article about how thousands of people got relief from psoriasis by sunbathing in the Dead Sea area, I remembered how my own psoriasis would practically disappear during the summer months when I sunbathed regularly. That was when I made the connection between sunshine and vitamin D. So, I started taking a daily supplement of 1000iu of vitamin D, which was in addition to the 400iu in my daily multivitamin. In about a week, I was amazed to see the patch of psoriasis had completely disappeared and has never returned. It may not work for everyone, but it sure worked for me!

Chronic Exhaustion, Asthma, Migraines

For me, Vitamin D is a MIRACLE. I have been on and off of the 50,000 iu/prescription-only doses and they did NOTHING for me until I stumbled upon an article about how unhealthy the prescription-grade is because it is lab-made and is actually vitamin D2. I did tons of research online and I can say that after ONE day of taking 2000 I.U. of vitamin D3, I felt AMAZING.

I have been telling EVERYONE about it and each person who has started taking it has had significant health changes.

For me...the chronic exhaustion is gone, I feel HAPPY, I feel like I can make it through the day! I wake up feeling renewed and my attitude is 10000% better. My asthma is MUCH better! A friend of mine suffered from chronic migraines all of her life and after two days of taking the D3, she feels amazing! Another friend had muscle spasming issues/constant aching and during the first day, she felt spectacular!

I'm not sure what else it will do for me but my skin is amazingly beautiful and clear! Also, I bent over to pick something up and to my surprise I felt NO pulling in my muscles! I used to be a dancer and was very limber, and this has returned despite the only change being Vitamin D3!!!!!! I could bend down to where my forehead touched my knees and I could touch the floor with my wrists!

I'm SOOOOO VERY BLESSED by stumbling upon the information I discovered and I am sharing it with the world!!!!

Ted posted his statement in 2006 and since then, so much more evidence has been released in great favor of Vitamin D. The TRICK is, stick with D3...NOT with D2!!!! ONLY cholecalciferol, NOTTTT ergocalciferol.

Once I get my next blood tests and determine whether my levels have returned to normal, I will then change my intake from 2000 I.U. of D3 to 1000 I.U. of D3.

I feel the best I've felt in ALL of my life and Vitamin D3 is ABSOLUTELY A HUGE PART OF THIS!

HI U GOOD PEOPLE DOIN, , , , , , ,

This may not come out too good, but think through it before you hit on me. On Oct 1 , we stop shaking hands at our little country church in Ten Mile. At first , the congregation was slightly irritated but some are now telling me that I'm smart.

We don't get much sun so we up our Vitamin D 3 to 5000 I u's /day. We stopped the flu vaccine years ago. Had you rather have the flu or mercury poisoning? Also , we shop stores before the crowds and know that there are a jullion germs on each buggy handle, door knobs, etc. So we carry anti-bacteria jels with us and wash our hands often.

Come April 1, we start shaking hands again, and cut back on our Vitamin D3. The Intelligent One created the sun which lets you make you own Vitamin D. Ain't that wonderful. Since I's not PC, I wish you all a Merry CHRISTmas. =========ROBERT HENRY=============

Vitamin D3 and Calcium

Hi Joe...It is possible that Vit D could cause a rise in blood calcium levels when taken in a high or excess dosage. To ensure that this does not happen, simultaneously taking magnesium and borax supplementation would certainly help to regulate the calcium/sodium/potassium balance within the blood/tissues, and thereby help to maintain the body in a more beneficial alkaline state (since excess calcium in the tissues causes acidosis).

Cod Liver Oil
Posted by Valerie (New Zealand) on 10/28/2017

NOTE: Some people are unable to convert betacarotene to retinol efficiently so if they rely on this variety alone for Vitamin A can become deficient in it. I'd say those that are vegan and have this issue need to find an oil containing retinol to supplement with. The fish Oil or cod liver oil variety is great source for non vegans or non vegetarians and needs no conversion.

I developed severe insomnia last winter (nov 07) and went through quite a trial for months, with none of the many things I tried helping much except some tips on how to improve sleep habits through cognitive behavioral therapy. I was doing better May-Oct 08 then all of a sudden the same severe insomnia symptom was back in full force. Last month I decided to try vitamin D3 2000 IU/day, after reading so many recent articles about the importance of this sunshine vitamin. I chose tablets with D3 source from lanolin, since I am allergic to fish. Within a week I was sleeping soundly at night, and I am continuing to sleep well. In retrospect, it is likely that I became more susceptible to vit. D deficiency after I became lactose intolerant and stopped drinking milk.

Found this website looking for flea remedies and found so much more! I too am always looking for remedies other than what are mainstream, just because it seems to me there has got to be more than one way to skin a cat, so to speak!

Read about Vitamin D deficincy in The Star Tribune by a doctor at the U of MN who discovered how many people suffer from a lack of it. Of course, I am a blue eyed blond who frys like a lobster in the sun and can't remember when the last time was that I went outdoors without sunscreen and and hat so I began taking a D supplement right away. I take 2000 IU of vitamin D daily. I have to say that I feel pretty darn good considering I have arthritis in all the major joints of my body.

I also have been using lysine to take care of my Herpes simplex outbreaks for years and would not be without it. I find that if I take 4-6 500 mg tablets at the first sign of the itch/tingle on my lip, and then 2 tablets every couple of hours after that, I can most times, stop it in its tracks and completely skip and signs of the break out. If I am nowhere near my supply of lysine and I get those symptoms, taking it at first opportunity causes the leisons to heal very rapidly. In any case, it works for me.

Am going to try the apple cider vinegar thing as well, for arthritis and for the flea problem. Weird that it will be for 2 such unrelated problems but If it works, who cares. It is certainly safe enough. Thanks for being here as a sounding board and gathering of natural remedies.

Contraindications - Sarcoidosis and Lyme

Health experts mention how beneficial Vitamin D is to a person's health. You have to be aware there are some conditions that do not benefit from vitamin D supplementations. Sarcoidosis is one and Lymes disease is another.

Explanation - Trevor Marshall was a biomedical engineer from Australia. It took him about 30 years to find out how cell wall deficient bacteria survive in the body for many years. He found out that they stimulate the cells to overproduce vitamin D. It becomes toxic and shuts the immune system down. Exposure to sun, vitamin D rich foods and supplements should be stopped completely for at least 12 months to clear the cell wall deficient form of borrelia. This helps tremendously the action of the antibiotics. Low doses of antibiotics become very effective. He advises Benicar (high blood pressure medicine) to decrease significantly the vitamin D in the body. Not all patients are able to take it. The majority of doctors and holistic practitioners advocate taking vitamin D without being aware of present microorganisms. Remember that fish oils and seaweed are high in vitamin D as well. They are taken by millions of people as supplements.

Most people have vitamin D deficiency that reflects in a blood test. Vitamin D could aggravate severely anybody with chronic Lyme disease and co–infections with CWD bacteria!!! Every person should be tested for these bacteria before administering vitamin D!!!
