New add: in a book of Dr. Clark she write to use 8 cups of olive oil and 1 gram of D3, ten drops a day for 2 weeks. Can Ted say if it is safe and how many drops to use? Thank you.

Why go back to shaking hands, just to feel the uncomfortable renewal of ceasing to do so next winter? Look at history, what we traditionally do isn't necessarily a good thing--and sometimes very clearly a bad thing. Why shake hands? Of what benefit is it? Why do we feel compelled to TOUCH a total stranger?? Even someone that isn't a stranger whose health we know is greatly compromised? I haven't participated in this hand-shaking tradition in years. I've also never had the flu and never get colds, and I'm very much over 40 :) To heck with tradition, health is so much better.

Given my recent discovery that most of us have MITES, and in greater numbers as we age, and they can cause serious health issues in those with compromised immune systems (includes so many of us), I'm now adamant about my no-hand-shaking policy. Touching others in loving ways is wonderful, but we should use great discretion in doing so (wash afterward at the very least when health of another is iffy). These mites stayed burrowed beneath the skin much of the time, feeding off of us. Mites love yeast, and if someone tends to be itchy and have flushing of the skin, they likely have an excessive (unhealthy amount of) both. Enjoy life, but we wisely wary, and above all, take care of yourself--both itchy and non-itchy ones ;)


Musculoskeletal Pain

About a year ago, a therapist suggested vitamin D for my chronic, nonspecific musculoskeletal pain. She recommended 4,000 IU of vitamin D3 daily. I got a little better but not much, and didn't associate it with vitamin D supplementation at the time. Then about a month ago I heard about the Vitamin D Council, a non-profit group of physicians and research scientists, and I went on their website.

Knowing from a recent blood test that I am somewhat deficient in vitamin D, and based on what I was reading, I immediately began taking 8,000 IU of D3, and what an improvement! In just a few weeks I am almost completely pain-free in the neck, shoulders, hips and knees. I don't believe it is coincidence because I've been dealing with muscle pain for 6 years now. I will drop back to the Council's recommended dosage in the next few months, at which time I can get some of my vitamin D from the sun.

If there really is a magic bullet, it could very well be vitamin D. It helps just about every aspect of the human body. If you don't spend much time outside, are in the habit of slathering on sunscreen, or if you live north of 35 degrees latitude, you are probably low on D. Please be aware that although this research appears to be solid, and I know for certain it has helped me, it isn't yet mainstream and differs considerably from government recommendations. It is important to have your vitamin D level checked so you have some idea of how much you need. It's also important to know that vitamin D supplements must be D3, which is cholecalciferol, the same thing our bodies make from sunshine.

Dear Earth Clinic:

I've recently started supplementing with 2,000 I. U. of Vitamin D nightly, before bedtime, in the hopes that it will help with my depression. The Mirena IUD ruined my emotional state (causing not only depression, but panic attacks, anxiety and ridiculous mood swings), and I've spent the last five years trying numerous supplements and "therapy" to get back to "my old self". Needless to say, I haven't had much luck. In any case, when I take the Vitamin D at night, I've noticed upon waking that I have a lot of phlegm in my chest; it takes me about half an hour to cough it all up. At first, I thought that it may either be due to a recent cold or the fact that I get recurring sinus infections. However, I remember reading somewhere that Vitamin D is good for the lungs, so I'm wondering if the phlegm is a good thing? Should I continue to take it? If so, should I decrease the dose or increase the dose?

Thanks in advance for your help!

Posted by Sandy (Bristol, Uk) on 12/18/2010

Sorry to hear how the mirena screwed things up for you. Vitamin D should be taken together with vitamin A to be effective. Check out the information backing this claim at the Weston Price blog

Good luck!

Cod Liver Oil

According to a recent newsletter from Dr. Cannell, yes, it does:

Myabe that is the explanation! And me thinking that cod liver oil was so very healthy...... I will read the article, I hope it explains why this happens and how to prevent it.

Vitamin D Side Effects

A few months ago, I was feeling a bit down and slightly depressed, perhaps due to the lack of sunshine during our rainy winter, and decided to take Vitamin D. I am pretty picky when it comes to my health so I selected a reputable brand of D3 (cholecalciferol) and started taking 6000 IU a day. First, my energy level increased and my mood brightened up but after hardly a week, I started feeling very tired, and not well. My legs felt very heavy, like if I had poor blood circulation; going up the stairs became challenging and my muscles were shivering - or felt like it. One night, I woke up, my body in spasm. This is when I stopped taking D3. All symptoms disappeared within 24-48 hours.

The 20,000 iu of D 3 has to be a mistake. Folks normally take 1,000 iu and a 5,000 iu dose during flu season, etc.

EC: Yes, thanks for catching it. Must be a typo. D3 is often sold in 2,000 iu/capsules unless you get a prescription from a doc's office for 50,000 iu (taken once a week for 1-2 months).

Just to tell you that yesterday I took one dose of vitamine D3 prescribed by my skin doctor as I was a bit high on vitamin A and a bit too low on D3. The dose, which is taken once every three or every six months was 100.000 U.I. On the box it is written Uvedose and Cholecalciferol.

Vitamin D Side Effects
Posted by Spunkymunky (Jabba Wankaleela, Shoobiedoobiedahdahdee) on 02/14/2013

The reason you were experiencing that is because a) You were taking D2 or b) You're not taking magnesium with it. Look up magnesium, vitamin D. Vitamin D creates a magnesium deficiency FAST, if you don't have enough magnesium as it is you'll get immediate side effects. It's not the D itself, it's the lack of magnesium. Also, if you don't take magnesium, Vitamin D won't absorb because it needs magnesium to do so. Magnesium chloride, "magnesium oil " is the best.

Vit D3 and Calcium


I remember reading about something Ted said where Vit D can easily become calcified under certain conditions. Would you know what situation he is referring to ? Thank You: Joe

Vitamin D3 and Calcium
Posted by Bill (San Fernando, Luzon, Philippines) on 04/15/2010

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).

Vitamin D3 and Calcium
Posted by Joe (Wellington, Fl) on 04/16/2010

Bill for general alkalizing would baking soda, potassium bicarbonate, and lemon be one of the better combos. My father is diabetic (type 2) insulin shots and his kidneys are not up to par. Would this help or act negatively on them? Any suggestion to support kidney function ? Thanks Again Joe

Vitamin D3 and Calcium
Posted by Bill (San Fernando, Luzon, Philippines) on 04/16/2010

Hi Joe...The kidneys are used to balance the electrolytes -- or minerals -- within the body. So although taking sodium and potassium bicarbonate with lemon is one of the best remedies for acidosis and will balance many body parameters, this will completely depend on the ability of the kidney to do its job properly. Therefore, I would not attempt this remedy if your father has problems with his kidneys without medical advice from a doctor.

Having said that, there is some recent research that suggests that taking just Baking Soda (Sodium Bicarbonate) with water can be beneficial to people with kidney disease. See these links:

Vitamin D Testing at Home
Posted by Deirdre (Earth Clinic) on 03/15/2010

Would love to know if anyone has tried this company for an at-home blood spot test for vitamin d levels? My husband's friend (a chiropractor) just emailed him this link. Costs $75 per test. This test is not available for residents of New York, unfortunately. And if you live in California, you will need to have a prescription from a health care provider before you can order the test.

Please send us your feedback if you've used this (or any other online company) to test your vitamin d levels. Thanks!

Vitamin D Testing at Home
Posted by Lori (Dayton, Oh) on 06/09/2010

I have used the ZRT tests for vitamin D, although I guess the price has gone up. It's a simple blood test - easy to administer. A few drops of blood and send it off. It took about 2 weeks for the results. I still have 2 unused tests. I take a daily supplement of D3 (and a high quality cod liver oil for vitamin A with NO problems maintaining a desirable level of D3 - I think it's a ratio issue)but I'll be vacationing at the beach this summer. I know my levels with supplementation; now I'm interested to see how they change with sun exposure exclusively.

One more thing, a discussion about vitamin D3 and calcium is not complete without discussion of vitamin K2 which dictates calcium deposition.

D3 and Cod Liver Oil
Posted by Cindy (Ch, Wi) on 02/28/2010

once again too much information can be sooo confusing. do we take cod liver or not and vit d or not? thank you, i do appreciate this information.

EC: Hi Cindy,

The research from the Vitamin D Council suggests not to buy D3 that contains cod liver oil. In the past I have bought D3 from 2 companies I found at Whole Foods and neither of them contained cod liver oil. After searching the brands of D3 found at iherb, I do not see cod liver oil listed in any of them. Just beware of cheap supplements! I thought I was getting a great deal at Costco and neglected to read the ingredients.

Good article on D3 sources here:

I have had a young woman living with me for several months. She was very pleased to find I had a wide variety of supplements available and started taking daily doses of most every thing as she was feeling run down and was in a great deal of stress in her life.

For a while she was feeling much better and we were both pleased. But for the last couple of days she started feeling much much worse which started to scare me.

Today she was in great pain throughout her body and was in terrible shape.

I kept wondering what was the matter, and on a hunch I looked up the side effect of excessive Vitamin D.

Her symptoms almost perfectly mimic the information I found on excess Vitamin D. and from your site I learned there might be a link to cod liver oil which is in the D3 from Costco.

This is scary because she is very sick.

Of course, I will halt all the Vit. D immediately but I do not know what else to do as she has no money to see a doctor.

From other sites I learned that a fair skinned person, which she is, can get enough Vit. D in 45 minutes in the sun in a week. She spend a great deal of time in the sun walking her dog daily etc. so I can believe she is way over dosed as she has been taking this vitamin in three sources as well as getting plenty of sunshine.

It would be good to list the problems here. The ones I have are:

"Ordinary doses can build up in the body over time and cause serious illness. Not surprisingly, the Mayo Clinic (are they defending themselves against Linus Pauling's accusations?) is the best source I've found on-line for vitamin D side effects. Here is their list:

Late symptoms of severe overdose (emerge after months or years of starting supplements)

High blood pressure
High fever
Irregular heartbeat
Stomach pain (severe)

Check with your doctor as soon as possible if any of the following side effects occur:

Early symptoms of overdose (emerge within days or weeks of starting vitamin D supplements)

Bone pain
Constipation (especially in children or adolescents)
Dryness of mouth
Headache (continuing)
Increased thirst
Increase in frequency of urination, especially at night, or in amount of urine
Irregular heartbeat
Itching skin
Loss of appetite
Metallic taste
Muscle pain
Nausea or vomiting (especially in children or adolescents)
Unusual tiredness or weakness

Late symptoms of overdose (emerge within weeks or months of starting supplements)

Bone pain
Calcium deposits (hard lumps) in tissues outside of the bone
Cloudy urine
Increased sensitivity of eyes to light or irritation of eyes
Itching of skin
Loss of appetite
Loss of sex drive
Mood or mental changes
Muscle pain
Nausea or vomiting
Protein in the urine
Redness or discharge of the eye, eyelid, or lining of the eyelid
Runny nose
Weight loss

I did read that Vit.A counteracts the absorption of Vit. D. Does any one have any other suggestions? Please be quick as this is serious!

Thanks so much,

EC: Hi Kristina,

Would you please tell us exactly what supplements your friend was taking? Thanks.

It sounds like a vitamin overdose, but I am not sure your friend is experiencing vitamin D toxicity. I also supplement with vitamin d3 (5,000 iu/day) and get at least half an hour of sun almost every day (South Bay, California - lots of sunshine). She should stop every supplement for at least 2 weeks and make sure to drink a lot of water to flush liver and kidneys. Add the supplements back in one by one. Let us know how she is in a few days.

Rosacea and Vitamin D

Have had mild rosacea for a year with broken capillaries on checks. Condition worsened considerably this past winter with pustules within red swellings appearing on face and neck in new places almost daily. I wondered why my skin was calm, with no redness, when I got up in the morning. I read a blog about Vit. D helping rosacea. Hmmm, I took my 1000 IU of Vit. D at night; perhaps that was why my skin was calm in the a.m., I reasoned. I started taking 1000 IU Vit. D when I got up in the morning as well as before bed. I noticed significant positive results immediately. My skin is almost entirely cleared up in one week, even the broken capillaries and redness in the cheeks has subsided. But the best thing is that the oozing pores and pustules have almost completely ceased. I still have maybe one pustule appearing per day, but it's isolated, and not like before where a 1/4" round area of my skin became very red with numerous oozing pores and one pustule within that area that took several days to calm down. I can't believe how easy this was. I'd read that rosacea is worsened by sunlight, so during this past winter I wouldn't go outside without sunscreen and a hat. My rosacea got much worse during this time period. I think I just got low in Vit. D. I'm 58 so that lower ability to absorb Vit. D may be part of it, too.

Vitamin D....My doctor put me on 50,000 units a month. Just one pill a month. I understand that's okay to take. Can you tell me how that works. Does one pill last a whole month? It seems to me it would be better to take a couple thousand a day. Also I sprinkle lecithin on ceral or salad every day and I take coq10 100 units three or four times a week. Would that be harmful to do. Would I be taking too many different things?

I'm just trying to stay healthy. Thanks so much for this site. A lot of very good info on here. I've taken advantage of a lot of it. Thanks again. Susan

Hi, Briana:

There are several kinds of COPD; emphysema, asthma, chronic bronchitis, and others. It may take a while to find the right combination for you. Try researching:

Chlorophyll Aids in clear breathing
Essential fatty acids For rebuilding and producing new cells
Zinc Protective effects on lung proteins.
DO NOT exceed 100 mgs daily from all supplements.
Copper 3 mgs daily Needed to balance with zinc.
CoQ10 Enhances oxygen in the lungs for use in the body
Free-form aminoacid complex Important for repair of lung tissue.
Grape seed extract 30 mg 3X daily. Helps protect the lungs.
Vitamin A Emulsion form is easier on the system.
Vit.C w/bioflavonoids Aids healing of inflamed tissue
Vit. E 200 IU daily Oxygen carrier and potent antioxident
Calcium and magnesium Chelate forms are best
Kelp Contains minerals needed for improved breathing and healing
Also, research juicing. It may help you get the nourishment you need w/o tiring you.

Hope this helps.
Peace, Sharik

Cough, Psoriasis
Posted by Tess (Palm Beach, FL) on 02/12/2009
4 out of 5 stars

I came down with the flu last week and a friend mentioned taking Vitamin D three days in a row and also putting hydrogen peroxide in the ear. I went a few days later when I was feeling better to Whole Foods and the only kind I could find was Vitamin D3. Most of the brands were made from liver sources, which I thought might be high in mercury, so I settled for vitamin D3 from Lanolin - also cholecalciferol. Anyway, I have been taking 1-2 softgels (2500 IU) a day with food. Immediately the raspy cough that I can't quite kick disappears. The amazing thing is that my psoriasis around my nose disappeared after taking the first dose. But both the cough and the psoriasis came back when I stopped a few days later. My thought is that I am not taking enough D3.

Question to those who know about Vitamin D3 -- How much is a good daily dosage? If it takes 30 minutes to get 10,000 IU from sitting out in the sun, I imagine you can take at least that amount. I am seeing that some people take up to 50,000 IU a day, but that seems a little high to me!

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.

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!

With all the hype around vitamin D3 nowadays, I thought I would try it. But this is my second time I've tried and stopped because I hate the way it changes my body odor, including my "female parts" and when I work up a sweat. Even my cats have noticed when sitting in my lap....

Perhaps it's because I rarely eat meat that I really noticed the change, but I can't tolerate it. I feel really animal-ly. I noticed my libido increased a bit and I had a touch more energy, but it's not worth it for me. I'll just try to get more sunshine in the winter.

Vitamin D & "female" odor.

Mussen, You will have to use a tanning booth to get sunshine at your latitude in the winter months. You can stand outside all day, stark raving naked in Canada and the sun can be high in the sky.... and you won't make one ounce of vitamin d. You really need to do more research in this area. Canada is one of the few countries that is doing credible research on vitamin d. I really hope you take the time to check this out.

If you would like good information you can check the web site or visit

These are both not-for-profits (sunshine is free and the supplements are cheap so nobody is making money).

There is a LOT of research indicating that vitamin D supplements are safe up to 10,000 IU a day... Unless you have Crohns, irritable bowel syndrome or certain immune deficiencies. Check your blood level in the middle of winter after taking three months of a supplement. This will indicate whether you are getting enough vitamin D throughout the year to support calcium absorption.

Yeah, generally: one should take between 13 I.U and 34 I.U of vitamin D3 per pound of body weight. I'm pretty sure I notice that the 'dry' form of D3 is more potent than the lanolin kind, too. Joseph Mercola once wrote that some organization or something thought: we can take up to 35 I.U per pound of body weight. I've done some of my 'homework' though, and found out: that's too high.
