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!!!

Hi Valerie,

Thank you for your very informative post in 2017 about Vitamin D and the Bs. Could you tell me where you got your information? I'm studying and will soon implement Dr. Gominak's RightSleep method of supplementing with Vitamin D and the Bs and your information sounds exactly like hers!

Vitamin D Side Effects
Posted by Ali (Wales) on 11/09/2021

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.

It's pretty ridiculous not shaking hands and even worse, using poisonous products to kill bacteria (sanitizers) The world has gone utterly mad and fearing a microscopic enemy. It used to be terrorists but now it's a phantom virus. Really people, your body was made to handle almost anything. Exposure is key, if you don't expose your body to all combinations then it's not going to read mutations. Mutations always occur and they occur in the body too. Keeping away from people, keeping away from germs is bad for you in itself. It's better to expose yourself while you're in good health because your immune system learns that way. It only makes it weaker by keeping away from real life.

Bill, thanks for the suggestions. I will enjoy reading the sites that you included in your post. I do have niacinamide. I'll get right on it. The B complex too. Thanks again for taking the time to help me out. It's really appreciated.

Thanks, Charity. That was a very sweet reply and so appropriate. We are having an extremely dark gloomy day today and I've just tried to keep in mind how very fortunate I am. And yes, the holidays can be an anxious time, but as I've gotten older, I've given up a lot of things I used to do and let the kids do them now. I do know, that after three or four dark days, it really can get to me and throw me into anxiety/panic attacks. My mood starts to go downhill in late October and get better every March. Thanks again for reminding me to smell the flowers.

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

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 am totally convinced that I am suffering from SAD. I was wondering if anyone had any suggestions. I'm looking into getting a therapy light and also wondered if anyone had any suggestions on that. I've searched the internet and there are so many. I do supplement with vitamin D, magnesium, b complex and all the rest of the vitamins and minerals. I try to eat healthy most of the time and exercise (although I need to do more). I do miss the sunshine:(

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!


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.

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...

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)

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

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.

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 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.

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.

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.

Vitamin D Side Effects
Posted by KT (Usa) on 08/20/2015

Hi Gemma, I would suggest getting some magnesium powder from the HF store. Dissolve about 1/4 tsp. in OJ and drink it with or after a protein meal. Preferably after having eggs for breakfast.

Magnesium binds with protein before it is absorbed (Nutrition Almanac). I have a long history of injuries, reported degerative disc disease and joint pain that has been relieved after adding the magnesium powder to my diet. Staying away from contributing factors such as hidden sources of MSG (a nerve stimulant) is important but with today's tainted food supply it can be difficult. Sometimes the binders and fillers in supplements contain hidden sources. I cannot ingest a gelatin capsule without problems. The capsule alone contains 11-13 mg. of MSG. I had been told that magnesium can offer some protection against the toxic effects of MSG.

It would also be very beneficial for you to get a few minutes of sunlight every day. It is reported in a Nutrition Almanac that 15 min. a day, several days a week does not pose a toxic threat and could provide you with what you need for health. The almanac also reports the sun coverts cholesterol to vitamin D.

I took 10,000iu of vitamin D3 plus a k2 supplement for 3 weeks and developed nasty side effects. My joints all started clicking, my knees became painful and my muscles started twitching. I could also feel a weird sensation in my teeth and had lower back pain. A muscle allergy tester diagnosed calcium deposits in all my joints and tendons and recommended phytoplankton 3 times per day and ACV 3 times per day. I have been taking these for 2 weeks and have had slight improvement (I'm not twitching much anymore). I added a magnesium oil yesterday which appears to have helped my back pain.

But my joints still click (everywhere! ) and my tendons are painful. Other people on vitamin d forums have mentioned their joints clicking too. Have you got any suggestions? Should I try the chanca piedra? I'm scared to put any supplements into my body anymore.

Best Wishes.

High doses of Vit D will deplete your magnesium so, I would suggest magnesium chloride in liquid form. Add the suggested amount in a very large glass of water and sip it throughout the day to get maximum absorption and reduce chances of diarrhea. The hard pills generally are not absorbed well from what I've read. Good Luck.

Vit. D(3) is not a vitamin but a hormone. There are 4 ways to get vitamin (hormone) d3:

#1 sun, #2 veggies, #3 fish oils like salmon, codliver, sardines #4 made from lanolin, which includes sprays, liquids, lotions, pills and mouse poison.

One must be very careful taking d3 as it stays in the liver for 3 months, causes the blood to thin, and allows the calcium to get into the blood stream causing clogged arteries, calcium to deposit anywhere it wishes. Look it up.

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.

I have AS, diagnosed nearly 8 years ago. I have tried everything and stumbled upon something that has made a remarkable difference to my pain. I have been taking a supplement with vitamin d3 1000iu per tablet, boran(from borax)1mg, selenium 50mcg, and natural vitamin E 33 mg. I have been taking this supplement two mid morning and one in the afternoon. At the same time I am taking red algea (lithothamnion calcareum) 500mg, twice a day (taken at same time as red algea). Before trying this, talk to your Dr, not everyone is vitamin D difficient. I avoid the sun as I am fair skinned and burn easily.

This is to Kristina from Munich, Germany - If your body is deficient in magnesium, it will not properly utilize vitamin D. Blood or urine tests are often inaccurate, as only 1% of magnesium is found there. I was found to be vitamin D deficient, but it wasn't until I started supplementing with magnesium citrate powder (mixed in juice) for a week or so that I could take vitamin D without other side effects. Check out this link (when you get to this page, move down just a little bit to the section titled: Magnesium and Vitamin D):

You must look at your calcium levels; Get these tests or past blood work results: Calcium- Vitamin D and P T H... This is the parathyroid hormone level which controls calcium levels. D is a response of calcium levels!!

Low D is the body's way of protecting itself from heart damage and stroke due to high levels of calcium, it may only be slightly elevated. Taking D will hurt your heart and cause edema when you have eleveated calcium.


PTH (parathyroid hormone) is the control module for calcium, consider it a thermostat for the body, it is a hormone gland behind the thyroid; it is so important you have four redundant glands that all do the same thing, but only one works at a time.

I had the same problem, was found to have high PTH. Causing high calicium and resulting low D. Reg. Docs all tried to make me take D... HUGE MISTAKE, ok... seriously! My D was only 7-11; It is important that you STOP D, you are harming yourself, doctors can be such idiots!

Go to; read all about it. It was a simple fix, high calicium (mine was never that high but 9. 8-10. 8; my D 7-11; my PTH 90-110; I had one benign parathyroid adenoma... They are benign 99 percent of the time; it is not cancer, dont go there in your mind. My sestamibi scans were negative, dont get caught in that... Oh we cant see it so it doesnt exist, these glands are the size of a grain of RICE ok... Trust no one except the Norman Parathyroid center to get it right if you have high Cal, even a little; or borderline, high PTH and low D... Those three tests alone are enough to diagnose the ademoma without even seeing the bugger!

Have the surgery only the M I R P, minimally invasive, ( I had to go to Tampa and see Dr. Norman, as all others told me it was cancer and it ALL HAD to be removed, including my thyroid and part of the trachea... WRONG... With a very invasive surgery and a life dependant on drugs to survive... NOT THE CASE AT ALL: its outpatient, it takes half a day, and its done. Thyroid nodules were benign as well! They were causing me to be hypothyroid!

The disease is called Bones, STones, Moans, and Groans; If you have achy joints, (I never had stones) been told you have osteporsis developing or osteopenia, high BP , high Cholesterol; GI problems;... Then get this sucker removed; Symptoms of chronic malabsorbtion; all; and changing your diet is the only way to stop these diseases from progressing and developing tumors!

Now, for the cause of this I have finally arrived at FRUCTOSE MALABSORTION; and GLUTEN intol; I have gone gluten free and LOW FODMAP (eliminating foods with high fructose amounts, this includes sugar free additivies, wheat, onions, garlic, apples, honey, HFCS; etc.. With my foods,

the adenoma is a symptom of chronic malabsorbiton, (wiki that) you must find your intolerences and avoid those foods, this is the only cure, I say again, the only cure! Avoidance... Just like a bee allergy, you must not get stung by foods you cannot process, endocrine disease is the result!

- The same swelling a bee sting causes externally is what is happening in your gut (small intestine) and the villi become damaged, cannot uptake minerals from foods, vitamins will NEVER cure this, in fact they will make you sicker!

Sincerely, all my best, Lori PS: Remember medications have fillers, binders and colors that can make all symptoms worse, they did for me everytime. Avoid All colors and dyes, check personal care products, for wheat germ oil; sorbitol; mannitol, etc.

Try going low lactose; real butter hard cheeses only, lactose free milk, no yogurts; no soft cheeses at all; go gluten free; avoid all wheat products (go to for symptoms and lists of unsafe ingrediets, like MSG, INULIN, modified food startch, etc; Low fodmap foods , avoid apples, pears, cabbage family, some types of beans, no pasta, no breads. (LOW FODMAP) Seek out Shephard works and Wiki on Fructose Malabsorbtion, up to 30 percent of caucasians have it, especially euro decent!

When I keep taking the vitamin D the bags get worse by day, and I get very tired.

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.
