Vitamin D and Bowel Problems
by: Kerri Knox, RN-The Immune Health Queen!

Hi Stan,

The amount of Vitamin D that you are taking is such a ridiculously low dose that it seems like it would be impossible for you to actually have any problems from the vitamin D itself.

More About Vitamin D

It is more likely either the soybean oil (which can go rancid if it's been sitting on the shelf for long periods of time) or something else in the pill container itself.

But in thousands of studies, researchers remarked on the fact that there were 'Remarkably' few side effects. In these studies, researchers always use VERY high quality supplements and that makes a HUGE difference over pills that have been sitting in stores for an unknown amount of time and made with who knows what.

The other issue is that you are taking about ONE-HALF the dose that up to date doctors, like Dr. John Cannell of the Vitamin D Council, are recommending for newborns.

Let me repeat that. You are taking HALF the dose recommended for newborns!

You may be shocked to see how much vitamin D you might actually need to make a difference in your health. Read my page on Vitamin D Requirements and then go out and get a
High Quality Vitamin D3 Supplement with a clinically significant dose of Vitamin D3 (make sure that it has the "3" or says Cholecalciferol).

Me, too.

I've been taking vit. D in soybean oil for about a month and have had the same experience.

calcium with vitamin d
by: Anonymous

I took a calcium plus vitamin d supplement for about 2-3 weeks and have had diarrhea for about 6 weeks.

I've recently started to feel better but I'm still prone to it.

does Vitamin D kill parasites?
by: Anonymous

I am starting to wonder, for reasons I won't go into whether when you up vitamin D it kills parasites in your intestine track and causes you to get montezuma's revenge as the parasites die...

Just a thought... I mean if Vitamin D can be toxic, surely a sudden increase would be fatal to small creatures living off you.. no?

the same experience
by: Philla

Have been taking 5000 IU of Vit D3 for some weeks with chronic diarrhea for several weeks as a result. Also I have spotted many nasty critters in my stools, so the possibility that the Vitamin D3 acts like a cleansing agent or immunosupportive supplement seems to be there.

It contains cathelicidin, which is supposed to declare "war on pathogens and viruses" and support the immune system..

I was taking Viactiv twice a day 500iu of vitamin D in each dose which was a chewable. Ingredient lists coconut oil. I got terrible diarrhea and had lots of gas so had to quit taking it. Looking for info and found this site.

Why are you taking Viactiv...
by: Kerri Knox, RN- The Immune Queen!

So, I'm curious why you are even TAKING viactiv? It's CANDY, it's NOT a supplement!

Even twice daily viactiv has only 1000 IU's of vitamin d- which, if you read my Vitamin D Dosage page, you will see is the correct dose for a newborn infant and not an adult.

You need about 4 times that to meet your needs.

Second, I read SEVERAL different websites and every single one of them that lists the ingredients of viactiv do NOT list coconut oil, but HYDROGENATED or PARTIALLY HYDROGENATED PALM KERNEL OIL.

And if you are not aware of it, the term 'Hydrogenated' and 'Partially Hydrogenated' is the same as the word 'Trans Fat' which is one of the most horrible substances for your health that you could possibly be ingesting. They have already BANNED trans-fats in some countries as a health hazard- and you are taking it purposely- along with corn syrup and artificial flavors as a HEALTH SUPPLEMENT!!!

It's no wonder that you got diarrhea with all those terrible things for your body in that. Your body is BEGGING you not to take that stuff and is attempting to expel these bad ingredients out of your body.

Not only that, but the calcium is in the form of calcium carbonate. So, you are not even absorbing the calcium anyway!! So, why are you taking it?

Help, I have the runs!!@@
by: Anonymous

I was given by my doctor 50,000 units of Vit D on Friday and on Wednesday total 100,000. I got the bands feelings in my joints so bad I could not walk.

So I went down to 50,000 units once a week on Wednesday, all was well. Doctor took another blood test and he said I was still low. He was going to have me go back up to 100,000 but I am scared. So I ordered 5,000 units for every day except Wednesday when I took 50,000 units.

Now I am up to 85,00 units a week plus my Calicum plus D every day and my multi vitamin. so I am close to 100,000 units a week. Now the runs !!!@ is this temporary???

Ohhhhhhh my... Help @@@

Vitamin D3 reaction?
by: Susan

I have been told constantly by my endocrinologist, that Vitamin D3 doesn't cause any side effects. I have been having diarrhea and intestinal cramping, ever since I started on the Vitamin D3 therapy.

The endo doc originally had me taking 50,000 iu's one time a week, but that really made me feel ill. He thinks that the increased Calcium I am now taking (had low Vit. D, but Blood Calcium Levels appeared normal on my blood work) due to a positive test for high parathyroid hormone, has caused my discomfort.

I only take 600 MG. of Calcium in the a.m. and 600 MG. in the evening. It never bothered me before? Seems like anything toxic, is now making a quick exit out of me. Does Vit. D3 tend to have toxic cleansing capabilities?

Any information at this point would be welcomed, as I must remain on the Vit. D3 and Calcium. Thank You!

Toxic Cleaning
by: Kerri Knox, RN- The Immune Queen!

Well, the first thing that you should try is a new vitamin d formulation. As I mention on the Vitamin D Side Effects page, the very first thing that I have people change when they have any 'odd' side effects is the formulation.

Many vitamin d3 capsules are made from poor quality oil that could be rancid- and which would absolutely explain your symptoms.

So, please get a no oil Dry Vitamin D3 Supplement like the one that I offer because of that reason- and see if that helps.

Vitamin D
by: Anonymous

I had a D level of 9 so clearly I need supplementation However when I first started taking the supplements I was prescribed the green fishy smelling green capsules which caused cramping and diarrhea.

I now take a powdered capsule and it has cut down on the GI problem. I also just realized I have a allergy to shellfish fish is often stored with shellfish and can cross contaminate D is often or maybe always derived from fish could this be the problem?

Any thoughts?

Fishy Smelling Capsules
by: Kerri Knox, RN- The Immune Queen!

None of the vitamin d that I have ever taken is 'fishy smelling'. I would suspect that the vitamin d that you were taking had oils that had gone rancid and hence the foul smell.

Never take ANYTHING that has a foul smell. Especially when it is an oil. It might be rancid.

I don't know about the shellfish issue, but there are some vitamin d preparations made from lanolin rather than fish.

But many, if not most, vitamin d side effects can be eliminated by taking the Dry Vitamin D Supplements along with magnesium.

50,000 iu 2 x a week causing diarrhrea
by: frogeyd

I have noticed I am having lots of stomach problems also since I started my prescription. My capsules are green and have a slight smell to them but not a rancid smell.

I took them after I had cereal and don't think that was enough of a buffer. However, I was tentatively diagnosed with Fibromyalgia as well.

I tested negative for Celiac Disease per my R.A. doctor. I am starting to wonder if these high doses are just too much for the body all at once?


frogeyd (my vitamin d deficiency was a 13)

Maybe, but I'll bet you need new supplements..
by: Kerri Knox, RN- The Immune Queen!

Hi Frog,

These doses have been given safely for decades and 600,000 IU's are given to children with rickets all at once. As well, for almost a decade every child born in East Germany was given 600,000 IU's at birth and every 3 months for the first 18 months of life.

While everyone is different and there certainly ARE people who are going to have reactions to Vitamin D, but the fact is that the vast majority of people do not- and in studies, almost no one does. And the reason that I believe people in studies don't have side effects when I find that so many people in 'real life' do- is due to the quality control used in the supplements in studies.

So, as far as quality control is concerned, your capsules should not smell like ANYTHING, and so I am willing to bet that you are having a reaction to the oils in the capsule. NONE of my clients have these type of reactions because I insist that they use no oil supplements or a specific brand of olive oil containing supplements- and many people who have switched to 'Dry' (no oil) Vitamin D3 Supplements that I offer on my site have told me that their negative symptoms have cleared up after switching.

Vitamin D Spray for Immune Health

In addition, taking Prescription Vitamin D is just simply NOT recommended and it would be better for you to switch anyway. Please get off those capsules that have an odor and replace them with no oil capsules.

I get frustrated because so many people believe that the Vitamin D itself is causing their problem when it's the low quality ingredients used- and I'm trying to change this through education. I'm betting that you see a difference when you switch. PLEASE come back and let me know...

Dry Vitamin D and Diarrhea
by: Kandy

I have also been diagnosed with low Vitamin D levels and have been taking 2000 IU of Vitamin D3 daily for 3 weeks now.

I am taking 2 pills of Vitamin D3 "Life" Brand Dry Vitamin D3 which contain no oils. (I live in Ontario, Canada - this is the Shopper's Drug Mart Brand). It also contains Calcuim Phophate Dibasic Dihydrate, Mircocrystaline Cellouse and Magnesium Sterate.

I felt nauseated for the first few days of taking it and now I have lots of gas and diarrhea with cramping over the last two weeks. I am wondering if the amount I am taking is too much or if it is something that will just pass as my body adjusts.

Any information would be helpful.


It's NOT a High Dose..
by: Kerri Knox, RN- The Immune Queen!

Hi Kandy,

Your dosage is NOT a high dose, so you can rule that possibility out. In fact, if you have low vitamin d, then 2000 IU's is NOT going to help that and in fact your level will likely to continue DROPPING because it's such a LOW dose. Please take a look at the page on Vitamin D Requirements page and you'll see that the dose that you are taking is a MAINTENANCE dose for a 50 pound child.

A 'standard' dosage for Vitamin D Deficiency Treatment is 7000 to 10,000 IU's per day- sometimes even more is necessary to bring levels up to normal.

But back to your issue. Before you write off vitamin d as causing your digestive problems, the first thing to try is to make sure that you are taking your vitamin d with food and that that food has some fat in it.

I also urge you to try getting a 'professional' brand Vitamin D to see if that helps. After so many years of having no problems with the brands that I use, yet having so many people writing in with problems with store bought brands, it could simply be some filler or 'cheap' ingredient that your brand has in it.

Even if it's not a 'bad' ingredient, it might just be something that doesn't agree with you. Gelatin is a 'natural' ingredient, but some people may have problems with it anyway, so just try a couple of different 'professional' brands with different ingredients before you give up on vitamin d.

There is a SOLUTION to this problem. Please follow these VERY simple steps to end this problem. Since the cause of this problem is NOT the Vitamin D itself, but the ingredients and carriers in the vitamin d in nearly ALL cases, then:

1) Make sure that you take your supplement with food and NOT on an empty stomach.

2) CHANGE TO A NO OIL BRAND: Simply change to a 'professional' brand with NO OILS such as the Lonevity Plus Vitamin D3 Supplements that I offer to you for EXACTLY the reason that Polyunsaturated Oils and all other types of oils go RANCID over time and this is the problem that causes diarrhea in 90% of the cases.

2) IF THAT DOESN'T SOLVE THE PROBLEM: It's not ALWAYS the oil that causes these problems, someone has a sensitivity to individual ingredients in EVERYTHING. Compare the ingredients of the two formulas that have both caused you problems to see what common ingredients that they have and find a formula WITHOUT those common ingredient2 in it.

Remember, if you can get sunlight without getting diarrhea, then it's NOT the vitamin d, but something IN the supplements. In hundreds of studies of vitamin d, ZERO people have had this problem. This is likely because studies use HIGH QUALITY FRESHLY PREPARED professional supplements.

The makers of the supplements get a little bit of advertising for these studies and so it's in their best interest to provide studies supplements of exceptional quality that few people will have side effects from.

In my personal experience of helping HUNDREDS of people with vitamin d, I'm NEVER had anyone with this problem either. The ONLY people that I EVER hear of getting this problem are taking 'Store Bought' supplements.

It's the soybean oil
by: Anonymous

It's probably the soybean oil causing people to get sick/diarrhea from vitamin d3 with soybean oil. I get diarrhea from soybean oil (took years to figure out and lots of trial and error). I am meeting many people who have the same symptoms. The odd thing is some of us can eat other soy products without getting sick... and we can even eat expeller pressed soybean oil. Still researching what about the soy oil causes diarrhea, but it may be the chemical extraction process which uses KNOWN toxins hexane and or benzene and who know's what else. To know for sure, you will need to run your own tests with lots of trial-and-error. watch how you feel after eating a salad (most salad dressings contain soybean oil) or fried food or store-bought pastries. Soybean oil is usually sold as vegitable oil. Welcome to the modern world and modern food where corporate america profits at our health expense.

rancid soybean oil..
by: Mary

Is sunflower oil better than soybean oil in D3.Have been taking D3 with soybean oil for 3 years and have had constant diarrhea and indigestion..Couldn't believe it was caused by my D3 (since I am a D3 junkie) eleminated every vitamin except D but still had the problem..finally "gave in" and stopped D and everything was sure it was the soybean oil which became now taking D with sunflower oil and hoping the problem doesn't return.



by: Anonymous

I have been searching for a cause for my recent chronic diarrhea. A couple of months ago (before diarrhea) I started an elimination diet and added pharmaceutical grade supplements including D3 (50000) After the initial 3 weeks of just vegetables, fruits and light protein I added back in some other foods one at a time. Since adding food, I’ve developed chronic diarrhea. I have been thinking I’m intolerant to just about everything but I thought I’d check into the supplements I added in and I found out D3 is most often made from lanolin and I’m allergic to wool. There isn’t much information on the correlation between the two but I’m discontinuing the D3 today!! There are vegan options available that I may start sometime but I am hoping my gut will heal and problem solved. As a side note I have problems with lip balms and sunscreen too, this also could be a lanolin reaction. I hope this helps even one person! Good luck!

yes, they contain lanolin
by: Kerri Knox

Yes, most Vitamin D supplements are derived from lanolin. You can use a Lanolin Free Vitamin D Supplement to avoid any future problems.
