why does my body not absorb vitamin d

Vitamin D is a nutrient that your body uses to meet a variety of critical health needs, including maintenance of your normal nerve and immune function and the support of proper bone formation. You can develop a deficiency of this vitamin if you donБt absorb it properly in your small intestine. Potential reasons for vitamin D absorption problems include fat-absorption disorders, the presence of certain other diseases and the after-effects of gastric bypass surgery. Vitamin D belongs to a class of nutrients called fat-soluble vitamins. As the name implies, you need dietary fat to help break down these vitamins and absorb them into your body. Outside of fatty fish, egg yolks, cheese, beef liver, fish liver oil and certain mushroom species, vitamin D is scarce in natural foods. As a result, most people in the U. S. rely on milk, orange juice, cereal and other artificially fortified foods as dietary sources of the vitamin. Additional amounts of vitamin D come from internal chemical reactions triggered by direct exposure to the ultraviolet rays in sunlight.


Since you cannot absorb vitamin D into your system without an accompanying intake of fat, any disorder that disrupts your ability to absorb fat can also disrupt your ability to absorb vitamin D, according to the National Institutes of Health Office of Dietary Supplements. Potential sources of fat-absorption problems include certain forms of liver disease and mucus buildup in the digestive tract associated with the lung disorder cystic fibrosis. You can also develop fat absorption difficulties if you have a gastrointestinal disorder called CrohnБs disease. The presence of CrohnБs disease can also directly affect your bodyБs ability to absorb vitamin D, according to a study published in 2011 in the CrohnБs and Colitis Foundation of AmericaБs official journal, БInflammatory Bowel Diseases. Б When compared to people who donБt have CrohnБs or any other gastrointestinal disorder, the average CrohnБs patient absorbs roughly 30 percent less of the vitamin D present in his or her diet, the authors of the study report.


However, not all people with CrohnБs experience the same degree of difficulty in processing their food, and doctors must perform tests to determine the effects of malabsorption in any given individual. If you are obese and undergo gastric bypass surgery, your food will typically be routed around part of your upper small intestine. Since vitamin D absorption takes places in your small intestine, this re-routing can reduce your chances to properly extract the vitamin from the foods in your diet, the Office of Dietary Supplements says. In turn, reduced extraction can lead to vitamin D deficiency. In addition, obese people who donБt undergo gastric bypass can hold abnormally high amounts of vitamin D in their fatty tissues. While this is not a problem of fat absorption, it can still result in lowered availability of the nutrient in other areas of your body. Consult your doctor for more information on problems related to vitamin D absorption and fat absorption.
Hmmmmmm.


Lots of things to think about. When I got home from Mayo, one of the doctors gave me a prescription and it was like off the charts for each pill. 20,000 IU's each or something crazy. And I took the prescription to my doctor that balances me out and they said it didn't muscle test well at all and I was really afraid to take it being such a large dose. When I would take the D3 and feel lousy, it was a very small amount. It was a cap that was 1000 IUs. Then I would sometimes break it open, just to see if I could do a little and even amounts like 1/4 would make me feel terrible. Very fatigued. I suppose it could have been doing good and I felt awful. I don't know. I just looked at the prescription of D that I got from the doctor at mayo. It was 50,000 IU's in each pill. I'm sorry, my body is too sensitive to do that and in light of how I can react to inputs, I thought it very unwise to even try. And they are gel caps, and I thought about poking a pin in them and getting a little. But even in that huge dose, I figured a plop on the tip of a needle might be way too much.


Now, I'll never know, but dang. Strangely, I take a mineral supplement and it has 600 IUS of D3 in it and I don't feel like it has affected me. But mind you, I never get 600 IU's because most of the time I've ground the multi up and taken about 1/16 of the pill. My body seems like it has been in a mode where I just don't want too many supplements any longer. I do eat very well, because it's been a huge focus. There's always room for improvement in that area too, but I do pretty darn good. I may need to do like policy checker said and just try and be in the sun more. I'm pretty sure it is all related to the fact that I don't absorb fats well and my gut needs to be balanced. I've been sincerely trying to do that with probiotics and cultured veggies, but it is a slow process. I think it's getting better, but sometimes I wonder. I do know this, overall I feel better than I did when all this junk started 4 years ago. Has any of you struggled with weight or digesting fats?
