Since vitamin D deficiency has been identified with a long list of health issues, including PCOS, I've been hearing readers, clients, colleagues, and friends talk about loading up on this nutrient with supplements. They're going about it in a not-so-scientific fashion, and I've wondered if that wasn't going to introduce a whole new spectrum of health issues.
A friend and colleague recently mentioned that she had just had a cholesterol test taken, and the LDL (bad cholesterol) reading had increased since her previous test. One of the changes she could identify was between the two tests, she had started to supplement with vitamin D.
I did a pretty thorough search both on the Internet and Pub Med to see if this was a common problem and didn't find anything. I then went to a listserve of about 1,000 nutrition colleagues to see if they'd seen it. Turns out, a few of them had also seen their cholesterols increase with vitamin D supplementation.
There is a tendency with nutrition, to adopt an"if a little is good, a whole lot is better" attitude. Unfortunately, imbalance in either direction, be it deficiency or excess, can be problematic.
The old recommendations for vitamin D were 200 IU per day. All of a sudden, a website popped up recommending 5000 IU per day. I couldn't find any research to support this magnificent dosage leap. I would have thought, given that magnitude, that some kind of dosing study that had ruled out that 500, 1500, 2000 IU were not sufficient. But no, the recommendations simply jumped without explanation.
And every time I tried to find out what the basis for this jump was, I kept being referred back to the website making the recommendation.
My points are:
1. Know your vitamin D and your cholesterol levels.
2. Start out with 200 IU or even 400 IU per day and see how that affects both your vitamin D levels and your cholesterol levels.
3. Consider that the reason vitamin D levels may be deficient is more complex than the simple fact that dietary vitamin D is low…did you know that many of the same health issues associated with vitamin D deficiency are also related to omega 3 fatty deficiency as well as omega 6 fatty acid excess? Most nutritional problems, if they are related to imbalance, cannot be corrected with a supplement. The overall balance of the diet needs to be considered in the plan of correction.
