Vitamin D, as many of my regular readers know, is one of my favorite supplements. Research keeps on coming on all the good results scientists keep coming up with. Here is a small list from recently published articles:
- Vitamin D and cognitive function in the elderly.
- Vitamin D and the benefits to people with early inflammatory polyarthritis.
- Vitamin D and helping to lower the risk of fractures from falls.
- Low vitamin D and metabolic syndrome.
Still, there are times when you can get too much of a good thing. In the July 19th 2007 issue of the New England Journal of Medicine, a letter to the editor pointed out a case where a women developed a series of life threatening toxic effects from taking Solutions IE Ageless Formula II supplement from Aloe International which contained 186,906 IUs of vitamin D. The symptoms she suffered included nausea, fatigue, constipation, back pain, forgetfulness and vomiting. It is known that long-term daily vitamin D consumption of 40,000 IUs of vitamin D3 can cause hypercalcemia in health patients so the amount this women took was obscenely high.
Of course, this is an isolated instance and not the standard in the nutritional supplement business. This is an example though of why the industry needs to make sure it regularly checks each batch for quality. This is not being done unfortunately and the FDA was forced to step in and create a rule that the manufacturers of nutritional supplements must test their products. Some advocacy groups bristled at the thought of FDA control and rolled out the dreaded term CODEX to scare the public but sad to say, it was a necessary evil to bring some sanity to the nutritional supplement industry. I have personally seen products, like an electrolyte product on the market claiming 136 mgs of magnesium in each serving but when I checked out their label claim through an independent lab, they only had 32 mgs of magnesium. That is only one-third of the label claim. This same company has already been admonished twice by the FDA for other offenses (like selling a product that could cause miscarriages) yet they stay in business.
There are many good companies out there but consumers must be wary. Hopefully, the new regulations will mean better and safer products on the market.
