Kitchener Naturopath shares information regarding Vitamin D supplements

Vitamin D Matters

I recently read an article on over-the-counter and compounded Vitamin D potency that I feel is worth sharing.  You need to know that the Food and Drug Administration does not regulate vitamin D supplements, so potency may not be well evaluated.

In a recent trial examining Vitamin D in menopausal women, it was found that supplement potencies varied.  Researchers tested 55 bottles of over-the-counter Vitamin D from 12 manufacturers.  Results showed that the over-the-counter pills contained 52% to 135% of the expected dose instead of the required 90%-120% for solutions.  When averaged over 5 pills, 1/3 did not meet standards.

The take-away message here is that it pays to purchase quality supplements.  I’d be happy to answer any questions you may have and/or provide you with a good product.
