Vit. D Potency Varies widely from label claims-JAMA Internal Medicine Feb 2013:
Erin LeBlanc from Oregon Health & Science University and colleagues reported that Vit. D supplement brands varied widely from label claims. 12 manufacturers were checked and contents ranged from 52 to 135% of expected dose.
Points from me…A good source of vitamin D may be hard to find.
Our bodies manufacture vitamin D3 when skin is exposed to the sun s ultraviolet-B rays which can be blocked by both windows and sunscreen.
And vitamin D is found naturally only in a few foods (e.g., fish, eggs).
That’s why products like milk are vitamin D-fortified.
Dietary supplements are often recommended, but vary in quality and may not include D3, which may be 3 times more potent than D2.
The supplement form (e.g., liquid, tablet) and manufacturing may also influence absorption potential.
That’s why it s just as important with this “basic” vitamin to seek higher quality for maximum benefits.
