The surge in popularity of vitamin D has largely been prompted by the growing number of doctors recommending patients get their D level checked, and then prescribing supplementation if their level is under 30 ng/mL. In response, the Food and Nutritional Board (FNB) was commissioned to review the current body of vitamin D research. Results were available last week.
The once under-promoted “sunshine vitamin” has been thrust into the spotlight in the last few years, prompting the need for further studies to establish more precise dosing guidelines.
Critics of the revised RDA for vitamin D say the numbers don’t come close to the required amount people need to assist in the prevention of a long list of health conditions associated with a D deficiency.
Cannell feels the FNB is publicizing misinformation and that the panel’s messaging will make people unnecessarily fearful of overdosing, something he says is extremely rare, particularly with cholecalciferol, referred to as D3. D3 is the naturally occurring form of vitamin D that is made in large quantities when sunlight strikes bare skin; it can also be taken as a supplement.
