Vi­ta­min D de­fi­ciency is widely over­es­ti­mated, doc­tors warn

Daily Freeman (Kingston, NY) - - NATION+WORLD -

Doc­tors are warn­ing about vi­ta­min D again, and it’s not the “we need more” news you might ex­pect. In­stead, they say there’s too much need­less test­ing and too many peo­ple tak­ing too many pills for a prob­lem that few peo­ple truly have.

The nu­tri­ent is cru­cial for strong bones and may play a role in other health con­di­tions, though that is far less cer­tain.

Misun­der­stand­ings about the rec­om­mended amount of vi­ta­min D have led to mis­in­ter­pre­ta­tion of blood tests and many peo­ple think­ing they need more than they re­ally do, some ex­perts who helped set the lev­els write in to­day’s New Eng­land Jour­nal of Medicine.

Cor­rectly in­ter­preted, less than 6 per­cent of Amer­i­cans ages 1 to 70 are de­fi­cient and only 13 per­cent are in dan­ger of not get­ting enough.

That’s con­cern­ing, “but th­ese lev­els of de­fi­ciency do not con­sti­tute a pan­demic,” the au­thors write.

Yet peo­ple may think there is one.
