Vitamin D for Muscle and Balance?

Why did a recent study show that both high and low-dose vitamin D didn’t improve muscle strength or balance in women despite the fact that other studies have shown vitamin D to help? The likely answer has to do with the vitamin D status (i.e., blood levels) of the people chosen to participate in these studies. To find out what you should do to improve your balance and reduce your chance of falling, see the "Muscle, Balance and Falls" section of the Vitamin D Supplements Review >>

It turns out that one may, and one may not. Find out more and get our quality ratings of cholesterol-lowering supplements in the updated Cholesterol-Lowering Supplements Review >>

Vitamin D Increases Strength

A recently published review of clinical studies found that supplementing with vitamin D can improve muscle strength in young, healthy men and women.
