Muscling In On Vitamin D

Muscling In On Vitamin D Vitamin D's importance centers around its role in controlling calcium and phosphate levels. Of course, like most vitamins and minerals, vitamin D is involved in numerous other functions. A study published in the journal Medicine and Science in Sports and Exercise suggests muscular strength might be one of them.

Researchers used a serum 25-hydroxy vitamin D test to determine the total amount of vitamin D in 419 healthy men and women between the ages of 20 and 76. Then these subjects performed a series of upper and lower body isometric and isokinetic strength tests. After analyzing results, it was determined that vitamin D levels are directly related to both isometric and isokinetic arm strength, but only to isometric strength in the legs.

True Strength Moment: Many foods are fortified with vitamin D and it can also be synthesized through exposure to sunlight. Unfortunately, those living in northern regions might not be able to get an adequate supply during the winter months. That's one reason many active adults rely on high-potency multivitamins as nutritional insurance.
