Vitamin D For Muscle Mass?

You see vitamin D fortification mentioned on the labels of milk, breakfast cereal and other everyday foods for a very good reason. Vitamin D is a crucial component of overall health. Its value as a micronutrient extends well beyond supporting calcium metabolism for strong bones. In fact, research published in the Scandinavian Journal of Medicine & Science in Sports suggests the 'sunshine vitamin' plays a role in protein synthesis.

The USC study found that adequate levels of vitamin D were important for building muscle size and strength. What happens when you don't get enough? Researchers found that women with lower than recommended vitamin D intake had higher levels of muscle fat than women who got enough.

True Strength Moment: Although Vitamin D can be synthesized through sunlight exposure to the skin, the sun screen you use to protect yourself screens out good and bad UV wavelengths. During winter months, people living in the northern latitudes typically don't have the opportunity to get vitamin D through sunshine anyway. This is where nutritional insurance in the form of a high-potency multivitamin can come in handy.
