Vitamin D, a key milk nutrient, linked to better muscle power

New study reveals teen girls with higher vitamin D levels may have improved muscle performance


2009-02-05

From the EurekAlert news item:

Young female athletes could have yet another reason to grab a glass of vitamin D-rich milk. Not only does vitamin D work with calcium to keep bones strong, but researchers now found that teenage girls with higher vitamin D levels may be able to jump higher and faster than their peers with lower levels, according to a new study published in the Journal of Clinical Endocrinology and Metabolism.

UK researchers collected vitamin D levels for 99 girls, ages 12 to 14. To test the girls' muscle function, the girls were instructed to jump as high as possible while researchers used a device designed to measure power and performance called jumping mechanography. After controlling for differences in the girls' body weight, the girls with the highest vitamin D levels had the highest jump speeds, jump height, power and force.

This potential muscle advantage adds to the growing list of evidence positioning vitamin D as a super nutrient. Well known for its role in keeping bones strong, vitamin D is now being hailed for so much more. Emerging science suggests vitamin D may also help protect against diabetes, hypertension, heart disease, and certain cancers. It may also support a healthy immune system to ward off infections, and some preliminary evidence suggests it may affect longevity.
