Active Voice: Does Vitamin D Have a Role in Preventing Sarcopenia?

from By Caitlin Mason, Ph.D.

Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily reflect positions or policies of ACSM.

Dr. Mason is a postdoctoral research fellow at the Fred Hutchinson Cancer Research Center in Seattle, WA. With a background in epidemiology, her research focuses primarily on understanding the mechanisms that link nutrition, exercise, and body composition to chronic disease risk, including cancer.

This commentary presents Dr. Mason’s views associated with a research article she and her colleagues published in the April, 2013 issue of ACSM's
Medicine and Science in Sports and Exercise® (MSSE).
