Increase skeletal muscle mass

What this outcome means

Skeletal muscle mass is the amount of muscle tissue your body carries, which underpins strength, movement, and a healthy metabolism. On DoseRank it maps to a defined health outcome built from human studies on lean body mass, cross-sectional muscle area, and total muscle volume – data sourced from open sources and specialized resources. DoseRank is not medical advice.

Who it's for

Age-related lossOlder adults working to hold onto muscle over time.
