Increase lean body mass

What this outcome means

Lean body mass is everything in your body that isn't fat — muscle, bone, organs, and water — and it's a key marker of preserved strength and metabolic health. On DoseRank it maps to a defined health outcome built from human studies on fat-free mass, skeletal muscle measured by DXA, and body-composition ratios – data sourced from open sources and specialized resources. DoseRank is not medical advice.
