Vitamin D3 — 2,000 IU

Vitamin D3 (cholecalciferol) at 2,000 IU per softgel — a daily maintenance dose for bone, muscle, and immune health.

Vitamin D supports calcium and phosphate metabolism, immune function, and bone, muscle, and overall skeletal health. Suboptimal vitamin D status is widespread, particularly in athletes who train indoors, live at northern latitudes, or have darker skin pigmentation. Low serum 25(OH)D is associated with impaired muscle function, increased injury risk, and compromised immunity.
