Vitamin D3 (cholecalciferol): a fat‑soluble vitamin made in skin from UVB exposure and found in some foods/supplements. Converted to active calcitriol, it regulates calcium and phosphate.
Benefits
Bone health: boosts calcium absorption and bone mineralization; reduces rickets, osteomalacia, osteoporosis risk.
Immune support: modulates innate and adaptive immunity.
Muscle function: supports normal strength and function.
Mood/cognition: low levels linked to depressive symptoms and cognitive decline; supplementation may help if deficient.
Cardiometabolic: some links to cardiovascular and metabolic health, but evidence is mixed.
