Search Results for "Vitamin D3"

Vitamin D3 is the sunlight vitamin your body turns into a hormone that helps you absorb calcium and keep bones strong. It also talks to immune and brain cells, which is why people look to it for fewer respiratory infections, better mood, and healthy aging. Think of it as a small regulator with big reach—most useful when your levels are low.

• Maintain strong bones and reduce fracture risk (especially when paired with calcium)
• Support immune defenses against respiratory infections
• Support mood in adults with depressive symptoms or low vitamin D
• Support healthy aging (lower risk of cancer death observed in trials)
