What Does Vitamin D3 Do?

Vitamin D3 helps maintain normal bone mineral density and backs immune function, with research suggesting it can help keep serum levels in the optimal range when paired with a balanced diet. Studies show that this kind of supplementation links to steady bone health and immune support in adults.

Dr. Manson from Harvard University found that vitamin D3 supplementation raises serum levels and keeps them within the normal range, shaping UK NHS/EFSA-aligned understanding of its role in the body.
