What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium absorption for bone health and supports immune cell activity, in line with NHS and EFSA guidance.

Dr. Holick of Harvard University found that Vitamin D3 is converted in the body to an active form that modulates calcium handling and immune function, contributing to overall wellness at the cellular level.
