What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium absorption and supports immune system function in line with NHS and EFSA recommendations.

Dr. Martineau of University of Oxford found that vitamin D supplementation can modulate immune responses, contributing to a balanced immune defence.
