This essential ingredient is: Vitamin D3 (Cholecalciferol)

Vitamin D3 is a fat soluble vitamin involved in key physiological processes, including helping with normal testosterone synthesis and bone and immune health.

This form is known as cholecalciferol and is widely recognised for its bioavailability and part in maintaining normal bodily functions.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium absorption, which supports healthy bones, and it also helps immune system function in line with NHS and EFSA guidance.

Dr. Johanning from the University found that Vitamin D3 supplementation can increase testosterone in deficient men, reflecting its role in hormonal balance.
