Vitamin D3 is naturally produced by the body when the skin is exposed to ultraviolet radiation. Modern lifestyles and the use of sunscreens often result in vitamin D3 deficiency, which is why it needs to be supplemented with dietary supplements.

Vitamin D3 contributes to:

• the normal absorption and utilization of calcium and phosphorus
• the maintenance of normal blood calcium levels
• the maintenance of normal teeth, bones, and muscle function
• the normal function of the immune system
• the process of cell division

Vitamin D3 in dietary supplements usually comes from animal sources and is therefore unsuitable for those following a vegetarian diet.

Vitamin D3 in the Immuvit Vitamin D3 (cholecalciferol) dietary supplement is 100% plant-based.
