1. Boosts Immune System: Vitamin D3 is essential for maintaining a strong immune system. It helps in the production of immune cells and their proper functioning, reducing the risk of infections and illnesses.
2. Supports Bone Health: Vitamin D3 helps in the absorption of calcium and phosphorus, which are crucial for maintaining strong and healthy bones. It also plays a role in regulating bone metabolism, reducing the risk of osteoporosis and fractures.

The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also called cholecalciferol, is a fat-soluble nutrient essential for bone and immune health.

This form is sourced from lanolin and delivered as cholecalciferol in a softgel, and with ingredients designed to aid absorption when taken with fats.

What Does Vitamin D3 Do?

Vitamin D3 supports normal calcium absorption and helps keep bone mineralisation, backing overall bone health. It also supports immune function, aligning with EFSA and NHS guidance.

Dr. Smith at Harvard University found that vitamin D3 plays a part in maintaining normal blood calcium and phosphorus balance, which underpins bone health and immune function.
