The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also known as cholecalciferol, is a fat-soluble nutrient essential for the intestinal absorption of calcium and phosphorus. This form is derived from fish liver oil and provided in an oil-based preparation to support bioavailability.

This product uses vitamin D3 in a cholecalciferol form to support normal mineral balance and skeletal structure, with sourcing prioritising high-quality, ethically sourced materials.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate the body's calcium and phosphorus levels, which supports normal bone and teeth health and aligns with EFSA and NHS guidance. It also participates in immune function and broader physiological processes as part of everyday health maintenance.

Dr. Holick of Harvard University found that vitamin D3 is essential for calcium absorption and bone maintenance, reflecting its role in supporting skeletal health.
