The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, or cholecalciferol, is a fat-soluble nutrient essential for normal bone and immune system function. This form is commonly sourced for dietary supplements and supports the body’s utilisation of calcium and phosphate to maintain healthy skeletal structure.

In this formulation, vitamin D3 is provided in a bioavailable form suitable for daily use, complementing vitamin K1 to support overall mineral metabolism.

What Does Vitamin D3 Do?

Vitamin D3 assists with calcium absorption and helps regulate mineral metabolism, supporting broad physiological functions including bone health and immune response. NHS and EFSA guidance emphasise its role in maintaining normal bone structure and immune function, respectively, when taken with dietary fats for optimal absorption.

Dr. Holick of Harvard University found that daily vitamin D3 supports bone health and immune function in adults, aligning with recognised nutritional guidelines.
