The Active Ingredient Is: Calcium (Calcium Carbonate and Calcium Citrate)

Calcium is a mineral essential for normal bone structure and function, including muscle and nerve activity and heart health.

This formula also includes Vitamin D3 to help calcium absorption, and contains no binders, fillers, gluten or casein, so it's suitable for sensitive individuals.

What Does Calcium Do?

Calcium is involved in maintaining bone density and normal muscle contraction and nerve signalling, in line with EFSA guidance on nutrient function. Dr. Weaver from University of Oxford found that calcium with vitamin D supplementation is linked to better bone mineral density and related benefits, supporting the role of these nutrients in bone health.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
