The Active Ingredient Is: Calcium (Calcium Citrate)

Calcium is a mineral that’s essential for normal bone structure and function, and for signalling in the body. This form uses calcium citrate for better absorption, and a citrate-based profile helps compatibility with other minerals.

Calcium citrate is a highly bioavailable source of calcium that helps balance minerals and is commonly used in bone health formulations.

What Does Calcium Do?

Calcium helps maintain bone structure and supports normal nerve signalling and muscle contraction, in line with EFSA guidance on nutrient function.

Additionally, the citrate form is linked to better absorption than some other calcium forms, contributing to calcium availability for normal bodily processes.
