The Active Ingredient Is: Calcium (Hydroxyapatite)

Calcium is a mineral that makes up part of the bone structure and helps support normal skeletal function.

This form uses hydroxyapatite sourced from freeze-dried New Zealand veal bone, delivering calcium and phosphorus in a natural 2:1 ratio along with other organic bone constituents.

What Does Calcium Do?

Calcium participates in maintaining normal bone mineralisation and supports natural bodily functions as recognised by EFSA; it helps nourish bone structure and density to support overall skeletal health.

This formula also includes a broad spectrum of micronutrients that assist calcium utilisation and maintain bone balance, contributing to the connected support of bone health.
