The Active Ingredient Is: Calcium (StimuCal MCHA)

Calcium is a key mineral that sits in bones and teeth, helping their structure and density as part of everyday body function.

This version uses calcium from StimuCal microcrystalline hydroxyapatite pulled from bone proteins and delivered for bone health in a natural, bioavailable way.

What Does Calcium Do?

Calcium helps keep bone mineral density up, contributing to the normal function of the skeleton overall. Vitamin D3 and Vitamin K2 in the blend help calcium deposit into bones, helping with the utilisation of calcium for bone health.

By giving calcium alongside these vitamins, the formula aims to support normal bone maintenance and mineral balance.
