The Active Ingredient Is: Calcium (Bisglycinate Chelate Form)

Calcium is a key mineral involved in bone mineralisation and supports muscle function, nerve signalling and cardiovascular health. This product offers calcium in bisglycinate chelate form for improved absorption. The formula also includes Vitamin D-3, which helps support calcium uptake in the gut and overall skeletal health.

What Does Calcium (Bisglycinate Chelate Form) Do?

Calcium participates in bone structure and normal muscle contraction and nerve function, with supporting EFSA-era guidance. Dr. Heaney of the University of Nebraska found that calcium bisglycinate chelate can offer superior absorption compared with some traditional calcium salts, supporting healthy bone maintenance. Vitamin D-3 further helps with intestinal calcium uptake.
