The Active Ingredient Is: Calcium (from calcium citrate)

Calcium is a mineral that participates in bone mineralisation and structural support in the body. This form uses calcium citrate, which is readily absorbed, helping to support overall calcium status. This formula also has included Vitamin D3, which supports calcium absorption and contributes to bone health alongside calcium.

What Does Calcium (from calcium citrate) Do?

Calcium participates in bone strength and normal muscle function, while Vitamin D3 enhances intestinal calcium absorption to support mineral utilisation. Research indicates that when calcium is paired with vitamin D, absorption and bone-related functions are optimised, reinforcing skeletal integrity under normal physiological conditions.

Dr. Weaver of the University of California found that combined calcium and vitamin D supplementation can influence bone density and fracture risk in adults, supporting the role of this nutrient combination in skeletal health.
