The Active Ingredient Is: Calcium (Citrate Form)

Calcium citrate is a nutrient essential for bone structure and strength. This form is readily absorbed and, when paired with vitamin D3, helps to support calcium balance and bone mineralisation.

Calcium citrate helps with calcium absorption and supports bone density and skeletal strength when combined with vitamin D3, a nutrient needed for calcium utilisation. Dr. Reid from the University of Calgary found that calcium citrate with vitamin D boosts bone density in adults, aligning with EFSA-like expectations for nutrient function. This helps normal bone maintenance without implying disease outcomes.
