The Active Ingredient Is: Calcium ascorbate

Calcium ascorbate is a buffered compound combining vitamin C with calcium, providing a gentle, tummy-friendly source of vitamin C with a modest calcium contribution.

This form is a pure buffered powder, where ascorbic acid is paired with calcium carbonate to neutralise acidity and improve gastrointestinal tolerance.

What Does Calcium ascorbate Do?

Vitamin C participates in collagen formation and acts as an antioxidant to protect cells from oxidative stress, while supporting normal immune function in line with EFSA guidance. Calcium provides a role in normal bone and neuromuscular function as part of a balanced intake.

Scientific research suggests vitamin C supports immune function and collagen synthesis, with buffered calcium ascorbate delivering these nutrients in a gentle, stomach-friendly form.
