The Active Ingredient Is: Vitamin C (Calcium L-ascorbate Ester-C)

Vitamin C, in the Ester-C form as calcium L-ascorbate, is a water-soluble nutrient essential for normal connective tissue health and immune function. This non-acidic, buffered form is designed to minimise gastrointestinal discomfort while delivering antioxidant support alongside plant-derived bioflavonoids.

This formulation combines Ester-C calcium L-ascorbate with a Citrus bioflavonoid complex, rutin and Pycnogenol®, which together help stabilise capillaries and support antioxidant activity and recycling of vitamin C.

What Does Vitamin C Do?

Vitamin C participates in normal collagen synthesis and supports capillary strength, connective tissue structure and immune system function. The accompanying bioflavonoids contribute to antioxidant protection and may enhance vitamin C absorption and recycling. The NHS and EFSA recognise vitamin C as supporting these normal physiological functions.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
