The Active Ingredient Is: Vitamin C (Ascorbic Acid)
Vitamin C, also called ascorbic acid, is a water-soluble nutrient essential for everyday bodily functions. The product uses a buffered form of ascorbates to reduce stomach acidity and make it gentler on the stomach.
This blend combines sodium, potassium and magnesium ascorbates with ascorbic acid to support smooth delivery and high bioavailability.
What Does Vitamin C Do?
Vitamin C plays a part in normal immune system function and acts as an antioxidant to help shield cells from oxidative stress. It also helps with collagen formation, in line with EFSA guidance on nutrient function.
The buffered formula helps minimise stomach upset while delivering high-potency vitamin C for normal bodily roles.
