Product Information
Vitamin C plays an important role in immunity, energy production, normal collagen formation and function of cartilage. It also protects cells from oxidative stress, contributes to the reduction of tiredness and fatigue, making it a useful supplement as part of a regime.
Nutritionists often recommended supplemental vitamin C to cover any nutritional shortfalls. However, vitamin C is known to cause slight gastric upset in those with sensitive digestions.
Ester-C®, a unique patented form of vitamin C, is non acidic, meaning it’s an extremely gentle form of vitamin C. With a full 500mg of vitamin C, Ester-C® is a popular choice for those who experience tummy upsets when taking acidic forms of vitamin C.
We’ve chosen to provide Ester-C® in tablets instead of capsules to optimise absorption and ensure our formula is as gentle on the stomach as possible.
All of our vitamin C products are made in UK factories working to rigorous Good Manufacturing Practice (GMP) to meet our quality standards.
This product is suitable for both vegetarians and vegans.

Only one available at the price I can afford. I need to take higher dose of Vitamin C to aid the efficiency of a medical tablet. But I cannot take a normal Vitamin C because of silent acid reflux. This product has no after effects on my stomach. Brilliant!
