How are we different?
Our Vitamin C Pure is derived from an intesive manufacturing process. Vitamin C is obtained from the raw material sorbitol through a specialised, multi-stage fermentation process, adhering to the highest quality standards. The end result is our highest concentration of vitamin C with over 99% purity, completely free from fructose and residues of chemical solvents.
For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG. We then package this product in environmentally friendly amber glass.

Effects
Vitamin C is involved in numerous redox reactions as an antioxidant and cofactor, thus influencing numerous processes in the human body, such as energy metabolism and the immune system, and providing antioxidative protection to cells. It is also involved in the formation of collagen, the structural protein found in skin, cartilage, bones and blood vessels, as well as in the synthesis of hormones.
High concentrations of vitamin C are found naturally in fresh fruits, vegetables and berries such as camu camu, sea buckthorn berry, acerola cherry, rosehip, black currant, kale, parsley, kiwis and citrus fruits, among others.
