  • Vitamin C with almost 100% concentration (>99%)

How are we different?

Our high-dose zinc as organic zinc bisglycinate. The zinc is bound here as a zinc chelate to the amino acid glycine.

Since no natural source of L-glycine exists yet, we use an ultra pure, synthetic zinc bisglycinate that is produced in Germany. Our zinc bisglycinate is not derived from animal or human hair and is therefore also suitable for vegetarians and vegans.

Each capsule also contains 125mg of our premium vitamin C, obtained via a complex manufacturing process. High-dose vitamin C is obtained almost exclusively from corn, the quality of which can vary. It is therefore important to us to ensure that the raw material is sourced exclusively from non-GMO corn. This raw material, through our multi-stage manufacturing process conducted according to the highest quality standards, is transformed into our ultra-pure vitamin C—and contains no trace of corn, fructose or any chemical solvent residues (although common practice, we do not use methanol as a solvent). The result is our highest concentrated vitamin C, with a purity level of over 99%.

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 jars.
