How are we different?
Our vegan raw material is produced via fermentation from non-GMO maize. Purely plant-based raw materials serve as the sole nutritional source for the non-GMO microorganisms involved in the fermentation process. Production avoids all animal-derived ingredients—such as gelatine, hair or feathers—relying exclusively on plant-based, renewable sources.
This elaborate manufacturing process yields a pure raw material of the highest quality, with a purity level exceeding 98.5% and remaining entirely free from additives.
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 use environmentally friendly amber glass for the packaging of this product.
