How are we different?

We use plant-based L-methionine derived from the fermentation of (non-GMO) corn starch. In the production process we do not use any animal products, such as gelatine, hair, or feathers. We use only plant-based, renewable raw materials. Although the synthetic production of amino acids is harshly criticised by environmental organisations due to the water pollution it causes, the production of natural amino acids does not cause any environmental pollution. Our vegan L-methionine has a purity of 98.5% - without any additives and free from residues from chemical synthesis, such as 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.
