How are we different?
Our vegan amino acid 5-HTP (5-hydroxy-L-tryptophan) is derived via pure food-grade water-ethanol extraction of the African black bean (Griffonia simplicifolia). No other solvents, such as acetone or N-hexane, are used during the extraction process, so this seed extract contains absolutely no residues. After gentle spray drying, the fine powder is standardised to a 5-HTP content of at least 30%. The non-GMO manufacturing process results in a very pure raw material of the highest quality.
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.
