How are we different?
Our compact functional blend of 6 carefully selected ingredients supports the nervous system (B2, B6), psychological function (B6) and the protection of cells from oxidative stress (B2). It combines valuable botanical extracts from ashwagandha and Rhodiola rosea with B-vitamins and the amino acid L-glycine.
We place special emphasis on the high quality of the ingredients used: the premium KSM-66® ashwagandha root extract from India contains the highest naturally achievable withanolide content (5%) from a pure root extract. It delivers the full spectrum of withanolides from the root in their natural ratio. For our product, the usual milk pre-treatment of the ashwagandha roots is omitted during production, making the extract perfectly suitable for vegans. The rhodiola extract comes from wild-harvesting in the powerful nature of the primeval Altai Mountains in Siberia. Due to this nourishing, natural environment, the rhodiola is particularly rich in valuable phytochemicals. In contrast to many extracts imported from Asia, our rhodiola extract is extracted exclusively with food-grade ethanol and at no point comes into contact with controversial solvents such as acetone or n-hexane.
The functional blend is completed with the amino acid L-glycine of the highest quality and purity, as well as with the bioactive B-vitamins B2 as riboflavin-5-phosphate, B5 as pantothenate and B6 as pyridoxal-5-phosphate P5P.
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 jars for the packaging of this product.
