Certificates and awards
Our gummies include a high-quality Lion’s Mane fruiting-body extract, chosen for its concentration of naturally occurring beta-glucans and active compounds. Every extract batch is verified in an independent German laboratory to confirm purity and consistency before it ever reaches our formulation. By incorporating a meaningful amount of Lion’s Mane into each serving (700mg), we bring one of nature’s most researched functional mushrooms into your daily routine: clean, tested, and expertly crafted.
High-quality Cordyceps sinensis extract, valued for its naturally occurring cordycepin and polysaccharides. Sourced from controlled fermentation rather than wild harvesting, it offers consistency, purity, and a significantly lower environmental impact. Each batch is independently tested to verify identity and screen for impurities, ensuring a clean and reliable extract every time. By incorporating a meaningful amount of Cordyceps into our formulation, we bring one of the most studied functional fungi into your daily routine—steady, potent, and professionally crafted.
Our formulation features a carefully sourced Chaga fruiting-body extract, valued for its exceptionally high antioxidant content and naturally occurring beta-glucans. Every batch undergoes independent laboratory testing in Germany to confirm quality, purity, and consistency before it enters production. Delivered at a functional 700mg per serving, Chaga brings long-term, everyday support — not quick fixes — into your routine.
We use a premium Reishi fruiting-body extract, chosen for its concentration of beta-glucans and bioactive compounds traditionally associated with balance and resilience. As with all our extracts, each batch is independently verified by a German laboratory to ensure purity and consistency before formulation.

KSM-66 Ashwagandha, one of the most clinically researched Ashwagandha extracts available and renowned for its high concentration of root-only withanolides.

By including a meaningful amount of KSM-66 in our formulation, we bring a globally respected botanical into your daily routine with precision and integrity.
Plant-based source of Omega-3 DHA and EPA, derived directly from sustainably cultivated algae rather than fish.

Each batch of algae oil is rigorously tested for purity, stability, and oxidation markers to ensure clean, consistent quality. By incorporating a meaningful amount of DHA and EPA into our formulation, we bring a highly bioavailable, vegan-friendly Omega-3 source into your daily routine - cleaner for you, and cleaner for the planet.
ur gummies also include a thoughtfully balanced blend of essential vitamins and minerals: Vitamin B5, Vitamin B6, Vitamin B12, Zinc, and Vitamin D3.
