Our silver fir extract is obtained by pure water extraction. For this, the branches of the silver fir are crushed, dried, macerated and then filtered. The extracted liquid is concentrated at 60°C under vacuum. Following a careful spray-drying process, a pure extract with a standardised high polyphenol content of 66% is obtained.
In contrast to customary synthetic fillers like microcrystalline cellulose, which is mixed with nano-particles, we use only natural, fibre-rich acacia fibre as a natural filler. Our acacia fibre is sustainably sourced from climate-neutral, resource-conserving and fair cultivation.
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.
