Premium Bioactive Ingredients

  • Pure plant extract from birch bark (Betula platyphylla)
  • With 98% betulin
  • Betulin is a triterpene that gives birch bark its characteristic white color
  • High purity extraction using only water and ethanol, with no solvents
  • Acacia fibre-rich in dietary fibre as a natural filler
  • Vegan, non-GMO, no additives
  • Premium HPMC capsule shells: 100% free from carrageenans and PEG

How are we different?

Our betulin is obtained as a pure, natural water/ethanol extract from birch bark (Betula platyphylla). No other solvents such as methanol or acetone are used; due to the gentle extraction process, the natural spectrum of ingredients is largely preserved. The result is a highly pure extract with 98%+ betulin.

The only other ingredient we use as natural, fibre-rich filler is premium acacia fibre grown without pesticides, instead of the typical, synthetic filler, microcrystalline cellulose, which is mixed with nano-particles. Our acacia fibre comes from climate-neutral, sustainable resource-conserving and fair cultivation.

For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC capsules that can be found 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.
