The use of top-quality raw materials is a must for Biogena. We would never be able to manufacture high quality products from raw material of mediocre or dubious quality. We choose the ingredients exclusively according to criteria of quality and purity, sustainability and scientific documentation. We source our ingredients from certified suppliers from all over the world and they are available in top bioavailable compounds. Biogena preparations that contain branded raw materials normally carry the logo of the branded raw materials on their label. This is a benefit for our customers since they can get additional information concerning the materials’ quality and manufacture. Customers can potentially read studies concerning the raw material on the manufacturer’s website.
