Biogena capsules are not designed for opening and directly swallowing the active ingredient powder they contain. If possible, you should – as intended – swallow the capsule as a whole. In exceptional cases, such as, for example, if you have trouble swallowing the capsule, our powder preparations can be opened by pulling the two halves of the capsule apart. The active ingredient powder can be stirred into water, still mineral water or herbal tea and should be consumed immediately. Since black tea, coke or fruit juices can inhibit the absorption of the active ingredient in the body, they are not suitable for mixing. It is not possible to open the capsule for all Biogena products, however. No enzyme preparations should be opened (DigestioCym 200 vegetarisch, BromeZym Zink 10, ConfiZym and DoloZym forte Gold, LactroZym and DAOZym), nor probiotics (Omni Lactis 20 Gold and Omni Lactis 20 Pur Gold). In the case of iron (Ferrogena 10, QuattroFerrin 21, SmartFerrin B12, MoFerrin 21, Iron & Vitamin C), opening is also not recommended since it can cause the teeth to be stained.
