Hello, Black-widdow,
I think it is a product based on simple gelatine. As gelatine has much proteine and is good for articular capsules. Gelatine products you can buy at good price in drugstore. I think purchasing Gelastin-Gelenk-Protein you only pay for the name and advertising. Choose gelatine casules (no name product) of high dosis, they will have same effect and are much more cheaper.
All the best for you Agnese
