I bought on the recommendation of my physiotherapist this powder because I have problems with my knees. Incipient osteoarthritis leads to grinding and rubbing in the Gelänken to severe pain. This extract is to improve metabolism in the knee and provide better "goo". I try it out. My advice, however: order better capsules, because the powder tastes unbelievably bad. I fill it to me now in empty capsules, so I can take it at all, without disgust me.
