From what I understand is that it is a drink (or powder) that helps aid in rebuilding cartilage. The big difference between Supple and other glucosamine and chondritin products is that supple uses top quality ingredients. They claim that since it's unregulated, many companies use low grade stuff and they apparently do not. There's a good site that addresses a lot of questions: www.truthaboutsupple.com Hope this helps.
