My husband and father-in-law both drink this. They both suffer from joint stiffness and pain. This really works for them. I can tell when my husband forgets to drink it in the way he walks. Takes a few days to really see the effects but great product.
Husband and father both use this. My dad doesn't like the taste and drinks it as quickly as possible. My husband doesn't mind it, which means that it really could be better. Works well for lubing the joints though. Hubby definitely feels better on the days that he drinks one.
