Rick, my osteopath ( Alice the Hun)recommended this to me.....with condroitin......in 500mg doses 3 times a day.....it is horribly expensive and I have to say doesn't appear to have helped much with my back problems but then I'm crap at adherence so it may be my fault.My understanding is that it can repair and strengthen muscle and cartiledge but it should also be able to restore your youth,increase your intelligence by a factor of ten and make the tea for what it costs.
