My wife and I both take it.......mother in law with terrible arthritis takes it.

In mid-90's I asked a grizzled old small town vet if it was any good, since my MIL was thinking about taking it then.

His comment---------- he had been taking it for years, had been prescribing it for horses for years, and was taking the same stuff as he was giving the horses.........lots cheaper than the human stuff, said he.
