Arthritis sufferers are routinely targeted by the $20 billion supplement industry, which has introduced more than 800 purported remedies for arthritis in recent years.
With so many different products promising relief, it’s tough to know which are worth trying. This month, American Family Physician, a medical journal, offers some guidance. A new review article sifts through the research to determine which supplements really work.
The review article’s top pick — glucosamine sulfate — is typically derived from crustacean shells. Unlike many products sold by the supplement industry, this one has been widely studied. According to the authors, researchers at Creighton University in Omaha, glucosamine has been the subject of more than 20 randomized controlled trials involving over 2,500 patients.
The findings have been inconsistent, however, likely because of varying formulations and study methods. The research does show that the type of glucosamine matters. Studies using a product called Dona consistently showed benefits for arthritis sufferers, the authors note, while glucosamine hydrochloride formulations have not performed as well.
“The evidence supports the use of glucosamine sulfate for modestly reducing osteoarthritis symptoms and possibly slowing disease progression,'’ the authors write. “However, there isn’t enough evidence to recommend the use of other glucosamine formulations.'’
