Food additives and other forms of alternative medicines have been embraced
by the general public. Some of these compounds including glucosamine and ch
ondroitin sulfate have shown efficacy in relieving pain associated with ost

ability of these agents. More controlled studies and basic research is nece
ssary to evaluate these claims especially because these compounds are not u
nder regulatory control.
