Col­la­gen sup­ple­ments

Runner's World (UK) - - Warm ups/ mind-health -

WHAT IS IT? Col­la­gen is a struc­tural pro­tein that’s rich in amino acids; it’s found in con­nec­tive tis­sue. Sup­ple­ments claim to pre­vent or ease joint pain and in­flam­ma­tion, and ac­cel­er­ate heal­ing.

DO THEY WORK? One study found that 13 weeks of sup­ple­men­ta­tion im­proved os­teoarthri­tis symp­toms – but it was con­ducted by a sup­ple­ment man­u­fac­turer. ‘There is no per­sua­sive ev­i­dence that col­la­gen can ben­e­fit arthritis or re­duce symp­toms such as joint pain,’ says Anita Bean, au­thor of Sports Sup­ple­ments (Blooms­bury). And a 2011 Euro­pean Food Safety Author­ity re­view found that a re­la­tion­ship be­tween col­la­gen sup­ple­men­ta­tion and joint health has not been sub­stan­ti­ated.

ARE THEY SAFE? No se­ri­ous ad­verse ef­fects re­ported. THE VER­DICT A pricey pro­tein source that’s un­likely to ease your joints.
