Thanks to a reader, Ron, who referred me to an abstract showing that vegetarians had lower muscle levels of carnosine, I have updated the VeganHealth page on carnosine and beta-alanine to suggest that vegetarians may very well be able to improve their athletic performance by supplementing with beta-alanine.

Someone asked me about carnosine a few months ago. I didn’t know much about it at the time, so I looked into it and here are the results:

Quick summary: No need to worry about it unless you are a serious athlete interested in experimenting with supplements that haven’t been tested long-term.
