Diet, sex, and age as determinants of muscle carnosine concentration in healthy humans
This study asks a simple question with practical consequences: who is walking around with less carnosine in their muscle to begin with? It compared diet patterns, sex and age in healthy people.
Key takeaway
Vegetarians and women carry noticeably lower muscle carnosine than meat-eating men, and levels fall steadily with age — which explains why some people notice a change and others do not.
