Beta-Alanine May Increase Carnosine Levels, Reduce Fatigue

Carnosine is a combination of two amino acids, alanine and histidine, and has been shown to help prevent cellular damage from free radicals. A recent study suggests that taking a daily supplement of beta-alanine may increase the carnosine content of muscles and reduce fatigue during exercise in both men and women.


Participants in the study included 26 men and women who were given either six grams of beta-alanine or a placebo daily for four weeks. All of the participants underwent intensive exercise at the beginning and end of the study.


At the conclusion of the study, the researchers noted increased muscle carosine levels in the beta-alanine group, when compared with the placebo. There were no differences between the men and the women. Additionally, the beta-alanine group had less muscle fatigue during exercise, when compared with the placebo.


Researchers from the University of Central Florida conducted the study. It was published online ahead of print on October 7, 2017, in Nutrition Research.


Beta-alanine is an amino acid that previous studies have found may help build lean muscle mass, improve physical function in general, and improve physical function in the elderly. It can primarily be found in meats but the most effective way to consume beta-alanine is in a supplement form.
