The Claim
Beta-alanine supplementation at 6.4 g/day for 4 weeks increases intramuscular carnosine levels in highly-trained judo athletes.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking 6.4 grams of beta-alanine daily for four weeks raises the amount of carnosine in the muscles of highly-trained judo athletes.
See the scientific wording
Beta-alanine supplementation at 6.4 g/day for 4 weeks increases intramuscular carnosine levels in highly-trained judo athletes, which is the established biochemical mechanism underlying its effects, though direct muscle carnosine measurements were not performed in this study.
Beta-alanine enters muscle cells and combines with another molecule to make carnosine. Carnosine catches acid particles produced when muscles work hard, which lets the muscles keep working longer without getting tired from burning sensation.
What the research says
1 studyStudy: Beta-alanine supplementation enhances judo-related performance in highly-trained athletes.
This study showed that judo athletes who took beta-alanine could do more throws during intense training than those who took a sugar pill. Since beta-alanine is known to boost a muscle compound called carnosine that helps fight muscle burn, and these athletes performed better without changes in blood acidity, it strongly suggests carnosine went up — even if they didn’t measure it directly.
