The Claim
Beta-alanine supplementation attenuates neuromuscular fatigue in older adults, resulting in up to a 37% improvement in physical working capacity at fatigue threshold after 90 days of supplementation.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking beta-alanine for 90 days increases physical working capacity at the point of fatigue by up to 37% in older adults.
See the scientific wording
Beta-alanine supplementation attenuates neuromuscular fatigue in older adults, with studies showing up to a 37% improvement in physical working capacity at fatigue threshold after 90 days of supplementation.
Beta-alanine enters muscle cells and combines with another amino acid to form carnosine, which soaks up excess acid produced during hard exercise. This keeps the muscle environment less acidic, allowing muscles to keep contracting forcefully for longer before tiring.

Taking beta-alanine for a few weeks helps older adults stay stronger longer during exercise, delaying muscle fatigue by up to 37%, just like the claim says.
