Beta-alanine is the rate-limiting substrate in the production of intramuscular carnosine, and its supplementation is responsible for directly increasing levels of carnosine in skeletal muscle. As a dietary supplement, beta-alanine has a range of applications, including serving as a cellular buffer, and increasing the capacity of skeletal muscles for work. Trials in humans have demonstrated that beta-alanine supplementation is directly linked to an increase in muscular strength in acute challenges, increased muscular performance, and a decrease in muscular fatigue.
Decrease muscular fatigue and increase muscle strength
Overall increase in muscle performance
Increase aerobic and anaerobic endurance
