There is a good reason caffeine and beta-alanine are the two most popular ingredients found in preworkout supplements. There is plenty of research on both ingredients, and the research is overwhelmingly positive on their ability to improve workout performance. The same is not true for tyrosine. Verdict: caffeine and beta-alanine...
Theoretically, beta-alanine should improve performance in several activities, especially high intensity or longer duration ones. Let's take a look at what the research says!
During exercise, increased pH can cause fatigue and hamper performance. Resistance training relies on the anaerobic energy system. This system causes increased pH levels after extended training. Beta-alanine increases muscle carnosine content and improves performance in certain activities.
Beta-alanine is a very popular non-essential amino acid found in many pre-workout supplements. It's associated with decreased fatigue and potentially, increased performance in several activities. Let's take a look at some research on this supplement's safety.
Beta-alanine is an amino acid produced in the liver. Beta-alanine has seen a surge in popularity over the last few years. Of all the products contained in the Supplement Database, 36% of them contain beta-alanine, making it the second most popular ingredient behind caffeine.
