Beta alanine is an amino acid that binds with Histidine (another amino acid) to form Carnosine. Carnosine is a dipeptide that delays muscle fatigue,
thus allowing you to do another rep or two, which then stimulates greater
muscle growth!
Side Effects of Beta Alanine
Beta-alanine has been known to cause some of the following side effects: tingling sensation of the skin, flushing of the ears, scalp, forehead, arms, chest and buttocks approximately 20 minutes after taking. Taking low dosages in the beginning and slowly working your way up will keep these side effects barely noticeable. Not everyone will experience these side effects.
Studies have shown that continual use of Beta alanine for 4 weeks causes no toxicity and blood tests were found to be normal. Beta Alanine is considered to be safe and non-toxic at the manufacturers recommended dosages.
Does it make sense to supplement with carnosine instead of
beta-alanine?
It sounds like it would be the way to go, but carnosine is broken down in the intestines into the amino acids, beta-alanine and histidine. Then these amino acids are transported into the muscle tissue where they bind together to form....you guessed it, Carnosine! The problem is that most of the carnosine you started with is destroyed by this process, so you end up with a lot less carnosine in the muscle. You would have to take very large doses of carnosine to do any good. Beta alanine is already broken down, so it goes directly to the muscle to start forming carnosine.Clearly, supplementing with beta-alanine is a more efficient way to increase carnosine levels.
