Beta Alanine is a naturally occurring beta-amino acid. Beta Alanine’s main effect comes from its ability to boost the synthesis of carnosine, which in turn can help buffer lactic acid, reduce the onset of fatigue and increase exercise intensity and duration. Many users experience intense vasodilatation/pumps from the very first dose of Beta Alanine as carnosine is a powerful precursor in generating nitric oxide synthase. It works very well when taken with other supplements and is the core active ingredient on most pre-workout formulas on the market today. Strength athletes may take Beta Alanine with Creatine Monohydrate to enhance muscle power and size. Whereas Beta Alanine and Citrulline Malate has become the recommended supplement blend by endurance experts. Note: A common side effect of Beta Alanine, especially on first use, is flushing or tingling/itching of the skin particularly around the hands and face (paresthesia). This is well documented, harmless and will pass quite quickly.
