Nava Wholefoods is the first to market with a 100% Vegan range of amino acids. Beta-Alanine is a rate limiting amino acid, meaning it controls the amount of secondary product that exists in the human body. Beta Alanine works by increasing the amount of Carnosine in the muscle tissue. Carnosine is responsible for the buffering of Hydrogen, which is an accumulative toxin that rises as a result of high-intensity exercise and causes fatigue. Essentially, if you have more intramuscular Carnosine, you can clear lactic acid faster (which can slow you down whilst exercising) and increase explosive movements allowing you to train at a higher intensity. Beta Alanine can also cause a tingling sensation on the skin. This is a very common and perfectly normal side effect and is actually stimulating the body's nerve endings which is brilliant for explosive power.
