Beta-Alanine is known as a rate limiting amino acid, which essentially means it controls the amount of a secondary product that exists in the human body. In this instance, the amino acid, or more specifically the di-peptide (meaning 2 amino acids bound together to make 1) is known as Carnosine. 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. Well, as mentioned above, Beta-Alanine is the sole controlling amino acid responsible for the levels of intramuscular Carnosine available. What this means is, that unless you supplement with Beta-Alanine, you cannot increase Carnosine levels. In short - you need Beta Alanine to buffer lactic acid build up for better pumps and super human endurance! This one is a great option too being naturally sourced, non GMO, vegan, gluten free and pesticide free.Recommendations: Take one serving with water before intense exercise.
