Beta alanine is the only naturally occurring beta-amino acid and is classed as a nonessential amino acid. It is widely used by athletes and often used in conjunction with L-Histidine. Our Beta Alanine capsules offer an 11:1 ratio of beta alanine to L-Histidine. It’s worth noting that beta alanine is most commonly known for its itching side effects after consumption, usually after a pre-workout.
