Prolab® Beta Alanine Extreme™ fuels your body’s ability to increase muscle carnosine synthesis by 42%! What is carnosine? Carnosine is composed of beta alanine and L-histidine and your body simply cannot synthesize carnosine without beta alanine. Carnosine is found in large amounts in Type II or “fast twitch” muscle fibers, which are used in explosive movements like weight training and sprinting. Carnosine helps activate enzymes responsible for generating muscle contractions. Supplementing with beta alanine has shown to significantly delay muscle fatigue to help you squeeze out the last growth stimulating reps.
Prolab Beta Alanine Extreme not only includes both CarnoSyn® beta alanine and L-histidine but is also very specifically dose calibrated in divided doses for improved tolerance with maximum retention. Beta Alanine Extreme – backed by science, formulated for results.
