Thorne Beta Alanine-SR, 120 Tablets (800 mg per Tablet)

Thorne's Beta Alanine-SR is a sustained-release beta-alanine supplement designed to support muscle output and endurance during training, with a formulation that aims to minimize side effects like tingling. It provides 1.6 grams of beta-alanine per serving from CarnoSyn®, a patented ingredient clinically studied for athletic performance benefits. The product is intended for athletes, fitness enthusiasts, and aging individuals looking to maintain muscle health, with vegetarian or plant-based diets noted as a potential use case due to lower carnosine levels from animal protein sources.

Key features include the PureTab® sustained-release delivery system, which extends absorption to provide long-lasting effects while reducing the tingling sensation often associated with beta-alanine. It carries NSF Certified for Sport certification, indicating batch testing for label accuracy and absence of nearly 300 banned substances, making it suitable for competitive athletes. The tablets are manufactured in the USA using domestic and imported ingredients, available in a 120-count bottle providing 60 servings.
