    Product Description

    N-acetyl Taurine is a derivative of the sulfur-containing amino acid taurine (Item No. 27031).1,2 It is formed endogenously from taurine and acetyl-CoA (Item Nos. 16160 | 21219). Urinary N-acetyl taurine levels are increased after alcohol consumption due to its formation from the acetate produced via alcohol catabolism.1 N-acetyl Taurine levels are also transiently increased in the serum and urine after endurance exercise.2

    WARNING This product is not for human or veterinary use.
