β-Alanine (slow release) It is an amino acid structurally similar to L-Alanine, which is synthesized by the liver. Β-Alanine is not used to form proteins in the human body. Its main role is to serve as a precursor to synthesize carnosine, which is a dipeptide associated with muscular work capacity, particularly during relatively intense and prolonged exercises.

Although carnosine can be consumed from meat and poultry, it is degraded into its precursor amino acids (β-Alanine and Histidine). Histidine is easily taken up by the muscle but β-Alanine requires higher blood concentrations to increase muscle carnosine concentrations. This effect can only be achieved with additional intakes of β-Alanine in the form of a dietary supplement and not through a normal diet.
