Beta-Alanine is a non-essential amino acid that increases muscle power, strength and mass as well as increases anaerobic and aerobic endurance. It also delays muscle fatigue.

L-Histidine is an amino acid which is present in proteins. It is furthermore one of only twenty amino acids located there and is considered essential for human infants. Older children and adults are able to synthesize histidine, which thereafter is deemed non-essential. Histidine is viewed as a precursor for the biosynthesis of histamine, but also of carnosine. The enzyme necessary for the synthesis of histidine into histamine is called histidine decarboxylase. Histidine transmiase is able to transfer L-Histidine into (imidazol-5-yl)pyruvate and L-glutamate. L-Histidine is deemed necessary also for the utilization and regulation of other essential trace minerals by the human body, these minerals are manganese, iron, zinc, copper and molybdenum. With help of histidine kinase, protein L-Histidine and adenosine triphosphate can be converted into adenosine diphosphate and protein N-phospho-L-histidine.
