Caution. Can cause transient tingling (paresthesia) at common doses.

Summary

Beta-alanine is a non-essential amino acid that combines with histidine to form carnosine in muscle, where it buffers hydrogen ions during high-intensity efforts. Daily supplementation increases muscle carnosine over weeks and improves performance in efforts lasting roughly 1-4 minutes. A harmless tingling sensation is common at typical single doses and can be reduced by splitting doses or using sustained-release forms.
