What it is
A non-proteinogenic beta amino acid. Available as oral powders, capsules, and tablets.
How it works
Rate-limiting precursor for the synthesis of intramuscular carnosine (beta-alanyl-L-histidine), which buffers intracellular hydrogen ions during high-intensity contraction.
Where it's used
Used as a dietary supplement in athletic and resistance-training contexts; characteristic paresthesia at higher single doses is common.
FDA-approved use
Regulated as a dietary supplement.
Tracking it
Beta-Alanine is oral, which makes consistency the whole game — a simple daily check-off with a reminder beats memory every time. with a half-life of about 30 minutes, a dose log also lets a tracker model the relative amount still in your system between doses.
