Taurine
Taurine is technically not an amino acid in the strict sense (it lacks a carboxyl group) but functions like one and is one of the most abundant free amino-style compounds in the body, especially in the heart, brain, and skeletal muscle.
Why It Matters
Taurine regulates calcium handling in muscle cells, supports bile acid formation for fat digestion, and acts as an antioxidant inside mitochondria. Studies show it can reduce exercise-induced muscle damage and improve endurance time to exhaustion at doses around 1 to 3 grams.
Vegans tend to consume less taurine because most dietary taurine comes from animal products, particularly seafood and dark meat poultry. The body can synthesize some, but supplementation is common in pre-workouts and BCAA blends.
How to Spot It on a Label
Taurine is listed by milligrams on pre-workout, BCAA, and energy drink labels. Typical doses run from 500mg in light formulas to 2 grams in performance-oriented products. It is also present in small amounts in some whey powders, listed at the bottom of the amino panel.
