Taurine
Taurine is a sulfur-containing amino acid synthesized in the body that is known to play roles in antioxidant defense, cell membrane stabilization, and electrolyte balance regulation. Several RCTs have reported improvements in aerobic performance and reductions in post-exercise muscle damage markers and DOMS. While widely recognized as an energy drink ingredient, a growing body of research has examined its effects as a standalone supplement.

Effects reported in research
Improvements in aerobic exercise performance and oxygen consumption efficiency have been reported in research
Reductions in post-exercise muscle damage markers (CK, LDH) and delayed onset muscle soreness (DOMS) have been observed
Reduction of oxidative stress through antioxidant mechanisms is expected
Support for muscle contraction function through electrolyte balance regulation has been suggested
Dosage & timing
- The commonly studied dose is 1–3 g per day.
- Many trials have used supplementation 1–2 hours before exercise or immediately post-exercise.
- Taking it with meals may help reduce gastrointestinal discomfort.
Cautions
- •Serious adverse effects are rarely reported at typical doses (1–3 g/day), but long-term safety data at high doses are limited.
- •Individuals with impaired kidney function should exercise caution due to potential effects on excretion.
- •When consuming through energy drinks, be mindful of excess caffeine and sugar intake.
- •Those with pre-existing conditions, pregnant or breastfeeding individuals should consult a doctor before use.
