Taurine supplement may boost muscle endurance, small study hints
NCT ID NCT07654946
First seen Jun 27, 2026 · Last updated Aug 27, 2026 · Updated 2 times
Summary
This study tests whether taking taurine (a common supplement) can improve how long your leg muscles can work before getting tired. Researchers will measure muscle function using a light-based technique (NIRS) and compare taurine to a placebo in 34 healthy young adults. The goal is to see if taurine helps muscles resist fatigue and if NIRS can predict endurance.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- taurine
- What this could lead to
- If successful, this could show that taurine supplements improve muscle endurance and reduce fatigue during exercise.
- What could go wrong
- This is a small, early-stage study with only 34 healthy young adults. Results may not apply to athletes or older people, and taurine may show no benefit over placebo.

Inclusion Criteria: * Capable and willing to give written informed consent * Capable of understanding inclusion and exclusion criteria * No medical condition that would limit participation in supervised exercise * No current prescription medications known to impact mitochondrial function * Sedentary or recreationally active (self-report average MVPA \< 300 mins/week) * Willing to allow researchers to use data for research purposes Exclusion Criteria: * Self-report history of diabetes mellitus * Self-report history of cardiovascular, peripheral vascular, cerebral vascular, pulmonary, or renal disease * Self-report history of uncontrolled hypertension (resting systolic blood pressure \> 180 mmHg or diastolic blood pressure \> 100 mmHg) * Self-report history of blood clotting disorders * Self-report history of sickle cell trait * Self-report history of myopathy leading to muscle loss, weakness, severe cramps, or myalgia * Self-report history of musculoskeletal disorders * Self-report history of lower limb musculoskeletal injuries that may cause significant differences in the functional capacities of the right and left legs * Self-report history of neurological disorders * Active tobacco, E-cigarette, or nicotine use * Recent (within previous 2 weeks) consumption of energy drinks or supplements containing ≥ 1 gram of taurine on \> 2 days/week * Actively taking medications to treat blood-clotting disorders * Any condition that, in the judgement of the Principal Investigator, may interfere with study participation and adherence to the protocol * Participants may be excluded if measured adipose tissue thickness is \> 2.0 cm at the site of NIRS assessment or if the accessor is unable to obtain high-quality NIRS signals
