Reviews found a benefit (9)

“Taurine supplementation effectively ameliorates key pathological features of PASC, including metabolic perturbation, endothelial dysfunction, and oxidative stress.” PMID 41803812
“Supplementation also improved blood pressure and exercise capacity, though no significant effects on neurocognition were observed.” PMID 41803812
“Taurine supplementation may effectively improve cardiometabolic risk factors in adults, underscoring its potential to reduce the incidence of cardiometabolic diseases.” PMID 41275513
“Menthol (SMD = -1.83, 95% CI [-3.15, -0.51]; P-score = 71.04%) and taurine (SMD = 0.91, 95% CI [0.08, 1.73]; P-score = 12.75%) demonstrated significant positive effects on endurance.” PMID 40647246 · 2 reviews
“Taurine ingestion in such conditions may lower heat strain, which is likely through its augmentation of thermal sweating.” PMID 39884667
and 3 more.
