Taurine and Improved Exercise Capacity

Research synthesisModerate evidenceSmall effect3 studies · 3 beneficial · 0 neutral · 0 harmful

Across 3 studies, all reported beneficial effects on exercise capacity, with two showing small effects and one showing moderate effect. The evidence is predominantly small in magnitude. Studies involved clinical populations (long COVID, heart failure) and used doses ranging from 500 mg to 6 g per day.

  • Effective dose range: 500 mg to 6 g per day
  • Studied populations: clinical populations (long COVID, heart failure)

Caveats: Available evidence is overwhelmingly positive — clinical literature in this area is subject to publication bias (null-result studies are less likely to be published or indexed). Evidence base is small (only 3 studies) — conclusions should be considered preliminary. Studies were short-term (median 14 days) and focused on clinical populations — generalizability to healthy individuals or long-term use is unclear.
