Taurine and Reduced Fasting Blood Glucose Levels

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

Across 3 meta-analyses, all 3 reported statistically significant beneficial effects on fasting blood glucose, with effect sizes ranging from small to moderate. The most commonly studied dose was 3 g/day, and effects were observed in diverse populations including general adults, overweight/obese individuals, and those with long COVID. Study durations varied, with one trial lasting 5 days.

Effective dose range: 3 g/day (range 0.5–6 g/day)
Studied populations: adults with overweight/obesity and those with long COVID (post-acute sequelae of SARS-CoV-2 infection)

Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. 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). Study durations were not consistently reported, limiting assessment of time to effect. No specific supplement form was identified across studies.
