Anthocyanins and Reduced Triglyceride Levels

Research synthesisLow evidenceSmall effect3 studies · 2 beneficial · 1 neutral · 0 harmful

Across 3 studies, 2 reported beneficial small-sized effects on triglyceride levels, while 1 found neutral results. The most studied dose was 320 mg/day, primarily in clinical populations (type 2 diabetes, cardiometabolic risk). Effects were typically observed at durations of 8–24 weeks (median 16 weeks).

  • Effective dose range: 320 mg/day
  • Studied populations: Adults with type 2 diabetes or cardiometabolic risk factors

Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. The largest meta-analysis (703 participants with type 2 diabetes) reported a significant reduction in triglycerides, but a recent RCT (99 participants with cardiometabolic risk) found no effect, suggesting possible population-specific effects or residual confounding. The observed effect is small and may not be clinically significant for all.
