Across all 5 studies, flaxseed supplementation consistently shows beneficial effects on reducing triglyceride levels, with 5 of 5 studies reporting statistically significant reductions. The predominant effect size is moderate, with one large effect observed in a meta-analysis. The most studied populations are individuals with type 2 diabetes and those with dyslipidemia or coronary artery disease, with a median study duration of 80 days, indicating effects are typically observed after 8-12 weeks.
- Effective dose range: 16-28 g/day
- Studied populations: people with type 2 diabetes, patients with dyslipidemia, patients with coronary artery disease, patients with non-alcoholic fatty liver disease
Caveats: Available evidence is overwhelmingly positive — clinical literature in this area is subject to publication bias (beneficial findings are more likely to be published or indexed). Only 2 of 5 studies explicitly reported duration, limiting confidence in the timing of effects. Doses varied across studies (16-28 g/day) and some studies did not report exact doses, making specific dose recommendations less precise.
