Across all 3 studies in the database, flaxseed supplementation showed beneficial moderate-sized effects on reducing triglyceride levels, with all studies reporting statistically significant findings. Evidence primarily comes from clinical populations (type 2 diabetes and coronary artery disease), and effects were typically observed after 90 days of supplementation, though only one study reported duration.
- Effective dose range: 16 g daily (single study reporting dose)
- Studied populations: people with type 2 diabetes, patients with coronary artery disease
Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. Only one of three studies reported a specific dose (16 g daily), limiting dose-response conclusions. 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). All studies focused on clinical populations (type 2 diabetes, CAD) — generalizability to healthy individuals is unclear.
