Across 3 studies, all reported beneficial moderate-sized effects of ellagic acid (a compound found in raspberries) on reducing triglyceride levels. The most-studied dose was 180–200 mg ellagic acid per day, and effects were typically observed at 8 weeks (median study duration 56 days). The evidence comes primarily from clinical populations with metabolic liver disease (MASLD or NAFLD).
- Effective dose range: 180–200 mg ellagic acid per day
- Studied populations: people with metabolic dysfunction-associated steatotic liver disease (MASLD) or non-alcoholic fatty liver disease (NAFLD)
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). Additionally, the studies specifically tested ellagic acid, a compound found in raspberries, not whole raspberry supplements; the effect of whole raspberry or other raspberry constituents on triglycerides is not directly tested.
