- High evidence6 studies
Across 6 studies, 5 reported beneficial effects of L-carnitine on reducing triglyceride levels, with one neutral finding and no harmful results. Effect sizes were predominantly small, although one high-quality RCT showed a large effect. The evidence is drawn mainly from meta-analyses and a recent RCT, with a median study duration of 42 days (where reported), suggesting effects can appear within 6 weeks. The most common dose range was around 2–3 g/day, studied primarily in clinical populations such as women with PCOS and adults with metabolic or kidney conditions.

- LowavocadoAcross 4 studies, only 1 reported a moderate beneficial effect on triglycerides, while 3 found neutral effects. The beneficial study used 1 avocado per day (∼180 g) for 21 days in adults with elevated triglycerides, showing a 17.4% reduction. However, the evidence is predominantly neutral and inconsistent, with most studies showing small non-significant effects.1 beneficial3 neutral4 studies
- Lowgreen teaAcross 3 studies, 1 reported a beneficial moderate-sized effect of green tea on reducing triglyceride levels, while 2 found neutral effects. The beneficial finding came from a meta-analysis showing short-term (<8 weeks) green tea intake at doses below 3000 mg/day significantly reduced triglycerides (SMD: -0.74). Evidence base is small (only 3 studies) — conclusions should be considered preliminary. · Dose: <3000 mg/day1 beneficial2 neutral3 studies
- Very lowReishiAcross 3 studies, 1 reported a small beneficial effect of Reishi (Ganoderma lucidum spore oil) on reducing triglyceride levels, while 2 found neutral results. The beneficial effect was observed in a randomized controlled trial with 110 dyslipidemic participants over 12 weeks, using a spore oil form. The median study duration was 63 days, and effect sizes across all studies were consistently small. The evidence base is very small (only 3 studies), so conclusions are preliminary.1 beneficial2 neutral3 studies
