Marine n-3 Fatty Acids and Prevention of Cardiovascular Disease and Cancer
The New England journal of medicine (2019) · Rct · n=25871
During a median follow-up of 5.3 years, a major cardiovascular event occurred in 386 participants in the n-3 group and in 419 in the placebo group (hazard ratio, 0.92; 95% confidence interval [CI], 0.80 to 1.06; P=0.24).
Omega-3 fatty acids for intermittent claudication
The Cochrane database of systematic reviews (2024) · Meta analysis · n=1830
Omega-3 compared with a control may have little to no effect on ankle-brachial index (MD -0.02, 95% CI -0.08 to 0.04; 3 studies, 168 participants; very low-certainty evidence).
A systematic review and meta-analysis of the omega-3 fatty acids effects on brain-derived neurotrophic factor (BDNF)
Nutritional neuroscience (2024) · Meta analysis · n=587
12 RCTs with 587 subjects: omega-3 supplementation increased serum BDNF versus placebo (SMD 0.72, 95% CI 0.28 to 1.15), with high heterogeneity (I2 = 84.39%).
Raspberry Leaves and Extracts-Molecular Mechanism of Action and Its Effectiveness on Human Cervical Ripening and the Induction of Labor
Nutrients (2023) · Review
The majority of women apply raspberry leaves during pregnancy to induce and ease labor.
A Review on Berry Seeds-A Special Emphasis on Their Chemical Content and Health-Promoting Properties
Nutrients (2023) · Review
A different part of the plant: berry seeds, not the leaf. Raspberry leaf is dosed as 1-2g dried leaf as tea for uterine and menstrual use, and this paper reviews the chemical content of berry seeds. Read it as species-level context, not as leaf evidence.
Phenolic Composition, Mineral Content, and Beneficial Bioactivities of Leaf Extracts from Black Currant (Ribes nigrum L.), Raspberry (Rubus idaeus), and Aronia (Aronia melanocarpa)
Nutrients (2020) · Review
Narrative review of the phenolic compounds and minerals in leaves of black currant, raspberry and aronia, not raspberry alone.
The points are the dose bands of a meta-analysis of 10 randomised trials with 1,426 adults (PMID 37028202): EPA-rich products at 1 to under 2 g of EPA a day reduced depression severity (SMD -0.43), while 2 g a day or more did not (SMD -0.20, not significant), so the 2 g point is plotted as no effect. Doses are grams of EPA, not EPA plus DHA. The Cochrane review of 33 placebo-controlled trials found a small to modest effect, unlikely to be clinically meaningful and rated very low certainty, with no difference in remission or response (PMID 34817851). No trial compared doses directly.
Both points come from one phase II RCT in 198 adults with knee osteoarthritis (PMID 35799169), which gave 200 mg or 400 mg of leaf extract daily for 12 weeks. The primary endpoint, WOMAC pain, did not differ from placebo at either dose. Walking pain on a VAS fell more than placebo at 400 mg only, so 200 mg is plotted as no effect. Doses above 400 mg were not tested, and a single trial cannot establish an optimal dose or a safety ceiling.
