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).

Effect of Eurycoma longifolia standardised aqueous root extract-Physta® on testosterone levels and quality of life in ageing male subjects: a randomised, double-blind, placebo-controlled multicentre study
Food & Nutrition Research (2021) · Rct · n=105
105 men aged 50-70 with testosterone <300 ng/dL took Physta 100 mg, 200 mg or placebo daily for 12 weeks.
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.
The dose points come from one randomised, placebo-controlled trial of 105 men aged 50 to 70 with low testosterone (PMID 34262417), who took 100 mg or 200 mg a day of a standardised water extract (Physta) for 12 weeks. Total testosterone rose more than on placebo at week 12 with 100 mg, and at weeks 4, 8 and 12 with 200 mg. The trial did not report that 200 mg beat 100 mg directly, so no optimal dose is given. It found no clinically relevant safety changes at either dose, which is why the ceiling is 200 mg. An uncontrolled study of 76 men with late-onset hypogonadism also used 200 mg a day for a month and found testosterone rose (PMID 21671978). A meta-analysis of 5 trials found a significant rise in total testosterone (PMID 36013514) but does not compare doses.
