Micronutrients & recovery
Fish oil supplements provide a statistically significant but modest reduction in systolic blood pressure (2.3 mmHg) in adults with hypertension.
Taking fish oil supplements containing omega-3 fatty acids (EPA and DHA) can lower systolic blood pressure by about 2.3 mmHg. While the effect is smaller than lifestyle changes, it is a statistically significant benefit. Supplements were taken several times a day, with doses ranging from 0.1 to 17 grams per day.
Robust statistically significant effects were found for... fish oil supplements: mean reductions in systolic blood pressure of... 2.3 mmHg (95% CI: 0.2–4.3)
Why this rating
Based on 8 trials (4 parallel, 4 crossover) with consistent findings, though heterogeneity was noted in some analyses.
