Omega-3 Fatty Acid Supplementation in Patients with Hypertension

Recommended Intake and Cardiovascular Benefits

The American Heart Association recommends consuming fatty fish at least twice weekly or 500 mg EPA+DHA daily for general cardiovascular health, as supported by the Arteriosclerosis, Thrombosis, and Vascular Biology journal 1
For patients with documented coronary heart disease, 1 gram EPA+DHA daily is recommended for secondary prevention, according to Praxis Medical Insights 2
The American College of Cardiology suggests that patients with hypertriglyceridemia and hypertension may benefit from 2-4 grams EPA+DHA daily under physician supervision, as stated in Arteriosclerosis, Thrombosis, and Vascular Biology and Praxis Medical Insights 1, 2

Middle-aged and older adults derive greater cardiovascular benefits from fish consumption, with benefits far outweighing potential risks, as reported in Arteriosclerosis, Thrombosis, and Vascular Biology 1
Patients taking more than 3 grams daily should do so only under physician supervision due to potential bleeding risk, although this risk remains theoretical, as noted in Arteriosclerosis, Thrombosis, and Vascular Biology and Praxis Medical Insights 1, 2

Omega-3 fatty acids benefit multiple cardiometabolic risk factors, including lipids, vascular reactivity, and cardiac function, and possess antithrombotic, anti-inflammatory, and anti-oxidative actions, as demonstrated in Circulation 4, 5
For patients with heart failure (NYHA class II-IV), omega-3 PUFA supplementation of 1 gram daily is reasonable as adjunctive therapy to reduce mortality and cardiovascular hospitalizations, according to Circulation 5
Meta-analyses demonstrate dose-dependent reductions in myocardial infarction, coronary heart disease, and cardiovascular mortality, as reported in Arteriosclerosis, Thrombosis, and Vascular Biology and Circulation 6
