No, and not all omega-3 fatty acids have equal health benefits. The two most studied omega-3 fatty acids are the 20-carbon eicosapentaenoic acid (EPA) and the 22-carbon docosahexaenoic acid (DHA). These are the primary compounds in fish oils that have health benefits. Therefore, if you are looking for theses specific benefits, including maintaining heart, brain, hearing and vision health, look for fish oil capsules containing ~600 mg of omega -3s made up of 240 mg EPA & 360 mg DHA. Take 1 capsule daily if you don’t eat 2-4 servings of fatty fish, unless a qualified health professional advises more for a specific condition.
