No, in fact that’s generally why people take an omega-3 supplement – because they aren’t eating fish. Also keep in mind that not all omega-3 fatty acids (FA) 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 scientist attribute to the health benefits of fish consumption. Therefore if you are looking for the specific benefits, such as maintaining heart, brain, hearing and vision health, attributed to omega-3s, look for fish oil capsules containing ~600mgs of omega -3s made up of 360mgs EPA & 240mgs DHA. Take 1 capsule daily if not consuming 2-4 svgs/wk of fatty fish unless a qualified physician advises more for a specific condition.
