Do all fish oil supplements have the same amount of Omega-3?

Fish oil supplements vary in the amount of omega-3 fatty acids they contain. The two omega-3 fatty acids that are thought to offer health benefits and are commonly contained in fish oil supplements are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Some fish oil supplements may have more EPA than DHA, and in others the opposite might be true. A common amount is 180 milligrams (mg) of EPA and 120 mg of DHA per supplement, but check labels carefully. Be sure to talk to your doctor before taking fish oil supplements or any dietary supplements.
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 360 mg of EPA & 240 mg of DHA. Take 1 capsule daily if you don’t eat 2-4 servings of fatty fish per week, or more if a qualified health professional advises you to do so because of a specific health condition.

d minerals to fiber and herbal remedies, these supplements are not regulated in the same way as either food or medicine. Some of them are backed by solid research, others are folk remedies or proprietary cures. If your diet does not include enough of certain vitamins or minerals, a supplement may be a good idea. Natural treatment for conditions like constipation may be effective. But because these substances are unregulated, it is always a good idea to educate yourself about the products and to use common sense when taking them. This is even more true if you are pregnant or taking a medicine that may be affected by supplements.
