How Much Fish Oil Should You Take Each Day?

Fish oil that supplements contain come from cold-water fish, such as anchovies, salmon, mackerel, halibut, trout and tuna. They contain compounds known as omega-3 fatty acids, which are known to have many health benefits. The typical person in the U.S. eats a diet that is deficient in omega-3 fatty acids, but you can take fish oil pills which help in boosting your intake of this beneficial fatty acid.

A lot of people focus on the dosage of fish oil that they should take, like 1000 mg or 1200 mg, but in reality, it is the omega-3s that matter. There are two types of omega-3 fatty acids that you should focus on – EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These are found naturally in oily fish like those mentioned above.
