Optimum Nutrition Fish Oil Review

Fish oils are known to have many powerful benefits in human health. That is because of its long-chain fatty acids called omega-3 fatty acids, more specifically the docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). 

DHA and EPA Omega-3 fatty acids support many human body functions, including the brain, heart, joints, bones, and numerous metabolic functions. In addition, fish oil also helps increase good cholesterol or High-density lipoprotein (HDL) and is a good anti-inflammatory.

The only way to get DHA and EPA is through food as the human body cannot produce it on its own. That is why the American Heart Association recommends consuming at least 2 servings of fish (particularly fatty fish) per week. A serving is 3.5 ounces cooked or about ¾ cup of flaked fish. 

Fishes like mackerel, tuna, lake trout, herring, salmon contain a high amount of these essential fats. However, not everyone can consume the recommended amount daily. Luckily, fish oil supplements are widely available and can be a great substitute for those who cannot obtain enough. 

Optimum Nutrition — one of the most talked-about brands when it comes to nutritional products and supplements manufactures fish oil soft gels. Unlike other fish oils, this has a special coating that eliminates the fishy aftertaste.
