Optimum Nutrition Fish Oil 100. When you’re training hard, your body has greater nutritional needs. It’s not always possible to source these solely from your diet every single day.. Fish Oils contain long-chain fatty acids, including the essential fats DHA and EPA that cannot be made by your body. Consuming them through foods like salmon or mackerel and supplements such as the Fish Oil Softgels is the only way to guarantee that you’re meeting your body’s requirements.
