Also known as Omega-3 oil, fish oil is thought to help in the reduction of free radicals. Our diets are full of Omega-6 oil that is often found in grains. It is believed that Omega-6 causes silent inflammation in the body that leads to different syndromes later in life. Omega-3, naturally found in fish, reduces the Omega-6. I find that it also helps me recover and keeps my joints from aching. Similar to protein powder, it is important to find a good quality fish oil. Once again, that doesn’t mean expensive. Look at the label to check the amount of Omega-3 per serving. The general consensus is 2000mg-4000mg per day. The more quality supplement will have a higher mg count per serving.
