I can't believe I just posted an article about supplementation and forgot one of the most basic and important ones: fish oil!
Fish oil is great for your joints, cardiovascular system, and helps reduce total body inflammation from a variety of reasons. It's the closest thing we have to a miracle pill.
You want to look at the side of any fish oil bottle and see what the EPA and DHA concentrations are. Then take as much as needed to reach 3g of the oils combined. I've heard that the encapsulation process oxidized the fatty acids, so it's best to (gag) take it in liquid form straight from the bottle. Hey, it's for your health and performance!
