Omega & fish oil
If there is one good health item that really sounds bad, it is "fatty acids". Together, the words "fatty" and "acids" are enough to turn many people off. However, you shouldn't be. In fact, it is something you need to make sure you take enough of every single day.
Don't worry, despite the words "fatty" and "acids", it is not going to add inches to your pant size or burn through parts of your body with acid. In this instance, you actually want fatty acids, as they will help improve the health and ability of every other cell in your body.
