There are plenty of fish in the sea, and there is also plenty of fish oil supplements on the market! It seems that the choices are endless when it comes to a fish oil supplement. Most of the time, there is some kind of "cardiovascular" protection idea, along with some reference to arteries, brain health and even sometimes pregnant women? Really, it almost seems vague why someone would spend the money on a fish oil supplement. After all, there is no specific immediate effect for you to gauge if the fish oil supplement is actually working. Or is there?
