Omega-3
 

These fatty acids are used in a number of ways within the human body. They help promote cardiovascular health and improved brain function. There are also some links with Omega-3 and reduced chances of cancer growth, but many of these studies are far from complete. Again this is one of those supplements that seem to have a lot of appeal now, and may pan out to be one of the greatest supplements to our health ever, but the research and the time are not quite there yet.
