Omega 3 is a kind of fish oil supplement that claims to improve the health of men and women if taken daily. These capsules are claimed to be beneficial in regards to memory, anti-aging, prostate health, reducing the likelihood of stokes, cardiovascular health and joint pain. Omega 3 is a substance found most commonly in fatty fish such as fresh salmon, tuna, mackerel, pilchards and sardines.

Over the last 100 years the western diet has shifted radically to include far less fish and thus the Omega 3 fatty acid. It is an essential fatty acid, which means is cannot be manufactured by our own body and therefore must be obtained through our diet alone. The thing is, most people's diet's contain an insufficient amount of omega 3.

Omega 3 is so healthy and has many benefits. It provides heart health, help with arthritis, lower blood pressure and has even been shown to be helpful with cancer. Omega 3 is the real deal. It is often looked at as a "wonder supplement," and that's exactly what many people are hoping.

Fatty acids can have common names, systematic names and numerical names. Most commonly fatty acids are referred to by their common names and numerical names. Fatty fish such as mackerel, trout, salmon, herring, sardines and tuna are high in omega-3 fatty acids. People who eat relatively large quantities of fish (rich in omega-3 fatty acids) seem to have lower rates of cardiovascular disease, as well as depression. Fatty acids are the basis of fats and oils, and, despite popular belief, are necessary for overall health. These fatty acids are termed "essential" because your body cannot manufacture them by itself.

Oily fish (such as sardines, anchovies, mackerel, and salmon) are the only known natural sources of Omega-3 EPA/DHA. ALA is found in plants, such as flax and chia. Oily fish is by far the most significant source of omega-3s (and the general principle is the colder the water, the more omega-3 in the fish). The EPA and DHA -- or “long-chain” fatty acids -- we need for good health are produced by algae, which in turn are eaten by fish such as mackerel, sardines and salmon.
