There has been a growing interest in the benefits of Omega 3 by the science and health community and this is the reason why there has also been a growing recognition of fish oil in the news and commercials, and similar products have surfaced. Another term used to describe fish oil is "deep sea fish oils". What precisely is "deep sea fish oil" and why does it matter when purchasing a fish oil supplement?

Fish oil, in general terms, is not exactly derived from "deep sea" fish, or those species living in very deep waters (1800m) where light can barely penetrate the water. Herring, mackerel, anchovies and sardines (species that can be actually found in more shallow waters) are fish that have the most oil and have the top natural omega-3 concentrations.

Because these species of fish are lower on the food chain, have shorter life spans, and are small in size, they don't contain as much toxins compared to the bigger species that live longer (some can live as long as 70 years) and those that eat lots of smaller fish. This makes them better for fish oil pills. In addition, the above-mentioned species are most suitable because of the fact that they can reproduce rapidly and are easy to sustain.

To buy a product from a reputable company that specializes in fish oil may give some measure of assurance because there is actually no other way to be sure. For instance, a label that says "deep sea" could simply mean that the fish were taken from the open sea as opposed to from shallower waters. So, when you look for an omega-3 fish oil product, you would undoubtedly bump into different marketing phrases and terms that, as a result, would translate into confusion and misinformation. Because the benefits of fish oil are becoming more accepted, these products can be easily found in stores nowadays, pharmacies, and grocery stores. But even with all these marketing claims that can confuse the uninformed consumers, what then do you need to you look for?

First, examine the label for the detailed fish species stated above rather than comprehensive terms like "fish oil concentrates" or "marine lipids." Second, make sure that the precise amount of DHA and EPA (the Omega-3s in fish oil) in each serving is specified. It is a good idea to examine the DHA/EPA content against the price to ensure that you are getting the best value for your money. Before buying your fish oil, it wouldn't hurt to do some research and go for products from manufacturers with a reputation for high quality and purity standards. Although such standards are not legally imposed in the United States, there are international policies and third-party verification organizations that set the standards for fish oil quality. A reputable fish oil company will provide details about their manufacturing processes - from catching to canning / bottling - and provide proof of their claims validated by reliable third-party agencies.

What are omega-3 fatty acids and why would need them? Omega-3 fatty acids are not only good, but also essential, for our health. Because omega-3s can be best obtained from fish, taking fish oil is among the most excellent and safest ways to get these extremely valuable substances.

In more detailed terms, the benefits we can get from fish oil supplementation include the reduced risk of heart diseases, and inflammation. It can also help to deal with blood pressure, cholesterol and triglyceride levels. Furthermore, clinical studies and research indicate that using fish oil can lessen the symptoms associated to disorders like depression, schizophrenia, ADHD, and bipolar. Fish oil also facilitates brain improvement and helps it to function more effectively. Can we see now that there is undeniably a need for fish oil? However, it's not necessary to purchase a fish oil product that claims to be "deep sea fish oil."
