Deep sea fish oil is a dietary supplement that contains a nutrient called omega-3 fatty acids essential to bodily functions, which human bodies cannot produce. The omega-3s in fish oil are believed to have several preventative health benefits. Deep sea fish are thought by some to provide more potent oils and, thus, are presumed a better source of omega-3s than fish that live in shallower waters. Though tests remain inconclusive, nutritionists often point out that the only real difference between regular fish oil and oil from deep sea fish is the habitat from which the fish were taken. Some health experts think fish oil from deep waters may actually be more potentially harmful to the environment and consumers.

There are several possible health benefits of deep sea fish oil. Cardiovascular disease and its related complications like high cholesterol and high blood pressure may be alleviated by a proper balance of fatty acids. Studies have also suggested anti-cancer attributes. As fish oils promote brain function, there has been evidence that the product lessens the symptoms of depression, Parkinson’s disease, and even the incurable Alzheimer’s disease.

Despite the fact that fish are one of the best sources of Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), two types of fatty acids, fish do not produce omega-3s. Instead, they can accumulate the oils through their diet. These oils can come from various types of algae many shallow-water fish live off of.

Deep sea fish tend to be larger, predatory fish that eat smaller, algae-eating fish. It is for this reason that some people believe fish from deeper waters contain the most powerful oils. This fact also suggests, however, that deep sea fish are more likely to contain a buildup of toxins. Over time, these toxins could make a consumer of the fish oil sick. Some people point out that the most naturally oily fish are herring, sardines and anchovies, which are generally found in shallow waters.

Another reason the use of deep sea fish oil is often questioned is that, on average, fish from the depths of the ocean tend to have much longer life spans than shallow-water fish do. Environmentalists note that using fish with a slower reproduction rate is more harmful to the ocean’s ecosystem. Fish that live in shallow waters, on the other hand, are more abundant. Many accuse manufacturers of simply marketing deep sea fish oils as a more effective option simply to drive up the price.

Deep sea fish oil may quickly improve one's mood and, over time, prevent several types of ailments. Fish oils can have various adverse effects, especially for those with allergies to fish. If fish oils become oxidized, they may become rancid and should not be consumed. Before introducing any supplement into the diet, one may want to consult a doctor.

I think that deep sea fish oil supplements are truly more potent and effective than other kinds. My daughter is a bit short for her age and her doctor recommended fish oil supplements. We were using regular fish oil capsules and then switched to deep sea fish oil when the other one ran out. Ever since my daughter has started taking these, she has grown taller! Plus, her hair is looking better and much shinier. I think it's the fish oil supplements.

@fBoyle-- I don't think that mercury is a major issue for deep sea fish oil supplements. Most are made from salmon, sardines or mackerel. The product should specify what type of fish it is made from or you can ask the manufacturer. Plus, the fish used for fish oil supplements are thoroughly cleaned and then processed.

I personally use Alaska salmon deep sea fish oil. I don't have a specific reason for choosing this kind. The price was good so that's what I bought. I think most deep sea fish oil supplements are equal in quality, just stick to a well known brand.

Are fish that live in deep sea waters usually large?

I've read that large fish tend to have more mercury accumulated in their body. It's apparently better to take fish oil made from small fish for this reason. So I'm wondering if deep sea fish oil capsules have less or more mercury?
