Aren’t all Fish Oils the same?

Contrary to belief, fish Oils are not the same and it is important to learn some basic facts before you run out and purchase your next bottle of liquid or capsules. Quality of fish oil supplements vary greatly!
Each grade of fish oil is distinguished from the other by its purity and concentration of long-chain omega-3 fatty acids. Crude fish oils are the least expensive and are the ones most likely to contain some levels of contaminants including PCBs, DDT and organic mercury.
When choosing a high dose fish oil remember that knowledge is power and not all fish oils are manufactured the same. Some fish oils may even be dangerous when taken in high doses.

With many choices of fish oil available, and with so many pro and con opinions written about each, it is easy to become confused. So when it comes time for you to choose a fish oil make sure you do your homework and choose wisely – your health depends on it.

When choosing a fish oil that you will be ingesting in high doses it is crucial that you choose one that is pure and free of contaminants, toxins, and mercury. How can you, the consumer, tell the difference?

Currently there are three grades of fish oil available on the market today:
1. Cod Liver Oil;

2. Health-food Grade Fish Oil; and,

3. Pharmaceutical-Grade Fish Oil

Cod Liver Oil
Cod Liver Oil is the lowest quality fish oil and like the name implies it is manufactured from the livers of Cod fish. It has the lowest concentration of long-chain omega-3 fatty acids and contains the highest levels of contaminants such as organic mercury, PCB’s, and DDT. Cod Liver Oil may also contain a high level of Vitamin A.
Cod Liver Oil is not recommended for high dose consumption.

A typical serving of Cod Liver Oil contains 500 mg. of long-chain omega-3 fatty acids.

Health-food Grade Fish Oils

Most health-food grade fish oils are manufactured from fish body oils. Fish oils can be manufactured from a single fish species or from several fish species.

Fish size and their relative rank in the food chain can help us understand the level of contaminants that may be found in health-food grade fish oils.

Small fish, such as sardines and anchovies, don’t live long so are less prone to accumulate environmental pollutants. Larger fish, such as salmon and mackerel, live longer so they are more likely to contain higher levels of pollutants.

If the label says it comes from a particular species of fish, such as salmon, then it is probably is health-food grade fish oil. This type of fish oil can be found in most health food and vitamin supplement stores.

A slightly more purified type of health-food grade fish oil is available which includes oils that have been subjected to a limited amount of molecular distillation to remove some of the cholesterol. These types of fish oils are usually labeled as “cholesterol-free”.

“Fish Oil Concentrate” is yet another type of health-food grade fish oil. Fish oil concentrates consist of ethyl esters of the fish oil that have been subjected to fractional cooling. The solidified saturated fats are removed leaving behind a more concentrated solution of long-chain omega-3 fatty acids. A typical one-gram capsule of thermally fractionated health-food grade fish oil contains up to 500 mg. of long-chain omega-3 fatty acids.

Typical health-food grade fish oils may contain varying amounts of contaminants. In addition, the fractional cooling method does not necessarily remove all the PCB’s or the long-chain monoene fatty acids that may give rise to gastric distress or upset. Due to the varying amounts of contaminants that could still be contained in health-food grade, it is questionable as to whether it is safe at high levels.

A typical one-gram capsule of health-food grade fish oil contains approximately 300 mg. of long-chain omega-3 fatty acids.

The Newest Generation of Fish Oils — Pharmaceutical Grade Fish Oil

Pharmaceutical-grade fish oils start with thermally fractionated health-food grade fish oils. These oils are then distilled, using a highly complex refining technology, into fractions rich in long-chain omega-3 fatty acids. According to manufacturers, it typically takes about 100 gallons of health-food grade fish oil to make one gallon of pharmaceutical-grade fish oil.

Individual fractions are then combined to provide a 2:1 ratio of Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA) for the finished fish oil product.

Scientific studies conducted with pharmaceutical-grade fish oils that used a 2:1 ratio of EPA and DHA reported significant clinical benefits.

Pharmaceutical-grade fish oils are exceptionally low in long-chain monoenes, PCB’s and other pollutants. Pharmaceutical-grade fish oils are believed to be the safest to take in high doses. A typical one-gram capsule of pharmaceutical-grade fish oil will have a minimum of 600 mg. of long-chain omega-3 fatty acids.

Pharmaceutical-grade fish oils are a fairly new product and a good-quality source may be difficult to find. In addition, pharmaceutical-grade fish oils definitely cost more – sometimes twice as much. This increased cost is an outcome of the complex process used to remove impurities. Each step in the refining process adds additional production costs.

For instance, the pharmaceutical grade fish oils that Dr. Barry Sears discusses in his books, The OmegaRx Zone, The Anti-Inflammation Zone and Toxic Fat start with a health food grade fish oil which then goes through nine additional steps to make it pharmaceutical grade quality.

Pharmaceutical-grade fish oils generally taste better and the amount of long-chain monoenes, which cause gastric distress, are dramatically reduced.

Are your Fish Oil Supplements Pure?

All Fish Oil Supplements are not Created Equal

Although many people may not know what fish oil is or what it can do for them, it is a highly beneficial supplement. It is taken from oily fish such as salmon, sardines, mackerel and trout that are typically cold water fish. The fish are open sea fish that live closer to the top of the ocean rather than the bottom.

What is Fish Oil?

Fish oil is found in the fillet of certain fish as well as in the cavity of the belly. It contains omega-3 fatty acids, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). Omega-3 fatty acids are not produced by these fish. They acquire the fatty acids from eating microscopic algae or other fish that have eaten the algae.

The oil contained in the liver of fish also contains omega-3 however; Vitamin A is also present and can be dangerous if high levels are consumed. This is why the oil should come from the fillet rather than the liver.

Some fish that are high in these fatty acids are predatory fish such as mackerel, albacore tuna, flounder and salmon. For this reason they have high levels of omega-3 fatty acids, but they may also get contaminants from the fish they eat.

The contaminants are mercury, chlordane, PCBs and dioxin. This is one reason the FDA has recommended limiting the amount of this type of fish that you eat. Many of the fish used for these oils are farmed salmon, therefore the presence of contaminants is not as much of a concern as with fish that are caught in the open sea.
Pure Fish Oil

It is very important that the fish oil you use does not contain metals, toxins and contaminants that can harm rather than help. This is why the oil must have been molecularly distilled. This is a process that removes toxins from the environment from the oil without the use of petrochemicals. Just because the bottle says fish oil does not mean it will be beneficial. The fish oil you purchase must be all natural and pure fish oil.

If you are in doubt about the supplement company that sells the product you buy, check for a Certificate of Analysis. This is an analysis conducted in a laboratory that says the ingredients contained in supplements are pure. Normally the manufacturer that can produce a Certificate of Analysis has taken precautions to ensure their product is pure and free of contaminants.
