EPA5 / DHA72 Refined fish oil

The main ingredient in deep-sea fish oil is omega-3, also known as Omega 3, a polyunsaturated fatty acid that comes in two main forms: TG EE.

The full name for TG was triglyceride, which translates as "triglyceride."

The full name of EE is ethyl esters, which translates to "ethyl ester."

That is, TG fish oil = triglyceride fish oil = natural fish oil

EE fish oil = ethyl fish oil = synthetic fish oil

Fish oil ethyl esterification can improve the purity content, but it is easy to be absorbed by human body, is unstable easy to be oxidized. The purity of TG natural fish oil is slightly lower, but the absorption rate is at least three times that of EE synthetic fish oil. More informally, you can think of EE TG as trucks; EE has a large cargo capacity, but things are difficult to unload ( easy to absorb); TG has a small cargo capacity, the goods are easy to unload (easily absorbed by the human body).

Triglycerides are the natural molecular form of fat found in most foods. For example, Omega-3 unsaturated fatty acids are found as TG in fish.The main lipase in human pancreas liver hydrolyzes triglyceride exclusively cannot hydrolyze ethyl ester effectively to release free fatty acids for absorption by the body. After the hydrolysis of triglyceride type fish oil, the glycerol monoester is produced, which contributes to the reorganization of triglycerides.

Since there is no glycerol monoester in the hydrolysate of ethyl fish oil, it is necessary to obtain glycerol monoester substrate other ways, which delays the reaction of its free fish oil recombination into triglyceride. Free fish oil other unsaturated fatty acids will gradually be enriched oxidized, causing oxidative pressure to human body harmful to health. After being absorbed, ethyl fish oil is decomposed into ethyl ester in the gastrointestinal tract. People with poor tolerance to ethyl ester are prone to adverse reactions such as allergy, especially children. In addition, long-term consumption is easy to cause the lack of glycerin in human body lack of easy to cause the imbalance of sugar metabolism in human body produce side effects.

Few products will be marked on the package is TG EE type fish oil, consumers need to carefully read the label instructions, as the breakdown list. The EPA: DHA ratio of most TG fish oils is close to 3:2.

TG fish oils are easy to absorb but generally low in Omega-3. So the really good fish oil is the TG type high in Omega-3. Is there such a fish oil? Yes, but there are few on the market the price is relatively high. Langhee fish oil is a natural type of TG fish oil, with Omega-3 purity of up to 60-65%.
