The main purpose of taking fish oil is to ingest Omega-3 DHA and EPA, which are important fatty acids that cannot be synthesized by the human body and are very important for maintaining physiological functions. The form of fish oil currently on the market often depends on the different extraction methods. Generally speaking, it can be divided into the following three types: TG type, EE type and rTG type:
TG type fish oil (Triglyceride form)TG type fish oil is the most traditional fish oil extraction mode. Natural fish fat mainly exists in the form of triglycerides. TG type fish oil is extracted from the subcutaneous fat of fish. After a basic refining process (including deodorization and solvent separation), the triglyceride form of fish oil is maintained as much as possible. Therefore, it is the closest to natural fish oil among the three types of fish oil.
Compared to the other two types of fish oil, the disadvantage of TG fish oil is that it has the lowest Omega-3 content, generally about 30~50%. However, because TG fish oil is closest to natural fish oil, it has better bioavailability in the human body, has the least processing steps, and is usually the lowest price.
EE fish oil (Ethyl Ester Form)Since the content of TG fish oil is relatively low, in order to increase the content of Omega-3 fatty acids in fish oil, the esterification technology was derived to achieve the purpose of concentration by separating the polyunsaturated fatty acids in the fish oil.
The Omega-3 content of EE type fish oil is about 50~70%. Due to the more complicated extraction technology, the price is higher. However, because EE type fish oil is not in the triglyceride form of natural fish oil, although the content is higher, the absorption rate is worse.
rTG fish oil (Re-esterified Triglyceride)rTG fish oil is an advanced version of EE fish oil, using more advanced extraction technology to achieve the following two purposes:
Generally, it can increase the Omega-3 fish oil content by >80%.
It also has the form of triglycerides, so the absorption rate is not compromised.
rTG fish oil is different from previous organic solvent extraction. It uses supercritical extraction and gas, so it can more completely preserve the nutritional value of fish oil. However, due to the high technical threshold, the purity and price of rTG fish oil are relatively high. Most of the fish oil on the market that claims to have a fish oil content of more than 80% is rTG fish oil. Regardless of its content or absorption rate, it is the highest. The only drawback is that it is more expensive.Details
Introduction of Omega-3 Fatty Acids
Omega-3 fatty acids help lower blood pressure, reduce the formation of triglycerides and vascular fatty plaques, and also help reduce the risk of cardiovascular diseases such as arrhythmia, heart disease, stroke and sudden cardiac death.
Nutritionists remind us that high triglycerides will increase the risk of heart disease, and long-term high low-density lipoprotein concentrations can also easily lead to cardiovascular disease. A Norwegian study pointed out that three groups of subjects took fatty acids with Omega-3 concentrations of 62.5%, 80%, and 85% respectively. The higher the Omega-3 concentration, the more obvious the decrease in the subjects' triglycerides and very low-density lipoprotein (VLDL).
There are many choices of fish oil products on the market. The basic difference between high and low concentrations is that if you take low-concentration fish oil, you need to take a larger dose to supplement the appropriate amount of Omega-3; however, high-concentration fish oil is relatively more efficient in supplementation. Because of its high purity, it is relatively less likely to ingest other additives that are not good for the body and cause extra burden on the body.
rTG extraction method: fish oil concentration, highest absorption rate
According to the extraction technology, fish oil can be divided into 3 types: rTG, TG, and EE; TG type has the lowest concentration, only 30%; EE type fish oil has a concentration of 50~70%, but the absorption rate of EE type fish oil is poor; rTG type fish oil has a concentration of up to 80%, and the absorption rate is also better. People can decide which product is more suitable for them according to their own needs.Details
Benefits of Fish oil With High Concentration
Timely supplementation of fish oil is one of the ways modern people regulate physiological functions. Fish oil, in particular, can improve heart and eye health, fight inflammation and depression, and improve children's hand-eye coordination and memory in the elderly. Although fish oil has many benefits, you still need to pay attention to three major issues, including concentration, supplementation time, and drug interactions, to avoid taking it without absorption and causing a burden on the body.
Supplementing enough fish oil every day has six major benefits for the human body, and can also reduce the incidence of cardiovascular disease, cancer, inflammation, autoimmune diseases and other diseases.
Effect 1: Maintain heart health
Fish oil can regulate cholesterol and triglyceride levels, increase good cholesterol and reduce triglycerides. It also helps lower blood pressure in patients with hypertension, prevent atherosclerosis, and reduce fatal arrhythmias.
Effect 2: Take care of eye health
Studies have shown that DHA in Omega-3 is one of the few nutrients that can affect the photoreceptor cells of the eyes. At the same time, it can increase the tear film breakup time and reduce tear osmotic pressure, reduce eye dryness and fatigue, and improve dry eye symptoms. In addition, if combined with other nutrients, it also has a positive effect on degenerative macular degeneration.
Effect 3: Helps relieve inflammatory diseases
Fish oil has anti-inflammatory properties, which can help relieve joint pain, stiffness and medication requirements in patients with rheumatoid arthritis, and reduce the production of inflammatory factors - cytokines.
Effect 4: Improves symptoms of depression
Depressed patients usually lack Omega-3 in their bodies, so timely supplementation of fish oil can alleviate depression symptoms. In fact, there have been international studies on the use of high-concentration fish oil as an auxiliary treatment for depression. Combining fish oil with antidepressant drugs as an enhanced treatment can help improve the effect. In addition, some studies have shown that fish oils with a higher ratio of EPA to DHA are better at alleviating depression.
Effect 5: Helps children grow and develop
Omega-3 is also very important for the early growth and development of infants. Supplementing with fish oil during pregnancy and breastfeeding can improve the baby's vision development and reduce the risk of allergies, and help the development of hand-eye coordination. In addition, fish oil has been shown to help reduce hyperactivity, inattention and other negative behaviors in children. Supplementing with fish oil can help children's life and learning to a certain extent.
Effect 6: Improve memory in the elderly
The human brain cells contain a large amount of DHA, which is an important component of nerve conduction and is related to brain functions such as memory. Studies have found that people who consume more oily fish such as salmon and tuna may experience slower brain function degeneration in old age. If they can supplement it in time, it can help the memory of the elderly.Details
