In chemical structure, ω-3 is a long chain composed of carbon atoms and hydrogen atoms (18 carbon atoms or more) with 3-6 unsaturated bonds (double bonds) between them. Because its first unsaturated bond is located on the third carbon atom at one end of methyl group, it is named ω-3.
The effective ingredient in fish oil is actually Omega-3 (composed of EPA and DHA). Add EPA and DHA to get the total content of Omega-3, and then compare it with the weight of the whole fish oil capsule to know the purity of fish oil.

ω-3 efficacy
1, promoting cardiovascular health
Omega-3 can reduce the contents of low-density lipoprotein "bad" cholesterol and triglyceride in blood and increase the content of high-density lipoprotein "good" cholesterol. It can also make blood vessels smoother, healthier and more elastic, and at the same time, it can reduce blood clots crowded with cholesterol and prevent the formation of blood clots that can block blood vessels.
However, by 20 18, the current evidence usually does not support the beneficial effect of ω-3 fatty acid supplements in preventing cardiovascular diseases (including myocardial infarction and sudden cardiac death) or stroke.
2. Relieve joint pain and discomfort
Omega-3 has anti-inflammatory effect, which can relieve swelling and pain and relieve the discomfort of arthritis. Clinical research has proved that it can relieve stiffness and discomfort in the morning, make joints less painful or swollen when touching, and reduce fatigue.
Step 3 eliminate migraine
Clinical studies have shown that ω-3 can help inhibit the secretion of "bad" prostaglandins that cause pain and inflammation. It can also reduce the viscosity of blood to promote blood circulation in the brain. This will reduce the number of migraine attacks, their severity and duration. Omega-3 is a nutritional supplement recommended by American Headache Foundation.
4, make the skin young and healthy
Omega-3 can keep skin balanced, moist and healthy. It can strengthen the delicate cell membrane around each cell, so that the cells can be fully nourished, and at the same time, it can effectively eliminate the waste in the cells.
It can make the dermis secrete more powerful collagen and elastic fibers, help eliminate wrinkles and fine lines, and tighten the gradually relaxed skin. Common skin problems caused by Omega-3 deficiency include rough skin, dense spots, chapped heels, eczema, psoriasis, acne, blackheads and hoary heads.
5. Reduce blood sugar and prevent diabetes.
Diabetic patients usually have higher triglycerides and lower high-concentration lipoprotein content, while omega-3 helps to reduce the contents of triglycerides and apoprotein, which are the "culprits" of diabetes, while increasing the content of high-concentration lipoprotein.
