The role of astaxanthin In recent years, with people's understanding of health preservation, more and more people pay attention to the issue of anti-oxidation, so many people's health products must contain vitamin E, grape seeds, coenzyme Q 10 and so on. Some people are already familiar with astaxanthin as an antioxidant. It may still be a strange word in some people's eyes, and they don't understand the role of astaxanthin. Why do Japanese people live so long? Because they have salmon in their diet, and salmon contains astaxanthin. Astaxanthin is a carotenoid. It is also the highest level product of carotenoid synthesis. β-carotene, lutein, canthaxanthin and lycopene are only intermediate products of carotenoid synthesis, so astaxanthin has the strongest antioxidant capacity in nature. 1. Skin care: 1, sun protection: With its unique molecular structure, the absorption peak of astaxanthin is around 470nm, which is similar to the wavelength of UVA (380-420nm), so a small amount of astaxanthin can absorb a large amount of UVA, just like the most perfect and unique natural sunscreen on the earth, like a natural umbrella covering the whole body, which can be effective. In addition, it can quickly repair the skin burned by ultraviolet rays. Experts from the Rigano Institute of Dermatology in San Galle, Rome, came to the conclusion by taking photos. It is considered that astaxanthin has the best effect on preventing human epidermal fibroblasts from being damaged by ultraviolet rays. 2, freckle whitening: Astaxanthin can effectively inhibit the production of melanin up to 40% (when the content of astaxanthin in the skin reaches 10umol/L), and can significantly reduce the precipitation of melanin, so that you can stay away from dull, colorless and pigmented skin. Astaxanthin will make your skin more fair, beautiful, flawless and shiny. Its effect is far superior to arbutin, kojic acid, vitamin C and other whitening ingredients. So far, no substance has been found to have such a good effect of preventing melanin precipitation at the same concentration, so it is also known as the best raw material for whitening and freckle removal, and is used in high-end first-line cosmetics. Usually, when we make a mask, we can drop a drop of astaxanthin in the mask, and insist on using it will achieve good results. 3, anti-wrinkle: the skin is composed of epidermis, dermis and subcutaneous fat. The dermis contains collagen, elastin and other fibers, forming a skeleton that supports the skin. It is these elements that make the skin look smooth and young, and these elements are also easily affected by UVA, UVB, ozone or other oxidation factors. When the collagen in the dermis is oxidized and broken for the above reasons, the supporting effect on the epidermis disappears, which leads to uneven collapse of the epidermis, resulting in wrinkles, and the skin becomes dull, loose and dry, and wrinkles such as fine lines and crow's feet appear. Therefore, the fundamental reason to prevent skin from being oxidized is not to eat collagen. Some experimental data show that oral collagen is ineffective because its molecular weight is too large to be absorbed. The most fundamental way is to resist oxidation. Astaxanthin is the strongest antioxidant found so far. Second, health care: 1, diabetes: islet β cells are damaged, so insulin secretion is insufficient. Therefore, sulfonylureas are used to stimulate islet β cells to increase insulin secretion or supplement exogenous insulin in the treatment. The result of both actions is that islet cells are completely destroyed, which has always been questioned. In fact, 90% of diabetic patients or 2 hours after meals have higher insulin levels than normal people (10%). In fact, the onset of type 2 patients is not caused by the destruction of autoimmune β cells, but mainly by insulin resistance and insulin secretion disorder based on genetic defects. The most fundamental cause of insulin resistance and secretion disorder is oxidative stress. Oxidative stress is related to the occurrence, development, complications and deterioration of diabetes. Therefore, one way to solve oxidative stress is to use antioxidants such as astaxanthin and vitamin E in the early stage. 2. Gout: It is a well-known fact that the cause of gout is related to blood uric acid, but what causes the increase of uric acid and purine is unknown. Nucleic acid exists in any active cell in our body. In the process of continuous oxidative decomposition and replication, when the machine is attacked by free radicals or aging itself, RNA and DNA are oxidized and decomposed, resulting in a lot of waste. To put it bluntly, purine is the waste of DNA and RNA oxidation. So the root cause of gout lies in the oxidative decomposition of nucleic acid! Taking astaxanthin antioxidant can effectively inhibit the oxidative decomposition of nucleic acid and effectively prevent gout and hyperuricemia. 3. Dyslipidemia: Hypertriglyceridemia is the characteristic of dyslipidemia in China, which is mainly due to the remarkable changes in diet structure and lifestyle in 10 years. Dyslipidemia has become the biggest health hazard of China people. Appropriate intake of pheasant and duck egg yolk, roe and crab roe (rich in astaxanthin, etc. ) it's just beneficial and harmless. It can promote the increase of high density lipoprotein cholesterol (HDL) in human body, but it does not necessarily increase low density lipoprotein (LDL) or triglyceride. 4. Coronary heart disease: Coronary heart disease is called "the first killer of human health", and the incidence rate in China is increasing year by year, and it is younger. At present, the pathological basis of coronary heart disease is very clear, that is, subacute and non-infectious inflammatory reaction caused by excessive oxidative stress. Even in developed America, it is not enough to develop a modern emergency center for coronary heart disease. Patients must completely reverse atherosclerosis and eliminate the risk of myocardial infarction. Astaxanthin is a new product to prevent coronary heart disease, which was first used in Japan and the United States, because it is the strongest antioxidant and a good anti-inflammatory agent found so far, which can well target the pathogenesis of coronary heart disease, effectively inhibit the process of atherosclerosis and reverse atherosclerosis. 5. Hypertension: The real purpose of lowering blood pressure is to protect the small and medium arteries of important target organs such as heart, brain, kidney and eye, and prevent the blood vessels of these target organs from being damaged, leading to serious pathological changes such as myocardial infarction, cerebral infarction, renal failure and retinal hemorrhage. The antihypertensive western medicine can only play a temporary role in lowering blood pressure, and the speed of lowering blood pressure is faster, but all kinds of drugs will have certain side effects on the heart, brain, liver and kidney, so it is a big misunderstanding to temporarily lower blood pressure only by antihypertensive drugs. Astaxanthin mainly inhibits and reverses atherosclerosis through super antioxidant effect, so that foam cells gradually restore vascular smooth muscle cells, thus restoring vascular elasticity; Secondly, at the same time, the anti-inflammatory effect is used to prevent thrombosis from re-forming, and then the blocked collateral circulation is opened to expand the blood volume bin, thus continuously and slowly lowering blood pressure. 6. Cerebral infarction: Astaxanthin is a potential drug for the treatment of thrombosis, which can significantly reduce the probability of thrombosis and re-occlusion, and does not affect the coagulation function. Moreover, the recent X-ray diffraction technology clearly shows that astaxanthin can maintain the structure of cell membrane and show super antioxidant activity, while β -carotene interferes with the normal structure of cell membrane and shows extremely low antioxidant activity, which also explains why non-polar antioxidants such as β-carotene, vitamin E and vitamin C have not achieved clinical success. Third, feed: animals such as salmon and crayfish contain astaxanthin. The flesh color of some fish such as salmon is also the result of astaxanthin accumulation, but the astaxanthin in their bodies is not carried by themselves, but ingested through the food chain. Natural astaxanthin is extracted from Haematococcus pluvialis. The astaxanthin ingested by animals such as salmon and crayfish comes from algae. So, now someone is feeding fish, poultry and so on. Generally, natural astaxanthin is added as feed. In addition to their bright colors and better appearance, they also have extremely high nutritional value! The investigation report shows that people who take astaxanthin for a long time have obvious influence on it. In fact, from now on, people who have a better understanding of some diseases or human physiological functions will certainly understand the role of astaxanthin!
