Astaxanthin is by far the most powerful antioxidant found in nature, and its antioxidant activity far exceeds that of existing antioxidants. The introduction of astaxanthin has revolutionized the antioxidant market, and some even say that the 21st century is the century of antioxidants. Astaxanthin and its extracts from natural algae have been widely used in developed countries such as Europe, America and Japan. There are still very few people who know about astaxanthin in China. China is still only known to a few people in the scientific community and fashion beauty industry.
Global health products companies have also launched more than 200 astaxanthin soft, hard capsules, oral liquid health foods. Especially in Japan, the longest-lived country, it is the most popular. In the past three years, astaxanthin has become Japan's hottest health food. Southeast Asia, including Taiwan and Singapore, is deeply affected.
The health benefits of astaxanthin:
1. Ultraviolet radiation is an important cause of epidermal photoaging and skin cancer. Studies have shown that astaxanthin has a special effect on glutamine transaminase, which can consume putrescine when the skin is exposed to light. Oral astaxanthin has a stronger inhibitory effect on the accumulation of putrescine than oral vitamin A. Therefore, the strong antioxidant properties of astaxanthin make it a potential photoprotective agent, effectively removing free radicals that cause skin aging, protecting cell membranes and mitochondrial membranes from oxidative damage, and preventing skin photoaging.
2. Astaxanthin can significantly affect the immune function of animals. In the presence of antigen, it can significantly promote the ability of spleen cells to produce antibodies, enhance the role of T cells, and stimulate the production of immunoglobulin in vivo. Astaxanthin can also partially restore the humoral immune system of aged mice. In addition, astaxanthin can also enhance the ability of mice to release interleukin-Iα and tumor necrosis factor alpha, which is stronger than β-carotene and canthaxanthin. Much more. Therefore, astaxanthin has a strong activity of inducing cell division and has an important immunomodulatory effect.
3. Joint pain and arthritis are usually caused by oxidative damage caused by free radicals. The strong antioxidant properties of astaxanthin help to inhibit free radicals and reduce their oxidative damage to joints. Studies have shown that feeding mice with astaxanthin-rich Haematococcus pluvialis can activate the response of T lymphocytes, thereby reducing the adhesion and infection of Helicobacter pylori to the stomach. Mara studied the effects of erythromycin astaxanthin (astafactor) on human health and compared it with 26 other well-known anti-inflammatory drugs. The results showed that the health of patients taking astaxanthin increased by 85%. Anthocyanin has the same effect or effect as 92% of anti-inflammatory drugs.
4. Studies have shown that astaxanthin can act as an antioxidant to inhibit the oxidative damage of free radicals to the body. Oral astaxanthin can also strengthen aerobic metabolism, increase muscle strength and muscle tolerance, quickly relieve exercise fatigue, and reduce delayed muscle pain caused by strenuous exercise.
5. The human retina and the central nervous system (brain) are rich in unsaturated fatty acids, so free radicals generated by oxidation can easily cause peroxidative damage. Studies have shown that astaxanthin easily passes through the blood-brain barrier and cell membrane, which can effectively prevent retinal oxidation and photoreceptor cell damage, as well as protect the central nervous system, especially the brain, thereby effectively treating ischemia-re Central nervous system damage such as perfusion injury, spinal cord injury, Parkinson's syndrome, Alzheimer syndrome. In particular, the effect of macular degeneration is more pronounced than lutein.
6. Astaxanthin can reduce the oxidation of apolipoprotein and can be used to prevent arteriosclerosis, coronary heart disease and ischemic brain damage. Unlike conventional LDL-lowering drugs, LDL oxidation was prolonged by 5.0%, 26.2%, 42.3%, and 30.7%, respectively, after taking 1.8, 3.6, 14.4, and 21.6 mg of astaxanthin for 2 weeks; The occurrence of atherosclerosis.
7. 70% of people with diabetes develop nephropathy within 5 years. Astaxanthin is the only substance discovered so far that can effectively prevent diabetic nephropathy. Astaxanthin mainly protects the glomerular basement membrane and prevents the production of hyperglycemia. Free radicals to destroy the basement membrane; in addition, it can also fight free radicals in renal tubular epithelial cells, protect the normal transport of glucose and phosphorus in renal tubular cells, thus preserving important substances such as ATP and sodium-potassium ATPase to ensure kidney blood. The flow is not affected.
8. Studies by Tanaka et al. showed that feeding rats and mice with astaxanthin 100-500 mg/kg significantly inhibited chemical-induced initial carcinogenesis, and had anti-proliferative effects and enhanced immunity against epithelial cells exposed to carcinogens. The role of function, and this effect has a dose-effect relationship. Compared with the control group, the tumor incidence and tumor size in the high-dose group (500 mg/kg) were significantly lower than those in the control group and the low-dose group. Therefore, it is speculated that astaxanthin has significant anticancer properties. Astaxanthin can also induce transferase in the liver, significantly inhibiting mouse bladder cancer, rat oral cancer, colon cancer, and gastric cancer, and its effect is more obvious than that of β-carotene. In addition, astaxanthin can prevent the carcinogenicity of aflatoxin and has a good effect on reducing the amount and volume of aflatoxin-induced liver tumor cells.
