Astaxanthin, also known as astaxanthin and lobster shell pigment, is a carotenoid and the highest grade product of carotenoid synthesis. It is dark pink and has a chemical structure similar to β-carotene. Beta-carotene, lutein, canthaxanthin, lycopene, etc. are all intermediate products of carotenoid synthesis. Therefore, in nature, astaxanthin has the strongest antioxidant properties. It is widely found in the biological world, especially in shrimp, crab, fish, algae, yeast and bird feathers. It is one of the main carotenoids in marine organisms.
ok of The Ancient Medicine of Abel, 1500 BC.The Ayurvedic texts describe the aphrodisiac effects of the herb.In ancient Egypt, fenugreek was used to relieve labor pains and other types of abdominal pain.
1. Protection of the eyes and central nervous system
The human retina and central nervous system (brain) are rich in unsaturated fatty acids. Therefore, free radicals generated by oxidation can easily cause peroxidative damage. Studies have shown that astaxanthin can easily pass through the blood-brain barrier and cell membranes, can effectively prevent oxidation of the retina and damage to photoreceptor cells, and protect the central nervous system, especially the brain, thereby effectively supplementing ischemia-re Perfusion injury, spinal cord injury, Parkinson’s syndrome, Alzheimer syndrome and other central nervous system injuries. In particular, the effect of retinal macular degeneration is more significant than that of lutein.
2. Suppress diabetic nephropathy
70% of diabetic patients will develop nephropathy damage within 5 years. Astaxanthin is the only substance found so far that can effectively prevent diabetic nephropathy. Astaxanthin mainly protects the glomerular basement membrane and prevents high blood sugar. 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, thereby preserving important substances such as ATP and sodium-potassium ATPase to ensure kidney blood Flow is not affected, reducing the production of proteinuria. In order to avoid urinary bubbles, diabetics must start using natural astaxanthin in advance. Studies have confirmed that 8 mg of astaxanthin can significantly reduce urine protein by 70% in 8 weeks.
3.Prevent cardiovascular disease
Clinical studies of arteriosclerosis and related cardiovascular diseases have shown that the oxidation of low-density lipoprotein (LDL) is an important cause of arteriosclerosis. The higher the concentration of LDL in the human body, and the thinning of blood vessels due to platelet deposition and obstructing blood flow, the greater the risk of atherosclerosis in the human body. The high-density lipoprotein (HDL) in the blood has the opposite effect, it can prevent the occurrence of arteriosclerosis. In vitro and clinical trials have proved that 3.6 mg/d astaxanthin per person can prevent LDL oxidation for 2 weeks. Different from general LDL lowering drugs, after taking 1.8, 3.6, 14.4, and 21.6 mg of astaxanthin daily for 2 weeks, the time of LDL oxidation was prolonged by 5.0%, 26.2%, 42.3%, and 30.7%, respectively; thereby preventing arteries The occurrence of atherosclerosis.
4.UV radiation protection
As we all know, ultraviolet radiation is an important cause of epidermal photoaging and skin cancer. Studies have shown that astaxanthin has a special effect on transglutaminase and 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 may make it a potential photoprotective agent, effectively scavenging free radicals that cause skin aging, protecting cell membranes and mitochondrial membranes from oxidative damage, and preventing skin photoaging.
Astaxanthin can significantly affect the immune function of animals. When antigens are present, it can significantly promote the ability of spleen cells to produce antibodies, enhance the role of T cells, and stimulate the production of immune globulin in the body. Astaxanthin has a strong activity of inducing cell division and has an important immunomodulatory effect.
6.Relieve sports fatigue and enhance body energy metabolism
Muscles release free radicals when the body exercises. If these free radicals are not processed in time by antioxidants, they will produce oxidative stress, causing muscle soreness or damage to muscle tissue. Studies have shown that astaxanthin can act as an antioxidant to inhibit the oxidative damage of free radicals to the body. In addition, oral astaxanthin can also strengthen aerobic metabolism, increase muscle strength and muscle tolerance, quickly relieve exercise fatigue, and reduce delayed muscle pain after strenuous exercise.
7.Anti-inflammatory and anti-infective properties
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 its oxidative damage to joints. Studies have shown that the inflammatory factors (such as prostaglandin E, etc.) inhibited by 4mg/day of astaxanthin are equivalent to 4mg [cortisone], but it does not have the side effects of the well-known [cortisone], so it is also known as Hormones without side effects.
Researchers have proposed the anti-cancer mechanism of astaxanthin, which is believed to be related to the stability of cell membranes and protein gene expression. By changing membrane stability and the number of gene expressions, it can regulate cell-to-cell communication, thereby improving the balance between cells and maintaining cells.
