Astaxanthin, also known as astaxanthin and lobster shell pigment, is a carotenoid, and is the highest level of carotenoid synthesis products, dark pink, chemical structure similar to beta carotene.And -carotene, lutein, keratoflavin, lycopene and so on are the intermediate products of carotenoid synthesis, so in nature, astaxanthin has the strongest antioxidant.It is one of the main carotenoids in Marine organisms, especially in shrimp, crab, fish, alga, yeast and bird feathers.
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.Protective effects of the eye and central nervous system
The human retina and the central nervous system (brain) are rich in unsaturated fatty acids, so free radicals produced by oxidation can easily cause peroxidation damage.Research has shown that astaxanthin easily through the blood-brain barrier and cell membrane, can effectively prevent oxidation and the photoreceptor cells of the retina damage, as well as to the central nervous system, especially for the brain protection, thus effectively supplement ischemia-reperfusion injury, spinal cord injury, Parkinson’s, Alzheimer’s syndrome and other central nervous system injury.Macular degeneration was particularly more effective than lutein.
2.Inhibition of diabetic nephropathy
70% of diabetic patients will develop nephrotic damage within 5 years. Astaxanthin is the only substance found so far that can effectively prevent diabetic nephropathy. Astaxanthin mainly destroys basement membrane by directly protecting glomerular basement membrane and preventing free radicals produced by hyperglycemia.In addition, it can also fight against the free radicals of renal tubular epithelial cells, protect the normal transport of glucose and phosphorus in renal tubular cells, thereby preserving ATP and sodium-potassium ATPase, these important substances, to ensure that renal blood flow is not affected, reduce the production of proteinuria.Diabetics must start using natural astaxanthin in advance to avoid urine bubble events.Studies have shown that 8mg of astaxanthin can significantly reduce urinary protein by 70% over 8 weeks.
3.Prevention of cardiovascular disease
Clinical studies on arteriosclerosis and related cardiovascular diseases have shown that the oxidation of low-density lipoprotein (LDL) is an important cause of arteriosclerosis.The higher LDL levels in the body, coupled with plaque buildup that thins blood vessels and impedes blood flow, the greater the risk of atherosclerosis.High density lipoprotein (HDL) in the blood has the opposite effect, preventing atherosclerosis.In vitro and clinical trials have shown that astaxanthin, administered orally at 3.6 mg/d per person for 2 weeks, prevents LDL oxidation.Different from general LDL lowering drugs, the duration of LDL oxidation was increased by 5.0%, 26.2%, 42.3%, and 30.7% after taking 1.8, 3.6, 14.4, and 21.6mg astaxanthin daily for 2 weeks.Thus can prevent the occurrence of atherosclerosis.
It is well known that ultraviolet radiation is an important cause of skin photoaging and skin cancer.Studies have shown that astaxanthin has A special effect on transglutaminase, which can consume putriamine when the skin is exposed to light. Oral astaxanthin has A stronger inhibitory effect on putriamine accumulation than oral vitamin A.Therefore, astaxanthin’s strong antioxidant properties may make it a potential photoprotective agent, effectively scavenging free radicals that cause skin aging, and protecting cell membranes and mitochondrial membranes from oxidative damage, so as to prevent skin photoaging.
Astaxanthin can significantly affect the immune function of animals. In the presence of antigens, 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 the body.Astaxanthin has a strong activity of inducing cell division and plays an important role in immune regulation.
6.Alleviate exercise fatigue, enhance the body’s energy metabolism
When the body exercises, muscles release free radicals that, if not dealt with promptly by antioxidants, can cause oxidative stress, leading to 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 enhance aerobic metabolism, increase muscle strength and muscle endurance, quickly relieve exercise fatigue, 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 their oxidative damage to joints.Studies have shown that the inhibitory effect of 4mg/ day astaxanthin on inflammatory factors (such as prostaglandin E) is similar to that of 4mg [cortisone], but it does not have the side effects of [cortisone] that we are familiar with, so it is also known as a hormone without side effects.
Researchers have proposed the anticancer mechanism of astaxanthin, which is believed to be related to the stability of cell membrane and protein gene expression. By changing the stability of membrane and the amount of gene expression, the communication between cells can be regulated, so as to improve the balance ability between cells and maintain the normal function of cells.
How to differentiate astaxanthin
Astaxanthin from different sources has different stereoisomers and chemical composition.As the most natural source of astaxanthin, eutrochlorella is safe and highly absorbable.The purity and safety of astaxanthin derived from yeast and other fungi, chemical synthesis and waste from astaxanthin shell are low, which is not conducive to human absorption.
With scissors cut open the capsule rubber, good astaxanthin oil drops into a cup of clear water will quickly spread out, conducive to the full rapid absorption of the gastrointestinal tract.And inferior astaxanthin oil agent drops into clear water is a tuo black paste shape, cannot disperse, also go against absorption.The capsule skins of inferior products are usually opaque because artificial colors are used to cover defects in the rubber and contents.
If a soft astaxanthin capsule contains 4-5 milligrams of astaxanthin, the color of a capsule added to a kilogram of regular cooking oil is similar to that of fine salmon, which has 5 milligrams of astaxanthin per kilogram.
Matters needing attention
Natural astaxanthin should be used to reduce or stop smoking, staying up late, drinking and other bad habits, which will counteract its antioxidant effect.
If conditions permit, the changes of MDA and other lipid metabolites in urine can be examined to observe the effect of its use.
Because astaxanthin works by affecting and controlling oxidative damage in biological cells rather than specific organs, organ symptoms may not be obvious in some people.But the improvement in cell life was significant.
It may be better to use it externally and internally as a beauty treatment.
Patients with a handful of gall bladder dysfunction of fat-soluble vitamins E and shrimp green element such as the effect not beautiful, so after taking shrimp green reputation must check the color of the stool, if discover defecate color turn red after taking shrimp green reputation, it means the user prawn green poor digestion, absorption, recommended the water-soluble antioxidant such as vitamin C, etc.
