Astaxanthin, also known as astaxanthin or lobster shell pigment, is a type of carotene and the highest level product of carotenoid synthesis. It is dark pink in color and has a chemical structure similar to β- Carotenoids. and β -  Carotenoids, lutein, keratin, lycopene, and other intermediate products in the synthesis of carotenoids, therefore astaxanthin has the strongest antioxidant activity in nature. Widely present in the biological world, especially in shrimp, crabs, fish, algae, yeast, and bird feathers, it is one of the main carotenoids in marine organisms.
The main health benefits of astaxanthin
Protective effects of the eye and central nervous system
The human retina and central nervous system (brain) are rich in unsaturated fatty acids, so the free radicals produced by oxidation are prone to oxidative damage. Studies have shown that astaxanthin can easily pass through the blood-brain barrier and cell membrane, effectively preventing retinal oxidation and photoreceptor cell damage, as well as protecting the central nervous system, especially the brain, thereby effectively supplementing central nervous system injuries such as ischemia-reperfusion injury, spinal cord injury, Parkinson's syndrome, Alzheimer's syndrome, etc. Especially, the effect of macular degeneration is more significant than that of lutein.
2 Inhibit diabetes nephropathy
70% of diabetic patients will develop renal damage within 5 years. Astaxanthin is the only substance found so far that can effectively prevent renal damage in diabetes. Astaxanthin mainly damages the basement membrane by directly protecting the glomerular basement membrane and preventing free radicals generated by hyperglycemia; In addition, it can also fight against 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, ensuring that renal blood flow is not affected, and reducing the production of proteinuria. In order to avoid the occurrence of urine bubbles in patients with diabetes, natural astaxanthin must be used in advance. Research has confirmed that 8mg astaxanthin can significantly reduce urinary protein by 70% over an 8-week period.
