At present, the most main natural astaxanthin powder on the market is extracted from Haematococcus Pluvialis, which accumulates astaxanthin in lipid vesicles in nutritional deficiency and harsh environments. Because Haematococcus Pluvialis tends to grow in places with strong sunlight, astaxanthin can protect the cell nucleus from the damage of free radicals generated by ultraviolet radiation. Natural astaxanthin has a unique molecular structure, making it hundreds of times stronger than any other antioxidant molecule.
Carotenoids are the general term for a class of natural pigments containing polyisoprene structures. They are commonly found in animals, higher plants, fungi and algae. And they are the main source of vitamin A obtained by the human body, and have functions of anti-oxidant, immune-regulated, and prevent Cardiovascular diseases, eye protection, etc.
Astaxanthin is a carotenoid and the highest grade product of carotenoid synthesis. It has a dark pink color and a chemical structure similar to β-carotene. Beta-carotene, lutein, canthaxanthin, lycopene, etc. are all intermediate products of carotenoid synthesis, so 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.
The antioxidant activity of natural astaxanthin exceeds all existing antioxidants. Its ability to scavenge free radicals is 6000 times that of vitamin C; 1000 times of vitamin E; 800 times of coenzyme Q10; 1800 times of nitric oxide; 3100 times of natto; 700 times of anthocyanins; β- 100 times of carotene; 10 times of Lycopene; 200 times of Lutein; 320 times of tea polyphenols; In addition, only algae, yeasts and bacteria can produce astaxanthin, and higher animals cannot transform this chemical structure. Natural astaxanthin also has a clear feature, it is the only carotenoid that can pass through the blood-brain barrier. Therefore, astaxanthin is well-deserved as the king of carotenoids.
