Basic Info

What is Astaxanthin?

Astaxanthin is a ketone or carotenoid, pink in shade, fat-soluble, insoluble in water, soluble in organic solvents. It commonly exists in the organic world, especially in the feathers of aquatic pets such as shrimp, crab, fish and birds, as well as plays a role in shade growth. Astaxanthin is a carotenoid that is not a resource of vitamin An as well as can not be converted into vitamin A in animals. Astaxanthin is a fat-soluble as well as water-soluble pigment that exists in aquatic organisms such as shrimp, crab, salmon, as well as algae. The human body can not synthesize astaxanthin on its own. It is the strongest anti-oxidant in nature. Its antioxidant task is 550 times that of vitamin E and also 10 times that of β-carotene, so it is called “the king of antioxidants”!

Astaxanthin can be produced by certain algae, bacteria, and fungi. Some aquatic species, such as crustaceans including shrimp, eat these algae and plankton and store astaxanthin in their shells. These crustaceans are preyed on by fish (trout, salmon) and birds (ibis, flamingo) and store the pigment in their skin and fatty tissue. This is why the muscles, skin, feathers, etc. of animals such as salmon appear red.

Astaxanthin is distributed differently in different tissues and organs of different animals. The astaxanthin in the skin, eggs and scales of salmon is mainly in the esterified state, and the free astaxanthin is mainly distributed in the muscle, plasma and internal organs. The astaxanthin in the body of shrimp and the skin of sea carp is mainly esterified. Esterified astaxanthin is a more stable form of astaxanthin that is stored in the body without being oxidized. Haematococcus pluvialis is mainly esterified astaxanthin, which is recognized as the best organism in nature to produce natural astaxanthin.

Although natural astaxanthin exists in a variety of organisms, such as crab shells, shrimp shells, and red yeast, the content is very low, and the extraction process is complicated. In recent years, the extraction of astaxanthin from Haematococcus has developed rapidly, because Haematococcus grows fast and has a high concentration of astaxanthin. Most of the currently used astaxanthin is chemically synthesized.

Astaxanthin Uses

Astaxanthin has the functions of protecting skin and eyes, preventing cardiovascular aging, resisting radiation, preventing Alzheimer’s disease and cancer. The aging of the human body is mainly caused by oxidation caused by free radicals. Astaxanthin enters human cells, directly removes oxygen free radicals in cells, improves cell regeneration ability, and maintains normal human body functions.

Researchers have been developing new antioxidant substances: the first-generation antioxidant substances are vitamins; the second-generation antioxidant substances are β-carotene, SOD, coenzyme Q10, etc.; the third-generation antioxidant substances are anthocyanins , blueberry extract, grape seed extract, green tea, lycopene, lipoic acid, etc.; the fourth-generation antioxidant substance is natural astaxanthin. Studies have shown that the antioxidant activity of astaxanthin in Haematococcus pluvialis is much higher than that of β-carotene, grape seed extract, lipoic acid, lutein, and vitamin E.

Astaxanthin can significantly inhibit the initial carcinogenesis induced by chemical substances, and has the effect of inhibiting the proliferation and promoting immune function of epithelial cells exposed to carcinogens, such as inhibiting the growth of oral cancer, bladder cancer, colon cancer, breast cancer and gastric cancer cells. grow. Astaxanthin can also weaken the carcinogenicity of aflatoxin, and has a good inhibitory effect on aflatoxin-induced liver tumor cells.

Ultraviolet radiation is a crucial reason for epidermal photoaging and skin cancer cells. The solid antioxidant residential or commercial properties of astaxanthin can make it an efficient photoprotectant, get rid of complimentary radicals that cause skin aging, and secure cell membranes as well as mitochondrial membranes from oxidative damages. Protects against skin photoaging.

Studies have shown that astaxanthin can significantly increase HDL and reduce LDL in the body, in which HDL can be increased from the original 49.7mg/dL±3.6mg/dL to 66.5mg/dL +5.1mg/dL, so it is speculated that astaxanthin can Reducing the oxidation of apolipoprotein can be used to prevent coronary heart disease, arteriosclerosis and ischemic brain injury.

Astaxanthin can significantly affect the immune function of animals. In the presence of antigens, it can significantly improve the ability of spleen cells to produce antibodies, enhance the function of T cells, and stimulate the production of immunoglobulins in the body. Astaxanthin has a strong activity of inducing cell division and has important immune regulation function.

Astaxanthin can be used as an antioxidant to inhibit the oxidative damage of free radicals on the body. Oral astaxanthin can also strengthen aerobic metabolism, improve muscle strength and muscle tolerance, quickly relieve exercise fatigue, and reduce delayed muscle pain after strenuous exercise.

The Efficacy and Effect of Astaxanthin on the Skin

The efficacy and result of natural astaxanthin on the skin. Clean, white, and collagen-rich skin is the dream of every elegance fan. Nonetheless, as we grow older, the skin slowly ages, as well as places, wrinkles, sagging, as well as loss of Gloss, this will certainly make us overshadowed and also lose the charm and also confidence of young people.

The major factor for this scenario in the skin is oxidation, which generates oxygen free radicals as well as ruins our skin tissue. There are many reasons for the generation of free radicals. Ultraviolet radiation, smoking, alcohol addiction, keeping up late, air contamination, and so on will all produce oxygen free radicals, and also complimentary radicals will strike our cells, creating serious damages to our original cells. Some tissue structures will certainly be harmed, as well as a few of the above skin damages circumstances will certainly appear.

Synthetic and Natural Astaxanthin

  • Artificial
    Astaxanthin is the end point of carotenoid synthesis. B-carotene needs to add 2 hydroxyl groups as well as 2 ketone groups to exchange astaxanthin. Synthetic chemical synthesis is more difficult. Astaxanthin has 3 isomers, fives, 3’S, 3R-3’S, 3R, 3′ R (also known as left-handed, meso-, and also right-handed). Among them, the artificially synthesized astaxanthin is a mix of the three structures body with little antioxidant activity.
  • Biological origin
    All-natural astaxanthin primarily exists in algae, yeast, salmon, trout, shrimp, and so on. Astaxanthin from organic resources is risk-free to utilize, environmentally friendly, and has wide growth leads. At present, all-natural astaxanthin is mainly produced by microbial fermentation. Microbes with the ability of creating astaxanthin consist of: Phaffia spp. of the fungi Basidiomycetes, two pressures of germs that take in hydrocarbons, as well as environment-friendly algae that grow in a nitrogen-deficient setting.

    Haematococcus pluvialis is an important astaxanthin-producing bacterium. It is the most abundant astaxanthin-containing organism in nature. The astaxanthin content can reach 3.0% of the dry weight, accounting for about 90% of the total carotenoids. % above, known as the “concentrated product” of natural astaxanthin. Moreover, algal astaxanthin is 100% left-handed and has strong biological activity. The different growth environments of Haematococcus pluvialis will also affect the content of astaxanthin. For example, in an environment lacking nitrogen sources, astaxanthin can be accumulated in large quantities. In addition, Haematococcus pluvialis has strong viability, fast growth rate, high temperature resistance and easy outdoor cultivation, so it has great potential in the large-scale production process of astaxanthin.
