Researches about antioxidant properties of astaxanthin

The astaxanthin is kind of widely used carotenoid, astaxanthin manufacturer conducted extensive studies about its antioxidant and anti-oxidation efficiency. Using blood cells in vitro to study the efficiency of several carotenoids exterminate the singlet oxygen, found that the lycopene’s effective is the best, the following is astaxanthin, β2 carotene is the worst. The efficiency of astaxanthin scavenging free radical is as good as angle zeaxanthin, and 50% higher than the β2-carotene, Clear hydrogen peroxide free radicals and prevent lipid peroxidation is significantly better than zeaxanthin, canthaxanthin and β2 carrots. Astaxanthin in the antioxidant process, each individual is not the strongest, but the capacity of antioxidant is the highest. Like vitamin E, astaxanthin is fat-soluble antioxidant, performance excellent oxidation resistance in the biofilm and lipid-rich tissues.

Human health is largely dependent on the body control free radicals, reduce the damage of oxidation to the organization of cells and DNA. Many human diseases and the aging process is associated with free radicals, although they are not the only factors of these diseases, but free radicals makes the body more sensitive to the pathogenic factors or inhibit the body's own defense and repair process, these diseases are more susceptible and exacerbate, these diseases are associated with free radicals: cancer, aging (including immunodeficiency and premature aging), inflammation (such as vasculitis, glomerulonephritis and autoimmune disease), Alzheimer's disease, Parkinson's disease, ataxia telangiectasia syndrome, emphysema, pneumoconiosis, arteriosclerosis, Keshan disease, myocardial disease, kidney transplant rejection, rheumatoid arthritis, pancreatitis, contact dermatitis, depending on age-related macular degeneration, retinal disease, radiation damage alcohol damage and other pollutants poison. A lot of experimental evidence show that astaxanthin can prevent age related macular degeneration and central nervous system diseases. Different from β2-carotene, astaxanthin easily through the blood-brain barrier.

The astaxanthin security, in many daily foods contain large quantities of astaxanthin farmed Atlantic salmon containing astaxanthin of 10 mg / kg, wild silver salmon containing an average of 14 mg / kg, a large red salmon, astaxanthin mass concentrations up to 40 mg / kg. People taking 316 mg / d, 712 mg of / d, 1414 mg / d dose of astaxanthin are no adverse reactions, and plasma LDL oxidation rate slow down with the increasing dose.

Application of astaxanthin, astaxanthin is a carotenoid, a brown-red crystals. Compared with β2-carotene and vitamin E, astaxanthin has a more biologically active hormone, can be used as cosmetic raw materials or pharmaceutical raw materials. Currently, the commodity astaxanthin mainly the chemical compounds, natural astaxanthin processing by haematococcus pluvialis, crustaceans, aquatic products and red yeast production. According to some market research studies show that: global carotenoids market volume in 1999 was approximately $ 786 million, $ 935 million in 2005, an average annual increase of 2.9, the biggest selling is carotenoids, astaxanthin and β2 carotene, they all account for 28% of the total sales volume. This shows that people are constantly know astaxanthin, accept the astaxanthin and enjoy the new opportunities of astaxanthin on human health. I believe, in the near future, there will be more and more people choose astaxanthin, a new era of anti-oxidation is opening.
