Human health is heavily dependent on the body to control free radicals, reduce oxidative tissue and DNA damage. Many human diseases and the aging process are related to free radicals, although they are not the only factor to these diseases, but the radicals makes the body more sensitive to the pathogenic factors or to inhibit the body's own defense and repair processes, so that these diseases are more susceptible and exacerbate these diseases are related to free radicals: cancer, aging (including immunodeficiency and premature aging), inflammation (such as vasculitis, glomerulonephritis and autoimmune disease), senile dementia, Parkinson's disease, ataxia telangiectasia syndrome, emphysema, pneumoconiosis, arteriosclerosis, Keshan disease, cardiomyopathy, renal transplant rejection, rheumatoid arthritis, pancreatitis, contact dermatitis, age-related macular degeneration, retinal disease, radiation damage, alcohol, injury and other pollutants being poisoned.

Research by astaxanthin suppliers has shown that astaxanthin can inhibit the occurrence of the mouse bladder cancer. Researchers used the carcinogen feeding mice 20 weeks, and then divided into two groups, one with add astaxanthin fed with the feed in the control group without astaxanthin feeding 20 weeks was made after histological examination, found that the control group the incidence of bladder cancer by 42 percent, while the astaxanthin diet group bladder cancer incidence rate was 18%, similar studies have shown that astaxanthin can also reduce the mouse oral cancer, rectal cancer, such as the incidence.

In vivo, in vitro animal experiments show that astaxanthin significantly affect immune function, promote antibody production of mouse spleen cells in vitro and human red blood cell immunoglobulin production. Experimental evidence that astaxanthin can prevent age-related macular degeneration and central nervous system diseases. Β2 carotene, astaxanthin is easy to pass the blood-brain barrier.

Many everyday foods contain large quantities of astaxanthin of farmed Atlantic salmon with astaxanthin, 4 to 10 mg / kg, the average wild coho salmon with astaxanthin 14 mg / kg of red salmon astaxanthin The mass concentration of up to 40 mg / kg. People were taking 316 mg of / d, 712mg / d, 1414 mg / d dose of astaxanthin pigment are no adverse reactions, and plasma LDL oxidation rate slowed down to increase with the dose. Pharmaceutical companies to conduct the following experiment: 33 healthy adult volunteers, daily doses of 3185 mg or 19 125 mg of natural astaxanthin (from rain pluvialis powder) for 29 days before the experiment, experimental, and experimental volunteers after a comprehensive physical examination, including weight, color, physical appearance, blood pressure, vision, color vision, depth perception, eye, ear, nose, mouth, throat, teeth, chest, lungs, urine analysis, blood analysis (blood cell count, hemoglobin, liver enzyme activity, etc.) and found no toxic side effects of astaxanthin. The results of other studies also show that astaxanthin is safe.

Astaxanthin is a carotenoid, crystal brown red. Compared with the β2-carotene and vitamin E, astaxanthin has a greater biological activity, can be widely used in feed, food, pharmaceutical and as cosmetic raw material. At present, commodity astaxanthin mainly chemical compounds, natural astaxanthin produced from rain pluvialis, crustaceans, aquatic products processing by-products extract and red yeast. According to the research shows that: the amount of global carotenoid market is about $ 786 million in 1999, $ 935 million in 2005, average annual growth rate of 2.9, the biggest-selling carotenoids astaxanthin and β2-carotene, each class carrot factors of total sales 28%. Thus, people are constantly understanding of astaxanthin, acceptance of astaxanthin and enjoy the astaxanthin on human health, brought a new opportunity. You can image that in the near future, there will be more and more people choose to astaxanthin, a new antioxidant.
