Astaxanthin is a carotenoid made by plants and algae, and found in marine seafood such as salmon. This carotenoid is also available as a food supplement either by itself or combined with other carotenoids.
Astaxanthin is a naturally occurring carotenoid that is closely related to beta-carotene and Lutein. Because of its unique structure, it provides a wide range of antioxidant benefits. It may play a role in the protection of cell membranes against free radical attack. It is a natural concentrate of marine algae Haematococcus pulvialis, which is cultivated in the warm waters of Hawaii. Recent studies have indicated that astaxanthin is more powerful than its carotenoid cousin, beta-carotene, at trapping singlet oxygen free radicals.
An investigation was done on the effect of three-month astaxanthin (Astaxin) supplementation on lipid peroxidation in healthy non-smoking Finnish men, aged 19-33 years. The intervention group received two 4-mg capsules daily. Supplementation decreased in vivo oxidation of fatty acids in healthy men.
Efficacy of the natural antioxidant astaxanthin in the treatment of functional dyspepsia in patients with or without Helicobacter pylori infection: A prospective, randomized, double blind, and placebo-controlled study.
Phytomedicine. 2008.
Patients with functional dyspepsia were divided into three groups with 44 individuals in each group (placebo, 16mg, or 40mg astaxanthin, respectively). No curative effect was found in functional dyspepsia patients. Significantly greater reduction of reflux symptoms were detected in patients treated with the highest dose. The response was more pronounced in H. pylori-infected patients.
It is obviously that astaxanthin supplements benefits human health.
