Abstract :
Astaxanthin, whose the Haematococcus pluvalis as its richest source, is the strongest and the safest carotenoid without any pro-oxidant nature like ß-carotene, lycopene, zeaxanthin, and lutein. Astaxanthin has 550 times powerful than vitamin E and 40 times than ß-carotene as a singlet oxygen quencher, and 1000 times powerful than vitamin E against lipid perioxidation. It has superior position in cell membrane and shows 3 important triple effects: anti-oxidant, anti-inflammation, and immuno-modulator properties. Astaxanthin inhibits inflammatory gene expression by suppressing NF-kB activation, protects cells from oxidative stress, and then improvement of ß-cell function, insulin sensitivity and vascular complications (CVDs, etc), suppresses LDL-oxidation and may inhibit lipid peroxidation, and modulates endothelial NO system. In eye health, Astaxanthin reduces ciliary muscle strain during eye fatigue, and this may improve visual activity. Due to its strong antioxidant effects, astaxanthin may be of great important to reduce the risk for the development of ARMD. Due to its effect to quench free radicals and to lower lactic acid, astaxanthin enhances muscle endurance and physical fitness. Treatment of Helicobacter pylori infected mice with astaxanthin reduces gastric inflammation, bacterial load, and modulates cytokines release by splenocytes: a switch from a Th1-response to a mixed Th1/Th2 response during infection. Such an event is: a shift of the T-lymphocyte response from a predominant. Th1-response dominated by IFN-gamma is shifted toTh1/ Th2-response with IFN-gamma and IL-4. Treatment of H. pylori infected mice with astaxanthin decrease gastric inflammation, and bacterial load, and modulates cytokine release by splenocytes. Astaxanthin supplementation of men decreases lipid peroxidation (decreased 15 hydroxy fatty acid). Astaxanthin and a-tocopherol improve plaque stability by decreasing macrophage infiltration and apoptosis. Astaxanthin and vitamin C prevent gastric ulcerations in stressed rats. The role of antioxidant (Astaxanthin?) in carcinogenesis and chemoprevention in gastric cancer associated with H. pylori has been speculated. The intestinal absorption of astaxanthin delivered as capsules (4 mg bid) for 3 months is adequate and well tolerated, and decreases lipid peroxidation in healthy men
