Antioxidant effect of astaxanthin on phospholipid peroxidation in human erythrocytes
Phospholipid hydroperoxides (PLOOH) accumulate abnormally in the erythrocytes of dementia patients, and dietary xanthophylls (polar carotenoids such as astaxanthin) are hypothesised to prevent the accumulation. In this study, both astaxanthin and PLOOH levels in the erythrocytes of thirty middle-aged and senior subjects were evaluated over 12 weeks of treatment. The study results suggests that astaxanthin supplementation results in improved erythrocyte antioxidant status and decreased PLOOH levels, which may contribute to the prevention of dementia.

Astaxanthin protects neuronal cells against oxidative damage and is a potent candidate for brain food
Astaxanthin (AST) is a powerful antioxidant (classified as a carotenoid) that occurs naturally in a wide variety of living organisms. The study results suggest that Astaxanthin is strongly recommended as part of a treatment for cognitive disorders based on its antioxidant potential and mitochondria protective properties. AST may be effective for oxidative stress-associated neurodegeneration and a potential candidate for natural brain food.

Macular DegenerationAstaxanthin and Macular Degeneration
In this study published in 2001, 145 patients with macular degeneration were randomly assigned to be given supplements of lutein (10mg), zeaxanthin (1mg) and astaxanthin (4mg). The results were evaluated after 1 and 2 years. Those people in the group receiving the antioxidants above showed significant improvement in visual acuity (ability to see more clearly). In addition, the researchers concluded that people given lutein, zeaxanthin and astaxanthin together with other nutrients were more likely to report significant improvements.

Computer Eye StrainAstaxanthin (2006 study) Reduces Eye Strain (Asthenopia)
A couple of randomized double blind placebo controlled pilot studies demonstrated the positive effects of supplementing with astaxanthin on visual function. In one study by Nagaki et al., (2002), it demonstrated that subjects (n=13) who received 5 mg astaxanthin per day for one month showed a 54% reduction of eye fatigue complaints.
In another study by Nakamura (2004), significant improvements were shown in reducing asthenopia and positive accommodation for the 4 mg (p<0.05) and 12 mg (p<0.01) groups. In re-evaluating the dosages in 2005 to 6 mg per day. the group improved significantly better at week 2 and 4 of the test period.
