Nutraceutical: Astaxanthin
Indication: Dementia
Source: Br J Nutr, January 2011;1-9.
Research: This study included 30 healthy volunteers between the ages of 50 and 69 years who were randomly assigned to receive either 6 mg or 12 mg of astaxanthin or 0 mg placebo every day for 12 weeks. Researchers wanted to investigate the effect of astaxanthin on phospholipid hydroperoxides (PLOOH), which are known to accumulate abnormally in the red blood cells of people with dementia.
Results: After 12 weeks of treatment, erythrocyte astaxanthin concentrations were higher in both the 6 and 12 mg astaxanthin groups than in the placebo group. In contrast, erythrocyte PLOOH concentrations were lower in the astaxanthin groups than in the placebo group. In the plasma, somewhat lower PLOOH levels were found after astaxanthin treatment. According to researchers, these results demonstrated that astaxanthin supplementation improved erythrocyte antioxidant status and decreased PLOOH levels, which may contribute to the prevention of dementia.
