Astaxanthin have beneficial effects supporting human health and well-being and by preventing pathologies. Significant antioxidant powers have been ascribed to astaxanthin, based primarily on experimental findings. In this context, human brain cells were subjected to an oxidative stress-induced neuronal cell damage system. Significant protection was found in cells pre-treated with astaxanthin. Additionally, pre-treatment with astaxanthin inhibited the generation of reactive oxygen species. The authors concluded the neuroprotective effect of astaxanthin is suggested to be dependent upon its antioxidant potential and mitochondria protection; therefore, it is strongly suggested that treatment with astaxanthin may be effective for oxidative stress-associated neurodegeneration and a potential candidate for natural brain food” [9]. Astaxanthin can also protect against damage from ischemia. The researchers attributed astaxanthin's benefits to its intense antioxidant activity [10]. Another study found that pretreatment with astaxanthin 5 h before ischemia provided protection against brain damage [
