Abstract
Astaxanthin is an antioxidant carotenoid abundant in the shells of crustaceans, salmon, trout, and other marine organisms. In both in vivo and in vitro experiments, astaxanthin has been proven to have a considerable impact on the neurological system. Astaxanthin exhibits these effects by modulating inflammation, suppressing oxidative stress, showing antioxidant effects, and suppressing neuronal apoptosis. In addition to its antioxidant, anti-inflammatory, and anti-apoptotic properties, astaxanthin has the potential to be used in the prophylaxis and treatment of neurological disorders due to its ability to cross the blood-brain barrier. Astaxanthin's commercial availability, lack of side effects, protective and therapeutic properties on the nervous system suggest that it may be a promising option in the future. In this review, information about the role of astaxanthin in the nervous system and its effects on neurological disorders are summarized.
