Japanese researchers say mice supplemented with the potent natural antioxidant astaxanthin appeared to burn fatty acids for fuel more efficiently, were able to exercise far longer, and had greatly decreased fat accumulation compared to mice that did not receive the compound.1
Previous research has shown that astaxanthin reduces oxidative damage from strenuous exercise in the skeletal and heart muscles of supplemented mice.2 Research also suggests that astaxanthin may improve human cardiovascular health and prevent cancer, among other potential benefits.3,4
Produced by certain marine algae, astaxanthin is a more potent antioxidant than other carotenes such as beta carotene.
