Marine Phytoplankton is able to detoxify themselves and the water around them to survive extreme conditions. Interesting enough, 60% of the human body is water. The two most relevant antioxidants of Marine Phytoplankton are carotenoids (pigments) and a certain group of enzymes named superoxide dismutase (SODs). 

β-carotene and Astaxanthine - both pigments - are known to be able to scavenge harmful oxygen and nitrogen radicals (13). Astaxanthine is 6000 times stronger than vitamin C when it comes to protecting against toxic reactive oxygen radicals (ROS) (14) (15) (16) (17). 

Superoxide Dismutase (SODs) - are the most important enzymes when it comes to protecting cells against these ROS (18). During the detoxification process, phytoplankton binds with minerals, making them an excellent source of vital minerals.
