Carotenoids, of which astaxanthin is a family member are a group of over 700 natural lipid-soluble pigments that are only produced by phytoplankton, algae, plants, and a limited number of fungi and bacteria. Carotenoids, and especially astaxanthin (asta-ZAN-thin), are distinguished by their capacity to interact with chemically reactive species of oxygen known as singlet oxygen and free radicals.
