Astaxanthin, a naturally occurring carotenoid pigment, is renowned for its powerful antioxidant properties and the myriad of health benefits it offers. This potent molecule is what gives salmon, shrimp, and flamingos their distinctive pinkish-red hue, deriving primarily from microalgae that form the base of the aquatic food chain.
Astaxanthin is a keto-carotenoid that belongs to a larger class of phytochemicals known as terpenes. It is produced by the microalgae Haematococcus pluvialis when water supply dries up, protecting the algae from the damaging effects of sunlight and oxygen. In the wild, Astaxanthin is consumed by various marine creatures, leading to the vibrant colors observed in their flesh.
