Astaxanthin is a natural pigment belonging to the carotenoid family, primarily found in certain algae, shrimp, and fish like salmon. It is responsible for the pink and red colors in these organisms and plays a crucial role in their survival by providing protection against UV light and oxidative stress. This powerful antioxidant is known for its potential health benefits, including reducing inflammation and supporting skin health. Astaxanthin is often marketed as a dietary supplement, with claims that it may enhance athletic performance and improve eye health, although more research is needed to fully understand its effects.
