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 supporting skin health, eye health, and reducing inflammation. Astaxanthin is often marketed as a dietary supplement, appealing to those looking to enhance their overall wellness and protect against cellular damage.
