Fight free radicals with astaxanthin, one of nature’s best antioxidants. Astaxanthin has a unique molecular structure that makes it very efficient at neutralizing free radicals throughout the body. Astaxanthin reviews suggest the supplement may be beneficial for cardiovascular health, immune health and healthy aging. As a naturally-occurring carotenoid, it’s also responsible for the red or pinkish color of salmon meat, as well as the red color of many cooked shellfish. Krill, the small shrimp-like crustacean, and the microalgae Haematococcus pluvialis are two of the most common sources used to produce astaxanthin supplements like our High Potency Astaxanthin formula from Swanson Ultra, our premier line of cutting-edge formulations that embrace the latest scientific breakthroughs.
