What is astaxanthin? Astaxanthin is one of many carotenoid pigments (along with beta-carotene, zeaxanthin, lutein, lycopene and others). Carotenoids lend color to the foods that contain them and may offer protective antioxidant benefits to those of us who consume them. Just as beta-carotene gives carrots their orange hue and lycopene contributes to the red color of tomatoes, astaxanthin is responsible for the vibrant color of krill, lobster, salmon, red snapper, algae, and many other ocean-dwellers. Astaxanthin is a bright shade of orange-red. An astaxanthin supplement provides a way to increase your intake of this potent antioxidant and fill in dietary nutrient gaps. These pigments have antioxidant effects, potentially helping our bodies fight free radicals. Some of them may have an affinity for specific areas of the body and others, like astaxanthin, promote health in multiple ways. Why choose Swanson Astaxanthin? Astaxanthin supports vision health when combined with other eye-supporting nutrients like lutein and zeaxanthin. Plus, the antioxidant carotenoid astaxanthin (along with omega-3 and omega-6 fatty acids) may play a central role in helping to protect against oxidative stress in the brain. The antioxidant benefits of astaxanthin shine when it comes to skin health as well, helping to combat to the skin from environ exposures.
