Astaxanthin is a carotenoid pigment and its antioxidant properties are thousands of times more potent than vitamin C. It’s one of the most powerful antioxidants out there, and it’s completely natural. In the same way that beta-carotene gives carrots their color, astaxanthin is responsible for the color of many of our favorite seafood and crustaceans. It gives sockeye salmon its color, and it’s found in krill, shrimp, crab, lobster, red trout and some algae. More and more researchers are homing in on the benefits of astaxanthin, and we are just in the beginning stages of uncovering its many uses. The benefits of antioxidants like astaxanthin extend to the cellular level, helping protect your body from the negative effects of free radicals, which many experts believe may lead to serious health concerns over time.
