Astaxanthin is a naturally occurring carotenoid that, because of its unique structure, provides a wide range of antioxidant benefits. Astaxanthin can help to protect cell membranes against free radical attack and potentiates the action of other antioxidants like Vitamins E and C. Scientific studies have demonstrated that Astaxanthin can help to support a healthy inflammatory and immune system response. Recent research indicates that Astaxanthin may even help to support the skin's structure during exposure to sunlight.*
