Astaxanthin is an antioxidant carotenoid found in algae, yeast, salmon, shrimp, krill, and other kinds of fish and crustaceans. A brightly colored pigment, it gives salmon, cooked lobster, and flamingos their distinctive pink coloring. It is a powerful antioxidant with the unique ability to traverse the blood-brain barrier. Clinical trials indicate that astaxanthin improves the condition of the skin (including fine lines, wrinkles, elasticity, and moisture content), enhances recovery from exercise, relieves occasional indigestion, supports gastric health, helps maintain cholesterol levels already within a healthy range, enhances immune response, promotes healthy vision, and supports the male reproductive system.*
Astaxanthin is fat-soluble and is difficult to transport through the aqueous environment of the digestive system compared with molecules that are water-soluble. In fact, in vitro studies have shown that astaxanthin is virtually insoluble in gastric and intestinal fluids. Even in solubilized formulas, it quickly precipitates out once the saturation point is reached, making it hard for the body to absorb and utilize.
