Astaxanthin is a carotenoid with potent antioxidant activity and is said to be significantly more powerful than Vitamin E and beneficial for cardiovascular and immune health. Astaxanthin is found in microalgae, yeast, salmon, trout, krill, shrimp, crayfish, and crustaceans. Nutrient Innovations, Inc. carries Astaxanthin in powder form, ideal for powder encapsulation. This is a strong advantage for companies that specialize in dry powder encapsulation, who before might not have had access to quality Astaxanthin in powder form.
