Astaxanthin
What is Astaxanthin?
Astaxanthin is a member of the carotenoid family, a class of more than 750 naturally occurring pigments synthesized by plants, algae, and bacteria. Astaxanthin is a red carotenoid pigment found in certain marine plants and animals. Sometimes called "the king of the carotenoids," it's packed with antioxidants that promote optimal health. For example, it may support healthy aging, especially for the heart and other important muscles, by helping to protect the body from the damages wrought by everyday exposure to environmental toxins, irritants, and stressors.
How Do Carotenoids Work?
Carotenoids can be divided into two main types: carotenes, which are composed of only carbon and hydrogen; and the xanthophylls, which are oxygenated derivatives. Astaxanthin is a xanthophyll carotenoid.
As mentioned above, many animals use carotenoids like astaxanthin for their nutritional benefits as well as their pigmentation. Animal coloration mainly results from metabolic transformation (oxidation and/or reduction) of the carotenoids present in their food.
The dark-red carotenoid pigment of astaxanthin can be found primarily in oceanic plant life, such as algae, as well as in certain marine animals. Astaxanthin is ingested in the human diet from certain types of seafood, and it is also available as a dietary supplement in various combinations with complementary ingredients.
Common Sources of Astaxanthin
The most common source of astaxanthin in the diet is from seafood. Astaxanthin can be found in crustaceans, including shrimp, crab, lobster, krill, and crawfish, as well as in fish with pink flesh, such as salmon or trout.Studies report that consumption of fish and seafood, or supplementation with fish oil or krill oil, provides the human body with crucial omega-3 long-chain polyunsaturated fatty acids known as EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), which may support a healthy immune system, cardiovascular system, and musculoskeletal system.
Common Uses for Astaxanthin
Astaxanthin is used in dietary supplementation to help maintain optimal health. It is used primarily in sports and fitness by athletes who claim astaxanthin supplements may promote athletic endurance and post-workout muscle recovery, supporting aspects of energy metabolism and athletic performance. In preliminary trials, astaxanthin supplements showed promise for use in supporting athletic performance, but further research is needed.
Also, in 1987, the U.S. Food and Drug Administration approved astaxanthin for use in feeding fish grown for human consumption, and in 1999, it was approved for use as a dietary supplement (also known as a nutraceutical).
