Astaxanthin Supplier can be obtained by biological extraction, chemical synthesis, algae, bacteria and yeast. In addition, the construction of high-yield astaxanthin gene engineering by DNA recombination technology is also under study.

Astaxanthin is also known as Bitter Melon Extract and prawn yellow. In 1933, a kind of purplish red crystal was extracted from shrimp, crab and other aquatic products. It was determined that it was a carotenoid closely related to astaxanthin, so it was named astaxanthin. It is widely found in shrimp, Spirulina Protein Powder, birds, some algae and fungi. Astaxanthin, as a kind of non vitamin a carotenoid, can not be converted into vitamin A in animals, but it has the same antioxidant effect as carotenoid. Its ability to quench singlet oxygen and capture free radicals is more than 10 times higher than β - carotene and more than 100 times stronger than vitamin E. Citrus Aurantium Extract is also called "super vitamin E". Astaxanthin has been widely recognized for its antioxidant, pigmentation and immunity enhancing properties. The United States and other countries have been allowed to be used as food additives in production, as a natural food additive, has broad prospects for development.
