There are two methods -- chemical synthesis and natural extraction for the production of astaxanthin. When astaxanthin is synthesized by chemical means, impurity chemical substances, such as unnatural by-products produced during the synthesis process, will inevitably be introduced, which will reduce its bioavailability safety. Therefore, natural astaxanthin is favored.

Natural astaxanthin, due to different raw materials, the chemical structure of the extracted astaxanthin is also different, so the antioxidant capacity reflected is also different. The natural astaxanthin extracted from Haematococcus pluvialis has a 100% left-handed structure, with super strong antioxidant capacity, and the reflected biological efficacy is also super powerful. Astaxanthin derived from Phaffia yeast has a 100% dextrorotatory structure, and its antioxidant capacity is second; it is extracted from fish, shrimp, crab and other animals, and it is a mixture of three structures, its antioxidant capacity is the third, and finally it is artificially synthesized The astaxanthin has a 100% racemic structure, without any antioxidant capacity, and no longer has the biological efficacy that astaxanthin should have, so it can only be used as a chemical dye.

Sinoway can provide different astaxanthin according to your requirements. Please feel free to contact us.
