What are astaxanthin good for?

Astaxanthin, also known as astaxanthin and lobster shell pigment, is widely found in nature. It was first found in the shells of shrimp and crabs. It is one of the main carotenoids in marine organisms and has strong antioxidant capacity. It is 500 times that of Vitamin E and is known as “Super Vitamin E”.
1. Antioxidant. Protect cells, lipids and membrane lipoproteins from oxidative damage by inhibiting lipid peroxidation.
2. Coloring. It specifically binds to myoglobin in the body, presents a bright red color and strong pigment deposition ability, and is a high-quality nutritional pigment.
3. Anti-inflammatory. Inhibit the expression of pro-inflammatory factors related genes, and reduce the activity of enzymes in the signaling pathway of inflammatory response.
4. Enhance the body’s immunity. Enhance the ability of T and B lymphocytes to proliferate and differentiate, increase the activity of natural killer cells, and increase the secretion of immunoglobulins.
5. Improve reproduction performance. In the process of animal reproduction, it can be used as a fertilized egg hormone to improve egg quality, protect the fertilized egg against harsh environments, promote egg maturity, reduce embryonic death, and improve reproductive capacity.

Ways to obtain astaxanthin in nature
1. Algae
Haematococcus pluvialis is recognized as the organism with the highest content of natural astaxanthin in algae, reaching 10-40 mg/g, and is currently the main algae producing astaxanthin. The structure of astaxanthin contained is mostly left-handed, with super biological activity, and is the best biological source of natural astaxanthin.
2. Fungi
Yeasts containing astaxanthin include Phaffia rhodozyma, Rhodotorula glutinosa, Rhodotorula crimosa and Rhodotorula marine. Rhodophaga is the first strain used to produce astaxanthin, and it is the most suitable microorganism for astaxanthin production besides Haematococcus pluvialis. The molecular configuration of astaxanthin is all right-handed and has partial antioxidant activity.
3. Aquatic products
The extraction and recovery of astaxanthin from the waste of aquatic product processing is also one of the ways to produce natural astaxanthin. However, this method has high cost, low extraction rate, high ash content, residual extraction solvents, and easy pollution. Generally, this extraction method The astaxanthin produced is only suitable for use as feed.

Synthetic
At present, the more extensive chemical synthesis methods of astaxanthin are as follows: ①15-carbon quaternary phosphonium salt method; ②C20+2C10 synthesis method; ③dimethyl astaxanthin conversion method; ④canthaxanthin conversion method.
In the synthesis of astaxanthin, left-handed (3S, 3’S): meso (3S, 3’R): right-handed (3R, 3’R) is 1:2:1. It has the advantages of low production cost and high output.

Astaxanthin current applications
At present, the extraction of astaxanthin from Haematococcus pluvialis is subject to cost constraints and is mainly used in human health products and cosmetics. Astaxanthin produced by Rhododendron is mostly used in feed and animal health industries. The effective content in commodities is relatively low, most of which are around 0.4%. Because of its molecular configuration, the absorption rate of animals is low and the cost-effectiveness is low. It should be noted that the difference in molecular configuration of astaxanthin is not equivalent to the pros and cons of biological potency. At present, there is no research showing that the biological activity of all-trans astaxanthin is better than the cis isomer. It is recommended that feed companies add synthetic astaxanthin with an astaxanthin content of more than 10%.
Kingsci Biotech has a Haematococcus pluvialis breeding base in Yunnan, which is pure natural extraction, high quality, and sufficient stock. In addition, KS supports third-party testing and has two warehouses in the United States to meet the needs of the North American market.
