It belongs to a larger class of phytochemicals known as terpenes. It is classified as a xanthophyll, which means yellow leaves. Like many carotenoids, it is a colorful, fat/oil-soluble pigment. Astaxanthin can be found in microalgae, yeast, salmon, trout, krill, shrimp, crayfish, crustaceans, and the feathers of some birds. 12 Professor Basil Weedon was the first to map the structures of astaxanthin. Astaxanthin, unlike some carotenoids, does not convert to Vitamin A retinol in the human body. Too much Vitamin A is toxic for a human, but astaxanthin is not. However, it is a powerful antioxidant; it is 10 times more capable than other carotenoids.3 While astaxanthin is a natural nutritional component, it can be found as a food supplement. The supplement is intended for human, animal, and aquaculture consumption. The commercial production of astaxanthin comes from both natural and synthetic sources. The FDA approved astaxanthin See: Regulations below as a food coloring or color additive for specific uses in animal and fish foods3a. The European Union actually European Commission considers it food dye within the E number system, E161j3b.

Haematococcus pluvialis microalge Xanthophyllomyces dendrorhous, formerly Phaffia rhodozyma yeast Euphausia pacifica Pacific krill Euphausia superba Antarctic krill Pandalus borealis shrimp As a natural source, the following can be found in nature or a production facility with the approximate concentrations listed. Amounts of Astaxanthin Found in Food Natural Astaxanthin Sources Astaxanthin Concentrationppm Salmonids Plankton Krill Arctic shrimp Phaffia Yeast Haematococcus pluvialis ~ 5 ~ 60 ~ 120 ~ 1200 ~ 8000 ~40,000 Source: http://algatech.com/astax.htm With that, each source has its own production issues. Currently, the primary natural source for astaxanthin is haematococcus pluvialis microalge6. It seems to accumulate the highest levels of astaxanthin in nature4a; commercially more than 40 g of astaxanthin per kilo of dry biomass.4 It has the advantage of the population doubling every week, which means scaling up is not an issue; simply open another plant. However, it does require some expertise among the personnel and that might be its downfall. For Xanthophyllomyces dendrorhous yeast, interestingly enough it has similar advantages, but requires refrigeration once harvested above freezing, 6 degrees Celsius/43 degrees Fahrenheit. It also has the problem of being low in nutritional value, unlike krill or shrimp. Since it is not ocean-based, it has the issue of not carrying those ocean-like traits. Since its chief advantage is price, it will certainly be available for the cost-conscious consumer. For Euphausia superba krill, this report from aquafeed.com points to some of the issues: Krill Krill The Krill fishing operation is complex. It is done in Antarctic waters, under extreme weather conditions and far away from ports with substantial operational complexities. Krill's fishing location and the difficult weather conditions in the main fishing area, together with the costs involved in the operation, have contributed to a slow development of the industry. Krill fishing is by far different to any other fishing operation today known. The knowledge to work with it belongs to very few people in the world. P. borealis P. borealis Nonetheless as the article points out, producers still venture out. They include the Japanese, the Polish, the Russians, and Ukrainians. Lastly, krill will always have environmental issues, but being lower on the food chain allows it to reproduce more, and faster than larger ocean creatures-at least we hope. Pandalus Borealis shrimp might be seen as shrimp meat from the grocery store, or in a shrimp cocktail, or shrimp salad. Nutritious, tasty, and in danger of overfishing.17 Nonetheless, just the head and shell are used. That leads to this source having limitations one way or another.

It's definitely not in the literature, and the only information available is third-party. There are patents. There is one report of it being made from petrochemicals or petroleum. That said here is this: Today, essentially all commercial astaxanthin for aquaculture is produced synthetically from petrochemical sources, with an annual turnover of over $200 million, and a selling price of ~$2000 per kilo of pure astaxanthin. 4 Producers of Synthetic Astaxanthin Producers of Natural Astaxanthin Brand Name Producer Geographic Location Source AstaREAL Fuji Health Science Inc sub of Fuji USA Haematococcus pluvialis ECOTONE Acher Daniel Midland Illinois, USA Phaffia Rhodozyma Seeks Funding AlgaTech Israel Haematococcus pluvialis BioPrawns BioPrawns Norway Pandalus Borealis BioAstin Cyanotech Hawaii, USA Haematococcus pluvialis astaxanthin and Astafactor Mera Pharmaceuticals Hawaii, USA Haematococcus pluvialis - BioReal Inc. sub of Fuji Hawaii, USA Haematococcus pluvialis AstaCarox BioReal Sweden AB sub of Fuji Gustavsberg, Sweden Haematococcus pluvialis Parry's Natural Astaxanthin Parry Nutraceuticals Oonaiyur, India Haematococcus pluvialis Red-A Natural Astaxanthin Yunnan Green A Biological Project Co., LTD Yunnan, China Haematococcus pluvialis AQUASTA Tate and Lyle UK fermentation of carbohydrates dextrose - No website/Necton Portugal algae - No website/Sandypool Ltd.

Therefore, there are three stereoisomers; 3-R,3'-R, 3-R,3'-S meso, and 3-S,3'-S. Synthetic astaxanthin contains a mixture of the three, in approximately 1:2:1 proportions. Naturally occurring astaxanthin varies considerably from one organism to another. The astaxanthin in fish is of whatever stereoisomer the fish ingested.3c Uses In 1948, Nobel prizewinner George Wald surmized, This could lead to an important new use of astaxanthin as a drug delivery for medicines that are insoluble in water, and give designers of new food colourants or dyestuffs an interesting new capability.19 Astaxanthin is used as a feed supplement for salmon, crabs, shrimp, chickens and egg production4b. Regardless of the source, astaxanthin provides some important benefits beyond coloration. It also has been found to be essential for proper growth and survival.4 For seafood and animals The primary use of synthetic astaxanthin today is as an animal feed additive to impart coloration, this includes farm-raised salmon and egg yolks.4 In that, synthetic carotenoid i.e., coloured yellow, red or orange pigments represent about 15-25% of the cost of production of commercial salmon feed.4c Today, essentially all commercial astaxanthin for aquaculture is produced synthetically from petrochemical sources, with an annual turnover of over $200 million, and a selling price of ~$2000 per kilo of pure astaxanthin. 4 For humans Currently, the primary use for humans is as a food supplement. Research shows that due to astaxanthin's potent antioxidant activity, it may be beneficial in cardiovascular, immune, inflammatory and neurodegenerative diseases.9 Research supports the assumption that it protects body tissues from oxidative damage.57 It also crosses the blood-brain barrier, which makes it available to the eye, brain and central nervous system to alleviate oxidative stress that contributes to ocular, and neurodegenerative diseases such as glaucoma and Alzheimer's.8 The farm-raised salmon lawsuit The class action lawsuits were filed against some major grocery store chains for not clearly labeling the salmon color added.23 The chains follow up quickly by labeling all such salmon as color added. However, Smith Lowney persisted with the suit for damages, but a Seattle judge dismissed ...the case , ruling that enforcement of the applicable food laws was up to government and not individuals.24 Astaxanthin in the food chain It's been speculated that gulls are flushed pink when molting, especially in areas with farm-raised salmon.20 To say the least, this is intriguing. However, those speculating quite readily admit they don't know why. Even so, the bottom line is that not enough is known about the relationship between astaxanthin and plumage - they admit this as well. More research is need, as proposed by all.

Astaxanthin has 100-500 times the antioxidant capacity of Vitamin E and 10 times the antioxidant capacity of beta-carotene. Many laboratory studies also indicate astaxanthin is a stronger antioxidant than lutein, lycopene and tocotrienols.8 Only two 2 companies world-wide synthesize Astaxanthin.16 Synthetic astaxanthin fetches $2000 a kilogram on the market, while the natural product is sold for over $7000 a kilo.18 Salmon roe at the Shiogama seafood market in Japan Salmon roe at the Shiogama seafood market in Japan Salmon roes contain astaxanthin that gives them their reddish color and protects them from ultraviolet. It is believed that algae will expose its astaxanthin when the sun hits it, to protect itself. Flamingos can't make use of astaxanthin, so it goes to their feathers. Lobsters, shrimp, and some crabs turn red when cooked because the astaxanthin, which was bound to the protein, unwinds.21 Cardinals seem to produce astaxanthin from carotenoids when molting, even when fed primarily seed with natural yellow dye.22 While it constitutes a tiny portion of salmon feed 50 to 100 parts per million, astaxanthin represents a major share of the cost, up to 20 percent.23 References The references used in this article may be clearer with a different or consistent style of citation, footnoting, or external linking.
