[edit] Pronunciation

The pronunciation was removed by another editor for an obscurely stated reason. I have restored taking under consideration that the word is neither in general use, nor likely to be pronounced correctly with the aid of a decent english class. Taken that and the fact the most people do not return to school after graduation it seemed only reasonable that a pronunciation was needed.


[edit] New Information to Merge

Yamaha Motor Expands Its Biotechnology Business, Centering on Astaxanthin July 6, 2005 - Found on Algaculture

Blue Goo and the Healthy Heart Aug 30, 2000 - Author has articles with unconfirmed sources of 700 stories for wired - 160 stories, largely from 2004, were reviewed of that 24 could not be verified. Dubious reporting

Since the information presented has no reference it will not be added immediately. The information seems mostly correct from previous investigations. However, in keeping with the article styel it will be merged once once references are found.

  • (should be true) Astaxanthin exhibits strong free radical scavenging activity and protects against lipid peroxidation and oxidative damage of LDL-cholesterol, cell membranes, cells, and tissues.
  • (is true) Research on the mode of action of antioxidants and astaxanthin, as well as their possible role(s) in oxidative stress, cancer, cardiovascular diseases, eye health, neurodegenerative diseases, aging, immune response, exercise, and animal health, is available.
  • (debatable) Astaxanthin has been the focus of a large and growing number of peer-reviewed scientific publications.
  • (debatable) Astaxanthin's biological properties, safety for humans, and possible applications for human health are available.

[edit] Relationship to Canthaxanthin

[edit] Natural vs. Synthetic

There is a basis for discussion here: http://algatech.com/astax.htm , but truely more research is needed. I've seen mention of this frequently, PubMed might be a good place too.

[edit] Astaxanthin in the food chain

  • In water
    • microalge
    • krill
    • shrimp
    • salmon
    • crab
  • On land
    • yeast
    • bird feathers
    • egg yolks

[edit] History

  1. Vitamin A
  2. Realization of Cartenoid
  3. First Found
  4. First Mapped

[edit] Dietary Notes

  1. Vegan
  2. Vegetarian
  3. Kosher
  4. Tahal
  5. Organic

Organic Certification allows the use of microalge, yeast or shrimp shells.[13] However, it is likely krill meal will be added to that list. It's exclusion is mostly likely production, logistic and/or managerial issues. [10]

[edit] Scrap

These scrap pieces that may or may not be used in the future. From previously deleted section,

  • In June 2003 natural astaxanthin was given novel foods approval in the EU for use as a dietary supplement[1].
  • Herbal Sciences International Ltd [2]

[edit] Canthaxanthin Interlinked

I removed the interlink for two reason.

  1. The article is inaccurate.
  2. This article is primarily about Astaxanthin, the regulations are footnotes. Linking to objects in footnotes creates technical and logistic difficulties.

[edit] Canthaxanthin Dispute

I've removed the following for several reason, but overwhelemingly #1.

  1. Canthaxanthin does not seem to be in use. Industry accountings talk about its disuse, not its use.
  2. The comment is in appropriate. The article is about Astaxanthin.
  3. I shall look into the accuracy of the government website. EU does ban its use.

UK law permits use of Astaxanthin with Canthaxanthin in poultry feed, salmon feed and trout feed. The Food Standards Agency also acknowledge this combination's links to deposition on the retina[3].

  1. Industry does use it, because it says it's in use on the food standards agency page.
  2. The comment is appropriate, it is clearly relevant as it is used in combination with it.
  3. There are no sources saying the EU bans it's use, but several saying it does not.--I'll bring the food 06:26, 13 August 2006 (UTC)
I will not participate in an edit war with you. I will ask an administrator to mediate.--I'll bring the food 06:26, 13 August 2006 (UTC)


I marked the canthaxanthin in disupte and promised to look into this..... what is this talk about an edit war??? If you are right I will update all my information. 06:39, 13 August 2006 (UTC)

[edit] Update

Apparently Bioreal has changed the name to Astavista, what a horrid choice. Anyway, I'll look into it. meatclerk 06:39, 13 August 2006 (UTC)

Astavita - Astavita - USA - Haematococcus pluvialis

[edit] ==Astaxanthin==

Thanks for your comment about my edit. It's the first I've received out of 300+ edits and is a breathe of fresh air. I try to stay within my abilities with full respect to those who have spent the great energy it takes to author. I found your article to be particularly well written and enjoyed reading it.Outlook 12:37, 29 September 2006 (UTC)

[edit] Tone concern on human use

It seems as though an IP user (74.233.44.246) has brought up an unclaimed source for negative side effects with beta-carotene and it's relation to astaxanthin. I will leave a tone tag in that section for someone whom might be able to present better content. --Specter01010 02:42, 18 October 2007 (UTC)

I removed the section on beta carotene since it was uncited. I re-wrote and monitor the article. Its addition was by an annoymous IP user, and seemed a non-specific allegation without merit. meatclerk (talk) 07:15, 27 April 2008 (UTC)
