Hi all,

Below are items related to this article. I've rewritten it lately. To see the status of any new items check my website http://www.didgood.com/recipes/information/salmon/astaxanthin/astaxanthin.html

"Astaxanthin is not converted to vitamin A in the human body so it is completely nontoxic if given orally." - It will still be nontoxic, even if it was converted to Vitamin A. The process is regulated. Over-supplementation of beta carotene, for example, does not cause Hypervitaminosis A. — Preceding unsigned comment added by 69.124.116.101 (talk) 05:48, 3 January 2020 (UTC)

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.

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.

Relationship to Canthaxanthin

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.

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]

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]

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.

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.

[Anonymous]

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. [anonymous] 06:39, 13 August 2006 (UTC)

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)

BioReal changed its name to AstaReal. Astavita is one of AstaReal's retail brands - Astavita - USA - Haematococcus pluvialis

Perhaps mention Energy Recovery as a means of mitigating productions costs? [4]--Davagh (talk) 15:56, 3 November 2022 (UTC)

Tag of Copy Edit

The person tagging the article is correct. Anyone wishing to address the issue, feel free. meatclerk 04:57, 28 September 2006 (UTC)

==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)

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)

"A... In the Food Chain" Is the WORST segment i have ever read

Astaxanthin for Humans

I am not a qualified professional equipped to dialogue about this subject. Just thought since reading this reference material it suggests that Astaxanthin has been limited by the FDA (2009) to coloring of non-human animal food but I listened to a portion of a radio infomercial over this past weekend selling the product for human consumption by Puritans Pride under the name AFX I believe. Perhaps there is someone out there with the appropriate qualifications who is in a position to update this content if necessary. THX rlcawdrey@gmail.com — Preceding unsigned comment added by 173.58.179.6 (talk) 02:04, 12 June 2013 (UTC)

As written, the content for humans is vague and in need of better references. There is a body of human trial research on eye health, but unfortunately as of March 2016 it is all primary research, meaning no authoritative review, systemic review or meta-analysis. There is a small amount of trial results on skin health, but again, no secondary evaluation. As mentioned below, astaxanthin can be sold in the U.S. for human use as a dietary supplement ingredient. The FDA prohibition is specific for not allowing use as a food coloring agent if the intended consumer is human.

Three companies possess FDA-notified GRAS for astaxanthin in food (AstaReal [GRN #294], Innobio [GRN #580], and recently, Nippon Oil & Energy Corporation [GRN #700])(https://www.accessdata.fda.gov/scripts/fdcc/?set=GRASNotices&sort=GRN_No&order=DESC&startrow=1&type=basic&search=astaxanthin), and the FDA has also granted numerous notifications for supplement use (New Dietary Ingredient notifications.) — Preceding unsigned comment added by 27.52.10.86 (talk) 19:05, 21 July 2018 (UTC)

"Restricted to use in animal food" - why?

Natural astaxanthin is considered generally recognized as safe (GRAS) by the FDA,[10][11] but as a food coloring in the United States it is restricted to use in animal food.[12] 107.19.189.169 (talk) 03:02, 15 December 2014 (UTC)

GRAS status allows it to be used as a dietary supplement ingredient for humans. The FDA restriction applies to use as a food coloring agent = allowed for animals but not for humans. For example, feed for farm-raised salmon can contain astaxanthin to ensure a pink color to the resultant fish filets, salmon steaks or canned salmon. BUT, a manufacturer of canned salmon cannot add astaxanthin to the ingredients in the can if the contents are intended for human consumption (CAN be added to cans of salmon cat food).David notMD (talk) 16:32, 1 April 2016 (UTC)

GRAS permits food use and NDI permits supplement use - although it is not always needed if you have GRAS. See: http://www.nutritionaloutlook.com/regulatory/gras-vs-ndi — Preceding unsigned comment added by 27.52.10.86 (talk) 19:11, 21 July 2018 (UTC)

Best Isomer or Isomers for Human Consumption?

Which isomer(s) to buy for human consumption? Benefits, Price, Safety. ee1518 (talk) 13:11, 5 February 2015 (UTC)

various problems

Summary box - Other names - (3S,3'S)-Astaxanthin is listed twice. "Professor Basil Weedon's..." does not belong in that paragraph; suggest moving to end of first paragraph. Natural sources - "...and need not be hydrolyzed in the digestive tract of the fish." - what fish? "an important astaxanthin source in nature" does not make sense there. "than the cis isomer" - there is more than 1 cis isomer. "a leading fermentation production systems" - delete either a or the final s. Difference between natural and synthetic forms - Haematococcus should be capitalized. 69.72.92.124 (talk) 09:23, 25 December 2015 (UTC)
