Talk:Fucus vesiculosus

Botanical names
We should use either the botanical (Latin) names or the common names & cross ref. Please decide which. I suggest the Latin names: Fucus vesiculosus not bladder wrack; Ascophyllum nodosum not Knotted wrack etc. There are others. Most seaweeds do not have common names - at least in English. Osborne 08:36, 30 April 2007 (UTC) Bladderwrack is the name most people go by. This isn't just a seaweed. It's a healing herb.

More biological information
There's an extreme shortage of biological information about this species. Half of the article is uncited information about its medical use. Zeldafanjtl (talk) 21:38, 28 October 2010 (UTC)

Vitamin B12
Yes, many vegans claim this seaweed (at various times classed as a plant, protozoa, blue-green algae, etc.). And yes, various and assorted studies have found cobamides in this seaweed and various and sundry plants, fungi, algae, etc. (barley malt syrup, shiitake mushrooms, parsley, sourdough bread, spirulina, nori, etc.) That said, the National Institutes of Health and various vegan groups confirm that there are no non-animal sources of dietary B12. None. Zero. Yes, you can find various analogs of B12 here, there and everywhere. That's nice. Using that in place of actual B12 might win you awards, but it won't prevent irreversible damage to your nervous system.

Let's leave it with Vegan Outreach: "Vitamin B12 is a complicated vitamin with a unique absorption mechanism and a number of inactive analogues (molecules that appear to be active B12, but actually are not) that possibly interfere with its function. Vitamin B12 is generally found in all animal foods (except honey). Contrary to the many rumors, there are no reliable, unfortified plant sources of vitamin B12, including tempeh, seaweeds, and organic produce." If you'd prefer a reliable source, the NIH says that "natural food sources of vitamin B12 are limited to foods that come from animals."

If you'd like to include a section on B12 here, we can certainly detail the vegetarian/vegan/raw vegan/fruitarian claims that this is a reliable source of B12, then clarify with the reliable sources that specifically and directly refute that claim, but it seems like a waste of space. Natural food sources of vitamin B12 are limited to foods that come from animals. - Sum mer PhD  (talk) 01:04, 2 December 2012 (UTC)

Allergic reaction to iodine
"Some people may suffer an allergic reaction to the iodine in bladder wrack"

Allergy to elemental iodine is theoretically impossible and even non-medical people should understand that, because our body needs iodine and there is NO way to avoid iodine. There is a section on allergy to iodine in the entry Iodine of Wikipedia.

Allergy to some iodine medical products such as contrast agents for X-rays is real, a true and life-threatening anaphylactic reaction but it is due to a component of the contrast agent that comes from a crustacian, not to the iodine. So when people display allergic reaction to bladder wrack, they are probably allergic to the chemical from the shrimp or prawn that shelter in the wrack.--Mirrordor 18:33, 8 September 2017 (UTC) — Preceding unsigned comment added by Mirrordor (talk • contribs)

With or without a space?
Should the compound be spelled bladderwrack or bladder wrack? The former is the one I'm more familiar with, and google n-grams suggests that since about the 80s it's the version about two or three times more common in print, both in BrEng and AmEng. As Google results, there are "about 779,000 results" (actually 192 nondups) for "bladderwrack" and "about 102,000 results" (actually 172 nondups) for "bladder wrack". Online dictionaries are not consistent. M-W and American Heritage require a space; vocabulary.com, The Century Dictionary, wordnet 3.0 require joined; The OED, Google, wordreference.com, dictionary.com, lexico.com accept either form. Collins defines spaced as the US spelling, joined as British. Wiktionary defines Bladder wrack as meaning either Fucus vesiculosus or Nereocystis luetkeana, and Bladderwrack as only Fucus vesiculosus. I'd personally advocate the more common usage to be used, but not sure it's important enough to edit. DewiMorgan (talk) 22:04, 14 December 2019 (UTC)
