This entry looks bad. "humens" is misspelled badly, the entry claims "most humans are lactose intolerant" which is misleading. FruitSalad4225 ( talk)

Labels on lactase bottles often differ to make comparison difficult. Here's a first stab at a table, which should eventually be posted to the main article.
It is more difficult to give an exact equivalence between milligrams (mg) and FCC units, but 125 mg should be sufficient as several companies list it as equal to 1750 FCC units.
-- Quest out of UK shows 2000 ALU per 200mg tablet of Lactase enzyme. — Preceding unsigned comment added by 41.220.239.226 ( talk) 17:51, 27 September 2020 (UTC)
I think sufficient detail should be placed to explain why β-galactosidase and lactase are not one in the same, as can be see we already had people making that confusion. It should be well explained that lactase is part of the family of β-galactosidase, that lactase is specific to lactose while other β-galactosidases is specific to one or many other galactosides. -- BerserkerBen 19:18, 22 December 2005 (UTC)
I don't, we don't need to explain the diffrence between beta galacticidase and lactase, but we do need ot explain that the missconception exist, and until you people talk out argeement with me in here instead of editing first I will fight it. Now as I stated before here is the solution I propose, state if you argee/disargee or what you want changed:
“Lactase is a beta galacticidase that can hydrolysis the beta 1,4 ether bridge of lactose”
and
“A common mistake is the assumption that all beta galacticidase enzymes are lactase enzymes, this is untrue as other beta galacticidases have substrates other then lactose.”-- BerserkerBen 02:23, 23 December 2005 (UTC)
http://www.drugs.com/pdr/LACTASE__BETA_D_GALACTOSIDASE_.html LACTASE (BETA-D-GALACTOSIDASE) http://www-saps.plantsci.cam.ac.uk/worksheets/scotland/milk.htm “lactase (ß galactosidase)” http://www.science-projects.com/LactaseTeacher.htm “β-galactosidase is also known as lactase” http://www.science-projects.com/LacInhibSetUp.htm “lactase, or β-galactosidase.” http://www.worthington-biochem.com/BG/default.html "Beta-galactosidase (Lactase)" Now I have a flight to catch so I'll be quick and get back to you later. Look I'm sorry to tell you this but wikipedia is meant for the general public (everyone), so misconception made by laymen need to be address to correct them. Now I have no problem with fixing grammatical, spelling, technical what ever errors, go crazy, but I will not stand for not address the problem I perceive, all I ask for is a sentence or two that addresses the fact the lactase is not beta-galactosidase, that lactase is specific to a reaction and only beta-galactosidases that can hydrolyses lactose can be called “lactase”. You can rewrite it in whatever why that you find is correct as long as you state the same premise. Now if you want this described under beta-galactosidases I’m fine with that to, just say you agree and we can be done with this. Now I’m very frustrated here, I thought we could discuss this agree upon a conclusion and then edit up the solution, but you people want to edit first and tell me to now that is just rude and makes a edit war mess in the history archives.-- BerserkerBen 18:14, 23 December 2005 (UTC)
Lactose intolerance figures can't be determined through simple genetics.
Lactose intolerance and lactase deficiency are not synonyms. Lactose intolerance is defined by the adverse symptoms that accompany a lactase deficient individual's consumption of lactose. Not all lactase deficient individuals ever have such symptoms, and thus not all lactase deficient individuals are lactose intolerant. Even if only 1/3 don't, the impressive propagandistic "75% of the world is lactose intolerant" straight-out-of-the-ass figure becomes 50%.
Lactose intolernace figures can't necessarily be determined through a simple survey or cursory diagnosis, especially in 3rd world countries.
Lactose intolerance is not the same thing as intolerance to cow milk, so any study you cite has to be able to positively differentiate them. Difficult, considering the symtoms are the same. Simple intolerance to cow milk is an allergy, totally unrelated to lactase abundance. Even if only 1/3 of those assumed to be lactose intolerant are actually intolerant to cow milk, the still passably impressive propagandistic 50% derived above becomes 33%.
If what the statistic means to say is that up to 75% of people are likely to develop lactose intolerance in their lifetimes, we have to ask what ages they are likely to develop it at. Is it really scientifically rigorous to say that a person who develops lactose intolerance on their death bed at age 84 should contribute to the statistic before that time?
Perhaps it means that up to 75% of people are at "significantly greater risk" towards contracting lactose intolerance? In which case, for the sake of perspective, please provide carcingen statistics in the same vein, so people can clearly see how utterly meaningless that really is.
Using similar vague terminology as that which is used to come up with the 75% figure, practically everyone in the world "has" cancer. -- 76.209.58.121 10:29, 27 February 2007 (UTC
Ummm... Most people ARE lactose intolerant. Try drinking an amount of milk proportional to what infants consume on a daily basis. Chance are pretty good you're gonna get diarrhea. Go on, try it. I dare you. What's "hilarious" is your overexcited response to a broad, generic statement. — Preceding unsigned comment added by 129.3.139.40 ( talk) 03:09, 2 March 2012 (UTC)
"Approximately 65 percent of the human population has a reduced ability to digest lactose after infancy." see https://ghr.nlm.nih.gov/condition/lactose-intolerance#statistics — Preceding unsigned comment added by Jphighwater ( talk • contribs) 23:32, 18 April 2016 (UTC)
In addition to the above responses which correctly reply that most human adults (and all other adult mammals) are lactose intolerant, the original comment about common cow milk intolerance being an allergy (IgE mediated) is wrong, and evinces a confusion about the mechanisms involved in allergies and lactose intolerance. — Preceding unsigned comment added by 2601:589:0:4B51:40F6:84D:6C36:E97F ( talk) 19:13, 17 April 2019 (UTC)
The article does not mention lactase in pill form (such as LactAid) that can be taken with a meal. Do these pills work? That is, in the stomach does lactase survive digestion long enough to do its job? Lactase is normally used commercially to break down lactose before the food item is eaten. An explanation of this would be helpful. -- Una Smith ( talk) 18:54, 11 December 2007 (UTC)

As this is so unfinished can I make a comment. In Germany Lactase is available in tablet form and has a strength number - the usual is 9000u. This means nothing to me, whether a strength for Lactase is relevant or not i have no idea. In the UK it's a health shop product and some are printed 3000 FCC but there's no way for a consumer to understand what that means. I am very intolerant of Lactose, even the tiniest amount (from a high fat product) causes symptoms so understanding what to buy, in what strength is important. — Preceding unsigned comment added by 5.67.226.44 ( talk) 09:15, 9 June 2015 (UTC)
Lactaid redirects to this page but it is not mentioned by this page. It would be useful to either provide a brief mention or restore the original page, since this seems like a notable pharmaceutical product to me. Dcoetzee 10:57, 5 July 2012 (UTC)
The stuff about breaking down lactose should be first, not the stuff about humans. 192.12.88.228 ( talk) 21:52, 23 April 2014 (UTC)
On March 3rd 2010 the page was edited so that the optimum temperature was set to 25 degrees Celcius. I cannot find support for this claim in the referenced publications, and already asked the corresponding user who edited the article for clarification. If you find the time, please check the referenced paper and, if possible, hint me at where the temperature optimum of 25 degrees Celcius is mentioned in it. Thank you C-Otto ( talk) 22:00, 9 October 2014 (UTC)
