message: This entry looks bad.  "humens" is misspelled badly, the entry claims "most humans are lactose intolerant" which is misleading.

: Well spelling is to be corrected not complained about (there is an edit button for a reason!), and I don't see what is misleading about most humans being lactose intolerant, please explain?

message: 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.
* 375 mg = 5,250 FCC units
* 200 LAC = ???
* 1 Lac. U. = 1 ALU = 1 FCC unit. 
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)

message: 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)

message: 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)

replies: text: The confusion here is that there are two types of EC numbers.  The number most relevant to this article is the Enzyme Commission number which is .  The second number, 232-864-1, refers to the European Commission system for coding chemicals, see EC-No. All the links that you have provided above point to the same CAS registry number . Boghog2 (talk) 04:42, 30 July 2009 (UTC)
replies: text:  Concerning food safety and EC numbers, Enzyme Commission number is not directly related to food safety, whereas the European Commission number function does relate to safety.  Hence adding a  tag to an Enzyme Commission number with the justification that it has to do with food safety makes no sense. Boghog2 (talk) 05:05, 30 July 2009 (UTC)

message: 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)
replies: text: According to Brenda, the temperature optimum for human lactase is 20 °C, but for a mutant enzyme.  The rat lactase optimum is listed at 25 while the E. coli optimum is claimed to be 37 °C.  Finally the referenced publication () didn't do a careful temperature dependence study, so their claim of 37 °C is suspect.  That is why I included the word "about".  We need a better reference.  This looks promising, but unfortunately Google books doesn't display all the pages (at least pages 84–85 are not displayed in my view) and I don't have access to a hard copy of the book.
