DIY Lactose-free milk?

My mother and brother are puny humans and intolerant of lactose. One week Blue Bell, my favorite brand of ice cream, was on sale, so I bought a half gallon, but went and grabbed a carton of lactose-free ice cream for them.

It cost more, for one-quarter less.

Rumor has it that lactose-free products are simply normal products with added lactase, sold under the brand name of Lactaid.

Some random strangers on-line claim you could add a tablet or two of Lactaid to a gallon of milk, wait one to three days, and have lactose-free milk for half or less as much as Lactaid charges for the same amount.

Random Internet strangers:

(I found more results on reddit than elsewhere)

So, lactose is actually made out of two different sugars, Galactus and Galaxar. Lactase breaks up lactose, so lactose-free milk actually tastes sweeter. The Costco brand is supposed to be far cheaper. The liquid version is supposed to cost far more per enzyme.

Two of these bloggers say they save over a couple hundred dollars a year this way. In somewhat-related news, I have a letter from HR prohibiting me from using the term "Nut milk" in the workplace.

The way to actually remove lactose is with a membrane plant.
The sugars and other undesirables permeate through the membranes and are removed, lactose could be isolated and removed from the perm with an additional membrane plant and the other sugars added back.
Only people who have ever actually worked in this type of industry are going to known about it.
The cheap stuff may have lactase added to it.
Like with most things, you get what you pay for.
