Enzyme that breaks down lactose into glucose and galactose

We rank Lactase by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.

What it is

Lactase is an enzyme, which is a type of protein that acts as a biological catalyst to speed up chemical reactions in the body. Specifically, it is the substance responsible for breaking down lactose, the sugar found in milk, into two simpler sugars called glucose and galactose.

Why it's used

It is used by people who are lactose intolerant, meaning their bodies do not produce enough of the enzyme naturally to digest dairy. By taking a supplement, users can break down the milk sugars before they reach the colon, which helps prevent common digestive issues like bloating, gas, and stomach pain.

How it's made

To produce this supplement commercially, companies typically grow specific types of fungi or yeast in large tanks. These microorganisms naturally produce the enzyme as they grow, and the lactase is then extracted, purified, and dried into a powder to be put into tablets or capsules.

What it typically costs

This ingredient is generally mid-range in price. This is because the fermentation process used to grow the enzymes requires controlled laboratory environments and specialized equipment, making it more complex to produce than basic minerals but cheaper than rare botanical extracts.
