What Is Lactase Enzyme?

  • By Josh

Published: Feb 19, 2026

Lactase is an enzyme produced in the small intestine. Its main job is to break down lactose (milk sugar) into two simpler sugars:

  • Glucose
  • Galactose

These smaller sugars are easily absorbed into the bloodstream and used by the body for energy.

 

When lactase levels are low, lactose remains undigested in the gut. This can lead to symptoms commonly associated with lactose intolerance.

How Lactase Works in the Body

Here’s a simple breakdown of how lactase enzyme functions:

  • You consume dairy (milk, cheese, ice cream, yogurt).
  • Lactose enters the small intestine.
  • Lactase enzyme splits lactose into glucose and galactose.
  • Your body absorbs these sugars for energy.

Without enough lactase, lactose travels to the colon undigested. There, gut bacteria ferment it—producing gas, bloating, and discomfort.

What Happens When You Don’t Have Enough Lactase?

When your body doesn’t produce sufficient lactase enzyme, it results in lactose intolerance.

Common symptoms include:

  • Bloating
  • Gas
  • Stomach cramps
  • Diarrhea
  • Nausea

Symptoms typically appear 30 minutes to 2 hours after consuming dairy.

Why Do Some People Have Low Lactase Levels?

There are several reasons why lactase production decreases:

 

1. Primary Lactase Deficiency

This is the most common type. Lactase production naturally declines after childhood.

 

2. Secondary Lactase Deficiency

This can happen due to:

  • Intestinal infections
  • Celiac disease
  • Inflammatory bowel disease
  • Gut injuries

3. Congenital Lactase Deficiency

A rare genetic condition where babies are born without the ability to produce lactase.

Is Lactase Enzyme the Same as Lactose Intolerance?

No. Lactase is the enzyme. Lactose intolerance is the condition caused by low levels of that enzyme.

 

Think of it this way:

  • Lactase = The tool
  • Lactose = The milk sugar
  • Lactose intolerance = What happens when the tool is missing

Can You Increase Lactase Enzyme Naturally?

Lactase levels are largely determined by genetics. However, you can manage symptoms by:

  • Taking lactase supplements before dairy consumption
  • Choosing lactose-free dairy products
  • Eating smaller portions of dairy
  • Pairing dairy with other foods

For many people, supplementing with lactase is the most convenient solution.

How Lactase Supplements Help

Lactase supplements provide the enzyme your body may not be producing enough of. When taken before consuming dairy, they help:

  • Break down lactose efficiently
  • Reduce bloating and gas
  • Prevent cramps and diarrhea
  • Improve overall digestive comfort

This allows you to enjoy dairy without the stress of discomfort.

Frequently Asked Questions

What is lactase enzyme responsible for?

Lactase enzyme breaks down lactose into glucose and galactose so the body can absorb and use it for energy.

Where is lactase enzyme produced?

It is produced in the lining of the small intestine.

What happens if you don’t have enough lactase?

Undigested lactose ferments in the colon, causing gas, bloating, cramps, and diarrhea.

Is lactase deficiency the same as lactose intolerance?

Yes. Lactose intolerance occurs when the body lacks sufficient lactase enzyme.

Can adults develop lactase deficiency later in life?

Yes. Many people experience a natural decline in lactase production as they age.

How quickly do lactose intolerance symptoms appear?

Symptoms usually appear 30 minutes to 2 hours after consuming dairy.

Are lactase supplements safe?

Yes, lactase supplements are generally considered safe for most people when used as directed.

Can children take lactase enzyme supplements?

In many cases, yes—but parents should consult a healthcare professional first.

Does yogurt require lactase enzyme?

Some yogurts contain live cultures that partially digest lactose, making them easier to tolerate.

Do lactose-free products contain lactase?

Yes. Lactose-free milk is treated with lactase enzyme to break down lactose before consumption.
