The Short Answer
An essential enzyme that helps you digest dairy products comfortably by breaking down milk sugar (lactose).
CategoryEnzyme
GroupEnzyme
Evidence LevelModerate
Synergy Pairings4
Health Benefits
Enables digestion of lactose into glucose and galactose for absorption
Alleviates symptoms of lactose intolerance such as bloating, gas, and diarrhea
Enhances nutrient uptake from dairy, including calcium and vitamin D
Promotes bone health by supporting efficient calcium utilization
Prevents fermentation of undigested lactose in the colon, maintaining gut comfort.
Origin & History
Lactase (EC 3.2.1.108), also known as β-galactosidase, is a digestive enzyme produced in the brush border of the small intestine. It catalyzes the hydrolysis of lactose, a disaccharide sugar found in dairy products, into its constituent monosaccharides, glucose and galactose. This enzymatic action is crucial for the proper digestion and absorption of dairy, particularly for individuals with lactose intolerance.
“While the enzyme itself is a modern biochemical discovery, traditional systems like Ayurveda emphasized 'digestive strength' (Agni) as crucial for assimilating foods like milk. The modern understanding of lactase provides a scientific basis for the historical observation that dairy tolerance varies among individuals and populations.”Traditional Medicine
Scientific Research
Extensive clinical trials and meta-analyses consistently confirm lactase's efficacy in reducing gastrointestinal symptoms associated with lactose intolerance. Research supports lactase enzyme supplementation as a safe and effective method for improving lactose digestion and enhancing the absorption of dairy-derived nutrients like calcium.
Preparation & Dosage
Common Forms
Available as capsules, tablets, or liquid drops, often in digestive enzyme blends.
Dosage
Typically 3,000–10,000 FCC lactase units per dose, taken with dairy-containing meals.
Timing
Consume immediately before or with the first bite of dairy products to ensure optimal efficacy.
Nutritional Profile
- Lactase (EC 3.2.1.108): The enzyme responsible for breaking down lactose.
- Lactose: The disaccharide substrate, a sugar found in milk and dairy products.
- Glucose and Galactose: The monosaccharide products of lactose hydrolysis, readily absorbed for energy and metabolic processes.

Frequently Asked Questions
What is lactase?
Lactase is a digestive enzyme that breaks down lactose, the sugar found in milk and dairy products, into simpler sugars that your body can easily absorb. Supplementing with lactase helps people with lactose intolerance digest dairy without discomfort.
How much lactase should I take?
A typical dose is between 3,000 and 9,000 FCC units, taken just before or with your first bite of a dairy-containing meal. The exact amount depends on your level of intolerance and the amount of lactose in the food.
Does taking lactase cure lactose intolerance?
No, lactase supplements do not cure lactose intolerance. They provide the enzyme your body lacks on a per-meal basis, allowing for comfortable digestion of that specific meal, but they do not permanently restore your body's ability to produce lactase.
