Mozzarella cheese is a popular ingredient loved worldwide, known for its creamy texture and meltability. Many people, especially those who are lactose intolerant, often wonder: Is mozzarella cheese lactose free? Understanding the lactose content in mozzarella can help you decide if it fits into your diet without causing digestive discomfort.
In this article, we will explore the lactose levels in mozzarella cheese, how it affects people with lactose intolerance, and tips for enjoying mozzarella safely. We will also cover alternatives and answer common questions related to mozzarella and lactose.

What is Lactose and Why Does It Matter?
Lactose is a natural sugar found in milk and dairy products. People who are lactose intolerant lack sufficient lactase enzyme to digest lactose properly, which can cause symptoms like bloating, gas, diarrhea, and stomach cramps after consuming dairy.
Because mozzarella is made from milk, it contains some lactose. But the amount varies depending on how the cheese is made and aged.
Is Mozzarella Cheese Lactose Free?
Mozzarella cheese is not completely lactose free, but it contains very low levels of lactose compared to fresh milk or cream. This is due to the cheesemaking process where much of the lactose is removed or broken down.
Fresh Mozzarella vs. Aged Mozzarella
- Fresh Mozzarella: This soft, moist cheese contains more lactose than aged cheeses because it’s not fermented or aged long enough for lactose to be fully broken down. It typically contains about 0.1 to 1 gram of lactose per ounce, which might still trigger symptoms in very sensitive individuals.
- Low-Moisture or Aged Mozzarella: The firmer, low-moisture mozzarella used for pizza or shredded topping is aged for a longer time, reducing lactose content further, often to nearly zero or trace amounts.
Lactose Content Comparison (Approximate)
| Dairy Product | Lactose Content (grams per 100g) |
| Whole Milk | 4.8 |
| Fresh Mozzarella | 0.5 – 1.0 |
| Low-moisture Mozzarella | 0.1 – 0.5 |
| Hard Cheeses (Cheddar, Parmesan) | <0.1 |
As shown, mozzarella contains significantly less lactose than milk but is not entirely lactose free.
Can People With Lactose Intolerance Eat Mozzarella Cheese?
Many lactose intolerant individuals can enjoy mozzarella cheese in moderate amounts without discomfort because of its low lactose content. However, sensitivity varies:
- Mild to moderate lactose intolerance: Likely safe to consume mozzarella, especially aged or low-moisture types.
- Severe lactose intolerance: May still experience symptoms from fresh mozzarella or larger quantities.
- Testing tolerance: It’s best to start with small amounts and monitor symptoms.
How Is Lactose Reduced in Mozzarella Cheese?
During cheese production, lactose reduction happens mainly through:
- Whey removal: Most lactose is found in whey, which is drained off during cheesemaking.
- Fermentation: Bacteria used in cheese aging convert lactose into lactic acid.
- Aging: Longer aging times allow more lactose to break down.
Mozzarella, especially the aged varieties, benefit from these processes but to a lesser extent than hard cheeses like Parmesan or Cheddar.
Lactose-Free Mozzarella Cheese Options
For those highly sensitive to lactose, there are lactose-free mozzarella cheeses available:
- These are made from milk treated with lactase enzyme to remove lactose.
- Some vegan mozzarella alternatives are entirely dairy-free and lactose-free, made from nuts or soy.
Frequently Asked Questions About Mozzarella and Lactose
Is fresh mozzarella safe for lactose intolerant people?
Fresh mozzarella contains more lactose than aged varieties but may still be tolerable in small amounts by some with mild lactose intolerance.
How can I reduce lactose symptoms when eating mozzarella?
Pair mozzarella with foods rich in fiber or probiotics, consume lactase supplements before eating, or choose aged/low-moisture mozzarella.
Is shredded mozzarella lower in lactose than fresh?
Yes, shredded mozzarella is usually made from low-moisture aged cheese, which has lower lactose content.
Are all cheeses low in lactose?
Most aged cheeses have very low lactose due to fermentation and aging, but fresh cheeses like ricotta, cream cheese, and fresh mozzarella have higher lactose levels.
Can lactose intolerant people eat pizza with mozzarella?
Most people with lactose intolerance tolerate the amount of mozzarella on pizza well, especially if it’s low-moisture mozzarella.
Mozzarella cheese is not completely lactose free, but it contains low levels of lactose that many lactose intolerant people can tolerate, especially when consuming aged or low-moisture versions. If you have lactose intolerance, starting with small amounts and observing your body’s response can help you enjoy mozzarella safely. For those with severe intolerance, lactose-free or vegan mozzarella options are great alternatives.
Enjoy your cheesy dishes without worry by choosing the right mozzarella and managing your lactose intake wisely!
