Is Zero Lactose Milk Dairy Free? Lactose-Free vs. Dairy-Free

Zero or lactose-free milk is not dairy-free. It is milk from which the lactose has been removed. Lactose is a sugar naturally found in milk and dairy products, and some people have trouble digesting it. This differs from a dairy allergy, which involves an immune response to proteins in milk, not lactose sugar.

On the other hand, dairy-free milk is made from plants such as soy, almonds, oats, or rice. These plant-based milk contain no dairy, so they’re safe for people with lactose intolerance and milk allergy.

So, if you’re lactose intolerant, lactose-free milk may be a good option for you. If you’re vegan or allergic to dairy, you’ll want to opt for dairy-free alternatives.

Zero Lactose Milk

Lactose-Free vs. Dairy-Free


Lactose-free products are derived from dairy but have had lactose (a type of sugar) removed. They are suitable for people with lactose intolerance who struggle to digest this sugar.

Dairy-free products do not contain any components of milk at all. They suit those with a milk allergy or those following a vegan diet.

Suitability for Dietary Needs

Lactose-free products are specifically for people with lactose intolerance. These individuals can digest dairy proteins but struggle with lactose due to a lack of the enzyme lactase.

Dairy-free products are designed for people who cannot consume dairy at all. This includes people with a milk allergy who react to proteins in milk and vegans who avoid animal-derived products.

Nutritional Profile

Lactose-free dairy products generally have a similar nutritional profile to regular dairy products. They contain the same amounts of protein, vitamins, and minerals.

Depending on their plant source, dairy-free products can vary widely in nutritional content. Some are fortified to match the nutritional profile of dairy milk, but others may lack certain nutrients found in dairy.

Taste and Texture

Lactose-free products usually have a taste and texture similar to regular dairy products since they are made from the same source.

Depending on the plant source, dairy-free products can have different taste and texture. For example, almond milk may have a nutty flavor, and oat milk may be creamier than other types.


Lactose-free products come from animals like cows or goats. The lactose is removed through a process involving the enzyme lactase.

Dairy-free products are made from a variety of plant sources, including nuts (like almonds or cashews), grains (like oats or rice), and legumes (like soy).

Digestive Enzymes

Lactose-free milk still contains the same proteins as regular milk. However, it has been treated with the enzyme lactase, which breaks down lactose into simpler sugars, glucose, and galactose, making it easier to digest for those with lactose intolerance.

Dairy-free milk doesn’t require the addition of enzymes for digestion because it doesn’t contain lactose or dairy proteins. However, the digestibility may depend on the individual and the specific type of plant milk, as some people may have sensitivities to certain plant proteins or fibers.

Environmental Impact

Lactose-free milk, an animal-derived product, has a similar environmental footprint as regular dairy milk. Dairy farming contributes to greenhouse gas emissions, land use, and water consumption.

Dairy-free milk typically has a lower environmental impact than dairy milk, as plant-based production usually requires less land and water and emits fewer greenhouse gases. However, the impact can vary depending on the crop and farming practices.


Lactose-free milk is often more expensive than regular milk because of the additional processing required to break down the lactose.

Dairy-free milk can also be more expensive than regular milk. The price can vary widely depending on the type of plant milk and the brand. Some specialty or organic plant-based milks can be quite pricey.
