Lactose Free Milk Brian's Best Organics


If you’re lactose intolerant, you may have switched to lactose-free milk in an attempt to avoid the unpleasant symptoms of gas, bloating, and diarrhea. However, some people have reported experiencing the same symptoms even when drinking lactose-free milk. In this article, we’ll explore why this happens and what you can do about it.

What is Lactose Intolerance?

Lactose intolerance is a condition in which the body is unable to digest lactose, a sugar found in milk and dairy products. This is due to a deficiency of lactase, the enzyme that breaks down lactose in the small intestine. When lactose is not properly digested, it passes into the large intestine where it can ferment and produce gas.

What is Lactose-Free Milk?

Lactose-free milk is cow’s milk that has been treated with lactase enzyme to break down the lactose into simpler sugars that are easier to digest. This makes it a good alternative for people who are lactose intolerant. However, lactose-free milk is not completely free of lactose. It still contains trace amounts of lactose that can cause symptoms in some people.

Why Does Lactose-Free Milk Cause Gas?

Even though lactose-free milk contains less lactose than regular milk, it still contains some lactose. This means that some lactose intolerant people may still experience symptoms after drinking it. Additionally, lactose-free milk is often made from skim or low-fat milk, which can be harder to digest than whole milk. This can also contribute to gas and bloating.

What Can You Do About It?

If you’re lactose intolerant and experience symptoms after drinking lactose-free milk, there are several things you can do. First, try switching to a different brand of lactose-free milk. Some brands may contain less lactose than others. You can also try drinking lactose-free milk in smaller amounts, or with food to help aid digestion.

Alternative Milk Options

If lactose-free milk still causes symptoms, there are several alternative milk options available. Soy milk, almond milk, and coconut milk are all lactose-free and can be good alternatives for people with lactose intolerance. However, it’s important to read the labels carefully as some brands may contain added sugars or other ingredients that can cause symptoms.


In conclusion, lactose-free milk is a good alternative for people with lactose intolerance, but it may still cause symptoms in some people. If you experience symptoms after drinking lactose-free milk, try switching brands or drinking it with food. If symptoms persist, consider trying alternative milk options. Remember to always read the labels carefully and consult with your doctor or a registered dietitian if you have any concerns.
