DNA Lactose Intolerance Test

Find out if your digestive issues are due to lactose intolerance with this DNA test.



Lactose intolerance is a common occurrence in humans where 65% of the people around the world are lactose intolerance. People who are lactose intolerant are not able to break down the milk sugar lactose, because they are unable to produce the lactase enzyme.

Humans are born with the ability to make lactase. However, after weaning our ability to produce this enzyme gets reduced. Lactose sensitivity or intolerance there for is the rule. Some of us carry mutations that provide us with the ability to produce lactase well into adulthood. These “lactase persistent” individuals are able to digest lactose with no issues. The appearance of the mutation can be tracked back to communities that relied on dairy products as a dietary staple. When crops failed and food became scarce, people who could survive on passed on these advantages genetic changes to their children.

Uncover if you are at risk of developing lactose intolerance or whether your digestive symptoms are due to lactose intolerance with this DNA test.

Why should you take this test?

Once diagnosed, lactose intolerance can be easily managed by consuming lactose-free dairy products or by taking lactase tablets before consuming milk products. Alternative milk products supplemented with calcium and vitamins such as almond milk and soy milk are also widely available.

This test will also help you distinguish lactose sensitivity from other digestive problems caused by conditions such as Crohn’s disease or Celiac disease.

How common is lactose intolerance?

Your likelihood of developing lactose intolerance depends on your ethnicity. As mentioned already, development of lactose intolerance is a normal occurrence as humans develop into adulthood humans. However, some of us have inherited mutations associated with lactase persistence or the continued ability to produce lactase well into adulthood, which was retained because of the dietary reliance on dairy has a primary food source.

Many ethnicities are lactose intolerant
90% Asian-Americans
79% African-Americans
95-100% Native Americans
50% Mexican Americans

Only about 5% of people of Northern European ancestry and 25% of Caucasians are lactose intolerant.


Symptoms of lactose intolerance are caused by the excessive growth of gas-producing gut bacteria due to the buildup of undigested lactose.
• Bloating
• Flatulence
• Diarrhea
• Nausea
• Vomiting
• Abdominal pain or cramps
• Gurgling and rumbling sounds from the abdomen
