Why does dairy bother you?

If you’ve ever experienced bloating, cramps, or discomfort after enjoying a dairy-rich meal, your genes might hold the answer. The DNA Lactose Intolerance Test uncovers the genetic reasons behind your body’s reaction to lactose.

With a quick and painless cheek swab, discover whether lactose intolerance is in your DNA, so you can plan meals that work for your body.

Decode the science of dairy digestion.

This test analyzes genetic markers in the MCM6 gene, which controls how much lactase your body produces. For most people, lactase production decreases as they get older, making it harder to digest dairy. But for those with certain variations in this gene, lactase production persists into adulthood—a condition called lactase persistence.

By pinpointing your genetic profile, this test gives you answers about why dairy affects you the way it does.
