What Is Alcohol Intolerance?
Alcohol intolerance is when your body struggles to break down alcohol properly. Normally, your liver processes alcohol in two main steps. First, enzymes called alcohol dehydrogenase (ADH) turn alcohol into a toxic chemical called acetaldehyde. Then, another set of enzymes called aldehyde dehydrogenase (ALDH) quickly changes acetaldehyde into a harmless substance called acetate.
Some people have genetic variations that disrupt this process, leading to a buildup of acetaldehyde even after moderate alcohol consumption. This can lead to immediate reactions like facial flushing and nausea, as well as increased risks of esophageal cancer and other health problems. Alcohol intolerance often runs in families and is more common in certain ethnic groups.

The Genetics of Alcohol Metabolism
The way your body handles alcohol depends on specific genes that control the enzymes involved in breaking down alcohol.
- ADH1B and ADH1C: These genes help produce enzymes that convert alcohol into acetaldehyde. Changes in these genes can make this happen too fast, leading to quick discomfort after drinking even small amounts of alcohol.
- ALDH2: This gene affects how fast acetaldehyde is changed into acetate. Variations in this gene can slow down this conversion, letting acetaldehyde hang around in your body longer and causing stronger symptoms of intolerance.
Understanding your specific genetic variations in these genes helps explain your individual responses to alcohol and can inform future choices about drinking.

Understanding Your Results
The DNA Alcohol Test analyzes three key variants linked to alcohol metabolism:
Gene | Variants | Description |
---|---|---|
ADH1B | rs1229984 | This variant can make your body break down alcohol into acetaldehyde faster, leading to quicker and more intense symptoms like facial flushing and discomfort. |
ADH1C | rs1693482 | This variant can slightly increase how much acetaldehyde your body makes from alcohol, contributing to intolerance symptoms. |
ALDH2 | rs671 | This important variant can greatly slow down how quickly your body clears acetaldehyde, causing strong reactions like flushing and an increased risk of esophageal cancer. |
By analyzing these variants, this test helps you understand your body’s specific reactions to alcohol, enabling you to make more informed choices about drinking.
