What does the ALDH2 (Alcohol Sensitivity) gene do?

The ALDH2 (Alcohol Sensitivity) gene provides instructions for part of an enzyme called aldehyde dehydrogenase, which helps your liver process alcohol. After you drink, alcohol is first converted into acetaldehyde (a reactive, potentially harmful compound). ALDH2 helps with the next step—breaking acetaldehyde down into acetate (acetic acid), which is less toxic and easier for your body to manage.

Why is the ALDH2 (Alcohol Sensitivity) gene important?

ALDH2 is important because genetic variants can reduce how well this enzyme works—sometimes dramatically. When ALDH2 activity is lower, acetaldehyde can accumulate after alcohol intake, which may contribute to unpleasant symptoms like flushing, sweating, nausea, rapid heartbeat, and vomiting. Beyond short-term symptoms, acetaldehyde is toxic and has been linked in research to DNA damage and increased health risks in certain contexts. Your report helps you understand whether your genetics may make you more sensitive to alcohol and what that could mean for your detox health strategy.

What can I do based on my ALDH2 (Alcohol Sensitivity) results?

Based on your ALDH2 (Alcohol Sensitivity) results, you’ll receive 7 personalized recommendations focused on actionable next steps. These include dietary and supplement guidance tailored to your genotype. Depending on your results, your plan may include strategies around alcohol consumption (for example, reducing intake if your acetaldehyde clearance may be slower) and targeted nutrition support (for example, guidance related to nutrients involved in detox processes, such as vitamin B12 considerations).

Can ALDH2 (Alcohol Sensitivity) variants increase hangover or flushing risk?

Yes. Research on the ALDH2 rs671 variant shows that certain genotypes are associated with reduced ALDH2 enzyme activity, which can slow the conversion of acetaldehyde into acetate. When acetaldehyde builds up, people may experience alcohol-related flushing and other symptoms such as nausea, sweating, and a rapid heartbeat. Studies have also reported that some carriers of the rs671 “A” allele are more likely to experience hangover symptoms and may feel intoxicated more quickly. Your DNA report helps connect these well-studied genetic variants to personalized guidance you can use in daily life.

What can an ALDH2 (Alcohol Sensitivity) genetic test tell me about detox and long-term health?

An ALDH2 genetic test can indicate whether you may have reduced ability to clear acetaldehyde, a toxic intermediate produced during alcohol metabolism. This can help explain alcohol sensitivity and support more informed decisions about drinking habits and nutritional support. In the scientific literature, reduced ALDH2 activity has been associated with acetaldehyde-related toxicity and has been studied in relation to broader health outcomes, including certain cancer risks and cardiometabolic factors in specific contexts. This report turns your genetic analysis into 7 personalized recommendations—including dietary and supplement options—to help you build a more targeted detox-focused plan.

Understanding Your ALDH2 (Alcohol Sensitivity) Variants: A DNA Gene Report

Do you flush, feel nauseous, or get a racing heartbeat after just a small amount of alcohol? Ever wonder why some people can “handle” drinks while others feel awful almost immediately? Your ALDH2 (Alcohol Sensitivity) gene helps determine how efficiently your body clears a toxic alcohol byproduct—so understanding your ALDH2 genetic variants can offer meaningful insight into your detox capacity, alcohol response, and longer-term health considerations.

Key Report Highlights

This DNA report analyzes genetic variants in the ALDH2 (Alcohol Sensitivity) gene and translates your results into 7 personalized recommendations tailored to your genotype. ALDH2 is a key player in the second step of alcohol metabolism—helping convert acetaldehyde (a potentially toxic compound) into acetate, which is easier for the body to process. A compelling takeaway: when ALDH2 activity is reduced, acetaldehyde can build up after drinking and is associated with symptoms like flushing and nausea—and acetaldehyde has also been shown to damage DNA.

Personalized, Actionable Recommendations

Your recommendations are personalized based on your ALDH2 (Alcohol Sensitivity) genotype, helping you make practical, targeted choices that support detox pathways. You’ll receive a mix of dietary and supplement recommendations designed to fit your results and goals. For example, your report may suggest alcohol-intake strategies (such as limiting or avoiding alcohol if your genetics indicate reduced ALDH2 activity) and nutritional support guidance (such as discussing vitamin B12 status and food sources, since B12 may assist acetaldehyde breakdown in certain contexts).

User-Friendly Format and Trust

With actionable and easy-to-understand recommendations, the report is designed for seamless integration into your daily life. Its user-friendly format ensures accessibility, making complex genetic data understandable and practical for users at all levels of familiarity with genetic information.

The report is rooted in accuracy and reliability, backed by comprehensive scientific research from reputable sources. It has garnered the trust of over 150,000 users and 1,000+ healthcare professionals. Furthermore, the report complies with HIPAA and GDPR, ensuring your privacy and security are prioritized.

As a bartender, I used to shrug off the “Asian glow” style flushing and the next day fog. The ALDH2 (Alcohol Sensitivity) report explained the detox pathway in plain language and helped me set realistic limits instead of guessing. I tried magnesium glycinate at night and added sulforaphane a few times a week, and I notice fewer headaches after social drinks. The note about being cautious with red wine was spot on for me, it is the worst trigger. I also started thiamine on weekends out.

I always worried about why I felt sick after a drink, and this finally gave me answers. It explained my sensitivity in a way my doctor never did.

People talk a lot about alcohol tolerance on forums but nothing matched how clear this was. Instead of vague tips, it explained WHY my body reacts the way it does and what to actually do about it. Way more actionable and specific than anything I’ve come across online.
