Can Alcohol, Mouthwash or Tinctures Affect My FoodMarble Results?

Alcohol, Mouthwash & Tinctures: What You Need to Know

We know life doesn’t stop just because you’re testing with your FoodMarble device — but some things can temporarily affect your results. Here’s what to keep in mind when it comes to alcohol, mouthwash, and tinctures so you can get the most accurate readings possible.

Alcohol

If you’ve recently consumed alcohol, it’s best to refrain from breath testing.

• Alcohol can cause artificially elevated fermentation scores.
• Repeated exposure to alcohol in the breath may also damage the sensors in your device.

✨ For the most reliable results, wait until the effects of alcohol have fully passed before testing again.

Mouthwash

Many mouthwashes contain alcohol, which can temporarily skew your readings.

• Avoid using mouthwash within an hour of breath testing.
• On the day of your Challenge, it’s best to completely avoid mouthwash beforehand to ensure accuracy.

Tinctures

Some medications, such as tinctures, contain very small amounts of alcohol.

• Since tinctures are usually taken in tiny doses (a few drops), they generally don’t interfere with your results.
• If you notice higher scores after taking a tincture, simply wait an hour before your next breath test.

Final reassurance

Your FoodMarble device is built to help you uncover valuable insights about your digestion — and a few small adjustments like these can help keep your readings accurate. If you ever have concerns about how a specific medication or product might affect your results, spacing things out by an hour is usually enough to keep your data clear and reliable.

Takeaway: Avoid alcohol and mouthwash before testing, and don’t worry too much about small-dose tinctures — just give them a little space if needed.
