Verify your original
Every Zudax product carries an encrypted authentication seal. Each box is sealed with a 16-character serial number that exists exactly once. Verifying it confirms the origin, the production batch, and the certification behind the bottle in your hands.
Counterfeits of luxury supplements are common and, unlike ours, unregulated. Check before you open the seal — it takes less than a minute and it is the only guarantee that matters.
Three steps, one minute
Find the seal
Locate the authentication label on the underside of your box. Beneath the silver strip you will find a 16-character serial number and a QR code.
Submit the code
Scan the QR code with your phone, or type the 16 characters into the form below. Do not share the number publicly — it can only be verified once by its owner.
Receive confirmation
We confirm the batch, the production date, and the certification for that exact bottle. If a code does not match our register, we will tell you immediately.
Verify your serial number
Enter your 16-character code below and we will check it against our production register straight away.
Only originals carry our guarantee
Zudax is sold exclusively through this website and authorised distributors. A bottle bought elsewhere, without a verifiable serial, is not covered by our guarantee and we cannot vouch for what is inside it.
