Is my supplement tub real? A 5 step checker for Thailand

By the UnReal Supplements team. Sources and catalog last checked: 2026-11-03.

Short answer

Check a supplement in five steps: find the 13 digit registration number on the label, look it up on the official Thai FDA channels, match the product name to the record, use the brand's own check if it has one, and check the barcode. This tool checks the number pattern and our own catalogue only. It certifies nothing.

Five steps, in order. Steps 1, 2 and 5 take a minute with the tub in your hand.

1. Find the registration number on the label

Thai food supplement labels print a 13 digit registration number, in the pattern 12-3-45678-9-0123. Type it below to check the pattern only.

Registration number from the label

2. Check the number on the official Thai FDA channels

Search the number yourself. These are the channels the Thai FDA publishes, read on 2026-11-03.

The Thai FDA home page prints: "สายด่วน อย. 1556" and "ร้องเรียนด้านผลิตภัณฑ์สุขภาพ : 1556@fda.moph.go.th" (read 3 พ.ย. 2569).

3. Match the product name to the record

A real number on the wrong product is still a problem. Tick each one that is true.

The product name on the official record matches the name on my tub
The brand or maker on the record matches the label
The pack type matches (powder, capsule, bar)

If any does not match, do not rely on the number. Ask the seller, or call the FDA line above.

4. Use the brand's own check, if it has one

Some brands print their own verification code. Optimum Nutrition describes its TRU Seal below, on its India support page. Its own list of verification pages covers the UK and Europe, the US, India and Latin America, and none for Thailand (read 2026-11-03).

For other brands, use the brand's own website or customer service, and check the seal, batch code and expiry as in our guide.

5. Check the barcode against our catalogue

Type the barcode number under the bars. We tell you if it is a product we list.

Barcode number

A catalogue match shows the number belongs to a product we sell. A copied barcode can be printed on anything, so this is one check among five, not proof.

What this tool does and does not do

The checker walks you through the label and points to official channels. It can check two things on this page: the pattern of a 13 digit registration number, and whether a barcode belongs to a product we sell. Whether a number is really registered has to be checked on the Thai FDA's own channels.

We name no seller, shop or brand as fake, and keep no warning list of our own. When we cite an authority we quote its wording with the date we read it.

Why the name must match the number

A real registration number can be printed on a different product. Finding the number in the system is not enough: match the product name, maker and product type in the official record to the label on your tub. If anything differs, ask the seller or call the Thai FDA line, 1556.

The health risks of adulterated supplements and mislabelled protein are covered, with sources, in our guide to fake supplements in Bangkok.

Buy where you can check first

The simplest protection is buying from a seller that lets you inspect the product before you pay. At UnReal Supplements inside UnReal Gym on Sukhumvit Soi 24 you can hold the tub and read the seal, expiry and batch code first.
