Thai supplement labeling and health claims are regulated, not discretionary. In Thailand a supplement's health claim is not a marketing choice. It is a regulated declaration drawn from a positive list, and a claim that is not on the list cannot be used without case-by-case assessment. A disease claim cannot be used at all. Brands that design their packaging before they confirm what they can say rebuild it later, in Thai.
Thai FDA requires the consumer label to be in Thai. Foreign-language text may be added, but the Thai label carries the mandatory information, and it cannot be finalized until the product clears approval. The required elements are set in MOPH No. 293 B.E. 2548 (2005).
The category term ผลิตภัณฑ์เสริมอาหาร must appear as part of the name.
Assigned on approval and shown on the label.
Name and address, and for imports the importer's details plus the country of the producer.
Net quantity, the name and amount of the main ingredients, and an expiration date.
A mandatory warning accompanies the product.
A health claim on a Thai supplement label must come from the permitted set, under Thai FDA Notification No. 447, effective 2 July 2024. Claims on the list can be used without pre-approval. A claim that is not on the list cannot simply be written onto the label. It must be submitted for case-by-case assessment to a Thai FDA-registered certifying body.
The largest category, covering 28 items across 135 permitted statements. These describe the role of a nutrient in normal body function.
8 permitted statements across six ingredients, for functions beyond basic nutrition.
The narrowest category, 4 permitted statements across two ingredients, relating a component to reduced risk of a condition.
Requires a health-claim assessment submitted to a Thai FDA-registered certifying body, evaluated case by case. This is a substantive evidence process, not a formality.
A food supplement cannot claim to prevent, treat, or cure disease. A claim of that kind does not just risk rejection of the label. It reclassifies the product as a drug, moving it out of the food regime and into a registration pathway it was never built for. The line between a permitted function claim and a prohibited disease claim is where many foreign brands misjudge the Thai market, because wording that is routine in a home market can read as a disease claim under Thai rules.
Before a client commits to packaging, we map the claims they want to make against what Thai FDA permits, and we tell them which claims are available on the list, which require assessment, and which cannot be made at all.
We treat the claim review as a commercial decision, not only a compliance one. A brand built on a claim that Thailand will not allow needs to know that before artwork, inventory, and a launch plan are committed to it.
We prepare the Thai-language label to meet the mandatory requirements, and where a desired claim is worth pursuing through assessment, we manage that submission rather than quietly dropping the claim.
