Market
Vitamin C products in Thailand include food supplements and other foods fortified with vitamin C, and the category is regulated under Thailand’s Food Act framework administered by the Thai FDA. For vitamin/mineral food supplements, Thailand specifies both a minimum nutrition-reference threshold (Thai RDI-based) and maximum permitted daily levels, including a 1,000 mg/day maximum for vitamin C. Market access is strongly compliance-driven: labels require approval and must carry specific warning statements for food supplements, and importers must obtain the appropriate Thai FDA permissions through the e-Submission system. Thai FDA consumer communications highlight risks of non-compliant vitamin C amounts and potentially misleading benefit claims, reinforcing scrutiny on labeling and advertising for this category.

Risks
Regulatory Compliance HighNon-compliance with Thai food supplement rules can block market access, including exceeding Thailand’s maximum permitted daily level for vitamin C in food supplements (1,000 mg/day) or failing label approval and mandatory warning statement requirements.Validate formula (daily intake) against MOPH Notification No.448 annex limits and prepare Thai FDA-compliant labeling (including required warnings) before submission through the Food e-Submission process.
Misleading Claims MediumThai FDA has publicly warned that some vitamin C products may not meet required conditions (e.g., vitamin C amount) but are advertised with benefit claims (e.g., immune support/antioxidant), creating enforcement and reputational risk.Align label/advertising claims to Thai health-claim conditions and ensure vitamin C levels meet any stated Thai RDI-based thresholds used for claim eligibility.
Illicit Products MediumThailand publishes actions on illegal food supplements and revoked food serial numbers, signaling ongoing enforcement risk for unlicensed, improperly labeled, or otherwise non-compliant supplement products in the market.Use only licensed import/production pathways, verify permissions/serial numbers, and maintain document control for label approvals and formula compliance.
Food Safety MediumFood supplement standards include microbiological and contaminant controls; failures against E. coli/pathogen limits or contaminant residue requirements can trigger rejection, recall, or suspension.Implement GMP-based controls and routine testing aligned to Thai FDA/MOPH requirements and maintain supplier qualification for active ingredients and excipients.
