NA NOI, THAILAND, 30 SEPTEMBER 2026 —
Na Noi, Thailand – A health‑training course in the northern Thai province saw 104 of the 163 participants rushed to hospital after taking a dietary supplement that triggered chest tightness, facial and body flushing, skin rashes and elevated blood pressure, local media reported on Sunday.
Market Impact
The incident unfolded when an invited speaker introduced the supplement and encouraged attendees to try it. Within about 15 minutes of ingestion, several volunteers began to experience the symptoms, and some collapsed before being taken to Na Noi Hospital for emergency care. Of the 129 participants who consumed the product, 104 reported adverse effects while the remaining 25 were unaffected.
Twenty‑one of those affected received treatment at the hospital, seven of whom were admitted to wards for further observation, said Chatchapat Phanit, an assistant medical officer with the Nan Provincial Public Health Office.
Health officials are now monitoring all affected participants, particularly those who require close observation, according to Phanit. The hospital and the provincial public‑health office have collected samples of the supplement for laboratory analysis at the Regional Medical Science Center. “An investigation is underway to identify whether any contaminant or specific ingredient in the product is linked to the reported symptoms,” Phanit said on Monday.
Police from Na Noi Police Station have already met the product’s distributor to obtain information and hear explanations about the episode. The distributor claimed that facial and body flushing and vasodilation are normal reactions to the supplement. Authorities noted that the distributor’s explanation still needs medical assessment and formal laboratory verification.
The exact cause of the incident remains unconfirmed, and officials are awaiting the lab results to determine whether the supplement is directly responsible for the symptoms.
The episode highlights the risks associated with unregulated health products, a concern for Malaysian consumers who often purchase supplements across borders or online. Malaysia’s Ministry of Health has repeatedly warned that products lacking clear safety information can pose serious health hazards, and the Na Noi case underscores the need for vigilance when evaluating such items.
The next steps involve completing the laboratory analysis of the supplement, after which health and law‑enforcement agencies will decide whether further action, such as product recalls or legal proceedings, is warranted. Phanit urged the public to exercise caution with products whose safety data are unclear, reinforcing ongoing regional efforts to safeguard consumer health.
