Beauty Queen Nguyen Thuc Thuy Tien Arrested for Promoting Fake Fibre Gummies
Former Miss Grand International faces legal action over misleading health product promotions.
Nguyen Thuc Thuy Tien, a former beauty pageant winner and popular social media influencer, has been arrested following allegations of consumer fraud linked to the promotion of counterfeit fibre gummies. Known for her significant presence on social platforms, Nguyen actively advertised Kera Supergreens Gummies, claiming they were packed with the fibre equivalent of a plate of vegetables. However, scrutiny increased after independent testing revealed the gummies contained only 16mg of fibre instead of the advertised 200mg, prompting an investigation into the influencer's claims.
Authorities discovered that the product had been manufactured using substandard ingredients and failed to meet regulatory standards, with misleading packaging that omitted key information about its fibre content and highlighted the presence of sorbitol, commonly found in laxatives. Nguyen's co-promoters, influencers Pham Quang Linh and Hang Du Muc, faced legal penalties earlier this year, both being fined and later arrested along with several company officials. On Monday, Nguyen was also taken into custody, amid reports that over 100,000 boxes of the gummies had been sold before sales were abruptly halted due to the fallout from the scandal.
Having gained fame after winning the Miss Grand International competition in 2021, Nguyen had become a sought-after figure among Vietnamese brands and television productions, receiving accolades from various sectors including governmental commendations. The recent developments pose significant reputational damage not only to Nguyen, but also to influencers and marketing practices related to health products in Vietnam.
