Ngan Collagen sued TikToker for defaming the company, affirming that the product was legal?

After more than 3 months of coordinating with the authorities to verify, Ngan Collagen officially announced that the company had been vindicated, affirming that all products are legal, clear in origin, safe and guaranteed.

After more than 3 months of working with the authorities, Ngan Collagen (real name Tran Thi Bich Ngan, born in 1995) officially announced that her company – N-Collagen Import and Export Co., Ltd. – had been vindicated in the case related to TikToker Duong Ngoc Hiep.

Specifically, on November 6, the female TikToker shared the results of the settlement of the complaint sent by her company to the authorities. This application states that Mr. Duong Ngoc Hiep has repeatedly posted videos containing false information on TikTok, defaming the honor and reputation of the N-Collagen business, and slandering the product.

After the verification process, the Police of Xuan Truong Ward (Da Lat City, Lam Dong) confirmed that the content of the denunciation was true. According to the results, Mr. Hiep had the act of spreading false and fabricated news, seriously affecting the company's image. The announcement dated October 31, 2025 said that the case is being considered and handled by the authorities in accordance with the law.

Responding on her personal page, Ngan Collagen shared: "The test results confirm that all N-Collagen products have legal documents, clear origin, tested and guaranteed safety. Before the act of defamation, the authorities administratively sanctioned an individual named Hiep 7.5 million VND for slander."

In the evening of the same day, Ngan Collagen also posted a series of photos taken with her parents in front of the villa worth 500 billion VND. The post quickly attracted the attention of the online community.

When asked about the fine of 7.5 million VND, she said: "Because my side does not claim compensation, the fine only stops at administrative. But if this person continues to slander me, my side will sue a second time and claim compensation for damages."

Previously, Mr. Duong Ngoc Hiep shared many videos condemning Ngan Collagen, saying that the information she posted was "exaggerated" or "dishonest". In a livestream, Mr. Hiep also brought N-Collagen products to "verify", but there was no independent third party to certify this result. Currently, Mr. Hiep's TikTok account with more than 42,000 followers is receiving many mixed comments after the case was announced.

On November 5, the Department of Food Safety of Ho Chi Minh City. Ho Chi Minh City also said that it is coordinating to inspect the operation, business and advertising of food products, including products promoted by Ngan Collagen. The representative of the Department recommends that consumers should temporarily refrain from buying or using products advertised by Ngan Collagen, including N-Collagen Lemon Plus, N-Collagen Cordyceps Bird's Nest Plus and Apple Candy to eliminate belly fat, until the official test results are available.

However, on her personal page, Ngan Collagen still regularly posts videos introducing the product. Since the beginning of October, she has been actively promoting Cordyceps N-Collagen, saying that the product has reopened for sale after 6 months of "selling out".

The incident between Ngan Collagen and TikToker Duong Ngoc Hiep shows the serious consequences of spreading false information on social networks. At the same time, the verification results from the authorities are also clear proof that this business has been vindicated, protecting its honor and image in the public. Strengthen the trust of long-term buyers and partners.
