Thailand Health Claims for Food Supplements and Tips for the Industry

Subscribe to Updates

Thailand is a member state of the ASEAN Economic Community, and next year, it is expected that the ASEAN Harmonization of Traditional Medicines and Health Supplements will be signed by the economic minister of each ASEAN country. Following ratification, the ASEAN Guidelines on Claims and Claims Substantiation for Traditional Medicines and Health Supplements will become the standard guidelines in the region, and various implementation efforts and instruments will follow. These guidelines cover a wide range of medicines and supplements; however, it is not possible to cover all herbal products.

There are three types of health supplement claims: nutritional claims, functional claims, and disease risk reduction claims. Examples of the three types of claims include the following:

  • Nutritional claims: supplements nutrition, nourishes the body, supports healthy growth and development, etc.
  • Functional claims: maintains healthy joints, supports immunity, maintains liver function, etc.
  • Disease risk reduction claims: helps to reduce risk of dyslipidemia, helps to reduce risk of osteoporosis, etc.

The degree of evidence required for substantiating disease risk reduction claims is higher than for functional claims and nutritional claims. Functional claims and disease risk reduction claims must be substantiated by efficacy studies and the relevant toxicity data. It is the responsibility of the health supplement company to provide the required evidence in order to comply with the criteria for making such claims.

Tips on Health Claims for Health Supplements

1. Nutritional Claims

For essential nutrients such as vitamins and minerals, as listed by the Thai Food and Drug Administration (FDA), the amount included in a supplement must be between 15% and 100% of the Thai Recommended Daily Intake (RDI) values. Rules for specific kinds of nutritional claims are provided in the Notification of the Thai FDA RE: Nutrient Function Claims. For example, the nutrients that can be claimed as boosting the immune system include vitamin A, B6, B12, folic acid or folate, vitamin C, vitamin D, iron, zinc, copper, and selenium.

2. Functional and Disease Risk Reduction Claims

Phytochemicals, fish oil or animal extracts, and probiotics are substances not listed as nutrients by the Thai FDA. These substances are frequently used in health supplements, with claims as to their function and disease risk reduction properties. Some of these substances have specific laws and regulations regarding conditions of use and product claims.

For example, the Notification of the Ministry of Public Health RE: Use of Probiotics in Food prescribes the requirements of well-designed human intervention studies. Although the notification does not mention the number of studies required for submission to the Thai FDA, at least two reports of human interventional studies from two independent study centers are required by the Thai FDA.

For other products or food substances to be used in food products, the Thai FDA published the Manual for the Public RE: Applications for Health Claim Assessment. The manual follows the requirements in the ASEAN Guidelines. To substantiate claims, companies must submit:

  1. Well-designed human interventional studies;
  2. Meta-analysis/systematic review of said the substance or food product; or
  3. Scientific opinions from benchmark authorities, such as the EFSA Scientific Committee.

The selection of food substances and the design of a product formula are bases for claiming that a product is a health supplement. Science alone is not always enough—legal compliance and regulatory strategies are required for the acceptance of health claims by the authorities, which is paramount to determining the health supplement producer’s success.

Patent is an essential piece of the amended Law on Intellectual Property (“Amended IP Law”), which was passed by the National Assembly of Vietnam on June 16, 2022, and will take effect on January 1, 2023 (except for the regulation on protection of experimental data for agrochemical products, which will take delayed effect on January 14, 2024). Among the amended and supplemented contents of the Amended IP Law, there are notable patent-related amendments to Article 60 on assessing the novelty of inventions and Article 96 on grounds for invalidating patent protection titles. We discuss these changes below. Secret Prior Art Under Article 60.1 A significant amendment to Clause 1, Article 60 of the Amended IP Law on the novelty of inventions is to broaden the scope under which an invention can be considered to have lost its novelty. For the first time in Vietnam, “secret prior art” –a patent application with an earlier filing date or priority date but published on or after the filing date or priority date of an examined patent application – is introduced as a prior art document. In the diagram above, at the time of filing of the A2 application, secret prior art A1 has been filed but not yet published, making it inaccessible to the public. At this point, only the A1 applicant and the IP Office are aware of the A1 application. Under the current provisions of the 2005 IP Law, as amended in 2009 and 2019, the A1 patent application is not eligible to be a prior art document when assessing the novelty of A2. However, based on the “first-to-file principle” and the principle of priority, the IP Office has still had other approaches to bar the patentability of an A2 patent application if there is such an A1 application.

Thailand’s cannabis cultivation licensing scheme for the country’s transition toward legalization of the plant has now come to an end. The Ministry of Public Health (MOPH) announced in the Government Gazette that from June 9, 2022, “only cannabis extract with tetrahydrocannabinol (THC) of more than 0.2% by weight will be considered a narcotic.” This means that now anyone can grow, sell, or purchase cannabis seeds, plants, and inflorescence freely in Thailand, and licenses for the cultivation, possession, and distribution of cannabis are no longer required. Neither the number of cannabis plants nor the place of cultivation is restricted. It is thus the beginning of a new chapter for cannabis cultivation in Thailand, with many opining that now is a good time to enter this exciting and growing industry. The journey to this point began in 2019, when Thailand amended its laws on cannabis to allow for treatment for medical purposes, with one of the prerequisite conditions being that the cannabis must be grown in Thailand. The law was further amended to promote commercialization of the cannabis industry, allowing for cannabis to be added to food and beverages, cosmetics, and herbal products. In addition, three traditional cannabis-based formulas were listed in the universal healthcare coverage scheme, which means that almost all Thais have access to traditional cannabis recipes without cost. The successful launch of medical cannabis and its applications, and its viability as an economic industry, have become a national agenda and priority policy of the MOPH. In order to achieve the above outcomes, several legal frameworks and guidelines throughout the product’s lifecycle have been developed. For example, the Thai Food and Drug Administration (FDA) has so far granted licenses to cultivate cannabis (also known as a license to manufacture a narcotic) on more than 1,977 acres (around 800 hectares).

New technologies and production processes in the food industry have led to novel foods becoming increasingly important to both food manufacturers and the consuming public worldwide. This is very much the case across a number of jurisdictions in Southeast Asia. “Novel foods” refer to new food production processes, foods, and ingredients that have not yet been commonly used for human consumption, so these innovative foods require safety assessments before companies can produce and market them. While rules for these safety assessments are already part of novel food regulations in several other jurisdictions—such as the novel food regulations in the United Kingdom and European Union adopted in 2003, and the major reform of food safety laws in the United States passed in 2011 under the Food Modernization Act—similar rules governing the assessment of novel foods are relatively new or yet to be introduced in many parts of Asia. Nevertheless, it is important to understand the laws and practices that apply to safety assessments and the process of bringing novel foods to market in jurisdictions in the region. This article provides some clarity in this regard by summarizing important practical information on novel foods and the relevant required safety assessments in Indonesia, Thailand, and Vietnam.   Indonesia Regulator National Agency for Drug and Food Control (NADFC); frequently referred to as BPOM (Badan Pengawas Obat dan Makanan).

Since the onset of the COVID-19 pandemic and the ensuing safety measures, many Thai retailers have shifted their sales toward online platforms. Unsurprisingly, counterfeiters have followed suit. The online sale of counterfeit healthcare and other life sciences products (e.g., food, cosmetics, and medical devices) is an area of significant concern, as it is particularly prevalent, damaging, and complex in relation to Thailand’s laws. This article outlines this type of counterfeiting activity in Thailand and explains some important tools brand owners have for fighting it. Counterfeiting Operations Although illicit operations seek to avoid being identified by authorities and brand owners, investigations by law enforcement and Tilleke & Gibbins on behalf of clients have yielded some insights into how these illegitimate sellers typically operate. Often, consumers are first exposed to these counterfeit life sciences products by paid social media advertisements that link to social media accounts set up by sellers impersonating brand owners. This brand impersonation may include unauthorized use of a trademark or trade name as part of the account name, and unauthorized reproduction of official advertisement artwork or product descriptions, taken directly from the official social media account. From the fake social media account, consumers are usually directed to a merchant website that contains consumer reviews, which are entirely fabricated. While not every counterfeiting operation follows this exact blueprint, employing some variation of these methods lends counterfeiting platforms the ability to proliferate through multiple iterations, as well as believability in the eyes of consumers. How Brand Owners Can Take Action Life sciences brand owners often discover that their products have been targeted by counterfeiters when a counterfeit item injures or negatively impacts a consumer. Thinking that the product is genuine, the consumer may then complain to the brand owner, or worse, file a complaint with the authorities. Many times
