Ergothioneine USP, a naturally occurring amino acid derivative, has gained significant attention in recent years due to its potent antioxidant and cytoprotective properties. As a leading supplier of Ergothioneine USP, I am often asked about the regulations governing its use in different countries. In this blog post, I will provide an overview of the regulatory landscape for Ergothioneine USP across various regions, highlighting the key differences and similarities.

North America

United States

In the United States, Ergothioneine USP is generally recognized as safe (GRAS) when used in accordance with good manufacturing practices (GMP). The Food and Drug Administration (FDA) does not have specific regulations for Ergothioneine USP, but it falls under the broader category of dietary supplements. Dietary supplements are regulated under the Dietary Supplement Health and Education Act (DSHEA) of 1994, which requires manufacturers to ensure the safety and labeling accuracy of their products.

Manufacturers of Ergothioneine USP supplements are responsible for conducting their own safety assessments and providing evidence of the product's safety and efficacy. They must also comply with the FDA's labeling requirements, which include listing the product's ingredients, serving size, and any health claims. Health claims must be supported by scientific evidence and must not be misleading.

L-Arginine α-Ketoglutarate

Canada

In Canada, Ergothioneine USP is regulated as a natural health product (NHP) under the Natural Health Products Regulations (NHPR). NHPs are defined as substances that are used for the purpose of maintaining or promoting health, preventing or treating a disease, or modifying a physiological function.

To sell Ergothioneine USP as an NHP in Canada, manufacturers must obtain a product license from Health Canada. The license application process involves providing evidence of the product's safety, efficacy, and quality. Manufacturers must also comply with the NHPR's labeling requirements, which include listing the product's ingredients, dosage, and any health claims. Health claims must be supported by scientific evidence and must not be misleading.

Europe

European Union

In the European Union (EU), Ergothioneine USP is regulated as a novel food under the Novel Food Regulation (EU) 2015/2283. Novel foods are defined as foods that were not used for human consumption to a significant degree within the EU before May 15, 1997.

To place Ergothioneine USP on the market as a novel food in the EU, manufacturers must submit a novel food application to the European Commission. The application must include detailed information on the product's composition, manufacturing process, safety, and nutritional value. The European Commission will then assess the application and may authorize the product for use in the EU if it is considered safe for human consumption.

Once authorized, Ergothioneine USP can be used in food products in the EU, subject to certain conditions and restrictions. Manufacturers must comply with the EU's food labeling requirements, which include listing the product's ingredients, nutritional information, and any health claims. Health claims must be supported by scientific evidence and must not be misleading.

United Kingdom

Following Brexit, the United Kingdom (UK) has established its own regulatory framework for novel foods. Ergothioneine USP is regulated as a novel food in the UK under the Novel Foods Regulations 2021. The regulatory process for novel foods in the UK is similar to that in the EU, with manufacturers required to submit a novel food application to the UK's Food Standards Agency (FSA).

The FSA will assess the application and may authorize the product for use in the UK if it is considered safe for human consumption. Once authorized, Ergothioneine USP can be used in food products in the UK, subject to certain conditions and restrictions. Manufacturers must comply with the UK's food labeling requirements, which include listing the product's ingredients, nutritional information, and any health claims. Health claims must be supported by scientific evidence and must not be misleading.

Asia

Japan

In Japan, Ergothioneine USP is regulated as a food additive under the Food Sanitation Act. Food additives are substances that are added to food for the purpose of improving its quality, preservation, or processing.

To use Ergothioneine USP as a food additive in Japan, manufacturers must obtain approval from the Ministry of Health, Labour and Welfare (MHLW). The approval process involves submitting a detailed application that includes information on the product's composition, manufacturing process, safety, and intended use. The MHLW will assess the application and may approve the product for use in Japan if it is considered safe for human consumption.

Once approved, Ergothioneine USP can be used in food products in Japan, subject to certain conditions and restrictions. Manufacturers must comply with the MHLW's food labeling requirements, which include listing the product's ingredients, usage limits, and any other relevant information.

China

In China, Ergothioneine USP is regulated as a new food raw material under the Administrative Measures for the Safety Review of New Food Raw Materials. New food raw materials are substances that have not been used in food in China before and require safety evaluation before they can be used in food products.

To use Ergothioneine USP as a new food raw material in China, manufacturers must submit a safety evaluation application to the National Health Commission (NHC). The application must include detailed information on the product's composition, manufacturing process, safety, and nutritional value. The NHC will assess the application and may approve the product for use in China if it is considered safe for human consumption.

Once approved, Ergothioneine USP can be used in food products in China, subject to certain conditions and restrictions. Manufacturers must comply with the NHC's food labeling requirements, which include listing the product's ingredients, usage limits, and any other relevant information.

Other Regions

Regulations for Ergothioneine USP in other regions may vary. In some countries, it may be regulated as a dietary supplement, food additive, or novel food, while in others, it may not be specifically regulated at all. It is important for manufacturers and suppliers to familiarize themselves with the regulations in each country where they intend to sell their products to ensure compliance.
