China Officially Released the Function Evaluation Methods for Health Food: Summary of Key Changes

The Technical Specifications for Testing and Evaluation of Health Food (2003 Version) was abolished in July 2018. After five years, on August 31, 2023, China’s State Administration for Market Regulation (SAMR) finally released the Directory of Health Functions Available to be Claimed by Health Food – Non-nutrition Supplements (2023 Version) and the supporting documents, including the long-awaited health food function evaluation methods.

These documents include:

  • Directory of Health Functions Available to be Claimed by Health Food – Non-nutrition Supplements (2023 Version);
  • Guidelines on Testing and Evaluation of Health Food Functions (2023 Version);
  • Testing and Evaluation Methods for Health Food Functions (2023 Version);
  • Guidelines on Ethical Review of Health Food Human Feeding Trials (2023 Version); and
  • Interpretation to Directory of Health Functions Available to Be Claimed by Health Food – Non-nutrition Supplements (2023 Version) and the supporting documents.

Since August 31, 2023, registration of new health food products has officially started. CIRS will guide you through the key changes in the above-mentioned documents and summarize the testing requirements for registered health food products.

PART 1: Key changes in the five new documents

1. The total number of health functions has been reduced from 27 to 24, with revisions made to the wording used to describe the health claims.

Aligning with the earlier draft for public comment, the health claims allowed for functional health food have been reduced from the original 27 to 24. Three outdated functions, namely boosting lactation, promoting growth and development, and improving skin oiliness were formally removed. Moreover, revisions have been made to the wording for the remaining 24 health functions, making the terminology more standardized and precise. (See Table 1 for more details).

2. Although the overall requirements for function evaluation remain unchanged, there are still updates to the details.

Through comparison, we discovered that the requirements for conducting animal testing and (or) human feeding trials for the 24 health functions remain unchanged. For instance, the claim “aids in boosting immunity” still requires animal testing only; “contributes to anti-oxidation” still requires both animal testing and human feeding trials. However, there are still some differences, such as more testing programs and changes in the evaluation criteria.

It’s important to note that the new function evaluation methods have been shifted from mandatory to recommended.

3. The transition requirements for products approved previously are clarified.

– Products with health functions listed in the Directory: A five-year transition period is set to standardize the health claims. If the products are evaluated based on the methods recorded in the 1996 version, then related enterprises should redo or supplement functional tests (See Table 2 for details).

– Products with health functions not listed in the Directory: Apply for change of health functions or make declarations on the listing of their health functions within five years.

– Registration certificates with no valid period and no product technical requirements: Apply for change of certificates in accordance with current regulations in light of the situation.

Note:Testing and Evaluation Methods of Health Food Functions (2023 Version)[1] is a revision based on Technical Specifications for Health Food Testing and Evaluation (2003 Version)[2] and the Announcement of 9 Health Function Evaluation Methods including Anti-oxidation[3] issued by the former State Food and Drug Administration (SFDA) in 2012. No further re-evaluation materials for health functions is required if the evaluation requirements and standards of the original function test report are based on the above-mentioned two documents.In accordance with previous requirements for the re-registration of product health function evaluations, if the evaluation requirements and standards of the original function test report are lower than the current ones, corresponding health function re-evaluation materials must be provided when adjusting health function claims. It can be provided in two ways:A post-market population consumption function evaluation research report issued by a third-party testing organization. Data collection, management, and analysis should be standardized, truthful, and traceable, providing effective technical support for the product’s health functions.For those unable to provide such report, a function test report redone in accordance with the three documents ([1, 2, 3]) mentioned earlier can be provided. For those with original function test report evaluation requirements and standards aligned with the Health Food Function Evaluation Procedures and Methods (1996 Version), the requirements are outlined in Table 2. “–” indicates that no further health function re-evaluation materials required.

PART 2: What tests are required for health food registration?

In July 2018, the Technical Specifications for Health Food Testing and Evaluation (2003 Version) was abolished, leaving no testing basis, thus hindering the registration progress. To address this issue, SAMR initiated a comprehensive revision to the regulations. So far, documents on toxicological assessment methods, sanitary physicochemical inspection standards, microbial safety assessments, and function evaluation methods, have been formally released. This has allowed health food registration and testing to officially resume.

Currently, when applying for health food registration, the following test reports need to be submitted:

S.N.Testing itemsBasic requirements
13-batch self-testsAll technical indicators of the product’s technical requirements should be included.
23-batch tests of functional components or characteristic ingredients, hygiene, and stabilityOrdinary samples typically undergo accelerated testing, with a general shelf life of two years. These samples should be stored for three months under conditions of 37±2℃, RH75±5%, and protected from direct sunlight. Sampling and testing should be conducted at zero, one, two, and three months. It is noteworthy that data from the zero-month assessment can be based on the results of hygiene testing performed on samples from the same batch.
3Methodological validation on functional components or characteristic ingredients test methodsI. When referring to national standard methods, it is also necessary to assess the detection limit, precision, accuracy, and linear range of the method;II. Currently, the methodological research data for probiotic-like signature component testing is not considered a mandatory requirement.
4Toxicology testsI. These typically include: acute oral toxicity tests, three genetic toxicity tests, and 28-day oral toxicity tests;II. The testing should be conducted in the same laboratory as the functional tests, using the same batch of samples, and one of the batches used for stability testing.
5Animal function tests and (or) human feeding trialsThe toxicological testing should be carried out in the same laboratory as the functional tests, using the same batch of samples, and one of the batches used for stability testing.
6Other tests, if necessary (depending on the specific product, such as strain identification, and strain virulence test)./
