Call for data for the Scientific Opinion on the evaluation of the safety in use of plant preparations containing berberine

Deadline for registering interest: 07/08/2023

Deadline for submission of data: 12/01/2024

Background

In the context of Article 8(2) of Regulation (EC) 1925/2006 on the addition of vitamins and minerals and of other substances to foods, the European Commission requested EFSA to assess the available information on the safety of berberine in plant preparations used in food supplements.

In order to ensure a comprehensive assessment, EFSA launches a public call for all potentially relevant available data (published, unpublished or newly generated data) from interested parties. EFSA will then consider the relevance of the information provided for the risk assessment of berberine. The submission of the requested information is without prejudice to the final opinion of the NDA Panel.

Overall objective

The purpose of this call for data is to offer interested parties (e.g. governments, food business operators, national food authorities, research institutions, academia) and/or other stakeholders the opportunity to submit documented information (published and/or unpublished) relevant to the safety evaluation of berberine in plant preparations used in food supplements.

In case a causal relationship will be identified between the dietary exposure to berberine and an adverse effect, EFSA will investigate whether protoberberine alkaloids which share the same molecular structure as berberine exert a similar effect through a similar mode of action. In such case, the combined exposure from berberine and the implicated protoberberine alkaloids will be assessed. Thus, EFSA is looking for data also on protoberberine alkaloids other than berberine, as listed in Table 1.

Specific objectives

  • Specific Objective 1: occurrence data

EFSA is looking for analytical data on the content of berberine and other protoberberine alkaloids listed in Table 1 n preparations of plants used in food supplements. The list of plants included in this assessment can be found in Appendix A.

  • Specific Objective 2: use levels for supplements

EFSA is looking for use levels recommended by manufacturers for food supplements containing berberine and other protoberberine alkaloids listed in Table 1.

  • Specific Objective 3: biological and toxicological data

EFSA is looking for biological and toxicological data to support the assessment of a causal relationship between dietary exposure to berberine as single substance and/or in plant preparations and the identified potential adverse effects, including data on absorption, digestion, absorption and metabolism (ADME) for berberine and within the food matrix.

EFSA is interested in collecting data also on protoberberine alkaloids other than berberine, as listed in Table 1.

Data sought and data submission format

EFSA kindly invites interested parties to submit information as outlined below for each specific objective.

Specific objectives 1 and 2 (occurrence data and use levels for supplements)

To submit data in the context of specific Objectives 1 and 2, please fill in the Excel file downloadable on the EFSA webpage of this call. This Excel file contains a selection of different data fields to collect information considered as essential to assess the reliability of the data before being used for the exposure assessment. Dedicated data fields are also included for food supplements (dose forms, weight of the dose form, etc.) and tea/herbal infusions (e.g. preparation) to allow precise and accurate estimations of the dietary exposure.

Data providers are encouraged to provide the information on the use levels in the appropriate data field described in the above-mentioned Excel file. Should you require assistance when filling in the Excel file for analytical data/use levels or have specific questions on how to send the data, please contact nda_callfordata [at] efsa.europa.eu (nda_callfordata[at]efsa[dot]europa[dot]eu).

OTHER OPTION TO SUBMIT OCCURRENCE DATA

Please be informed that together with sending analytical data/use levels in the context of this call for data, it is also possible to submit analytical data as part of the ‘EFSA Call for continuous collection of chemical contaminants occurrence data in food and feed’. These data must be submitted in electronic format (XML) to the EFSA Data Collection Framework (DCF) in SSD2 (Standard Sample Description version 2) format. You find all the details about this call here (deadline 31 August 2023).

 

Specific objective 3 (biological and toxicological data) 

EFSA is seeking data to answer the the following questions:

1. What is the absorption, distribution, metabolism and excretion (ADME) of berberine?

2. What are the potential mode(s) of action for the relationships found between berberine as a single substance and adverse health effects?

3. What is the dose-response relationship between dietary exposure to berberine as single substance and risk of identified potential adverse effects in humans or animals?

Examples of correct data formats:

  • full study reports
  • articles or reports under preparation (newly generated data)

Examples of incorrect data formats:

  • abstracts
  • posters
