Health claims about microorganisms and use of the term "probiotic"
The use of the term "probiotic"Footnote 1 and similar representations such as "with beneficial probiotic cultures", "contains microorganisms essential to a healthy system" and "live probiotic microorganism" on food labels and/or in advertising are implied health claims. Implied health claims suggest broad, vague benefits to human health that are subject to interpretation and inference and could result in a message that is misleading and not in compliance with Subsection 5(1) of the Food and Drugs Act (FDA).
Use of the term "probiotic" and similar representations should not appear on food without being accompanied by the accepted or substantiated health claim(s) (i.e., the non-strain-specific or strain-specific health claim(s), respectively) about the live (viable) microorganism(s) contained in the food, to ensure compliance with Subsection 5(1) of the FDA.
The information in this document pertains to the use of non-strain-specific and strain -specific health claims on food, with or without the use of the term, "probiotic", along with conditions of use to help manufacturers and importers comply with Subsection 5(1) of the FDA. These conditions include:
- the eligible and acceptable microorganism(s) that should be contained in the food to carry the health claim(s);
- the minimum amount of microorganism strain(s) in colony forming units (CFU) per serving of stated size contained in the food to carry the health claim(s);
- the identity and quantity declaration requirements for the microorganism strain(s) contained in the food to carry the health claim(s); and
- any other conditions of use required to carry the health claim(s).

The widely accepted scientific definition of "probiotics" are "live microorganisms that, when administered in adequate amounts, confer a health benefit on the host" by the Food and Agricultural Organization and the World Health Organization (FAO/WHO) (2001, 2002), with minor alterations in 2013 by the International Scientific Association for Probiotics and Prebiotics (ISAPP).
- Footnote 2
-
We recommend structuring the health claim statement as follows:
[Serving size from Nutrition Facts table (or Supplemented Foods Facts table) in metric and common household measures] of (brand name) [name of food] provides [amount in CFU i.e., required minimum level of microorganism strain(s)] of (microorganism(s)) [current nomenclature of eligible microorganism(s) and strain(s)] naturally forms part of the gut flora &/ contributes to healthy gut flora.
For example:
¾ cup (175 g) of yoghurt provides 1.0 x 109 CFU of Lactobacillus acidophilus strain ABCD contributes to healthy gut flora.
- Footnote 3
-
Documentation supporting the functionality aspects of the food (i.e., identity, quantity, safety, stability, concentration and viability of the live microorganism strain(s)) should be retained and maintained.
- Footnote 4
-
The term "gut flora" may be replaced by the expression "digestive tract"
- Footnote 5
-
References reviewed for the microorganisms included: EFSA 2020, FAO/WHO 2001/2002
- Footnote 6
-
References reviewed for the nomenclature included: Oren et al., 2023, Parte et al., 2020.
- Footnote 7
-
Revisions to the taxonomy of Lactobacillus resulted in nomenclature changes to several genus names (Zheng et al., 2020) based on valid publication, legitimacy and publication priority under the rules of the International Code of Nomenclature of Prokaryotes (ICNP). The nomenclature changes affect only Lactobacillus, not Bifidobacterium.
- Footnote 8
-
The Lactobacillus name appearing in parentheses with the term, "Formerly", is optional when declaring the identity of the microorganism.
- Footnote 9
-
Evidence for the specific, individual strain of microorganism, to use the non-strain-specific health claims was voluntarily submitted for review. Health Canada concluded that the evidence for the specific individual strain of microorganism meets the evidence criteria. The specific, individual strain of microorganism has been added to the list of eligible microorganisms.
- Footnote 10
-
The microorganism strain at the minimum declared levels must survive in the food through to the end of the product's shelf-life. Survival of live microorganism strain(s) contained in food must take into consideration factors such as, but not limited to, the food matrix (the physical-chemical characteristics of the food), pH of the final product, storage environment, and packaging material.
- Footnote 11
-
We recommend using the most current nomenclature, officially recognized and accepted by international committees (e.g. International Committee on Systematics of Prokaryotes (ICSP)). Scientific nomenclature of microorganisms can change from time to time as science evolves. The most current nomenclature or "correct name" should be used to identify the microorganism, based on valid publication, legitimacy and publication priority under the rules of the International Code of Nomenclature of Prokaryotes (ICNP). To find the most current nomenclature of microorganisms, examples of online resources include NCBI (National Center for Biotechnology Information) Taxonomy at http://www.ncbi.nlm.nih.gov/taxonomy, and the List of Prokaryotic names with Standing in Nomenclature (LPSN) at http://www.bacterio.net/.
- Footnote 12
-
Identifying the strain should use the number assigned by an internationally recognized culture repository, for example, American Type Culture Collections (ATCC).
- Footnote 13
-
In mixed culture, if multiple genera are used, declaration of the quantity of each genus is generally expected. If multiple species or strains of the same genus are in food, the need for separate declaration of individual species would be determined case-by-case.
- Footnote 14
-
The Novel Foods Regulations are found in Division 28 of the Food and Drug Regulations (FDR). If you are unsure your food is novel, you can ask Health Canada for a novelty determination. For more information about novel foods, please refer to the Guidelines for the Safety Assessment of Novel Foods Derived from Plants and Microorganisms.
- Footnote 15
-
The evidence criteria for live microorganism strain(s) that are not eligible microorganisms to make the non-strain-specific health claims is based on the opinions in Hill et al., 2014
- Footnote 16
-
Premarket review and approval is not required to assess the validity of the evidence criteria. However, the evidence may be voluntarily submitted to Health Canada for review (via email to the Submission Management and Information Unit (SMIU) at smiu-ugdi@hc-sc.gc.ca) following the submission format set out in Health Canada's Guidance Documents for Preparing Health Claim Submissions. If the evidence is accepted, the microorganism strain(s) will be added to the list of eligible microorganisms.
- Footnote 17
-
No strain specific health claims have been accepted by Health Canada.
- Footnote 18
-
Premarket review and approval is not required for strain-specific health claims that do not refer to a disease listed on Schedule A.1 of the Food and Drugs Act. Manufacturers and importers should have the supporting evidence ready to disclose upon request by the Canadian Food Inspection Agency, when warranted.
