Feed for particular nutritional uses (PARNUTs) authorisation guidance

PARNUTs are feedstuffs for particular nutritional purposes, also known as dietetic feed, for animals’ health. PARNUTs meet the specific nutritional needs of animals whose bodily functions are, or could be, temporarily or irreversibly impaired. 

PARNUTs can satisfy a specific nutritional purpose by: 

• particular composition 
• particular method of production 

Feed intended for particular nutritional purposes may only be marketed in Great Britain (GB) if: 

• its intended use is included in the list of intended uses, and 
• it meets the essential nutritional characteristics for the respective particular nutritional purpose included in that list 

Assimilated Regulation (EU) 2020/354  has established a list of intended uses of feed intended for particular nutritional purposes. 

The process to update the list of intended uses can be initiated by submitting a request. 

New requests

Use our regulated products application portal  to make a request to update the list in GB by:  

• adding an intended use of a PARNUT, or  
• adding or changing the conditions associated with an existing particular intended use of a PARNUT  

This is where you will be asked to upload all the documents to support your application, which will form your dossier. There is no fee for the application.  

There is no specific guidance available for applying to change PARNUTs categories. However, your application should clearly set out the request and include a supporting dossier demonstrating that the specific composition of the feed:  

• fulfils the particular intended nutritional purpose  
• has no adverse effects on animal health, human health, the environment or animal welfare  

Ongoing applications

If you submitted a request for a new PARNUT category or a change to an existing category to the EU before 1 January 2021 and the consideration of this application has not been completed, you will need to submit your application to the FSA, using our regulated products application portal.
