Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, pursuant to the answer of 1 December 2025, to question 93987 on Phenylketonuria: Health Foods, (a) If he will confirm the latest number of individuals with Phenylketonuria receiving low-protein foods on prescription and (b) if his Department will make an assessment of the potential positive business implications on manufacturers and suppliers of low-protein foods in the event of a shift from prescriptions to financial support.

Regarding the number of individuals with Phenylketonuria receiving low-protein foods on prescription, the NHS Business Services Authority (NHSBSA) does not hold this information centrally.

NHBSA prescription data does not contain information about the indication, medical condition, or reason that a prescription was issued.

We are not considering shifting to a different model to support those with Phenylketonuria thus do not intend to assess the potential impact on manufacturers and suppliers.
