Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, whether his Department has made an assessment of the efficacy of Vitamin C in boosting immunity to covid-19.

In 2020, the Scientific Advisory Committee on Nutrition (SACN) conducted a rapid scoping exercise on nutrition and immune function in relation to COVID-19, which included consideration of vitamin C and found a lack of robust evidence to suggest that specific nutrients or supplements can prevent individuals from catching COVID-19 or mitigate its effects.

Public Health England and the SACN are continuing to monitor evidence as it is published and will review and update guidance if necessary.
