Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, whether he has assessment the potential merits of workplace-based vitamin D supplementation programmes as a mechanism to reach populations at higher risk of deficiency.

The Scientific Advisory Committee on Nutrition (SACN) is currently conducting a rapid review of whether current vitamin D recommendations for vitamin D intake and status are adequate for people with higher melanin concentrations. The vitamin D working group is reviewing relevant evidence and discussions are ongoing. In line with the usual SACN process, minutes of the SACN vitamin D working group meetings, along with minutes of all SACN meetings, are published on the SACN’s website. The SACN aims to publish conclusions of the review later in 2026. Ministers are informed of SACN publications and risk assessments and receive separate advice on potential subsequent policy options.

For people at risk of not receiving enough vitamin D during the summer months we recommend they consider taking a daily supplement containing 10 micrograms of vitamin D throughout the year. Advice is available on the National Health Service website for everyone, including pregnant and breastfeeding women, to consider taking a daily supplement containing 10 micrograms of vitamin D during the autumn and winter. Our focus is on ensuring that vitamin D policy prioritises interventions with the greatest public health impact. We have therefore not assessed the merits of workplace-based vitamin supplementation programmes and are not currently planning any additional action to introduce targeted vitamin D supplementation programmes. Any further risk management approaches will be considered once SACN has completed reviewing the evidence and made recommendations for people with higher melanin concentrations.

The National Diet and Nutrition Survey is designed to provide data on the diet and nutrition of the general United Kingdom population. The survey design means that oversampling of ethnic minority groups is challenging. However, a recent increase in the number of blood samples collected annually in the survey means we expect to be able to analyse and report vitamin D status by ethnicity by combining data collected from 2024 to 2029.
