It aims to prevent vitamin D deficiency among specific population groups including infants and children aged under 4, pregnant and breastfeeding women, particularly teenagers and young women, people over 65, people who have low or no exposure to the sun and people with darker skin. 

In August 2017, this guideline was updated after publication of The SACN vitamin D and health report 2016. We have amended the definition of at-risk groups, updated links to the new report and updated reference nutrient intake details.

Guideline development process

How we develop NICE guidelines

This guideline updates and replaces recommendation 3 in NICE guideline PH11 (November 2014). In addition, in NICE guideline CG62 recommendation 1.3.2.4 has been updated so that it is in line with this guideline.

Your responsibility

The recommendations in this guideline represent the view of NICE, arrived at after careful consideration of the evidence available. When exercising their judgement, professionals and practitioners are expected to take this guideline fully into account, alongside the individual needs, preferences and values of their patients or the people using their service. It is not mandatory to apply the recommendations, and the guideline does not override the responsibility to make decisions appropriate to the circumstances of the individual, in consultation with them and their families and carers or guardian.

Local commissioners and providers of healthcare have a responsibility to enable the guideline to be applied when individual professionals and people using services wish to use it. They should do so in the context of local and national priorities for funding and developing services, and in light of their duties to have due regard to the need to eliminate unlawful discrimination, to advance equality of opportunity and to reduce health inequalities. Nothing in this guideline should be interpreted in a way that would be inconsistent with complying with those duties.


Commissioners and providers have a responsibility to promote an environmentally sustainable health and care system and should assess and reduce the environmental impact of implementing NICE recommendations wherever possible.
