2630. To ask the Minister for Health if his attention has been drawn to further evidence (details supplied) demonstrating the effectiveness of vitamin D in lowering the risk and severity of SARS-CoV-2 infection; if NPHET has considered this further evidence; the steps he is taking to ensure that this evidence is reflected in public health measures; and if he will make a statement on the matter.

Evidence concerning the role of vitamin D and vitamin D status in relation to Covid-19, including the research referred to by the Deputy,  is maintained under regular review by the Department and has been considered as part of a series of evidence reviews.  In response to a request from the NPHET, the most recent evidence review conducted by HIQA of  interventions and health related factors that prevent COVID-19 infection or minimise progression to severe disease was submitted to NPHET on 12 May 2021 and published 23 June 2021 on the HIQA website. 

This HIQA review confirmed the previous NPHET assessment of January 2021 that there is currently no sufficiently high quality evidence to show that the use of Vitamin D supplementation prevents COVID-19 or reduces the severity of the disease.

The role of vitamin D in bone and muscle health is well understood and individuals are encouraged to follow the Department of Health Guidance accordingly.   Existing guidance on vitamin D was updated in November 2020 and advises that adults aged 65 and older should take a 15 microgram (600 IU) daily supplement for bone and muscle health.  The NPHET at its meeting on 28th January 2021 agreed that efforts should be made to increase awareness of existing guidance. Adults spending increased time indoors or those who are housebound or in long-term residential care or have dark skin pigmentation are also recommended to take a daily vitamin D supplement. These recommendations for the use of vitamin D have been incorporated into wider messaging, and  communicated across the health service, including nursing homes and social care settings, as necessary.
