There is an interesting one page article in the Lancet which looks at the current evidence and also new work being undertaken to study Vitamin D status and Coronavirus outcomes.: Vitamin-D and COVID-19: do deficient risk a poorer outcome? You can read it here….Original research from our NHS Vitamin D LaboratoryTwo pieces of our own vitamin D research are of current interest. One considered our local inner-city population in 2006 and showed important ethnic variation in vitamin D levels. A second looked at unexpectedly high Vitamin D levels found in some members of the public checking their vitamin D levels with our home testing service. Both papers can be down loaded here…..
Podcast looking at Vitamin D and Coronavirus
Sarah Boseley, Health Editor of the Guardian, talks to Professor Susan Lanham-New, Head of Department of Nutritional Sciences at University of Surrey, about vitamin D. After a general introduction, the lack of direct evidence for a role of Vitamin D in Covid-19 is highlighted and the ongoing work to look at this considered. Vitamin D level optimisation in the population is strongly supported by Susan, with advice to take supplements but NOT taking large doses, which could be harmful.

Consensus Statement - BMJ
Vitamin D and SARS-CoV-2 virus/COVID-19 disease
This brief report by UK and other experts provides a balanced scientific view on vitamin D and SARS-CoV-2 virus/COVID-19 disease. The article points to the importance of Vitamin D and also that many in the population have low levels and summarises as follows: “Taking a daily supplement (400 IU /day (10 µg/day) in the UK) and eating foods that provide vitamin D is particularly important for those self-isolating with limited exposure to sunlight. Vitamin D intakes greater than the upper limit of 4000 IU (100 µg) per day may be harmful and should be avoided unless under personal medical/clinical advice by a qualified health professional.” The full report with excellent links to web based referencing is found here….

Vitamin D for COVID-19: a case to
Lancet Diabetes & Endocrinology, 3rd August 2020“…… Pending results of such trials, it would seem uncontroversial to enthusiastically promote efforts to achieve reference nutrient intakes of vitamin D, which range from 400 IU/day in the UK to 600–800 IU/day in the USA.” Read here…
A Basic Review of the Preliminary
Evidence that COVID-19 Risk and
Severity Is Increased in Vitamin D
Frontiers in Public Health - Accepted for PublicationThis paper concludes: “The literature review also found that prophylactically correcting possible vitamin D deficiency during the COVID-19 pandemic is extremely safe. Widely recommending 2000IU of vitamin D daily for all populations with limited ability to manufacture vitamin D from the sun has virtually no potential for harm and is reasonably likely to save many lives.
