Thread of reviews/evidence appraisals concerning a link of Vitamin D (deficiency) and COVID-19 (susceptibility to infection w/ SARS-CoV-2, severity of disease &c.), late September 2020 ed. #pland #vitd #vitamind #covid19
"The Facts: Vitamin D and Coronavirus"; a compact (4½ page) review by a (now) 15-strong group of independent researchers, doctors and scientists, highlighting the current top evidence (bonus: poster): http://bit.ly/vitd3info
"Low Vitamin D Worsens COVID-19 Risk" by @KarlPfleger, an excellent review (which has been around since May and, thankfully, still receives updates; bonus: PDF 1-pager): http://agingbiotech.info/vitamindcovid19/
"A Basic Review of the Preliminary Evidence That COVID-19 Risk and Severity Is Increased in Vitamin D Deficiency", an extensive review (K. Pfleger: "tour-de-force") by Linda Benskin, now peer-reviewed and published in (open-access) Front. Public Health https://www.frontiersin.org/articles/10.3389/fpubh.2020.00513/full
"Vitamin D & other nutritional supplements to protect against severe COVID-19 symptoms", a book-length (160 pages!) review/call to action/collection of materials by @RobinWhittle3; most useful (to me) the section w/ synopses of the latest research: https://aminotheory.com/cv19/#lr
(Robin Whittle also operates the NISH [Nutrition for Immune System Health] mailing list [which everyone who read as far as here will probably find interesting, too]: https://nish.groups.io/g/main )
Last (for now), but not least, @GShotwell's literature review on GitHub: https://github.com/GShotwell/vitamin_d_covid
