This thread is for the discussion of Vitamin D.
Peter Bergman, Anna-Carin Norlin, Susanne Hansen, Rokeya Sultana Rekha, Birgitta Agerberth, Linda Björkhem-Bergman, Lena Ekström, Jonatan D Lindh, Jan Andersson. Vitamin D3 supplementation in patients with frequent respiratory tract infections: a randomised and double-blind intervention study. BMJ Open, 2012; 2: 6 e001663 DOI: 10.1136/bmjopen-2012-001663
Paul Bergner's summary of the above article from his twitter: "Vitamin D 4000 iu/day for 1 year reduced colds by 25% and antibiotic use by 50%".
The Vitamin D Council in particular is a good resource and they offer a home testing kit.
The Weston Price Foundation has some valuable reads (although do keep in mind that their paradigm of high Vitamin A with Vitamin D differs from the Vitamin D council and it's not clear which proposal is more accurate):
