Since you're a "study reading"-type of guy
 Likely up your alley
- Yes, up my alley, but not my cup of tea. I made some improvements. Your turn? All the best, Bongo. Bongolian (talk) 06:08, 12 February 2017 (UTC)

 Speaking of "common cold" supplements
After my (late) discovery that the prestigious studies which showed the efficiacy of oral zinc supplementation for the common cold had since been retracted, I was atleast happy to see that Vitamin D recently got some major press on that topic. Here's the recent meta-analysis in question. Also, here's an interesting review article from a while back (2014).
These developments are especially interesting, considering Vitamin D is one of those rare vitamins which you generally benefit from by dosing a bit above the RDI. Examine put it well in the review I linked above:
|Overall, vitamin D is both cheap (roughly 5 cents for a daily dosage of 2000 IU) and safe (is not toxic except at absurdly high levels). While it may not fix everything, it has enough benefits to warrant taking. Vitamin D is cheap, safe, effective, and most people are in a deficient state. If you do not get enough direct sunlight exposure, supplementation is the prudent choice.|
Currently, I take 50ug Vitamin D a day (though not for any cold prevention reasons). Note also that I get like five minutes of direct sunlight a day (lmao). All the best, Reverend Black Percy (talk) 14:15, 5 March 2017 (UTC)
- Yes, it seems likely that above RDA vitamin D does have multiple beneficial effects. I take 2000 IU/day myself. There's no scientific consensus yet on raising the RDA though. Bongolian (talk) 18:36, 5 March 2017 (UTC)
 Mind taking a look
I've no idea if the guy is a concern troll or if he has legitimately excellent points. His sources, whatever they contain, use nice URLs (NCBI, Nature.com) if nothing else. But really, I've barely glanced at any of this.
Since you're well versed at this type of thing (and since I'm just about to slide shut the lid of my coffin and get to sleep before the dawn's first rays of sunlight char my ancient face), I figured maybe you could give the BoN's concerns a (re)view.
