Comments by "Toby" (@toby9999) on "Low vitamin D and increased deaths" video.
Are there any peer reviewed clinical trials around vitamin D? I believe vitiman D is useful in my case because my vitiman D level was extremely low but that's a personal thing. Authorities can't recommend without credibal supporting evidence. A recommendation from Joe Rogan or Dr. Campbell isn't enough.
