Louie wonders whether the “D” in vitamin D stands for “Dog.”<\/p><\/div>\n

Vitamin D supplementation — critical in prevention and treatment of COVID-19?<\/p>\n

Or does it do nothing — except further enrich the vitamin and supplements industry, which is worth more than 100 billion dollars?<\/a><\/p>\n

The challenge is figuring out which of these is the truth, and after several weeks of thinking about the issue, I find it’s far<\/em> from straightforward — with many strong (and conflicting) opinions held by lots of smart people.<\/p>\n

I waded into these choppy waters a couple of months ago with this post after seeing a pre-print of a negative vitamin D study:<\/p>\n

Low vitamin D levels may correlate with worse outcomes in many diseases.<\/p>\n

But supplementing does not necessarily improve outcomes. In fact, it almost never does.<\/p>\n

(Still waiting for a truly convincing study in any infection.)<\/p>\n
