For more than a year, Dr. Campbell has been providing near-daily updates about the pandemic and the medical science behind it. Combining a folksy wisdom with deep expertise and a long career in medical education, Dr. Campbell has amassed an audience now approaching one million viewers.
He was an early champion of the efficacy of Vitamin D as a public-health measure to reduce illness and death from SARS-CoV-2, and he follows the issue closely as more evidence becomes available. He is careful to say that he cannot prescribe for you, but he’s also forthright about sharing his own dosage (now up to 4,000 I.U. per day).
For me, Dr. Campbell’s comforting and knowledgeable voice will always be the soundtrack of these times.
