In the January 3 COVID-19 podcast at around the 33:50 mark, Peter makes some comments about supplemental vitamin D as a "surrogate of health through other means" and that "(his) take on that has been not to prescribe vitamin D and instead to get outside and exercise and get it that way." Has this recommendation for patients been limited only to the context of vitamin D for COVID prophylaxis? Or is Peter speaking more broadly of recommending sunlight exposure over vitamin D supplementation in general? Clarification would be appreciated. Thanks so much.
