I simply can't imagine why our dear leaders have not encouraged supplements like D, C, Zinc, Magnesium, etc . . . It's not like they're dangerous and they seem to have shown nothing but a positive effect on at least minimizing Covid's symptoms. I take a lot of supplements and have for years. Multivitamin, D, C, Zinc, Cinnamon, Turmeric, 1cc B12 shot weekly, Glucosamine / Chondroitin, Psyllium husk, 1/2cc iodine, krill oil, apple cider vinegar, faaaaaaaaack. . . I think there's more. Every morning and every evening. I know I've been exposed to Covid quite a few times. So far so good.
