In my practice, I prescribe botanicals, nutraceuticals and supplements. However, due to the nature of the SARS cov-2 virus, for now, hold off on supplementing with vitamins A and D beyond 1000 IU’s and with the propolis bee spray and royal jelly. These have a modulatory effect by their nature in human biochemistry – meaning they can up-regulate or down-regulate a function based on what is needed. The effect of the virus on these vitamins is they can actually turn inflammation on to a level the body cannot manage effectively. You may continue to eat foods that have these vitamins in them.
