Trump attacked for taking hydroxychloroquine but no one mentions Zinc

Why can these reports not actually get out word of a proven aid for preventing covid19.... a strong immune system through nutritionaly optimization... take zinc tell people to get their full intake of zinc as much as their body can absorb. Stop attacking a choice of preventative medicine, and start promoting nutrtion as the first point in nursing a healthy body, good air, good water and good food that are healthy and will promote health.
