You also need Zinc, Vitamin C, Vitamin D (with a meal, it is fat soluble and is completely ineffective on an empty stomach). Quercetin (over the counter) or Hydroxychloroquine are zinc ionophores that vastly improve cellular zinc uptake. For men in particular- if you have any prostate issues or have family members with prostate issues, they are very likely strongly associated with a dietary zinc deficiency.

If you are currently ill, call your doc to add an antibiotic like Doxycycline or Azithromycin as recommended as well in Dr. Peter McCullough's protocol. Here's one of the earlier videos of his recommendation, you can find the updated doses- I think they increased the IVM dose like a year ago, but I'm too lazy to look it up right now. https://www.youtube.com/watch?v=cxmhvZ6eEI4&ab_channel=AssociationofAmericanPhysiciansandSurgeons
