“Zinc is the bullet – it kills the virus. The only problem is the bullet doesn’t get to the place where it needs to be. The virus is inside the cell. The enzyme is inside the cell. And the zinc on its own cannot get into the cell. You have a bullet without a gun – useless. Now, it turns out there’s a class of medications called ‘zinc ionophores’ or a class of substances called ‘zinc ionophores’ — what they do — is they open up a channel, a door, which allows zinc to go from outside the cell to inside the cell . . . . . . They’re the guns that shoot the bullet. The bullet then gets into the cell and stops the virus enzyme from helping the virus replicate. So you have a gun and bullet. Only the synergy of the two creates a functioning unit . . . . . . Patients were having trouble sourcing it, because it was four different ingredients that weren’t always available in the same place. They had trouble finding the right doses. It was a puzzle that was a little too complex for people to put together. So I was asked as a necessity — as a favor to people — to produce something that has everything in one package. It made sense to me, so with the help of my colleagues, we were able to produce a substance — a compound called Z-Stack — that has Vitamin C, Vitamin D, and most importantly has quercetin and zinc.”
