Steve, fantastic effort to get the real solution to Covid with Vitamin D3 and Zinc stockpile. However, this is only 2/3 of the solution. Zinc has problems getting into the cell to fight Covid, so there needs to be a Zinc ionophore to help it get in the cell. Quercitin is a Zinc ionophore and if you add that to the program, it will be much more effective. Contact Richard Pearl at 954-741-4045 at his health food store to get more info about this.
