I am currently taking a pro biotic called Sovereign Silver. It is colldial silver. I am taking a teaspoon a day and it says it will boost my immune system and fight off MRSA. I am using antibacterial soap and have sprayed the doorknobs, light swtiches, and faucets with bleach solution. I have also begun doing all of our laundry with color safe bleach. Please post any others you have tried and have had success with and stuff that hasn't worked.
