My mother in-law had a sinus infection 4 days she knocked it out completely!
She only used one a day. Could you imagine how fast it would have knocked it out, upping her dose to 2-3x a day!
My husband works in the grocery business, a very well-known place full of germs! This last winter fellow employees had been getting the flu, bronchitis, colds, upper respiratory infections, etc. He still has not gotten sick! This is amazing I recommend it to everyone!
My kids also love defend! We make popsicles and keep a pitcher in the fridge!
