I am 79, and have suffered from arthritis, fungal nails, and the odd bout of diaorrhea/stomach upset for some years, and bought your colloidal silver some 5 weeks ago to see if it would help my stomach/bowels and have been taking a teaspoon in water each day since. Not only have my digestive symptoms disappeared, but my fungal nails have cleared up, and my arthritis in knees and hips has taken a major turn for the better. I can now walk comfortably for some 400 yards without having to sit, instead of needing to find a seat every 50 yards. I am amazed and delighted with your product. Thank-you!
