"Colloidal Silver" has been used since the late 1800's in countless applications, and encompasses a wide variety of silver products. Many contain (claimed or unclaimed) salts, proteins, compounds or stabilizers - all of which affect the safety and efficacy of silver.
Bio-Active Silver Hydrosol represents the ultimate refinement of the colloidal silver category. It contains 98% positively charged silver, in pharmaceutical-grade purified water. Our unique silver species, with a verified and unmatched particle size, remains in its most active state for use within the body.
