Silver is one of the many minerals that our bodies need to function properly. Before our soils became severely depleted of minerals in the 20th century, the average daily intake of silver was approximately 50- 100 micrograms. Today, the typical American diet contains approximately 85% less silver and other trace minerals than it did 100 years ago. Taking one teaspoon of Mountain Well-Being Colloidal Silver will supply 75 micrograms of silver. The EPA states that it is safe to ingest 350 micrograms of silver each day. This is the safest and most effective Colloidal Silver available! It is electrically produced in small batches utilizing state-of-the-art technology and .999% pure silver. We use laboratory grade, ultra pure water that is specially structured to more efficiently accommodate a greater surface area of silver.
