What is the active ingredient?

The active ingredient in Joint Formula 14 is SierraSil, a clay-mineral sourced from a deposit in the Sierra Mountains with extensive clinical research for both safety and efficacy which has even earned the mineral two patents as a nutritional supplement for the treatment of osteoarthritis. SierraSil Joint Formula14 contains a variety of minerals, however, when examining the mineral content of SierraSil, it is important to consider that only minute quantities of each constituent mineral are actually released into the body upon ingestion. Therefore, Joint Formula14 cannot be considered a significant source of dietary minerals as the majority of the minerals in SierraSil JF14 remain in the clay matrix and pass through the body unabsorbed.
