SierraSil

SierraSil helps support your joints and body. 

In the early 1970s, a prospector was looking for gold in the high Sierra Mountains. What he found instead was natural clay that sparkled like gold when exposed to sunlight. The prospector had discovered something even more valuable than gold: SierraSil®.

Active adults, seniors and professional athletes around the world use it to support back, knee and joint function and to enhance energy and endurance.
