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.

SierraSil is a naturally occurring hydrothermal mineral complex from the Sierra Mountains that has been clinically proven to help support a healthy inflammatory response, gently detoxify and improve physical function. With extensive research in human clinical trials for both safety and efficacy with consistently positive results, SierraSil is the natural choice for proven joint pain relief.
