Marc Kennedy, 2016 Briar and World Champion of Curling*
"I have felt the incredible benefits of SierraSil after only a couple of weeks! The joint pain in my right hip and knee caused from years of competitive curling and repetitive stress is gone. I feel like my joints are 10 years younger. My need for over the counter anti-inflammatory drugs has disappeared, I only wish I would have discovered this product years ago."
