I started using SierraSil on Aug 26/2013. I had tried using “glucosamine” which was a powder but was still taking pain relievers every day. Since Aug 26 I have not taken any pain medication. Recently I noticed my blood pressure reading had dropped considerably. I am very pleased with the results I have gotten from SierraSil.
PS Earlier in 2013 an orthopedic surgeon had told me I needed both knees replaced !
