IwastoldaboutJoint14withSierraSilbyafriendatskatinglastyear. I am 80 years old. I have taken cortisone injections in my (L) knee which worked for about a year but find taking SierraSil has made my knees and other joints much more supple. I golf and do yoga and was very pleased to find a Canadian-made product. I could order and not have to pay for shipping cost like US. I am already on my 4th bottle and hope you continue to supply it. I have told all my friends about it.
