I am sending you this letter to let you know how your “SierraSil Joint Formula 14” has been helping me. In February 2014, I found out I have osteoporosis in my left knee.  My husband heard from a friend at work about your product. He went out and got me to try. I tried them. And since I have been on them and using them my left knee has been pain free. I am a senior. I am 64 years old.

A few years ago I started taking SierraSil for my knees. Within a few weeks I noticed a difference. Sorry to say, life got in the way and I stopped taking SierraSil for about 6 months. My knees cracked again. I am taking SierraSil again and have learned a valuable lesson. Don’t stop SierraSil.

I have a 5 year old black-chocolate lab. When she was young she hurt her front shoulder. She was often lethargic and stiff. Since giving her 2 capsules in her food she is running, jumping and is very puppy like. Thank you for helping her.

I was told about Joint 14 with SierraSil by a friend at skating last year. 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.

I am a golf professional and very active and on my feet a lot. I have had a lot of discomfort in both my ankle joints and affter 1.5 weeks taking SierraSil, the discomfort is gone. I will continue taking it daily and recommend it highly to anyone experiencing joint discomfort.

Thank you SierraSil !

In 2006 my Dr. told me I would need a knee replacement within 6 months to a year. Upon hearing about Sierrasil I started taking 3 tablets each morning and I don’t have any problems with my knees, hips or other joints. I continue to use it. I am now 81 years old and maintain my own yard. No surgery to this date.

I also take Sierrasil and enjoy discomfort-free knees and hips. I swear by Sierrasil, as I have had no problems with my joints. I am now 74 years young. It’s a great product. I am very satisfied with it.

I had heard all the commercials and had several patients ask my opinion on SierraSil so I decided to try it myself.  10’s of 1,000’s of adjustments per year for 17 years in practice has taken its toll on my hand and finger joints.  Morning stiffness and soreness is not uncommon. After 10 days of taking SierraSil there was a noticeable improvement!  It worked for me and I’m confident it’ll work for you!
