For years I endured swelling and aches in both knees due to early injuries and subsequent stiffness. Knee replacements were the option offered by my doctor. I really didn’t want that until all possibilities were investigated. I had heard ads for SierraSil and decided I need to try it. Four day later, swelling was noticeably reduced, mobility restored to normal and aches controlled. I am back to walking 2 miles a day and enjoying life immensely. Thank you SierraSil. Life is good.

For 6 years I have been using SierraSil Joint Formula 14 and found it to be very effective in controlling my joint aches as well as lessening the stiffness of the joints in my fingers. The detoxifying properties of JF14 that helps clean the digestive system also is of interest to me. My recommendation is, GIVE IT A TRY.

I have been a very athletic person my whole life. I am always doing something outside. I am a fire fighter and co-owner of a Crossfit gym. I started using SierraSil Active about 1 week ago and already notice a huge difference in my hip. I have already recommended it to many of our members.

I have bad hips and have known they needed to be replaced since 1993. My doctor told me that I should live with them as long as possible as I was too young to have replacements. Recently the aches were beginning to be unbearable like a dull tooth ache. I had been waking up around 10 times per night because of the discomfort. I made an appointment with my doctor. to start the ball rolling on replacements. I had nothing to lose so I tried SierraSil Active. I only took 1 capsule each morning as I am not a big pill taker. Two days later, I had no aches and I was sleeping through the night. I cancelled my doctor appointment and after a month I am still feeling good with no aches. I have recommended it to some of my friends with the same outcome. Thank you for a good night sleep with no discomfort or aches

As a Dr. of Traditional Chinese Medicine, I am often presented with natural products to help treat and relieve joint pain. When I was recommended to try SierraSil with my patients, I decided to try it on my husband first. He had separated his shoulder more than a year ago, and though he had healed pretty well, he still had some residual pain. After only a couple of days SierraSil, he has already noticed he is able to do more during his workouts, without aggravating his shoulder, and it continues to improve.

Pet Chews were recommended to me by my local Nutter’s store as a good alternative to help my 10 + year old Golden Retriever, Billy. Billy had been becoming increasingly impacted by hip joint aches and immobility. He had started having difficulty getting up from a laying or sitting position.

We started him on the chews right away noticing that after a few days, he seemed to be moving with more ease and was more active. We knew he was feeling much better the day he tried chasing 3 rabbits!

I called SierraSil as I had wanted to purchase more chews but they didn’t seem to be available. I was relieved to hear the Pet Chews were being reformulated and will soon be available. After seeing the remarkable change in our beloved family pet, I want to able to keep him active. The Pet Chews are a great supplement to his diet resulting in a much-improved quality of life.

Our 11 year old dog, Rylie, was beginning to show signs of sore hips. She would not go for walks and had difficulty on stairs. We decided to try SierraSil Pet Chews after attending a seminar by the owner of the company. Within weeks Rylie was able to take short daily walks, climb stairs and even run again. This is a great product with no side effects.

In 2014, Winnie, our 9 year old black lab, was playing with our grandchildren in the back yard when I noticed she was favoring one of her back legs. I figured the kids had really got her going and maybe tired her old body out. She was still favoring it the next day. I had heard on the radio that someone had given SierraSil to their dog. So since I had SierraSil myself and it did wonders for me, I thought I would give it a try. The trying was to convince Winnie to take the pills. I tried mixing it in her food, that didn’t work. Bananas seem to work the best but the odd time, she felt the pill in her mouth and spit it out. After a couple of weeks, you could tell she was feeling much better and getting back to her old (young) self again. It was good to see.

In late fall of 2015, now 10 years old, she was again playing with the grandkids, but this time she slipped on some plywood I had used to cover the carpet on the deck for winter and injured her knee. We took her to the vet with our concern and were told she would need an operation but would be better to see what she would be like in 8 weeks with minimal activities. The vet prescribed some joint medicine that of course was very expensive and I explained to them about the SierraSil joint formula I had given to her before, that in my opinion was very helpful. We took Winnie home and immediately went on the net to see if there was a formula for dogs. To my surprise there was “SierraSil Pet Chews” tablets form and tasty, so no problem in getting her to take them. What a relief! Well as it turned out 10 weeks later she was back to herself. Maybe at some point she will still need that operation but for now she is back as usual playing with the kids. We now have her on a maintenance program of SierraSil Pet Chews to help with her aging joints. Winnie and I both thank SierraSil in enjoying her life to the fullest.

Jinx, our 7 year old cat would not chase his new 4 month old friend Casey (AKA Pinball) who for 1 year bounced around the house, off of walls, up the stairs and down again. Casey ran into jinx, over Jinx, under Jinx and could not get him to play. When I saw Jinx run around on his own, and chasing his brother for a couple of days I told my husband, who said two weeks earlier he’d started Jinx on SierraSil pet chews without my knowledge! I would never have believed the difference it made if I had not seen it with my own eyes. Jinx was having fun again!

We have been using SierraSil Pet Chews for our Sheltie, Sadie. She is now 13 years old and has stiffness from age and exercise. Since using SierraSil daily for the last 2 years, Sadie has improved dramatically and seems to be in less discomfort. She plays, sleeps and gets around much better. Thank you SierraSil!
