SierraSil Joint Formula14 is named after Sierrasil's promise to you: start feeling better in 14 days or less or your money back!
Sierrasil contains a pure, all natural mineral powder with essential minerals including calcium, iron and other trace minerals such as silicon, potassium, magnesium, manganese, copper and zinc. Research shows Sierrasil helps to ease joint and muscle aches, reduces stiffness and prevent cartilage breakdown associated with exercise and movement. Sierrasil Joint Formula 14 has health promoting and detoxifying properties because of its rich clay mineral structure.
SierraSil is unique in its source, its combination of minerals, and in its benefits. SierraSil contains a rich complex of minerals with unique properties unlike any other complex known. Dr. Haydn Murray, a renowned mineralogist, conducted an x-ray diffraction analysis of SierraSil; he reported: "In my more than 50 years of mineral research, I have never seen a combination of minerals like this before."
SierraSil is unique due to its mechanism of action, which supports cartilage integrity through gene suppression.SierraSil is also one of the few joint support formulas on the market that works for most users and does so typicaly in less than two weeks, is vegetarian and has voluntarily been extensively tested for safety.

Sierrasil Frequently Asked Questions
Why do you recommend increasing water intake?
Drinking at least 8 glasses of water per day keeps you hydrated and will complement the benefits of SierraSil. It is important to keep your body hydrated to ensure cardiovascular health and promote gentle detoxification properties of SierraSil.* This will result in better absorption of vital nutrients.
Why do I have to take SierraSil on an empty stomach?
SierraSil’s composition naturally promotes absorption of the minerals.* When taken with water on an empty stomach, SierraSil has a pH of about 3.5, which allows the beneficial minerals to be easily ionized and presented to the tissues to simultaneously replenish mineral deficiencies and support metabolic balance.* It is very important to always take SierraSil on an empty stomach. If taken with food, medications or supplements the clay component of SierraSil will become bound to food components such as fiber, phytates and phosphates, as well your medications or supplements and will not be absorbed into the body but will instead pass right through with all the contents its intact. If taking SierraSil with food and medications the maximum intended benefits will not be realized because the proper concentrations were not absorbed into the body.
Who should take SierraSil?
SierraSil is recommended for people from all stages of life – adults desiring joint support, seniors seeking to maintain independence through support for joint function; active people and athletes wanting to increase workout intensity; and anybody looking for a daily trace mineral supplement.
When will I start to enjoy the benefits of SierraSil?
Clinical research shows that people using SierraSil can start to feel better anywhere between a few days to a couple of weeks. It is important to note that the minerals in SierraSil start to work in the first 2 hours after taking your daily serving. For some individuals it may take longer than the first bottle.
What is the recommended dosage of SierraSil?
For best results take the SierraSil capsules with only water, together (at one time) and away from food. Food or other beverages such as coffee, tea, juice or milk should be taken at least one hour after, or 1 hour prior to SierraSil. Take medications and supplements –at least 4 hours before or after SierraSil. SierraSil supports gentle detoxification due to its rich clay mineral composition therefore it is strongly recommended drink a minimum of 8 glasses of water per day.

Should I continue to take other joint care products?
That is up to you. Some joint care supplements provide ingredients a healthy body already makes and therefore may not be necessary; others may complement the benefits of SierraSil. Most consumers find SierraSil provides a sufficient level of benefits that they do not need to take other joint care products. That said SierraSil alone is not a substitute for healthy living. To compliment SierraSil’s effectiveness we recommend a diet of wholesome foods, including plenty of fruits, vegetables, whole grains and essential fatty acids. Avoid or reduce highly processed foods. Healthy lifestyle choices include regular exercise, a full night’s rest and reduced stress.

Sierrasil Clinical Study
SierraSil has been subjected to a rigorous level of testing and analysis. From these extensive assessments, experts agree that SierraSil is safe and effective and promotes joint health and function.*
1. HUMAN CLINICAL STUDY
A multi-center, double-blind, randomized, placebo-controlled study of more than 100 patients needing joint support was conducted at four different servings (three with SierraSil, one with placebo). This study was published in a peer-reviewed journal.
Internationally Registered, Multi-Center, Randomized, Double-Blind, Placebo-Controlled Trial #ISRCTN38432711. PUBLISHED: The Journal of Inflammation.
RESULTS: This study provides clear evidence that SierraSil, at 3 and 2 capsules, may provide some joint support within two weeks of daily use*.
2. MECHANISM OF ACTION STUDY
This test was undertaken to determine how SierraSil worked on human cartilage in-vitro. The test demonstrated that SierraSil promoted cartilage health, measured by the reduced amount of degraded cartilage debris, as glycosaminoglycans (GAG) release.*
Miller, Mark J.S., Ahmed, S. et al. 2004. Suppression of Human Cartilage Degradation and Chondrocyte Activation by a Unique Mineral Supplement (SierraSil) and a Cat’s Claw Extract, Vincaria®. Journal of the American Nutraceutical Association. Vol. 7. No. 2:32-39.
3. HUMAN PILOT STUDY
SierraSil was tested to determine if it safely provided significant support to knees*.
WOMAC (Western Ontario and McMaster Osteoarthritis Index) scoring.
4. DISSOLUTION TEST (BIOACCESSIBILITY)
A sample of SierraSil was tested to determine the bioaccessibility of minerals.
RESULTS: The bioaccessibility of aluminum, lead and iron was found to be very low.
Protocol: US Pharmacopeia 24 Method 711
5. SUB-ACUTE ORAL TOXICITY STUDY
A daily serving of SierraSil up to 1,000 mg/kg (35 times the recommended serving) for a period of 90 days was tested.
RESULTS: SierraSil did not cause any adverse responses at the highest level taken.
Protocol: OECD No. 408
The consistent outcome of the lab, invitro and human clinical trials are that SierraSil is a safe and effective way to support joint health and function*. Research also shows that the benefits of SierraSil are usually felt within 14 days or less.
As a chiropractor for almost 40 years (I am 64 years old), I have used many formulas for joint health and SierraSil seems easily the most effective. “
- Dr. Tom Close DC, Monument, CO
I began using Sierra Sil personally to see if it would help. Before using Sierra Sil I was unable to run for more than fifty yards. After using Sierra Sil for about two months I was able to run as far as my 60-year-old heart would take me (about 5K)! I began recommending Sierra Sil to my patients and the results have been impressive. There are very few people who either cannot take Sierra Sil or do not notice any benefit, but the vast majority find it very helpful. The demand has become so great I have trouble keeping it in stock. I recommend it without reservation.
- Dr. Rod Thompson, Winnipeg, MB
The results are incredible!
- Dr. Charles Rassel, D.C. Escondido, CA
I am dedicated to use natural products whenever possible. I really do like SierraSil, I use the topical spray on each patient, they love the way they feel and smell after a treatment.
- Dr. Genieve Burley, D.C. Vancouver, BC
My patients have found that SierraSil works effectively. It’s amazing! In 2-3 weeks they get responses – I’m very pleased with it.
- Dr. Clem Williams, West Vancouver, BC
I read the book on SierraSil and wanted to try it. I gave a bottle to a 79 year old male patient who agreed to let me know in 3 weeks how he felt. In 3 weeks he advised me to get another supply. Now many grateful patients come to my office asking for it.
- Dr. Delford Roth, Scottsbluff, NE
I conducted a review of SierraSil and then assessed results on a first hand basis with patients. Consequently, I have decided to make SierraSil a recommended product. The results continue to reflect what I observed in my first review, namely a high rate of efficacy.
- Dr. John Diamond, Intemedica, Reno, NV
The experience of my patients at Health Medicine Center in Lafayette, California on SierraSil is one of a consistent performer. I receive comments about “surprising” and “great results” from athletes, middle-aged weekend warriors, golf and tennis buffs, and former marathoners whose knees and hips have taken a beating. Whereas supplements featuring glucosomamine and chrondroitin sulfate often requires two to three months of use. SierraSil demonstrates effectiveness within a short time.
- Dr. Meg Jordan, LaFayette, CA
I have been using SierraSil for 4.5 years and give out 20-30 pamphlets a day to my patients. The response from my patients is overwhelmingly positive.
- Dr. Michael Caplan, M.D, Ukiah, CA
I am 34 years old trying to have an active lifestyle. I usually practice Crossfit and play squash several times a week and I can see now SierraSil is making a huge difference in my life. Before using SierraSil, I was sore and stiff almost every day specially in the mornings (morning stiffness).I remember once it took me a couple of minutes just to get up from my bed and walking to the shower. I have to confess that it was not a very pleasant sensation. After taking SierraSil, I noticed that I am not as sore as before and my recovery time between games or training is less. When I’m playing tournaments I try to double the dosages and it makes a difference the next day!
Taking SierraSil is part of my daily routine and I highly recommend for people who wants to keep active life style and worries about next day soreness.
- Ricardo S. Vancouver BC
I used SierraSil to help with an old shoulder injury from football and continue to take it daily as it’s the best product I’ve found for recovery and eliminating post exercise stiffness.
- Tommy Europe Celebrity Personal Trainer
I started using SierraSil over the summer and almost right away I noticed a difference in my recovery from workouts. This year with lockout it really helped as we were working out so much longer than normal. When I signed in Europe I took some with me too, and some of my teammates in Europe even started using the spray.
- Dale Weise Vancouver Canucks
New Westminster Senior Salmonbellies Lacrosse Club
Our players took SierraSil during the 2010 Mann Cup Finals in Peterborough, Ont. In combination with our post-game recovery regime, the product assisted in helping our players recover following each game, as games were played consecutively. Players were able to report reduced muscle soreness in comparison to previous years. New Westminster Salmonbellies highly recommend SierraSil as a part of your regiment for muscle and joint relief. Our Club is definitely going to be using SierraSil for all of the 2011 Season.
- Steve Mah Physiotherapist
With SierraSil, my body did not feel beat up from the heavy pre-Olympic training
- Bill Schuffenhauer US Bobsled Team
As a double below knee amputee and member of the Canadian National Sitting Volleyball Team, I find that SierraSil allows me to overcome the aches and pains that come from the on court pounding my body takes from playing this sport and the added off court training that comes with it. SierraSil provides me the opportunity to recover quickly from the rigors of training and remain mobile day in and day out.
- Dave Merchand CND Sitting Volleyball Team
In order to stay healthy, I take vitamins daily, but no other supplements. However, a teammate convinced me to try SierraSil this summer, and I haven’t looked back. It helped me feel even more healthy going into training camp. I also like the that SierraSil is Informed-choice certified, meaning its third party tested to be free of banned-substances.
- Evander Kane Winnipeg Jets
Our players are our most important asset, and keeping them in game shape in my priority. SierraSil Joint Formula 14 and Topical Spray help players perform their best.
- Bill Reichelt Head Athletic Trainer BC Lions
My name is Joe Resendez and I am the head athletic trainer for the 2010 NBA Development League Champions, the Rio Grande Valley Vipers. I used up the samples provided by SierraSil on our players and was really impressed by the results. Some of our players felt energized and felt less soreness after games. It really shortened their recovery time between games. I would have no reservations using your product again, for our entire time.
- Joe Resendez Athletic Trainer
When I heard about SierraSil and started taking it, I noticed in two weeks that the pain was relieved and alleviated. I now enjoy tennis and golf without pain. I recommend SierraSil for everyone who suffers with joint discomfort. I am a SierraSil user for life and you will be too. Try it today.
- Lem Barney NFL Hall of Fame
I suffer with joint issues in both knees which makes walking very difficult at times. I was pretty close to needing knee replacement surgery. A friend introduced me to SierraSil and I’ve been on it for just over one month. I noticed a difference after just one week and the results have been nothing short of remarkable. I have my mobility back, I can walk relatively ache free – I can even get back into yoga and hiking.
Amazing – and it’s all natural. WOW! Thanks.
- Lola P. Saskatoon
Last winter I developed discomfort in my leg and I was unable to walk more than 15 minutes before having to stop, stretch and sit down. I was told that my problem was related to my hip and eventually I would require surgery. After taking SierraSil I have noticed a big plus improvement and I can now walk for an hour. I am very satisfied.
- Allan G. Toronto
I have been suffering with back and neck discomfort for many years “off and on” and some knee discomfort. Since I started taking SierraSil, my discomfort has diminished and some days , there is no discomfort at all. It took about 30 days of usage before I saw any results but it is a product that I have recommended to my friends.
- Anita G. Toronto
Shoulder discomfort was a daily reality for many years. Chiropractic, messages, S bar used for pressure, till I heard on the radio about SierraSil, started to use 3 a day in the AM on empty stomach (is key!) 5 years ago. A week later, no more shoulder discomfort period! What a relief.
I tell everyone who is suffering with issues with legs, arms, etc.
- Jane T. Merritt
I have joint discomfort in my hands. In the morning I can’t bend my fingers, within 15-30 minutes they don’t hurt and I can bend them.
- Julie K. Toronto
One year ago I could barely hold a cup of coffee because my hands ached so much. I was wearing compression gloves all the time. Since taking SierraSil I now can sew, crochet and write. Things I haven’t done in 5 years. Thanks!
- Marilyn T. Toronto
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 !
- Nancy A. Ontario
This is my testimonial with regard to the use of Sierrasil. After turning 65, I noticed aches symptoms in both my ankles. Not a big fan of over the counter pain medication, I thought there was no relief for me. It was very painful to walk. Being a very active person, I wanted to find a natural solution to my problem. In walked Sierrasil. Not only did Sierrasil free me from my ankle joint aches, I also noticed that my restless leg syndrome was vanished. I am so grateful for this supplement. Now my wife and I enjoy long walks together, free from aches. I rest easy without having to get up several times a night because of restless legs.
Thank you Sierrasil!
- Maas Alberta
I have been using SierraSil Joint 14 for 2 years. I was supposed to have hip replacement. But after using this I am not going to have it. My hip and I can’t get over how it has helped so much. I advised several people to take it and they had same results.
PS My niece needed knee surgery and she had same results as myself.
- Audrey D. Calgary
My grandmother was having joint knee discomfort for a while now. I recommended for her to take SierraSil Joint Formula and the pain reliever spray to help her.
She started taking both and she found that it was helping. When she went to her doctor to get a follow up appointment for her knee, she took SierraSil products to the doctors to see if this was ok to take. The doctor recommended that she never stop taking the Joint formula because it is going to help her. Its been three months and she is still taking it.
