*These are individual results. Your results may vary.

Dr. Delford Roth – Scottsbluff, NE*

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.

SierraSil has been effective. Due to its safety index, we can confidently recommend this product as a stand alone for suitable patients or as an adjunct to other treatments.

Dr. John Diamond, Intemedica – Reno, NV*

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. Meg Jordan – LaFayette, CA*

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. Michael Caplan, M.D. – Ukiah, 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.

I’ve been recommending SierraSil and I’ve seen some excellent results. I’ve found that SierraSil is one of the best options available. Seldom have we found an ingredient as effective as SierraSil.

Mike Gillis, President, General Manager and Alternate Governor of the Vancouver Canucks*

Over the past several months, our trainers have been using SierraSil with some players and to date have been very pleased with the results.

Don Hay – Vancouver, BC*

“Staying in shape isn’t as easy as it used to be. SierraSil frees me so I can feel great.”

Marty Reasoner, retired NHL player*

Back in 2003 I went through 2 knee surgeries. I needed to take every advantage I could to return to NHL and compete at that level. Through hard work during the off-season and the help of SierraSil® I have not missed a game in 2 years. I recover much faster between games. I completely recommend this product. SierraSil makes a difference, no question about it.

Anthony Toth – Vancouver, BC*

Five seconds can make a world of difference in a race, yet alone 5 seconds every 100 meters. Since trying SierraSil Joint Formula14, I have been able to train harder and get quicker. It’s the reduced recovery time that I feel most. Now if SierraSil JF14 can help me, already in exceptional physical condition, imagine what this natural mineral complex can do for you.

Harlen Lahti, President and Owner, Finlandia Pharmacy and BioMed International*

Dear Michael,

As you know, I’ve been a pharmacist a long time, even before I opened Finlandia in 1972 with a passion to help de-medicalize consumers, especially seniors, due to a growing dependency on prescription and OTC products for maintaining quality of life, irrespective of the potential health risks.

That’s why, when we learned about SierraSil™ through mutual friends back in 2004, we were pleased to see your commitment to validating the safetv and efficacy of SierraSil through clinical and other research, and for Finlandia to be the first retailer of the product. For most of the time since, I have personally be using SierraSil Joint Formula14 and most recently also trying Joint Formula Active with Meriva™ and SierraSil.

In my opinion, SierraSil, the mineral ingredient, doesn’t have any peers despite the competing claims of many products. SierraSil is truly unique in its activity and function, even if we don’t know fully how it works. Yes, there is evidence of calming inflammation due to age, activity and health conditions, of reducing cartilage breakdown, of binding heavy metals permitting their excretion, and as you have shared with me from recent research, some muscle and sport benefits. But there is likely more to it thari that, so I encourage SierraSil to continue its commitment to research. In time, I think the role of chelating minerals will be better understood by the medical community and population at large. Despite low absorbability, these minerals are essential to optimizing health in diets and environments plagued by less than optimum nutrition and quality, and unfortunately, that is true for most us.
