"In my opinion, ProTren is the best quality, most effective probiotic line available. My wife Toni had a one-year bout with major G.I. issues and we tried every probiotic company from A-V –including individual and combination strains. ProTren was the only truly effective line that helped her. I receive no remuneration, free product or benefit from endorsing ProTren in any form whatsoever, and, in fact, have never endorsed any company or product before in my 35 year history of preventative medical work."

"I am a board certified dermatologist who serves as the Program director for the Dermatology Residency training Program at the University of Alberta in Edmonton, Alberta, Canada. I am also the Founder and Medical Director for the Acne Clinics of Canada. I have found your probiotics to be extremely helpful as an adjunct to many medications I currently use to combat skin diseases. I applaud you for being a pioneer in your growing field and thank you for providing such quality products to the marketplace. Our experience at the University of Alberta has been nothing short of stellar and we will continue to use your probiotic products to assist in the care of our patients."
