“As an integrative physician, I am faced each day with patients hoping to feel better, have more energy, and lower their risk of chronic disease. The implementation of ProLon into my medical practice has been a wonderful addition to the therapeutic options I can offer. The fact that it utilizes the body’s natural healing pathways to support health, has resulted in my patients enthusiastically embracing this unique program.

I highly recommend that every medical practice incorporate ProLon … and witness for themselves the many benefits it provides to patients.”

Felice Gersh, M.D.

“The ProLon plan is well organized, easy to follow, and well balanced throughout the day. It’s been more than three weeks since we’ve done it and we still feel the effect in terms of reduced appetite and stronger self-control. And we both kept the weight off so far and plan a second cycle soon.

As a result of my positive personal experience, I’ve recommended ProLon to almost 20 patients – including a few pre-diabetics or diabetics – over the last three weeks. Everyone who has completed the 5-day regimen has lost weight and it was a positive experience for all.

I plan to use ProLon to help patients kick start and adopt a healthier lifestyle.”

Thank you!

“I have become a huge cheerleader for the product. I have now dropped 14 pounds and going.  I have stayed on a very healthy diet after my first ProLon as it was the springboard for my transition to health and happiness.  I had my blood test done pre and post and the results are very encouraging and I wasn’t unhealthy to start.  I can only imagine the effect L-Nutra can have on someone who needs this more than I did.”
