“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.”

“The ProLon plan is well organized, easy to follow, and well balanced throughout the day. My fiancée and I have done it multiple times over the past few months already, with amazing results. The effect of reduced appetite and stronger self-control lingers on for weeks after each cycle. He lost over 15 pounds of fat while I lost those last 4-5 pounds I wanted to lose for a while. And we both feel great!

As a result of my positive personal experience and the compelling scientific research behind it, I’ve started recommending ProLon to my patients- more than 100 already. Every patient who completed the 5-day regimen has lost weight and all found the experience very educational, in some cases eye opening. And nearly everyone was able to complete it.

I plan to use ProLon as an essential tool at my disposal to help my patients kick start and adopt a healthier lifestyle.”

“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.”

“As a 20+ year healthcare executive and patient to some of the best providers and care available, Prolon was the single most effective and easy to follow health program I have ever done.  By eating the healthy, clean Prolon products for just 5 days, I have experienced the lasting effect of being 7 pounds lighter, more energy and mental clarity than ever, and most importantly, adopting positive nutritional habits after just one round of Prolon.”

“I tried the ProLon FMD on the encouragement of a friend who was familiar with the company. I had been routinely using intermittent fasting (IF) for weight loss, but wasn’t haven’t much luck shedding a few stubborn pounds. As a scientist, I was curious why a fasting mimicking (FMD) diet was different than IF, and I read the clinical studies on the ProLon website. I was encouraged to read that a FMD diet can not only help a person lose weight but more significantly, the FMD promotes immune system regeneration, stimulates stem cells and reduces risk factors for diabetes and heart disease. I just finished participating in my first ProLon FMD, and I found it much easier to stick with a 5-day fast than I anticipated. The food was really tasty and filling, and the FMD kit came with clear instructions. I had plenty of energy during the FDM, and never felt an urge to veer from the fast and eat extra food. At the end of 5 days, I lost those stubborn 3 pounds! .”

“Following my endocrinologist Dr. Maria Tulpan’s recommendation, I completed the five-day ProLon meal plan six months ago and have maintained my results since. As a result of ProLon, my blood sugar is lower, my elevated cholesterol was reduced to a normal level, I am 12 pounds lighter, I’m sleeping better, and I am on less medication. In fact, my doctor has taken me off of one pill completely! I found myself making better and more mindful choices even after the five days were over. It’s truly unbelievable. Plus, the food was good! I am eager to do it again. I would recommend ProLon to anyone who is serious about getting healthier.”
