Prolon, essential to vibrant life!

Everyday we stress and intoxicate our body and mind with our current lifestyle, nutrition, environment we live under. As we age, our cellular capability to detox, recover and heal decrease and older senescent cells outnumber young vibrant cells.

Our ancestors had a natural secret to defend against accelerated aging and to rejuvenate younger cells: proLonged fasting (> 3 days). When fasting, the body uses its reserves (fat and glycogen) for the first 2 days (Intermittent Fasting period) but when fasting crosses 3 days or more (the prolonged fasting period), the body undergoes a next level of ‘protective and rejuvenative defense called autophagy.

In modern days, we accelerate cellular damage and aging vs going into periods of autophagy, recovery and rejuvenation.In 5 short days ProLon allows your body to go into a rejuvenating state, while consuming macro and micro nutrients to keep your body nourished.

Backed by & continually advancing through science.

After two decades and tens of millions in Research & Development, L-Nutra (a leading Nutri-tech company) and The University of Southern California, led by Dr. Valter Longo were able to identify cellular radars that detect nutrition, called Nutrient Sensing Pathways, and to develop a 5 day Nutrition Program that nourishes the body while the food sensing pathways are not triggered and therefore providing the prolonged fasting benefits.

Prolon provides the body with healthy, plant-based ingredients that have been scientifically demonstrated to provide the body with optimal nourishment while not activating the key pro-aging pathways, or food sensing pathways — pathways which are activated by normal diets.

    My Prolon Fast

    This is my fourth Prolon fast and I absolutely love it! I always feel rejuvenated afterwards; I have more energy and clarity. And you don't feel like you're starving yourself. Thank you Prolon for creating this FMD program!

    Life Changing!

    Such a great and healthy box! I chose to try this as a close friend recommended it, and we fasted at the same time. For me it was a cleanse, and fresh start into healthy living! By day 3, it was hard, and day 5 was even harder but it’s mind over matter! I’d highly recommend and I will return to do it again and again!

    Well worth trying

    My wife and I did the Prolon five day fast. We made it through and lost real weight. In fact, we really didn’t feel like eating afterward! We couldn’t return to our prior diet, as expected. We have continued to be 700-1,100 calories a day lower than before the diet, simply because our desire to eat more is gone.

    This apparently happens to some, I have found out. In essence, we have to make ourselves eat more than we want to, now.

    We will be doing a second round in a couple weeks. This diet seems to reset something inside we needed reset.

    Here’s hoping good health just keeps coming at us—and you!

    Give it a try!

    I didn't think I could do it, but they make it really doable. I'm going to try the 3 rounds to get full benefits. You should try it.
