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.

Reviews on Next Gen

Ready to Eat for the win!

Ready to Eat for the win!

I’ve done prolon 10 times and got to try the new ready to eat! It is a game changer. The soup is fresh and tastes like real food vs powered soup. All of the other elements are the same and are what to expect. Ready to eat soup has made this 10th round enjoyable! I used to drink the soup as a must do and now the soup is something I look forward to like the choco crisp! Nice work on the Ready to Eat!! Will order this every time when it’s available! Convenient and fresh!

Excellent addition to the Prolon range

Excellent addition to the Prolon range

lots of the great things from the previous programs, and the new soups are fantastic! not having to blend the powdered mix with water makes the program so much better.

New soups are a game changer

New soups are a game changer

I’ve loved Prolon for a while now, but their new generation box soups are next-level! The tomato soup tastes like I ordered it from a high-end restaurant — rich, smooth, and so satisfying. The minestrone soup blend is packed with a bold, comforting flavor that feels homemade in the best way. Prolon keeps getting better!

Best Prolon Taste Yet

Best Prolon Taste Yet

I love that this next gen kit is organic but what is really winning me over are the soups. Some (such as tomato) taste about the same, but others (such as the more hearty soups) taste similar but even better. This will for sure be my go to kit going forward.
