Skrivet av företaget
Prolon is a science-driven nutrition brand focused on supporting healthy aging and longevity through evidence-based nutritional programs. Its flagship product, the Prolon 5-Day Diet, is a patented Fasting Mimicking Diet (FMD) developed from more than 25 years of research and 40+ published clinical studies conducted in collaboration with USC, Mayo Clinic, and Stanford, to help the body enter a fasting-like state while still providing carefully formulated nourishment that supports natural cellular renewal. The 5-Day Diet is a complete, pre-packaged nutrition program that includes portioned meals, snacks, and beverages for each day, making the experience simple to follow without calorie counting or meal planning. Clinical research published in peer-reviewed journals, including Nature Communications, found that participants completing three consecutive monthly cycles experienced an average 2.5-year reduction in biological age markers, while also supporting healthy metabolism, preserving lean muscle, and promoting fat loss. But the 5-Day Diet is only the beginning. The same decades of longevity research that gave rise to the FMD also informed Prolon's broader ecosystem of science-backed products designed for everyday life. This includes L-Biome, a precision probiotic formulated to support gut health and metabolic function; fast bars, developed to extend the fasting state between meals; nutrition shakes built around longevity-supporting protein ratios; and guided reset programs that combine multiple Prolon products into structured, longer-term health protocols. Every product in the Prolon line shares the same origin, rigorous peer-reviewed science, and the same goal: to give your body what it needs to function better for longer. Founded on the belief that nutrition should be grounded in rigorous scientific research rather than trends, Prolon develops all of its products using a research-first approach. Prolon is part of L-Nutra, a nutrition technology company dedicated to advancing evidence-based nutrition for healthy aging and longevity. Our mission is to make cutting-edge longevity science accessible to everyone because how you age is not simply something that happens to you. It is something you can actively shape.

Following the 5 day program wasn’t…
Following the 5 day program wasn’t difficult at all. All the meals are prepared for you so there is no guesswork involved. The food was good, and my results were noticeable. Yes, I lost weight and inches, but the best part is I felt great by day 7! I already have cycles 2 and 3 ready and waiting for the succeeding rounds.

We’re so glad to hear that the program felt easy to follow and that having everything pre-prepared helped remove any guesswork for you. It’s also wonderful to hear that you enjoyed the food and noticed meaningful results, not just in weight and inches, but also in how great you felt by Day 7.
It’s especially exciting to hear that you’re already planning your next cycles and feel ready to continue your journey. That consistency is where many people see the most lasting benefits over time.
We’re grateful to be part of your wellness routine and wish you continued success with your upcoming rounds.

I have done water fasts before and felt really miserable. I have done 3-5 day fasts before and could not make go number 2 each time, I felt even more sick. I would get sick from it, headache and throw up. I also cannot eat chocolate for many many years because it gave me an immediate headache that I could not remedy. I have been on the 5 day Prolon fast and I was able to eat the chocolate and got NO symptoms at all. I was not hungry. The food was good and I realize my over eating is not because of hunger but stress and boredom. The team were very attentive when I had questions they responded within the hour. I am very grateful for this experience.

Hard to cancel and a very deceptive
Hard to cancel and a very deceptive, subscription plan. You will likely be signed up for a subscription, make sure to cancel as you will not likely do package again. The fast is not worth the money and could be done on your own. The meals are terrible.

So Far So Good
I had a discovery call with the dietition and that went very well. She was very knowledgeable, kind and helped solve things that would have been a block for me personally.
I later had a couple more questions, so I call the number she gave me, and I left a message. I received an email very shortly after, with a direct line to customer service. I call that number, spoke with the gentleman, he answered all my questions in detail. He also was knowledgeable. He was also kind and patient. Neither person put pressure on me, and were professionally friendly. I think customer service person's name is Manuel.
So I'm off to a great start.
