Företagsinformation
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.

The Real Deal
I had been seeing PROLON Fast while online and finally decided to try it.
I began my first 5 Day Fast on June 3rd... I ate only what was in each days box and followed the program 100% - didn't even have any coffee for the whole 5 days.
I found myself disciplined and not all that hungry (save for maybe Day 3) and never waivered.
After 5 days - I weighed myself on Day 6 and had lost 10 pounds.
I continued eating everything in moderation and using portion control.
I found myself stuck on a plateau and ordered another 5 Day Fast, which I started on July 22nd, so I am currently on Day 5 and down about 5.5 pounds.
Tomorrow I go back to 'normal' eating, but hopefully having reset my body. I hope to continue to lose weight and achieve my goals.

An Easy Option for a 5 day Fast
Not only was the product amazing, but the support was as well. The food (although limited) was delicious and clean. I have been an intermittant faster for years, but could not seem to do any type of meaningful long term fast... Until now with the help of Prolon. I loved the journey so much, I am going to incorporate it into my health coaching program. Kuddos to ProloneLife!

Hi Maria,
Thank you for taking the time to share your feedback. We understand your concern regarding the sodium content, and we'd like to provide a little more context.
Prolon's sodium content ranges between 1.6 and 2 grams per day, which falls within the American Heart Association's recommended daily sodium intake for a heart-healthy diet. During the fasting-mimicking program, sodium plays an important role in helping your body retain the water you drink, supporting hydration and helping offset the electrolyte losses that can occur during fasting. Together with potassium, sodium is essential for maintaining proper fluid balance throughout the program.
We truly appreciate your feedback and understand that everyone's dietary preferences and needs are different. Thank you again for sharing your experience with us.

Feel Like Superman
I came into this with an open mind, hoping to feel a little less bloated. Not only did the bloating go away, but I also feel way more energized, I'm in a better mood, and I'm much more focused, which is something I really need in my line of work.
I'm actually quite shocked by how good I feel. Days 1 and 2 were hard, Day 3 was better, but by Day 4, I felt like Superman.

Svar från Prolonlife
Hi Jordan,
Thank you so much for sharing your experience! We're excited to hear that not only did your bloating improve, but you also experienced increased energy, better focus, and an improved mood. We especially loved your "felt like Superman" description. It perfectly captures what many people notice as they progress through the program!
It's completely normal for the first couple of days to be the most challenging as your body transitions into the fasting-mimicking state. Hearing that Day 4 was such a turning point for you is incredibly exciting.
Congratulations on completing your first round, and thank you for trusting Prolon to be part of your longevity journey. We can't wait to hear how your future rounds go!

Very good products, clear instructions and explanation of the science behind the FMD, superb coaching and text support on Whatsapp. I did not receive the expected welcome package, but as soon as I emailed support to ask about it, it was on its way. Timely answers to questions on the live coaching Zooms and Whatsapp group. Very good experience.

Good program but dislike the soups.
I like the program but really dislike the soups. All flavors are not tolerable for me. Wish there was an alternative to soup

Svar från Prolonlife
Hi Melissa,
Thank you so much for sharing your honest feedback. We completely understand that the soups aren't everyone's favorite, and we truly appreciate you taking the time to let us know. Taste is very personal, and we recognize that everyone's preferences are different.
The soups and every item included in the Prolon program were carefully formulated over more than 20 years of research with a specific purpose: to nourish the body while helping it enter the fasting-mimicking state and access the science-backed benefits of the program, including cellular renewal (autophagy), metabolic support, and healthy aging. For that reason, every ingredient and macronutrient profile is intentionally designed to support the fasting response demonstrated in the clinical trials.
That said, we completely understand that enjoying the food is an important part of the experience. Feedback like yours is incredibly valuable, and we'll be sure to share it with our Product Development team as they continue working to improve the program while maintaining the same clinically studied benefits.
Thank you again for giving Prolon a try and for helping us continue to improve. We truly appreciate your feedback and hope you continue to experience the many health benefits the program was designed to deliver.
Coaching Sessions are a Must.
It was great not having to think about what to eat, best of all, avoiding the temptation to go back to old habits for 5 days. Joining the coaching sessions make all the difference, that daily nudge, especially during the last few days kept me going.
Pea protein-based soups were not my favorite, so I chopped up my olives (another non-favorite) and put them into the soup along with any cracker crumbs from the packet. Tomato soup is my hands down favorite!

Hi Annette,
Thank you so much for sharing your experience!
We're so happy to hear that the structured meal plan and daily coaching sessions helped you stay on track and avoid slipping back into old habits. Having that extra encouragement, especially during the final days, can truly make a difference, and we're glad it was such a valuable part of your experience.
We also love hearing how you've found ways to enjoy the meals even more! Chopping the olives into the soup and adding the cracker crumbs is such a creative idea, and we're happy to hear the Tomato Soup earned the title of your favorite.
Congratulations on completing your program and thank you for allowing us to be part of your health journey!
