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.

Taking a chance and investing in your health
I've done a few water fast before and let me tell you it was extremely hard to get through rewarding yes but hard to get through but the way they lay it out on their Advanced system and the fact that you get to do it for 5 days I even start eating food and liking things that I never liked it like it just woke up my palate so I'm grateful thankful to them and I'm looking to hopefully get some more money to invest in my health and I'd like to get on a regimen where I would do multiple rounds of these every year if not multiples month after month after month thank you guys you really made an impact on my life

Hi Ronnie,
Thank you so much for taking the time to share your experience.
We're truly honored to hear that Prolon has had such a meaningful impact on your health journey.
It's wonderful to hear that, compared with your previous water fasts, you found the Prolon program to be a more manageable experience while still feeling rewarding. We also love hearing that it helped you discover new foods and appreciate flavors you hadn't enjoyed before, that's a fantastic outcome!
We're grateful to be part of your wellness journey and are excited to hear you're considering incorporating Prolon into your long-term routine. Many people choose to complete the program monthly, quarterly, or biannually depending on their individual health goals, and we always encourage discussing the best approach with your healthcare provider.
Thank you again for your kind words and for trusting Prolon. We wish you continued success on your longevity journey and look forward to supporting you along the way!

I wanted to let the company know that I enjoyed the product. Unfortunately, soon after I got the second batch of products I ended up needing open-heart surgery. Unfortunately, I could not receive the next shipment because the doctor has me on a special diet. So when I saw that my subscription was ready I wrote in and had great emails conversation with Manella. She was so professional and kind and understanding and I really need that right now. When I feel better and I get the doctors OK I'll reach out again. My functional nutritionist recommended this for me. Thank you for the product and thank you for having Manella on your team.

Hi Kathy,
Hi there,
Thank you so much for taking the time to share this with us, and I’m truly sorry to hear about everything you’ve been going through. I hope your recovery from open-heart surgery is going as smoothly as possible.
I’m really glad to hear that you enjoyed the product and that Manuela was able to support you with kindness and care during such a difficult time. I will make sure your kind words are shared with her and the rest of our team, it will mean a lot to her.
Of course, we completely understand your need to pause your subscription while you focus on your health and follow your doctor’s guidance. Your account will remain on hold, and there’s nothing further you need to do right now.
When you’re feeling better and your doctor gives you the green light, we’ll be more than happy to support you again whenever you’re ready.
Wishing you strength and a smooth recovery ahead, and thank you again for your thoughtful message.

This is my second time doing the Fasting Mimicking Diet and both times have been a great experience. Each day's food is in a separate box with suggestions on how to divide up each meal, but also lets you choose what and when to eat out of each days box. Signing up for the health coaching is a great help to educate and motivate you each day. When you have an issue, there response time and help is 2nd to none. The help transitioning back to a regular diet with some recipes is very helpful.

Site is difficult to navigate
Site is difficult to navigate. It is frustrating when ordering one kit, the algorithm puts the request in as an auto renewal.

Svar från Prolonlife
Hi Deborah,
Thank you for taking the time to share your feedback with us, and I’m sorry for the frustration you experienced while navigating the site and placing your order. I understand how confusing it can be when an order defaults to an autorenewal setting when that’s not what you intended.
I also want to gently clarify that the website does clearly outline the difference between a one-time purchase and a subscription before checkout, and the selection is made at the time of ordering. However, we absolutely understand that this can still be missed or feel unclear in the moment, and we’re always working on making that distinction even more visible and user-friendly.
If your subscription was selected by accident, please don’t worry. We’re happy to help review your order and make any adjustments needed. You can contact us anytime at customerservice@l-nutra.com, and our team will take care of you directly.
Thank you again for your feedback and for sharing your experience with us, it genuinely helps us improve.

I also appreciate you bringing the coaching session confirmations to our attention. I’m sorry for the inconsistency you experienced after your first round and for the inconvenience of having to follow up to request the link. I understand how important it is to have those details shared clearly and in a timely way, especially when you’re actively participating in the program.
We’ll make sure this feedback is shared with our team so we can improve the consistency of our coaching communications moving forward.
We truly appreciate your engagement and your commitment over multiple cycles. If there’s ever anything you need or if a session link is missing again, please don’t hesitate to reach out. We’re always here to support you.
