Skrevet af virksomheden
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.

Prolon took the guess work out

Hi Beverly,
Thank you for taking the time to share your experience. We’re so glad to hear that the program helped take the guesswork out and that you found it easy to follow overall.
Days 4 and 5 can definitely be the most challenging for some people as the body fully settles into the fasting-mimicking state, so it’s great to hear that you pushed through and were able to experience the benefits of completing the program.
We truly appreciate you being part of the Prolon community, and we’re here anytime if you have questions or need support for your next cycle.

A very satisfied new customer!
I'm on day 3 and am finding the program to be easier to follow than imagined. I do have a good framework around food intake, and my body does not need a lot, which is why I took on the program to begin with. The soups are good and the tea, crackers, olives, bars and chocolate "goodie" are satisfying. I'm really never hungry. I took the coaching advice and stayed busy this week, cancelled all outings, am in bed early, and am focused on me! I just signed up for a subscription and will attempt to follow the program 1x/month for the next few months.

Too much advertising
I don't like that when I'm purchasing something that you're advertising constantly literally every other day it's your last day Sunday is your last day and then Monday today's your last day I think that's ridiculous advertising and I don't like that you charge shipping and I don't like that when you purchase it it has a space for a gift code or a discount code but you don't offer a code so why bother putting that there. And I think anybody that is subscribed should get a lesser price than somebody who is not. I haven't received the product and I think it's ridiculous that you sent an email out as soon as you buy something asking how you did. You didn't do great it takes 7 to 10 days to get it. You should wait two weeks before you send out a review the ad advertising and the surveys are constant and annoying.

I've completed 9 rounds, anyone notice Prolon changed a few months back?
I've completed 9 rounds, and somewhere around the 5th round they changed the packaging and taste of the crackers, they are HORRIBLE!! Also, the flavor of the olives is not the same standard as before. I used to love Prolon, now I just "like" it, but I'm committed to one full year of monthly 5 FMD. 2 more rounds and I'll choose another company unless they start allowing choice in the soup, fasting bars, and L-drink flavors. They think offering different boxes is enough, but it is not. I also dislike the giant packaging boxes. I have completed many rounds and feel it's easier and cheaper along with being environmentally conscious to decrease the packaging waste!!

Hi Laurel,
Thank you for sharing your experience and for your continued commitment to the program. Completing nine rounds is an incredible level of dedication, and we truly appreciate you being part of the Prolon community for so long.
We’re sorry to hear that the recent changes to the crackers and olives did not meet the expectations you had based on your previous experiences. Your feedback about taste, as well as your thoughts on having more flexibility in choosing soups, fasting bars, and L-Drink flavors, is very valuable. We understand how important these details become for customers who complete multiple cycles, and we will be sure to share your comments with our product and development teams.
We also appreciate you bringing up your concerns about the packaging and environmental impact. Feedback like this helps inform ongoing improvements as we continue working to balance product protection, quality, and sustainability.

Hi Lorena,
Thank you for taking the time to share your experience with us. It’s wonderful to hear that you’re enjoying the taste of the foods and that you’ve found the program both satisfying and supportive for your health goals.
The meals in the Prolon program are carefully designed to provide nourishment while supporting the fasting-mimicking process studied in clinical research, which is why many people are pleasantly surprised by how filling and enjoyable the foods can be throughout the five days.
We’re truly grateful for your feedback and for having you as part of the Prolon community. If you continue your journey with future cycles, we’ll be here to support you every step of the way.

Hi Betty,
Thank you so much for taking the time to share your experience. It’s truly wonderful to hear how much energy you’re feeling and how the program has helped you build a new relationship with food.
Many people notice similar shifts after completing their FMD cycles, especially when following the protocol as it was studied in the clinical trials, completing three consecutive monthly cycles and then reassessing how they feel. It’s great to hear that you’re already looking forward to your third cycle next month.
Most of all, it means a lot to us to know that ProLon has had such a positive impact on your life. Our goal is always to support people in feeling empowered, informed, and confident in their health journey, and feedback like yours reminds us why we do this work.
We’re so grateful to have you as part of the Prolon community, and we’ll be cheering you on during your next cycle.

Somehow
Somehow, a different account was created for me under my husband's email (who does not order proton). I didn't;t realize I had created a subscription because when I go to my account it does not show the last two orders. I only knew I was getting an order because my credit card was charged. I cannot modify my account or merge the two accounts for accuracy.

I love the products, but the emails are not carefully worded. I kept getting emails saying to expect my delivery of Prolon foods today. What it actually meant was, that my order was being processed today. So I had to pay extra for expedited shipping. When you get fired up to start a fast, you want it to be on time 🙂
