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.

Hi Brett,
Thank you so much for sharing your experience with us!
We're delighted to hear that you enjoyed your first 5-day fast and found the experience positive. It’s always wonderful to hear from customers who feel empowered and encouraged to continue incorporating Prolon into their wellness journey.
Many of the clinical studies on the fasting-mimicking diet were conducted using monthly cycles for the first three months, followed by less frequent maintenance cycles depending on individual goals. We're excited to hear that you're considering repeating the program every few months and making it part of your long-term health routine.
Thank you again for your kind words and for being part of the Prolon community. We look forward to supporting you on your future fasting journeys.

I haven’t received anything yet but email after email — you want me to recommend something I haven’t even received? So far this business has a 10/10 for being annoying and over-marketing. Unless that stops I’ll cancel my subscription.

Hi Susan,
Thank you for taking the time to share your feedback. We sincerely apologize for the frustration this experience caused.
To provide some context, Prolon sends an initial review request shortly after an order is placed to gather feedback on the ordering experience, website, shipping process, and customer support. A separate follow-up review is sent after customers have had the opportunity to receive and try the product, so they can share feedback on the program itself.
Our goal is to keep customers informed and supported throughout their journey. However, we completely understand that communication preferences vary. Customers can unsubscribe from marketing emails at any time using the link at the bottom of any email, though doing so may also prevent them from receiving fasting tips, educational resources, coaching updates, and other program-related support.
Our Customer Service Team has reached out directly to learn more about your experience and help address your concerns. We truly value your feedback, as it helps us continue improving the experience for all of our customers.

Good product backed by research
Good product backed by research, excellent daily online support coaching sessions. Soups are not very tasty and can be grainy, some of the flavors not good. Also, the price is high if you plan to follow their suggestion of every 25 days. BUT, it is a great reset and you will feel better if you can get through a few 5 day. The non powder are organic and taste better but are pricey

Hi Albert,
Thank you for your message, and we appreciate you sharing your feedback with us.
The reason you receive an initial review request shortly after placing your order is that it is intended to capture your early experience with the ordering and checkout process itself. This helps us better understand and improve the website experience and service at the point of purchase. Additionally, it is also a way to let you know that our customer service team is here for you and ready to support you if you need anything.
Once you have received and had the opportunity to use the product, you will receive a separate follow-up survey where you can share your experience with the program itself.
We understand your concern, and we appreciate you taking the time to let us know how this feels from your perspective. If you have any additional questions, we’re here to help.

Trust the quality based on the sponsors of this product. My biggest concern recently has been potassium but actually only a moderate source of potassium for those on a low potassium diet due to Chronic Kidney Disease.

Hi Cynthia,
Thank you for sharing your thoughts.
We’re glad to hear you feel confident in the quality of the product.
We also really appreciate you highlighting your perspective regarding potassium and CKD-related dietary considerations.
For individuals with specific medical conditions such as chronic kidney disease or those following medically prescribed dietary restrictions, we always recommend consulting with a healthcare provider to ensure any nutritional program is appropriate for their personal needs.
We are grateful for your trust. Thank you again for taking the time to share your feedback.

feeling tortured for nothing
I felt bloated the entire fast period. And in fact continue to feel bloated now at 4 days post-fast...not as bad as during but much more so than pre-fast! I felt no boost in energy or clarity during or after the fast. My weight is down a whopping 4lb, but my body fat is UP 1% & lean body mass DOWN just 1lb. It feels basically like I tortured myself for nothing!

Hi Abbigail,
Thank you for taking the time to share your experience. We truly value your feedback and are committed to ensuring you have the best possible experience with ProLon.
We wanted to acknowledge that feeling bloated is not a fun symptom to have. Bloating can sometimes occur during a significant dietary shift like Prolon, as it is a plant-based, fiber-rich program that can temporarily affect digestion and the gut microbiome. In most cases, these effects are short-lived and tend to improve once the body fully returns to a regular eating pattern, though individual responses can vary.
We also understand your frustration regarding the results you experienced. Outcomes such as energy, clarity, and changes in weight or body composition can differ from person to person depending on a variety of factors, including baseline metabolism, stress, sleep, and pre- and post-fast nutrition. While many participants report positive benefits, others may not experience the same effects after a single cycle.
Our Customer Service Team has already reached out to you directly via email from customerservice@l-nutra.com to help address and clarify your concerns and work with you toward a resolution.
Your satisfaction is very important to us, and we are dedicated to making your experience as smooth and positive as possible.
We look forward to your response and the opportunity to support you further.
