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 product has produced the results that were promised. Clearer thinking, more energy and we even lost some weight. With the lifestyle change that has occurred, we will certainly lose more. I am glad that our family doctor recommended it.

My Go-To for a Reset
I've done roughly 8 rounds over the past 6 years. It is the only fast I'll do. Easy to follow; but requires your commitment. Nut bars for breakfast, soups for lunch and dinner. Some snacks depending on the day. Sign up for the free coaching zoom calls on the week you plan to do the 5-day; they will walk you through preparing and the day you break the fast. Lots of helpful tips on the calls. If you are registered for that session, they will email you a link if you miss it live. There's 20 years of science behind it and it works. My RDN recommended I give it a try when I hit a plateau after losing the first 30 pounds. I still do this fast when I need a reset. Great customer service. Quick delivery. You can email them with questions. Lots of support. If you do any fast, do this one.

I’ll start by saying
I’ll start by saying, I’ve done the reset twice before this! And obviously liked it as was planning to do the third reset.
I ordered from Prolon.ca directly and paid full price, as I did before. Once box arrived, I was curious as the two different vitamins which were included in previous orders, were not there?!?
I contacted customer service and they said, in very long winded message, they no longer provide! Ok??
I requested a refund as I felt, I ordered kit and parts were missing. After 11 emails back and forth, they asked me to “prove” where on the website, I seen that vitamins were included! By this time their tone was borderline hostile. I however, did take a screenshot of vitamins being included! I asked for the forth time for a full refund! No response and now my emails won’t go through to them. Extremely disappointed as I did like the reset in the past

Hi Tina,
Thank you for taking the time to share your feedback, and we’re truly sorry to hear about your experience with your most recent order.
We understand how disappointing it must have been to notice a difference in the kit compared to your previous resets, especially when you were planning to continue your Prolon journey. We also want to clarify that certain product components have been updated in Canada due to regulatory and formulation changes, which may differ from earlier kits.
Our Customer Service team worked with you over multiple exchanges to review your concerns in detail. A member of our management team also followed up directly to ensure you received additional support and clarification. After reviewing your case, we were able to provide a full refund as a one-time exception, even though this is not our standard policy, in order to ensure a fair and supportive resolution.
We always aim to assist our customers as thoroughly and respectfully as possible, and we’re sorry if that did not come through clearly during your experience. We remain committed to transparency, support, and continuous improvement based on all feedback we receive.
If you would ever like to reconnect, we’re still here to help. You can feel free to contact us via Main Prolon Number +18889265370 or customerservice@l-nutra.com.

That said, we are happy that our team was able to resolve this for you and ensure the subscription has now been properly addressed.
We truly appreciate you bringing this to our attention, and we’re sorry for the inconvenience this has caused due to the change of address.
