Escrito pela empresa

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.

I love the Prolon FMD programs

I love the Prolon FMD programs, products, and customer service! All three are stellar and I have no doubt Prolon is helping me achieve the best health possible. Getting the benefits of fasting while eating their extensively researched programs is a win-win!

Recommended by my best friend.

The zoom calls with Cynthia Sass were very helpful, offered great tips, and made following the plan easy. It helped me keep focus daily on why I was doing this and gave me the motivation to continue. My best friend and I did the program together after her recommendation and it was helpful to have someone to lean on and laugh with through the process. I never thought I would look forward to eating green olives so much! We are going to try the 3 months consecutive and hope to continue making this apart of my lifestyle. I am grateful that she cared enough to recommend this product and that we could share this experience together.

Don't overthink it

Don't overthink it, just order it and get started. I contemplated fast-mimicking diets, and even attempted on my own. Prolon gives you clear guidelines and an easy to follow program.

Excellent support for FMD

The Prolon team guides you through the five day fast-mimicking diet via free webinars, social media, and detailed instructions in the box. I felt very supported and knew how to navigate doing a fast for the first time (3years ago) in my life. It helped me understand my relationship with food. I learned about autophagy and cellular rejuvenation, and the connection to longevity and a healthy lifestyle.

This company is top notch

This company is top notch. Everything from their products, to the research that backs them. Their support through the fasting experience, as well as additional product solutions outside of your main fasting periods. I'm so grateful for the solutions they offer to make the clinically backed "Fasting Mimicking Diet" so approachable and available for people to self administer this fast.

Easy reset that makes you feel great after

The reset is relatively easy to do and makes you feel less bloated, mentally and physically lighter, and curbs cravings. Day 3 was the most challenging for me, but overall the experience was positive. I lost 5-6 pounds.

You send way too many emails

You send way too many emails. If I'm not 100% certain that your stuff works, I will never buy from you again. I'm sure you are following some guidance around how to message people after a purchase, but it is way too much, too annoying. If would limit it to one per week, that would be fine.

Prolon is a lifestyle change

This is the 2nd time my husband and I have done Prolon. It is quickly becoming a lifestyle change. Prolon makes us feel better resulting in blood work numbers being much better. It is a good reset. We plan continuing on with the program 3 to 4 times a year. (We used to do 21 day cleanses and Prolon is much easier with only 5 days.)
