New study shows three monthly cycles of ProLon® may reduce biological age by 2.5 years

Chronological age is just a number. What really matters is your biological age — a measure of how your cells and body are actually ageing. This is becoming the gold standard in longevity science. And now, a breakthrough 5-day precision nutrition program called ProLon® is showing promising results in reversing biological age.

Developed by the longevity company L-Nutra, ProLon® is the world’s first and only patented Fasting Mimicking Diet (FMD). This plant-based, 5-day program delivers all the benefits of fasting — without having to stop eating altogether. Clinically tested in over 32 trials worldwide, ProLon® is designed to activate the body’s natural rejuvenation processes and promote long-term health.

Breakthrough Study Highlights

A recent study published in Nature Communications found that three monthly cycles of ProLon® reduced participants’ biological age by an average of 2.5 years. This was measured using a validated phenotypic bio-age score developed by researchers at Yale University and the University of Southern California (USC).

Importantly, participants maintained muscle mass and did not need to rely on supplements or extreme fasting protocols to achieve these results — highlighting ProLon®’s unique ability to support healthy aging in a safe, sustainable way.

Andrea Ghirardi, CEO of L-Nutra Europe, explains:

“We created ProLon® to give people an accessible, scientifically rigorous way to influence their aging process from the inside out. ProLon® is intended for healthy individuals who want to improve their healthspan and reduce their biological age through periodic fasting.”

For those with chronic health conditions, L-Nutra also offers a specialized clinical pathway through L-Nutra Health, a medical division focused on practitioner-guided fasting-mimicking protocols tailored to conditions like type 2 diabetes.
