Japan’s parsley-powered bet on aging among XPRIZE finalists
Can a common vegetable really delay aging at the cellular level?
A Tokyo-based startup named TIME TRAVELER has entered the global race to extend healthy human lifespan by focusing on a humble kitchen herb. The company, part of the XPRIZE Healthspan competition’s Milestone 2 Awardees, believes parsley contains compounds that could slow cellular aging. Their approach is one of ten finalists sharing a $101 million prize pool aimed at breakthroughs in longevity science.

Blood Clots and Brain Tumors Linked by Overactive PlateletsThe startup’s hypothesis centers on apigenin, a flavonoid abundant in parsley, which preliminary studies suggest may reduce inflammation and oxidative stress linked to aging. TIME TRAVELER is developing a standardized extract for clinical testing, aiming to validate its effects on biomarkers of biological age. Unlike synthetic drugs, their strategy leverages a food-derived ingredient with a long history of safe consumption, potentially lowering regulatory hurdles.
What if the next antiaging breakthrough is already in your fridge?
The company cites early laboratory data showing their parsley-derived formulation activates pathways associated with autophagy and mitochondrial repair—key mechanisms in cellular renewal. While human trials are still pending, they argue that dietary compounds like apigenin offer a safer, more accessible route to healthspan extension than pharmaceutical interventions. Critics note that translating lab results to real-world aging effects remains a significant challenge, but TIME TRAVELER insists their food-first approach could democratize longevity science.
If successful, TIME TRAVELER’s model could shift focus from expensive, high-tech solutions to everyday nutrition as a foundation for aging well. Their work underscores a growing trend in longevity research: looking beyond labs to traditional diets and overlooked plants for answers. As the XPRIZE Healthspan competition advances, this Tokyo team’s parsley-powered bet may prove that the most potent antiaging tools are not always the most complex.
What makes parsley special in antiaging research? Parsley contains high levels of apigenin, a natural compound studied for its ability to reduce cellular damage and support metabolic health, which are key factors in aging processes.
Frequently Asked Questions
How does TIME TRAVELER plan to test their parsley-based approach? They are developing a purified extract for clinical trials that will measure changes in biological age markers, such as epigenetic clocks and inflammation indicators, over a defined period.
Why focus on a food ingredient instead of a synthetic drug? Using a food-derived compound like apigenin may offer better safety profiles, broader public acceptance, and faster pathways to real-world application compared to novel pharmaceuticals.
