Cells have an extraordinary ability to adapt to stress through hormesis, where low levels of stress induce protective responses. This concept extends to mitohormesis, where mitochondrial stress signals promote longevity. In this third article in our series of mini articles exploring aging pathways, we delve into these mechanisms and their role in lifespan extension, focusing on the impact of exercise, diet, and specific nutraceuticals.

Cellular Stress Response Mechanisms
Hormesis involves activating protective genes and producing heat shock proteins in response to stressors like oxidative stress. At the mitochondrial level, mitohormesis triggers responses that include creating new mitochondria and producing mitochondrial heat shock proteins. Molecules like ATF4 and FGF21 are crucial in this adaptive process, with FGF21 levels elevated by exercise and protein-restricted diets, contributing to lifespan extension.
The Role of FGF21 in Longevity
FGF21, a key player in mitohormesis, is a hormone that drives systemic stress responses and promotes longevity. Elevated by exercise and specific diets, FGF21 has been shown to extend the lifespan of mice significantly. Nutraceuticals like glucosamine and pterostilbene, found in NOVOS Core, also act through hormesis, enhancing cellular stress responses and promoting healthy aging.
Unlocking the Power of Hormesis
Harnessing the benefits of hormesis and mitohormesis can significantly improve health span and longevity. Understanding these adaptive mechanisms and incorporating strategies like exercise and targeted nutraceuticals can enhance our resilience to stress and promote a longer, healthier life.
