Biohacker and entrepreneur Dave Asprey says upgrading mitochondrial health is key to building physical resilience and extending lifespan. In a blog post on his website, Asprey outlines how improving mitochondrial function can “slow aging, boost energy, and support nearly every system in your body.”

“Mitochondria are the power plants of your cells,” Asprey wrote in the post. “When they work well, you have more energy, better focus, and a stronger immune system. When they don’t, you age faster and feel weaker.”

Asprey recommends supporting mitochondria through a combination of cold exposure, exercise, red light therapy, polyphenol-rich foods, and supplements like CoQ10 and PQQ. He also stresses the importance of quality sleep and stress reduction to protect mitochondrial function.

Mitochondria play a central role in producing ATP, the molecule that powers cellular processes. Research has linked mitochondrial dysfunction to a range of age-related diseases, including Alzheimer’s, cardiovascular disease, and type 2 diabetes.

Dave Asprey is the founder of Bulletproof and a leading figure in the biohacking community. He has authored several books on health and longevity and frequently shares protocols for optimizing human performance.
