Dead Mitochondria Might Be Fueling Cardiovascular Aging — Here’s The Fix

This is a really exciting conversation with Dr. Davide D’Amico from Timeline, where we’re taking a closer look at Urolithin A and heart health. It should come as no surprise that this mitochondrial wonderkin of a nutrient is showing promise here—especially when you consider that 40% of the heart’s weight is mitochondria. That’s an extraordinary factoid, and one that really shifts how we think about aging in the cardiovascular system.

What’s particularly compelling in this new preclinical research is that restoring mitochondrial function may do more than just improve ejection fraction. It may also have ripple effects on other hallmarks of aging—like chronic inflammation, cellular stress signaling, and impaired autophagy. I’m thrilled Timeline is continuing to invest in both preclinical and clinical research on this front—and yes, I’m totally nerding out over what they’re up to. ~DrK
