Key Takeaways

  • GDF15 is a molecule strongly associated with aging, chronic diseases, mortality, disability, and cognitive decline.
  • It’s unclear whether GDF15 directly causes these issues or if it’s a marker of stress in the body.
  • Avoid intervening on GDF15 levels until its role is better understood.

Notable Quotes

“We still don’t know whether GDF15 is causal or if it’s a thermometer of our body to react in a condition that is under stress.”

Bottom Line

Focus on maintaining overall health and managing stress, but avoid targeting GDF15 directly until more research clarifies its role.
