Spermidine-focused piece examining whether dietary sources or supplements better support autophagy and broader longevity research, with guidance for curious readers.
Key Takeaways
- Spermidine extended median lifespan by up to about 25% in multiple animal models including mice, flies, and worms.
- A 20-year observational cohort found people with highest dietary spermidine intake had roughly 30% lower all-cause mortality.
- Randomized clinical trial evidence for spermidine supplements is limited and mostly disappointing compared with observational and animal data.
