The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
The best documented lifespan extension due to spermidine was in fruit flies, which increased 30% In worms & yeast, extension was around 15–25% In mice, there is up to 25% extension of mean lifespan, with lifelong administration
