The Claim
Spermidine is essential for the induction of autophagy and mediates the longevity benefits of caloric restriction.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Spermidine is required for autophagy to occur and is necessary for the extension of lifespan caused by reduced calorie intake.
See the scientific wording
Spermidine is essential for the induction of autophagy and mediates the longevity benefits of caloric restriction.
When food intake drops, the body makes more spermidine, which activates a protein called eIF5A by adding a special chemical group to it. This activated protein then tells the cell to start cleaning up damaged parts by breaking them down and recycling them. This cleanup process keeps cells healthy, prevents aging damage, and allows the organism to live longer.
What the research says
1 studyStudy: Spermidine is essential for fasting-mediated autophagy and longevity
When you eat less, your body makes more of a substance called spermidine, which helps clean out damaged cells — this cleaning is key to living longer. If you block spermidine, fasting doesn’t help you live longer or stay healthier anymore.
