Polyamines, molecules that help keep our cells healthy as we age, have been getting lots of attention in longevity circles. But researchers just found they might be a double-edged sword. While they help with cellular cleanup, high levels of these same molecules show up in aggressive cancers. It's a classic case of 'the dose makes the poison' – and it might be time to rethink how we use these supplements.

Key Findings
- Polyamines help with cellular cleanup and healthy aging
- High polyamine levels are consistently found in aggressive cancers
- The same properties that make polyamines good for longevity might also support cancer growth
Practical Takeaways
- Consider getting polyamines from food sources rather than supplements for now
- If you're taking polyamine supplements, discuss with your doctor, especially if you have a family history of cancer
Limitations & Caveats
- Most research done in laboratory settings, not long-term human studies
- Unclear if supplement doses would have same effects as naturally occurring levels
- More research needed to understand optimal dosing
