Executive Summary

Your panel converges tightly on training, sleep and protein sufficiency. Supplement claims split the room, with strong support only where a deficiency is being corrected — creatine being the notable exception.

02

What Everyone Is Talking About

The themes your panel returned to most across 147 supported sources.

  • Sleep regularity outperforms sleep duration alone
  • Creatine monohydrate has consistent strength and cognition effects
  • Role of most longevity supplements
  • Resistance training is the highest-leverage longevity intervention
03

Strongest Areas of Agreement

  • Resistance training is the highest-leverage longevity intervention
  • Sleep regularity outperforms sleep duration alone
  • Creatine monohydrate has consistent strength and cognition effects
04

Biggest Disagreements

Disagreement is preserved, never averaged away.

  • Optimal protein intake above 1.6g/kg
  • Value of continuous glucose monitoring in healthy adults
  • Role of most longevity supplements
05
