# LIFESPAN+ Activate - Clinical Longevity Review & Consensus Audit

> **Consensus Verdict**: Formulated with clinically-backed dosages of key longevity compounds including 1g NR for NAD+ elevation, 1.5g TMG for methylation balance, 2g Creatine for cellular bioenergetics, 2g Glycine & 1.5g Taurine for longevity amino acid support, 7g Trehalose for autophagy, and 1g Ca-AKG for epigenetic regulation.

## 1. Executive Summary & Scores
- **Longevity Evidence Score**: **85/100**
- **Evidence Quality Tier**: **silver**
- **Human Clinical Evidence Strength**: 71/100
- **Primary Longevity Classification**: supplements
- **Safety Margin Score**: 92/100 (Higher is safer)
- **Time Burden**: ~15 minutes/day
- **Estimated Monthly Cost**: inexpensive
- **Adherence Friction**: 3/10 (Lower is easier to sustain)
