# Blood Donation (Phlebotomy) - Clinical Longevity Review & Consensus Audit

> **Consensus Verdict**: Reduce your body's oxidative load by donating blood, which can improve metabolic function and cellular energy today while supporting long-term cardiovascular health.

## 1. Executive Summary & Scores
- **Longevity Evidence Score**: **86/100**
- **Evidence Quality Tier**: **silver**
- **Human Clinical Evidence Strength**: 71/100
- **Primary Longevity Classification**: other
- **Safety Margin Score**: 92/100 (Higher is safer)
- **Time Burden**: ~15 minutes/day
- **Estimated Monthly Cost**: inexpensive
- **Adherence Friction**: 7/10 (Lower is easier to sustain)

## 2. Biological Mechanisms of Action
Mechanically removes excess serum ferritin (iron) and microplastics from circulation, reducing systemic oxidative stress and lipid peroxidation.

## 3. Canonical Longevity Vector Impacts (The 8 Longevity Pillars)
- **Heart Health & Endothelial Function**: **87/100** [Rank #16 of 133 in Heart] - Effect: Lowers blood viscosity, prevents iron-catalyzed hydroxyl radical generation in vascular walls
    - Mechanism: Reduces excessive iron stores, preventing Fenton reaction-mediated hydroxyl free radical attacks on endothelial lipid membranes.
- **Cellular Longevity & Autophagy**: **91/100** [Rank #26 of 131 in Cellular] - Effect: Up to 30% reduction in persistent bioaccumulated perfluoroalkyl substances (PFAS)
    - Mechanism: PFAS compounds bind tightly to serum albumin; regular blood/plasma removal forces hepatic de novo synthesis of pristine albumin, clearing recalcitrant forever chemicals.
