## Media Hype vs. Absolute Clinical Reality (Information Gain Audit)

- **Viral Headline Claim:**
- **True Placebo-Adjusted Absolute Outcome:** Taurine supplementation extended median lifespan in mice by 10-12% and improved bone density, glucose tolerance, and gut barrier integrity in primates. Human serum taurine drops ~80% between ages 20 and 60.
- **Relative vs. Absolute Statistical Breakdown:** The 10-12% lifespan extension occurred in rodents dosed at 1,000 mg/kg daily. Using the FDA body surface area allometric conversion factor (divide animal dose by 12.3), the Human Equivalent Dose (HED) is 81.3 mg/kg daily—equating to 3.0g to 6.5g/day for adults weighing 60kg to 80kg.
- **Funding & Sponsor Audit:** National Institutes of Health (NIH), European Research Council, and institutional academic grants (Independent Academic / NIH)
- **Human Equivalent Dosing Protocol:** Human equivalent allometric dose is 81.3 mg/kg daily, split into 2 divided doses with morning and evening meals.
