Bruce N. Ames, PhD, reveals his 11 longevity vitamins — molecules that activate long-term health enzymes — as part of his Triage Theory of aging. 

Triage Theory is named after the assortment system the French Army used during World War I called Triage, which prioritized the treatment of injured soldiers. 

Model: UM-HET3 mice
Dosage: Astaxanthin was fed at 4,000 ppm in the diet beginning after weaning
Meclizine was fed at 800 ppm in the diet beginning after weaning
Administering fisetin started at 20 months old and was fed continuously or a repeated cycle of three days on and 11 days off at a target of 600 ppm in the diet

Over-the-Counter Wonders: New Research Highlights Two Compounds for a Longer Life
