| How it works | Nitrate → (oral bacteria) → nitrite → nitric oxide via NOS-independent pathway; vasodilation, lower O₂ cost of exercise, lower BP. | Conditionally essential amino acid concentrating in heart and muscle; stabilises membranes, regulates intracellular calcium handling, is an antioxidant, and acts as a weak GABA-A agonist. A 2023 Science study found taurine declines with… |

Its levels fall as you age; topping it up extended healthy lifespan in animals and is cheap and safe in humans. |
| Bottom line | Well-evidenced endurance and BP aid; mind the mouthwash. | Low-risk, promising longevity and endurance support. |
