A molecule called nitric oxide helps your blood vessels relax, your heart pump better, and your cells make energy properly — when this system goes wrong, it can lead to high blood pressure and heart problems.
Claim Language
Language Strength
definitive
Uses definitive language (causes, prevents, cures)
The claim uses 'regulates' and 'contributing to', which imply direct control and causal involvement rather than mere association or possibility. 'Regulates' suggests active, consistent control, and 'contributing to' implies a direct role in causing the outcomes, making the language definitive rather than probabilistic or associative.

Nitric Oxide Signaling and Sensing in Age-Related Diseases
This study says that nitric oxide helps control blood flow, heart strength, and energy production in cells, and when it doesn’t work right, it can lead to high blood pressure and heart problems—exactly what the claim says.
