Inorganic nitrate supplementation (316-860 mg/day) improves vascular function and lowers blood pressure in older adults, which may indirectly support skeletal muscle health by enhancing nutrient delivery.

Older adults can improve blood pressure and vascular health by consuming inorganic nitrate (e.g., from beetroot juice) at doses of 316-860 mg per day. This may help deliver more nutrients to muscles, though direct muscle-building effects are not yet fully proven.

NO3 ingestion between 316 and 860 mg/day resulted in a decrease in systolic and diastolic blood pressure by 3.55 and 1.32 mmHg, respectively [57].
