Nitrates are crucial for the maintenance of homeostasis. Previous studies have indicated potential adverse effects on the organism; however, Songlin Wang’s group discovered that exogenous nitrate supplementation can prevent and control oral and systemic diseases [1]. Additionally, it plays a role in regulating various functions, including vascular tone, antioxidant activity, inhibition of inflammatory factor release, glucose metabolism regulation, and prevention of ischemia-reperfusion injury [2]. Neurological disease protection is an important part of the homeostatic regulation by nitrates.
