Nicotinamide Mononucleotide in Hypertensive Patients

Study Overview
=================
Brief Summary
-----------------
Cardiovascular and cerebrovascular diseases are most terrible killers endangering the health of Chinese residents, and hypertension is the most important risk factor. Hypertension related vascular function and structural damage are the common pathological basis and initiation of cardiovascular and cerebrovascular disease. Therefore, reducing blood pressure and delaying or reversing vascular injury is an effective way to treat hypertension and prevent cardiovascular disease. NAD+ (nicotinamide adenine dinucleotide) is a coenzyme of many kinds of dehydrogenases in the body, and is an essential molecule in the basic process of life support. The latest research found that with the growth of age, the level of NAD+ is decreasing, and increasing the content of NAD+ can prolong the life of multiple species including human. NMN (β - nicotinamide mononucleotide) is a natural NAD+ precursor in cells. Recent clinical trials found that NMN supplementation can effectively improve the level of NAD+ in cells, delay aging, improve the metabolic process of cells without adverse reactions. However, the effect of NMN supplementation on reducing blood pressure and protecting vascular endothelial function has not been reported. Therefore, this study aims to focus on hypertension, a major chronic disease, and to observe the effects of NMN supplementation on vascular function and blood pressure in patients with hypertension, so as to provide a new treatment strategy for hypertension and associated vascular injury.
