Hypertension Clinical Trial
Official title:
Effects of S-allylcysteine-rich Garlic Extract and Dietary Inorganic Nitrate Formula (Vascanox® HP) on Blood Pressure and Nitric Oxide Levels: an Open-label Clinical Trial Among Hypertensive Adults
Conversion of dietary nitrates to nitric oxide (NO) is a non-canonical pathway that plays an important role in NO biology, particulalry under pathological conditions. Nitrate supplementation has been shown to help control mild hypertension. Recent studies have suggested that another gaseous transmitter, hydrogen sulfide, also influences NO biosynthesis and metabolism. This open-label clinical trial will evalute the effect of Vascanox® HP, a proprietary formulation that combines dietary sources of nitric oxide and hydrogen sulfide, on nitric oxide bioavailability and on blood pressure in subjects experiencing elevated blood pressure. Participants will supplement with Vascanox® HP for four weeks. Blood pressure will be measured at baseline, two weeks, and fours weeks. Salivary nitric oxide will be assessed prior to and two, six, and 24 hours after dosing on the first day of the study and prior to and two hours after dosing at subsequent study visits. Participants will also self-monitor their saliva nitric oxide levels and blood pressure daily for 4 weeks. Changes in study outcomes over time will be evaluated via analysis of variance (ANOVA) and paired t-tests.
