Experimental: Vascanox® HP |
Dietary Supplement: Vascanox® HP
Vascanox® HP is a proprietary formulation that combines dietary sources of nitric oxide and hydrogen sulfide aimed at increasing the levels and duration of nitric oxide biosynthesis. Vascanox® HP contains an advanced blend of berry extracts in addition to beet root powder, black garlic, vitamin C, and minerals known to influence nitric oxide biosynthesis and metabolism. Because of the particular combination of ingredients, Vascanox® HP is expected to affect both canonical and non-canonical pathways of nitric oxide production and to augment nitric oxide reservoir in the body leading to an increased and prolonged nitric oxide bioavailability. |
- Blood pressure [ Time Frame: Assessed at baseline, at 2 weeks, and at the 4 week conclusion of study ]Change in blood pressure in millimeters of mercury (mmHg) assessed in the branchial artery
- Salivary nitric oxide [ Time Frame: Salivary nitric oxide assessed prior to and two hours after dosing at baseline, 2 weeks, and at the 4 week conclusion of the study. Salivary nitric oxide will be additionally assessed at 6 and 24 hours after dosing on the first day of the study only. ]Salivary levels of nitric oxide assessed using commercially available FDA registered strips. Nitric oxide test strips measure nitrite, which is used as an established surrogate marker for nitric oxide.
