Study Overview
Brief Summary
This study will investigate the effect of a nitric oxide supplementation product, Neo40 Daily®, on blood pressure in pre-hypertensive and mildly hypertensive adults. Subjects will take 2 lozenges per day 12 hours apart for 8 weeks. Half of the subjects will receive Neo40 Daily® and the other half of the subjects will receive placebo.
