Italian Citrus Bergamot + Nitric Oxide Boost is a complete cardiovascular formula that features BergAmore™, the patented, clinically studied polyphenol blend of authentic bergamot from Calabria, Italy, with S7® botanical nitric oxide booster. These powerful ingredients work in harmony to support healthy cholesterol, nitric oxide production, and blood flow.
What is S7®?
What is S7®?
S7® is a patented, all-natural blend of superfoods (green coffee bean, green tea, turmeric, tart cherry, blueberry, broccoli and kale) clinically shown to boost and sustain nitric oxide levels. Studies show a 230% increase after the first dose and sustained 52% higher levels of nitric oxide after 90 days. This means better blood flow, which leads to more energy and stamina and healthier circulation. It contains zero caffeine, stimulants or nitrates. Compared to beet juice, which is traditionally used to increase nitric oxide levels, our antioxidant blend is 10x more potent.
