Effects of a Brown Seaweed Tart Cherry Blend in Mild-moderate Hypertension

The brown seaweed species Ascophyllum nodosum is rich in bioactive polysaccharides, proteins, peptides, lipids, pigments, and polyphenols. Similarly, Montmorency tart cherry (Prunus cerasus L.) is high in anthocyanins and polyphenols. Both substances have antioxidant, anti-inflammatory, and vasodilatory properties that target mechanisms central to hypertension and cardiometabolic diseases.

Dietary interventions to improve cardiovascular health are highly sought after as they possess less risk and financial burden than pharmacological drugs. Previous randomized trial has shown that both brown seaweed and tart cherry supplementation can improving systolic blood pressure and other cardiovascular/ blood lipids. However, to date, no research has explored a seaweed - tart cherry blend using a placebo randomized intervention in patients with hypertension.

The primary purpose of the proposed investigation is to test the ability of a seaweed - tart cherry supplementation blend to improve cardiometabolic parameters in participants with mild-moderate hypertension using a pilot/ feasibility study.
