Hydroxytyrosol Extreme (Olive Leaf Extract), 90 Veg Caps by ProHealth. Suitable for vegetarians. Dietary Supplement, 3rd Party Lab Tested, Safe Heavy Metal Tested, GMP Certified. Protects Cardiac and Endothelial Tissue. Human studies have shown that hydroxytyrosol supplementation decreases inflammatory markers and increases production of superoxide dismutase (SOD), the body’s own antioxidant, to reduce tissue damage. Promotes Healthy Blood Markers: Hydroxytyrosol metabolites attach to excess lipids in the blood and remove them, leading to a decrease in blood lipids. This reduction can reduce the immune response which is a key factor in aging-related damage to blood vessels. Decreases Free-Radical Burden: Hydroxytyrosol reduces excess free-radicals and nitric oxide, which are signaling molecules that can lead to DNA and protein damage. Additionally, it can activate certain anti-inflammatory proteins which can help improve tissue health in the blood vessels, digestive system, and liver. Supports DNA Health: Activates expression of the sirtuins through the same mechanisms as caloric restriction. In addition, hydroxytyrosol encourages the destruction of abnormal cells without inhibiting the function of healthy cells.
