Antioxidants prevent damage to the kidney vasculature, including both large and small blood vessels. By preventing inflammatory processes in the vasculature, they contribute to the prevention of atherosclerosis and narrowing of blood vessels. In this way, they help prevent the development of high blood pressure.

If high blood pressure is already present, they help stop the disease processes in the vasculature, leading to a stable form of arterial hypertension that can be managed with medication. In certain cases, by stopping the inflammatory process, high blood pressure can even normalize without medication, especially if a person opts for a lifestyle change that includes healthy physical activity and a healthy, balanced diet.
