Vitamin C supplementation: Vitamin C can help maintain the biological activity of nitric oxide and promote its synthesis in vascular endothelial cells. Vitamin C can be obtained from fruits and vegetables, such as oranges, strawberries, kiwis, tomatoes and peppers.
2. Exercise: Moderate exercise helps to increase the synthesis of nitric oxide, dilate blood vessels and lower blood pressure. It is recommended to do at least 150 minutes of aerobic exercise every week, such as jogging, brisk walking and swimming.
