Up your intake of fresh fruits and vegetables and exercise for at least 30 minutes a day – even brisk walk will do. Regularly check the labels on processed foods – they usually contain a high amount of sodium which you will want to avoid. You may also want to try blood pressure supplements , like Blood Pressure Matrix. Vitamin D, folic acid potassium citrate and taurine (an antioxidant nutrient) have been well researched for their role in blood pressure maintenance. Herbs such as hawthorn leaves and natto-kinase (made from seaweeds) are known to promote healthy circulation and heart functions.
