Calcium, magnesium, and potassium have all shown some efficacy in the management of hypertension. In a double-blind, randomized crossover study, patients with mild to moderate primary hypertension were supplemented with 6CC mg per day of magnesium for six weeks. Oral magnesium significantly reduced the systolic, diastolic, and mean blood pressure.27 In another double-blind crossover study of magnesium supplementation ranging from 15-40 mmol per day, a significant decrease in the mean systolic blood pressure was recorded from while the mean diastolic blood pressure decreased from 100.2 = 4.2 mmHg to 92.0 = 6.6 mmHg.28 A study examined calcium carbonate supplementation at a dosage of 1.5 g per day in hypertensive patients for eight weeks. The results showed that the salt-sensitive hypertensive individuals had a significant blood pressure decrease.29 Another study showed that there was a significant linear decrease in systolic and diastolic blood pressure with increasing dairy calcium intake, and conversely with increasing blood pressure, there was a significant linear decrease in age-adjusted calcium intake from dairy sources.30 Additional analysis has shown that calcium supplementation (mean daily dose of 1,200 mg) reduced systolic BP by -1.86 mmHg and diastolic BP by 0.99 mmHg with a more profound impact in patients with a relatively low calcium intake.31
Potassium is also important in the prevention of hypertension. A meta-analysis of the studies performed showed that potassium supplementation is associated with a significant reduction in mean systolic blood pressure by -3.11 mmHg and diastolic blood pressure by -1.97 mmHg. The beneficial effects are more pronounced in individuals with low potassium and high sodium intake.32

Your heart pumps blood throughout your body using a network of tubing called arteries and capillaries which return the blood back to your heart via your veins. Blood pressure is the force of the blood pushing against the walls of your arteries as your heart beats.Learn more...
