Robust statistically significant effects were found for improved diet , aerobic exercise , alcohol and sodium restriction , and fish oil supplements : mean reductions in systolic blood pressure of 5.0 mmHg [ 95 % confidence interval ( CI ) : 3.1 - 7.0 ] , 4.6 mmHg ( 95 % CI : 2.0 - 7.1 ) , 3.8 mmHg ( 95 % CI : 1.4 - 6.1 ) , 3.6 mmHg ( 95 % CI : 2.5 - 4.6 ) and 2.3 mmHg ( 95 % CI : 0.2 - 4.3 ) , respectively , with corresponding reductions in diastolic blood pressure .
Relaxation significantly reduced blood pressure only when compared with non-intervention controls .
We found no robust evidence of any important effect on blood pressure of potassium , magnesium or calcium supplements .
Available evidence does not support relaxation therapies , calcium , magnesium or potassium supplements to reduce blood pressure

Controlled trial of long term oral potassium supplements in patients with mild hypertension.
A 15 week r and omised double blind placebo controlled trial of oral potassium supplements ( 48 mmol daily ) was conducted in 37 patients who had mildly increased blood pressure and a normal dietary intake of sodium . After a two month run in and a one week baseline period the patients were r and omly assigned to receive either potassium supplements ( n = 18 ) or placebo ( n = 19 ) . By the third week of treatment blood pressure in the actively treated group had decreased significantly compared with that in the placebo group , though the decrease reached its maximum after 15 weeks . Urinary potassium excretion increased significantly in the group who received potassium supplements , but no significant changes were found in plasma sodium and potassium concentrations or in urinary sodium excretion . In a subgroup of 13 patients who underwent a further nine weeks of treatment with oral potassium supplements at half of the previous dose ( 24 mmol daily ) their blood pressure , at the end of this second study period , was still significantly lower compared with their baseline value but not with that of the placebo group . These results show that moderate oral potassium supplements are associated with a long term reduction in blood pressure in patients who have mild hypertension
