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
PURPOSE To quantify effectiveness of lifestyle interventions for hypertension .
Nutritional magnesium supplementation does not change blood pressure nor serum or muscle potassium and magnesium in untreated hypertension. A double-blind crossover study.
The aim of this study was to evaluate if a nutritional dose of magnesium given orally changes the blood pressure in untreated hypertensive patients and if orally-given magnesium had any influence on serum and muscle magnesium and potassium . A r and omized , double-blind crossover study design was followed with magnesium 15 mmol/day or placebo treatment for two months . Thirty-nine patients aged 20 - 59 years , were treated . Sample s for magnesium and potassium in blood , muscle and urine were taken at entry time , after two months ( crossover time ) and after four months ( end of study ) . Systolic and diastolic supine and st and ing blood pressures were measured at the same times . No significant change in blood pressure , serum or muscle concentrations of electrolytes were observed on magnesium treatment . Urine magnesium rose significantly on magnesium , and it decreased significantly on placebo . Therefore results suggest that 15 mmol magnesium/day , given to untreated mild-to-moderate hypertensives does not alter blood pressure nor the concentrations of magnesium and potassium in serum and muscle , in patients with normal magnesium turnover
