Summary of the effects of vitamins (C, D, E) and minerals (calcium, magnesium, potassium) versus placebo on systolic and diastolic blood pressure.

Supplement	Systolic	Diastolic
Vitamin C	−1.45 mm Hg (−4.26, 1.35)	−0.47 mm Hg (−2.29, 1.34)
Vitamin D	−0.19 mm Hg (−0.71, 0.33)	+0.11 mm Hg (−0.47, 0.69)
Vitamin E	−1.76 mm Hg (−3.05, −0.47) *	+1.17 mm Hg (−0.51, 2.84)
Calcium	−1.37 mm Hg (−2.03, −0.71) *	−1.63 mm Hg (−2.70, −0.57) *
Magnesium	−2.79 mm Hg (−5.25, −0.34) *	−1.56 mm Hg (−3.03, −0.09) *
Potassium	−2.10 mm Hg (−3.81, −0.38) *	−1.28 mm Hg (−2.58, 0.02)

Values are mean systolic and diastolic blood pressure reductions for each supplement versus placebo with their corresponding 95% Confidence Intervals. Asterisks (*) denote statistical significance.
