Multivitamin and multimineral supplementation decreases systolic blood pressure in humans (WMD -1.31 mmHg, 95% CI -2.48 to -0.14 mmHg).
“MVMS had a lowering effect on systolic blood pressure (SBP) and diastolic blood pressure (DBP): the weighted mean difference (WMD) was -1.31 mmHg (95% CI, -2.48 to -0.14 mmHg)”
