Top 6 studies

  1. Meta-analysis Simental-Mendia LE, Sahebkar A, Rodriguez-Moran M, Guerrero-Romero F, Pharmacol Res 2016 · n=2,028

    Oral magnesium supplementation reduces the risk of metabolic syndrome: a meta-analysis of randomized controlled trials PMID 27393444

    Magnesium supplementation significantly improved metabolic syndrome parameters

  2. RCT Katakawa M et al., Hypertens Res 2016

    Taurine and magnesium supplementation enhances the function of endothelial progenitor cells through antioxidation in healthy men and spontaneously hypertensive rats PMID 27412799

    Taurine and magnesium supplementation increased endothelial progenitor cell colony formation in healthy men and improved impaired EPC function in hypertensive rats through antioxidation.

  3. Review McCarty MF, Med Hypotheses 1996

    Complementary vascular-protective actions of magnesium and taurine: a rationale for magnesium taurate PMID 8692051

    Taurine lowers blood pressure, retards atherogenesis, prevents arrhythmias, and stabilizes platelets -- effects parallel to magnesium; combined magnesium taurate has considerable cardiovascular protective potential.

  4. Review McCarty MF, Med Hypotheses 1996

    Taurine and magnesium co-supplementation for cardiovascular protection PMID 8692034

    Combined magnesium and taurine may synergistically support cardiovascular function

  5. Meta-analysis Argeros Z, Xu X, Bhandari B et al., Hypertension (Dallas, Tex. : 1979) 2025

    Magnesium Supplementation and Blood Pressure: A Systematic Review and Meta-Analysis of Randomized Controlled Trials PMID 41000008

  6. Meta-analysis Veronese N et al., Eur J Nutr 2019

    Magnesium and health outcomes: an umbrella review of systematic reviews and meta-analyses of observational and intervention studies PMID 30684032

    Strong evidence that magnesium supplementation decreases risk of hospitalization in pregnant women and reduces migraine intensity/frequency; beneficial for blood pressure.

Contrary evidence

What pushes back.

Caveats, null findings, and methodological limits that hold the tier where it is.

What argues against the claim

  • Effect is small (about 2 mmHg systolic on average).
  • Larger effects appear in deficient or pre-hypertensive subgroups.

Recommendation

What the evidence supports.

What we recommend, with caveats

300 to 500 mg/day chelated magnesium as an adjunct, not a replacement, for diagnosed hypertension. Coordinate with your physician if you take BP medication.
