Magnesium Taurate

Marketed as the "heart" magnesium on the strength of a 1996 hypothesis paper, not trial data. Magnesium as a class lowers blood pressure by about 2 mmHg; there is no controlled human trial showing the taurate salt does anything the cheaper salts do not.

What the science says

  • The cardiovascular rationale is a published hypothesis, not a finding Limited evidence

    The entire premise traces to a 1996 Medical Hypotheses paper arguing that magnesium and taurine have complementary vascular-protective actions and should therefore be combined. That is a mechanistic argument written to prompt research, and the confirmatory human research was never done.

  • Magnesium lowers blood pressure modestly — as any salt Moderate evidence

    A meta-analysis of 34 randomised double-blind placebo-controlled trials (2,028 participants) found a median 368 mg/day for a median 3 months reduced systolic BP by 2.00 mmHg (95% CI 0.43-3.58) and diastolic by 1.78 mmHg (95% CI 0.73-2.82). That effect belongs to magnesium, not to taurate, and is small relative to any antihypertensive drug.

  • Direct human data on the taurate salt are one uncontrolled study of a combination product Limited evidence

    A 2026 single-arm observational study gave 121 low-risk adults with elevated BP a magnesium taurate-potassium citrate product (121 mg elemental magnesium, 180 mg potassium) plus lifestyle counselling for 3 months, reporting roughly -11/-8 mmHg. With no control group, added lifestyle advice and potassium in the same capsule, nothing can be attributed to taurate; the authors say so explicitly. Everything else is rodent work, such as a 2019 study in cadmium-hypertensive rats.

Dosage & safety

Studied doseTypical products supply 100-250 mg elemental magnesium per day. Magnesium taurate is only about 9% elemental magnesium by weight, so a 1,000 mg dose gives roughly 90 mg elemental plus around 800 mg taurine — read labels carefully, because low elemental content is this form's real practical weakness. No dose has been established for the taurate salt specifically.
SafetyWell tolerated; taurate is among the gentler forms on the gut, and taurine itself is well tolerated to at least 3 g/day. Standard magnesium cautions apply: dose-dependent loose stools, and real hypermagnesemia risk in advanced kidney disease. Separate by 2 hours from tetracyclines, quinolones, bisphosphonates and levothyroxine. Neither magnesium nor taurine is prohibited in sport.
