Magnesium taurate is an oral magnesium salt that supplies taurine. Blood-pressure and fasting-glucose effects are those of absorbable magnesium salts, not this salt alone. Direct human evidence is a single study with no comparison group. Main harms are loose stool and magnesium buildup when kidneys cannot clear it. Reasonable for blood pressure plus taurine; not a separately proven longevity agent. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Serum magnesium | 2.0–2.3 mg/dL (0.82–0.95 mmol/L) | Confirms the oral load is landing and not overshooting |
| RBC magnesium | Track change from that person’s baseline; no established functional target | Some clinics use it as a tissue proxy; not a validated surrogate |
| eGFR (creatinine or cystatin C) | ≥60 mL/min/1.73 m² to continue unsupervised oral magnesium | Gates hypermagnesemia risk |
| Home blood pressure | Individual target, often <120/80 mm Hg if tolerated | The main clinical surrogate this salt is chosen for |
| Fasting glucose or HbA1c | Fasting glucose 70–90 mg/dL if pursuing metabolic optimization; HbA1c as that person’s trend | Class magnesium signal is glucose, not HbA1c |
| Serum potassium | 4.0–4.5 mmol/L when stacked with potassium citrate or sparing diuretics | Dual-cation retention in low eGFR |
Cadence: Baseline, then 4 weeks, then every 3–6 months while the dose is stable, or sooner if a diuretic, acid-suppressing drug, or antihypertensive is added
