Supplements
Magnesium taurate combines magnesium with taurine, an amino acid with its own cardiovascular research. Both ingredients are individually well supported; the combination itself has almost no direct human trial evidence. Our top pick is KAL Magnesium Taurate 400 mg with Vitamin B6. It is a reasonable, well-tolerated form — not a proven heart supplement.
How We Picked
We looked for clear elemental magnesium disclosure, meaningful taurine content rather than a token amount, and formulations from brands with established quality records. Products that bury the magnesium figure behind a large compound weight were down-weighted, as were complexes where taurate is one small component of a blend.
A. KAL Magnesium Taurate 400 mg with Vitamin B6 — Best Overall
KAL Magnesium Taurate 400 mg with Vitamin B6
KAL
- 400 mg magnesium taurate per serving
- Includes vitamin B6
- Long-established supplement brand
- Consistent tablet potency
- Widely available and well reviewed
Why we picked it: Vitamin B6 is involved in magnesium transport into cells and is a sensible inclusion rather than filler. KAL has been making this formula for years, and consistency matters more than novelty for a mineral you take daily.
B. Cardiovascular Research Magnesium Taurate 125 mg — Best Low Dose
Cardiovascular Research Magnesium Taurate 125 mg
Cardiovascular Research
- 125 mg per capsule
- Easy to titrate up or down
- Simple two-ingredient formula
- Long-running speciality product
- Useful for sensitive stomachs
Why we picked it: Smaller capsules are genuinely useful with magnesium, because tolerance varies and the difference between a comfortable dose and digestive upset can be small. Starting low and adding capsules is more sensible than starting high and stopping.
C. NatureBell Magnesium Taurate — Best Value
NatureBell Magnesium Taurate
NatureBell
- 240 capsules per bottle
- Several months at typical dosing
- Third-party tested
- No artificial fillers
- Lowest cost per serving of our picks
Why we picked it: Magnesium is a long-horizon supplement and a large bottle reduces the friction of reordering. As always, check the supplement facts panel for elemental magnesium rather than relying on the compound weight in the product name.
What Magnesium Taurate Is
Magnesium taurate is magnesium bound to taurine, a sulfur-containing amino acid that is abundant in heart and muscle tissue. As a chelated form it is well absorbed and, like other chelates, produces less laxative effect than magnesium oxide or citrate. The appeal is the pairing: both magnesium and taurine independently have research connecting them to cardiovascular function, so combining them looks compelling on paper.
The Honest State of the Evidence
Here is what is fair to say. Magnesium supplementation has meta-analysis support for modest reductions in blood pressure, and low magnesium status is associated with cardiovascular risk. Taurine has its own randomized trial evidence, including studies reporting blood pressure reductions at gram-scale doses. What does not exist is a meaningful body of human trials on magnesium taurate specifically. The form was proposed in a 1990s hypothesis paper as a cardiovascular-targeted magnesium, and the marketing has run far ahead of the research ever since. It is a plausible combination of two well-supported ingredients, not a validated intervention.
The Taurine Dose Problem
Taurine trials that reported blood pressure effects typically used 1.5 to 3 grams per day. A magnesium taurate capsule supplies taurine as part of the chelate, and the amount is usually a fraction of that — often a few hundred milligrams at most. If your interest is specifically in taurine's cardiovascular effects, magnesium taurate is an inefficient way to get there; a separate taurine supplement delivers far more. Magnesium taurate makes more sense as a well-tolerated magnesium with a small taurine bonus than as a taurine delivery system.
Dosing and Elemental Content
As with every magnesium product, read the elemental magnesium line rather than the compound weight. A product described as "magnesium taurate 400 mg" typically delivers a much smaller amount of actual magnesium. Adult recommended intake is roughly 400 to 420 mg daily for men and 310 to 320 mg for women from all sources, and supplemental magnesium carries a 350 mg per day upper level based on laxative effect. Most people do well with 200 to 400 mg of elemental magnesium, taken with food.
Who It Suits, and Safety
Magnesium taurate is a sensible pick if you tolerate chelated magnesium well and like the idea of the taurine pairing. If your priority is sleep, glycinate has the better rationale; if it is constipation, citrate is more effective; if it is cognitive support, L-threonate is the form with relevant research. Magnesium is generally very safe in healthy adults, with loose stools the main dose-limiting effect. People with kidney impairment should not supplement magnesium without medical supervision, since impaired clearance can allow it to accumulate.

Frequently Asked Questions
What is magnesium taurate good for?
It is a well-absorbed, well-tolerated form of magnesium that also supplies some taurine. Magnesium itself has meta-analysis support for modest blood pressure reduction and for normal muscle and nerve function. Taurine separately has trial evidence for blood pressure at gram-scale doses. Direct human trials of magnesium taurate as a combination are essentially absent.
Is magnesium taurate good for the heart?
The rationale is plausible but not proven. Both magnesium and taurine have individual research linking them to cardiovascular measures, and the form was proposed in the 1990s specifically as a cardiovascular-targeted magnesium. There is no meaningful body of human trials on magnesium taurate itself, and the taurine dose per capsule is far below the amounts used in taurine trials.
How much magnesium taurate should I take?
Read the elemental magnesium figure on the supplement facts panel rather than the compound weight in the product name. Most people do well with 200 to 400 mg of elemental magnesium daily, taken with food. Supplemental magnesium has a tolerable upper intake level of 350 mg per day, set because of laxative effects.
Magnesium taurate or magnesium glycinate?
Both are well-absorbed chelates with low laxative effect, and no head-to-head trial separates them. Glycinate has the better rationale for sleep and calm, since glycine is mildly calming and is used at gram doses in sleep research. Taurate is chosen for its cardiovascular association. Tolerance and price are reasonable deciding factors.

Dosage Reference
Adult RDA for magnesium is approximately 400–420 mg/day (men) and 310–320 mg/day (women) from all sources; supplemental magnesium has a tolerable upper intake level of 350 mg/day. Most people use 200–400 mg elemental magnesium daily with food. Note that taurine trials showing blood pressure effects used 1.5–3 g/day, far more taurine than magnesium taurate capsules supply. People with kidney impairment should not supplement magnesium without medical supervision.
