The short answer
The best magnesium for heart health, briefly
Magnesium plays roles in muscle and nerve function, which includes the heart[1]. Taurate is marketed for cardiovascular support on the strength of taurine's presence in heart tissue — a mechanism story, not trial proof.
Given that, the sensible play is a well-tolerated form matched to the goal — taurate is the usual answer — or the 7-form blend if you'd rather not choose. Magnesium Breakthrough covers blood pressure and heart rhythm concerns plus six other forms in one capsule.
How we ranked these
Criteria, in order:
- Tolerance for the goal — a sleep pick must not be laxative; a digestion pick should be.
- Evidence status — stated honestly, including where it's thin.
- Label transparency — elemental mg disclosed beats proprietary blends that hide it.
- Value — elemental mg per dollar, not price per bottle.
For blood pressure and heart rhythm concerns: For heart concerns, the stakes are higher than any other goal here — this is firmly “talk to your doctor first” territory, not a self-supplementing category. Human evidence is thin for this goal, so tolerance, plausibility, and label honesty carry more of the weight.

Best single-form
Magnesium Taurate (single-form)
Magnesium taurate pairs the mineral with taurine, an amino sulfonic acid found in heart and muscle tissue. It is generally well tolerated and not notably laxative.

Budget pick
Magnesium Citrate (single-form)
Magnesium citrate pairs the mineral with citric acid. In a randomized, double-blind study it was found more bioavailable than several other preparations tested[2], and it is absorbed better than oxide[3].
- Form
- Citrate
- Tradeoff
- It has an osmotic effect in the gut: at higher doses it draws water into the bowel and can cause loose stools, which is why it doubles as an occasional-constipation remedy[4].

- Cheapest per bottle; check elemental mg per dollar

Bottom line
Which one should you buy?
Do not self-treat blood pressure or rhythm issues with a supplement. If your doctor is fine with magnesium as an adjunct, taurate is the conceptually matched form.
Magnesium Breakthrough is our best-overall pick: 7 forms, 500 mg elemental magnesium per serving.
Talk to your doctor before starting any supplement — especially with heart, blood pressure, blood sugar, or mood medications, or if you are pregnant or nursing.
Best magnesium for heart health: questions
What is the best magnesium for blood pressure and heart rhythm concerns?
Magnesium plays roles in muscle and nerve function, which includes the heart[1]. Taurate is marketed for cardiovascular support on the strength of taurine's presence in heart tissue — a mechanism story, not trial proof. On tolerance and practicality, taurate is the usual recommendation — it is generally well tolerated and not notably laxative.
Is a multi-form magnesium better than a single form for blood pressure and heart rhythm concerns?
Not proven better — but it removes the choosing problem. If you've tried one form and it didn't suit, a blend is a reasonable next experiment rather than a third single form. For blood pressure and heart rhythm concerns specifically: For heart concerns, the stakes are higher than any other goal here — this is firmly “talk to your doctor first” territory, not a self-supplementing category.
How do I compare prices fairly?
Divide the bottle price by total elemental mg (mg per serving × servings). That's the only apples-to-apples number. A cheap bottle with low elemental mg is often the expensive option.
Does magnesium lower blood pressure?
Small reductions show up in trials, mainly in people who were deficient. It's not a hypertension treatment — medication and lifestyle are.
What is taurine doing in a magnesium supplement?
Taurine is concentrated in heart muscle, which is the entire basis of taurate's heart-health marketing. The pairing is logical on paper, but human trials on magnesium taurate itself for heart outcomes are sparse — buy it for the concept, not the proof.
When should I talk to a doctor instead of shopping?
When blood pressure and heart rhythm concerns is new, severe, or persistent — supplements are for the mild, chronic, already-checked-out version of a problem. Talk to your doctor before starting any supplement — especially with heart, blood pressure, blood sugar, or mood medications, or if you are pregnant or nursing.
