Magnesium taurate benefits are primarily centered on cardiovascular and neurological health, making it one of the more targeted magnesium supplement forms. 1 This synergistic combination is one reason magnesium taurate is preferred by some clinicians for people with cardiovascular concerns, though all forms of magnesium share the broad benefits of magnesium replenishment.

What Is Magnesium Taurate
Magnesium taurate is a chelated form of magnesium in which magnesium ions are bound to taurine molecules. Chelation generally improves mineral bioavailability and reduces gastrointestinal side effects compared to inorganic salts like magnesium oxide.
Taurine (2-aminoethanesulfonic acid) is one of the most abundant amino acids in the body, particularly concentrated in the heart, brain, retina, and skeletal muscle. 1
The combination of magnesium and taurine is particularly relevant to cardiovascular health, as both compounds independently support blood pressure regulation, heart rhythm, and protection against oxidative stress.
Key Magnesium Taurate Benefits
Cardiovascular Support
Magnesium taurate's most distinct potential benefit is cardiovascular protection. Magnesium is essential for the regulation of heart muscle contractions and the transmission of electrical impulses through cardiac tissue. Deficiency is associated with arrhythmias, hypertension, and increased risk of cardiovascular events.
Taurine independently modulates the movement of ions (calcium, potassium, sodium) in cardiac cells, supporting normal heart rhythm. Animal research has shown taurine supplements reduce blood pressure through effects on the renin-angiotensin system. 2
Blood Pressure Regulation
Both magnesium and taurine are independently associated with lower blood pressure. Magnesium promotes vasodilation through nitric oxide signaling and reduces vascular smooth muscle tone. Taurine modulates sympathetic nervous system activity that drives blood pressure elevation.
Nervous System and Anxiety Support
Both magnesium and taurine have calming effects on the nervous system. Magnesium acts as a natural NMDA receptor antagonist and supports GABA receptor function — mechanisms that reduce neural excitability and anxiety. Taurine also interacts with GABA and glycine receptors, contributing to reduced nervous system hyperactivity.
Research suggests magnesium deficiency is associated with increased anxiety and stress reactivity. 2 For additional context on heart palpitations, see heart palpitations causes and when to worry.
Blood Sugar Regulation
Magnesium plays a critical role in insulin signaling and glucose metabolism. Adequate magnesium intake is associated with a lower risk of type 2 diabetes, and magnesium supplementation may improve insulin sensitivity in people who are deficient. 4
Sleep Quality
Magnesium supports the production of melatonin and activates GABA receptors that are necessary for sleep. While magnesium glycinate is more commonly recommended for sleep specifically, magnesium taurate may offer comparable sleep support alongside its cardiovascular benefits, particularly for people who experience sleep disturbance alongside heart palpitations or anxiety.
Magnesium Taurate vs. Other Magnesium Forms
There are many forms of magnesium supplement, each with different properties:
- Magnesium taurate: Best for cardiovascular and neurological support; good bioavailability; gentle on digestion
- Magnesium glycinate benefits for sleep and anxiety: Best for sleep, anxiety, and general magnesium replenishment; excellent bioavailability; gentlest on digestion
- Magnesium threonate benefits for brain and memory: Best for brain and cognitive health; crosses the blood-brain barrier most effectively
- Magnesium citrate: Good bioavailability; commonly used; can have a laxative effect at higher doses
- Magnesium oxide: Poor bioavailability; primarily used as a laxative
- Magnesium malate benefits for energy and muscle pain: Good for energy and muscle fatigue
- Magnesium chloride: Good bioavailability; also available as a topical form1
Magnesium taurate is a strong choice for cardiovascular health, but it is generally more expensive and less widely available than magnesium citrate or glycinate.
Dosage and Safety
The recommended dietary allowance (RDA) for magnesium is 310–320 mg/day for women and 400–420 mg/day for men. Most magnesium taurate supplements provide 100–200 mg elemental magnesium per serving.
Magnesium from food and supplements is generally safe. The tolerable upper intake level (UL) for supplemental magnesium is 350 mg/day for adults. Exceeding this from supplements may cause diarrhea, nausea, and cramping. The UL applies to supplements, not dietary magnesium.
People with kidney disease should use magnesium supplements with caution, as impaired kidneys cannot efficiently excrete excess magnesium, which can lead to magnesium toxicity. 5
Magnesium may interact with certain antibiotics (tetracyclines, fluoroquinolones), bisphosphonates, and diuretics.
When to See a Doctor
Consult a healthcare provider before supplementing with magnesium taurate if:
- You have kidney disease or reduced kidney function
- You take diuretics, antibiotics, or medications for heart conditions
- You have symptoms of significant magnesium deficiency: severe muscle cramps, cardiac arrhythmias, or neurological symptoms
- You are considering high-dose magnesium supplementation
A serum magnesium blood test can help identify deficiency, though it reflects only about 1% of total body magnesium and may appear normal despite functional deficiency. 3
Frequently asked questions
What is magnesium taurate best for?
Magnesium taurate is particularly suited for cardiovascular health — including blood pressure regulation, heart rhythm support, and protection against cardiac stress — due to the synergistic effects of both magnesium and taurine on the heart and blood vessels. It is also useful for nervous system and anxiety support.
Is magnesium taurate better than magnesium glycinate?
Neither is universally better — they have different strengths. Magnesium glycinate is the most commonly recommended form for sleep, relaxation, and general magnesium replenishment. Magnesium taurate offers more specific cardiovascular support from taurine. For people with both cardiovascular concerns and sleep issues, some practitioners recommend taking both or alternating.
Does magnesium taurate cause diarrhea?
Compared to inorganic forms such as magnesium oxide or magnesium sulfate, chelated forms including magnesium taurate are significantly less likely to cause diarrhea. At recommended doses, most people tolerate it well. Very high doses may still cause loose stools.
Can magnesium taurate help with anxiety?
Both magnesium and taurine have evidence for reducing nervous system excitability and anxiety-related symptoms. Magnesium acts through GABA and NMDA receptors, and taurine has calming effects through similar pathways. Magnesium taurate may be particularly helpful for anxiety that is accompanied by heart palpitations or elevated blood pressure.
When is the best time to take magnesium taurate?
Magnesium taurate can be taken at any time of day. Many people take it in the evening to support sleep and take advantage of its calming effects. It can be taken with or without food, though taking it with food may reduce any potential GI discomfort.
