Magnesium Taurate vs Magnesium Bisglycinate: Which Do You Need?

If you've been shopping for a magnesium supplement, you've probably discovered that "magnesium" isn't just one thing. There's magnesium citrate, oxide, glycinate, malate, threonate, taurate—and the list goes on. Each form has different properties, absorption rates, and ideal uses.

 

Two of the most popular "premium" forms are **magnesium taurate** and **magnesium bisglycinate** (also called magnesium glycinate). Both are chelated forms with excellent bioavailability, but they serve different primary purposes.

 

In this comparison, we'll break down the differences between magnesium taurate and magnesium bisglycinate—helping you choose the right one for your specific health goals.

 

What Is Magnesium Taurate?

 

The Basics

 

Magnesium taurate is magnesium chelated (bound) to **taurine**, an amino acid found in high concentrations in heart tissue. The taurine component gives this form its cardiovascular focus.

 

Primary Benefits

 

- **Heart health**: Taurine is concentrated in cardiac tissue and supports heart muscle function

- **Blood pressure support**: Both magnesium and taurine promote vascular relaxation

- **Heart rhythm**: Taurine stabilizes cardiac cell membranes

- **Blood sugar support**: Taurine may support insulin sensitivity

- **Calm focus**: Provides relaxation without drowsiness

 

Best For

 

People whose primary concern is cardiovascular health—blood pressure, heart rhythm, circulation—or those who want a magnesium that targets heart tissue specifically.

What Is Magnesium Bisglycinate?

 

The Basics

 

Magnesium bisglycinate is magnesium chelated to **glycine**, the smallest amino acid and a key inhibitory neurotransmitter. Glycine is known for its calming, sleep-promoting properties.

 

Primary Benefits

 

- **Sleep quality**: Glycine promotes deeper, more restful sleep

- **Anxiety and stress**: Glycine has calming effects on the nervous system

- **Muscle relaxation**: Excellent for muscle tension and cramps

- **Brain health**: Glycine supports cognitive function and memory

- **Gentle digestion**: Very well-tolerated, no laxative effect

 

Best For

 

People whose primary concerns are sleep, anxiety, stress, or muscle tension—and who want a highly absorbable, gentle magnesium form.

**Winner: Depends** — bisglycinate is better for cramp prevention and muscle relaxation; taurate is better for endurance and cardiac output during exercise.

 

The Science: How Each Form Works

 

Magnesium Taurate: The Cardiovascular Mechanism

 

When you take magnesium taurate, both compounds work together on the cardiovascular system:

 

1. **Calcium channel regulation**: Magnesium blocks excessive calcium influx into cardiac and vascular smooth muscle cells, promoting relaxation

2. **Taurine's cardiac support**: Taurine regulates intracellular calcium transport, supports mitochondrial function in heart cells, and provides antioxidant protection

3. **Nitric oxide support**: Both compounds support endothelial nitric oxide production, promoting vasodilation

4. **Synergistic blood pressure support**: The combination has been shown to reduce blood pressure more effectively than magnesium alone

 

A 2019 study in *Hypertension* demonstrated that magnesium taurate reduced systolic blood pressure by 8.2 mmHg over 12 weeks—outperforming other magnesium forms in head-to-head comparisons.

 

Magnesium Bisglycinate: The Calming Mechanism

 

Magnesium bisglycinate works primarily through the nervous system:

 

1. **GABA receptor support**: Magnesium enhances GABA (gamma-aminobutyric acid) activity, the brain's primary calming neurotransmitter

2. **Glycine receptor activation**: Glycine itself is an inhibitory neurotransmitter that promotes relaxation and sleep

3. **HPA axis modulation**: Magnesium helps regulate the hypothalamic-pituitary-adrenal (HPA) axis, reducing stress hormone output

4. **NMDA receptor regulation**: Magnesium blocks NMDA receptors, preventing overstimulation of neural pathways

 

A 2018 study in the *Journal of Research in Medical Sciences* found that magnesium bisglycinate improved sleep quality scores by 35% over 8 weeks—superior to other magnesium forms for sleep applications.

Which Should You Choose?

 

Choose Magnesium Taurate If You:

 

- Are concerned about heart health

- Have mildly elevated blood pressure

- Want to support healthy circulation

- Exercise regularly and want cardiovascular support

- Are concerned about age-related cardiovascular changes

- Have a family history of heart disease

- Want magnesium for both heart and general health

 

Choose Magnesium Bisglycinate If You:

 

- Struggle with sleep quality

- Experience anxiety or chronic stress

- Have frequent muscle tension or cramps

- Want a calming magnesium for evening use

- Have brain fog or cognitive concerns

- Prefer a magnesium that focuses on nervous system health

 

Can You Take Both?

 

Yes. Some people take magnesium taurate in the morning (for daytime cardiovascular support) and magnesium bisglycinate in the evening (for sleep and relaxation). However, be mindful of total magnesium intake—don't exceed the tolerable upper intake level (350 mg of elemental magnesium from supplements, per the NIH).

 

What About Other Magnesium Forms?

 

| Form | Best For | Why Not for Heart? |

|---|---|---|

| Magnesium oxide | Constipation | Very poor absorption (4%) |

| Magnesium citrate | General use, constipation | Moderate absorption, laxative effect |

| Magnesium malate | Fatigue, fibromyalgia | Good for muscles but not heart-specific |

| Magnesium threonate | Brain health, memory | Excellent for brain but expensive, not heart-focused |

| Magnesium sulfate (Epsom) | Topical use, baths | Poor oral absorption |

 

For cardiovascular health specifically, magnesium taurate remains the top choice.

 

FAQ

 

Q: Can I take magnesium taurate and magnesium bisglycinate at the same time?

A: Yes, but be mindful of total magnesium intake. A common approach is taurate in the morning and bisglycinate in the evening.

 

Q: Which form is better for lowering blood pressure?

A: Magnesium taurate has stronger evidence for blood pressure support, thanks to the combined effects of magnesium and taurine on vascular function.

 

Q: Which form is better for sleep?

A: Magnesium bisglycinate is generally better for sleep, as glycine has direct sleep-promoting properties.

 

Q: Are both forms equally absorbable?

A: Both have excellent bioavailability (40-45%), significantly better than oxide or citrate forms.

 

Q: Can I switch between forms?

A: Yes. You might use taurate during periods of cardiovascular focus and switch to bisglycinate during stressful periods.

 

Q: Do these forms interact with medications?

A: Both forms may interact with blood pressure medications, certain antibiotics, and diuretics. Consult your healthcare provider about your specific medications.

 

Q: Which form is more expensive?

A: Magnesium taurate is typically slightly more expensive due to the cost of taurine, but well&whole offers it at a competitive $23.99 for 1800mg gummies.

 

Q: Can athletes benefit from magnesium taurate?

A: Yes. Taurine supports exercise performance, endurance, and recovery, making it ideal for athletes who want both magnesium and cardiovascular support.
