Is Magnesium Glycinate the Same as Magnesium Bisglycinate?

When shopping for magnesium supplements, you might notice two names that look almost identical: Magnesium Glycinate and Magnesium Bisglycinate.
It’s easy to wonder — are they the same thing, or is there a difference you should know about?

Let’s break it down so you can make the best choice for your health.

1. Understanding Magnesium Chelates

Both magnesium glycinate and magnesium bisglycinate are forms of magnesium bound to the amino acid glycine. This bonding process is called chelation and is designed to improve absorption and reduce the digestive discomfort sometimes caused by other magnesium forms (like magnesium oxide).

2. Is There a Difference Between the Two?

Here’s the secret: Magnesium glycinate and magnesium bisglycinate are essentially the same compound.
The difference lies mainly in naming conventions:

• Magnesium Glycinate – often used as a general term for magnesium bound to glycine.
• Magnesium Bisglycinate – specifies that two glycine molecules are bound to each magnesium ion (which is what magnesium glycinate is).

So, in most supplement labels, these names are interchangeable — both refer to the same highly absorbable, gentle-on-the-stomach form of magnesium.

3. Why Choose Magnesium (Bis)Glycinate?

This form of magnesium is popular for a reason:

• Highly absorbable – ideal if you want maximum benefit from your supplement.
• Gentle on digestion – far less likely to cause loose stools compared to other magnesium types.
• Supports relaxation & sleep – glycine itself has calming effects on the brain.
• Muscle & nerve support – magnesium plays a role in muscle relaxation, nerve function, and energy production.

4. Who Might Benefit Most?

Magnesium bisglycinate is often chosen by:

• People with sensitive stomachs.
• Those wanting to support better sleep and relaxation.
• Anyone looking to maintain healthy muscles and nerves.
• People whose diets are low in magnesium-rich foods (like leafy greens, nuts, and seeds).

5. Quality Matters — Choosing the Right Supplement

Not all magnesium supplements are created equal. Look for:

• Pure magnesium bisglycinate with no unnecessary fillers.
• A trusted brand that clearly lists dosage and form.
• Third-party testing for quality and purity.

💡 At Healthy Living, we stock high-quality PrizMAG Magnesium Bisglycinate — free from magnesium oxide, gluten, and other additives, making it one of the purest options available.

6. The Bottom Line

Magnesium glycinate and magnesium bisglycinate are essentially the same form of magnesium — both are excellent choices if you want a gentle, well-absorbed supplement.
The key is to choose a trusted brand so you can be confident in what you’re taking.
