Magnesium Glycinate vs Citrate: What's the Difference?
Magnesium is an essential mineral involved in hundreds of biochemical processes in the body. When choosing a magnesium supplement, one of the most common questions is: what is the difference between magnesium glycinate and magnesium citrate? This guide compares the two forms based on their composition, elemental magnesium content, format, texture, and manufacturer guidance — without making treatment claims or prescribing dosing.
Please note: Always follow the directions on the product label and consult a qualified healthcare professional before starting any new supplement, particularly if you have an existing health condition, are pregnant, or are taking medication.
What Is Magnesium Glycinate?
Magnesium glycinate is a chelated form of magnesium, meaning the magnesium mineral is bound to glycine — a non-essential amino acid. The chelation process creates a stable compound that is widely used in professional-grade supplement formulations.
Key characteristics:
- Form: Chelated mineral (magnesium bound to glycine)
- Elemental magnesium content: Typically lower percentage by weight compared to citrate, as glycine is a larger molecule — though the actual amount per serving depends on the manufacturer's formulation
- Format: Commonly available as capsules
- Texture/taste: No taste when taken in capsule form; glycinate is generally considered mild
- Manufacturer guidance: Pure Encapsulations recommend taking with food

What Is Magnesium Citrate?
Magnesium citrate is formed by combining magnesium with citric acid. It is one of the most widely studied and commonly used forms of supplemental magnesium.
Key characteristics:
- Form: Organic salt (magnesium bound to citric acid)
- Elemental magnesium content: Approximately 16% elemental magnesium by weight — meaning a 200 mg capsule of magnesium citrate delivers roughly 32 mg of elemental magnesium; actual amounts per serving vary by product
- Format: Available as capsules and powder
- Texture/taste: Citrate has a mild, slightly tart taste when taken in powder form; neutral in capsule form
- Manufacturer guidance: Pure Encapsulations recommend taking with food

Side-by-Side Comparison
| Feature | Magnesium Glycinate | Magnesium Citrate |
|---|---|---|
| Form | Chelated (magnesium + glycine) | Organic salt (magnesium + citric acid) |
| Elemental Mg % | Lower (glycine is a larger molecule) | ~16% by weight |
| Format available | Capsules | Capsules & powder |
| Taste/texture | Neutral (capsule) | Neutral (capsule); slightly tart (powder) |
| Take with food? | Yes (manufacturer guidance) | Yes (manufacturer guidance) |
Which Form Is Right for You?
Both magnesium glycinate and magnesium citrate are established forms of supplemental magnesium used in professional supplement ranges. The right choice depends on individual factors — including any existing health conditions, dietary considerations, and personal preferences around format and texture — and will vary from person to person.
We do not make health claims about either product. We recommend:
- Reading the full product label carefully before use
- Consulting a qualified healthcare professional or registered nutritionist for personalised guidance
- Considering format preference (capsules vs powder) as a practical starting point if you are undecided
