Magnesium is a vital mineral involved in over 300 biochemical reactions in the body. From supporting muscle and nerve function to improving sleep and reducing stress, it's no wonder magnesium supplements are increasingly popular. But with so many forms available, two often compared are Magnesium Glycinate and Magnesium Citrate.
In this article, we’ll explore the differences, benefits, side effects, and ideal uses of these two common magnesium supplements to help you make an informed choice.
What Is Magnesium Glycinate?
Magnesium glycinate is a chelated form of magnesium, where magnesium is bound to the amino acid glycine. This form is highly bioavailable, meaning it’s easily absorbed by the body. It's gentle on the stomach and less likely to cause laxative effects.
Benefits of Magnesium Glycinate:
-
Promotes Better Sleep: Glycine has calming effects on the brain and may enhance sleep quality.
-
Reduces Anxiety & Stress: Helps regulate neurotransmitters like GABA, known for promoting relaxation.
-
Supports Muscle Recovery: Aids in muscle relaxation, reducing cramps and spasms.
-
Gentle on Digestion: Ideal for those with sensitive stomachs.
What Is Magnesium Citrate?
Magnesium citrate combines magnesium with citric acid, making it highly absorbable and fast-acting. It's one of the most commonly used forms, especially for addressing constipation due to its natural laxative properties.
Benefits of Magnesium Citrate:
-
Relieves Constipation: Acts as a mild laxative, improving bowel movements.
-
Supports Muscle & Nerve Function: Like other forms of magnesium, it helps with muscle contraction and nerve signaling.
-
Fast Absorption: Quickly increases magnesium levels in the body.
Magnesium Glycinate vs Magnesium Citrate: Key Differences
| Feature | Magnesium Glycinate | Magnesium Citrate |
|---|---|---|
| Absorption | High | High |
| Stomach Sensitivity | Gentle | May cause loose stools |
| Primary Benefit | Sleep, stress, muscle recovery | Constipation relief |
| Best For | Anxiety, insomnia, muscle health | Occasional digestive issues |
| Laxative Effect | Rare | Common |
Potential Side Effects
Magnesium Glycinate:
-
Generally well-tolerated

Which One Should You Choose?
It depends on your health goals:
✅ Choose Magnesium Glycinate if:
-
You struggle with anxiety or poor sleep
-
You need long-term magnesium support
-
You’re sensitive to digestive side effects
✅ Choose Magnesium Citrate if:
-
You’re dealing with occasional constipation
-
You want a fast-acting supplement

Final Thoughts
Both magnesium glycinate and magnesium citrate have their place in health and wellness. Magnesium glycinate is excellent for stress, sleep, and muscle recovery, while magnesium citrate is best for short-term relief from constipation.
As always, speak with your healthcare provider before starting any supplement—especially if you have underlying health conditions or are taking medications.
