Magnesium Glycinate VS Citrate is one of the most important minerals in our body. It supports muscle and nerve function, keeps our heart healthy, and helps produce energy. But when choosing a magnesium supplement, you might wonder — which form is better: magnesium glycinate or magnesium citrate?
This article explains the difference between these two forms, their benefits, side effects, and how to decide which one suits your needs best.
1. What Is Magnesium?
Magnesium is a mineral that plays a vital role in more than 300 chemical reactions in the body. It helps with:
- Muscle movement
- Heart rhythm
- Nerve signals
- Bone strength
- Energy production
Because of modern diets and stress, many people don’t get enough magnesium from food. That’s why supplements like magnesium glycinate and magnesium citrate are popular options.
2. Understanding Magnesium Glycinate
Magnesium glycinate is made by combining magnesium with the amino acid glycine. This form is known for being gentle on the stomach and easy to absorb.
Benefits of Magnesium Glycinate:
- Improves sleep quality: Glycine promotes relaxation, helping you fall asleep faster.
- Reduces anxiety and stress: It supports calmness and reduces nervous tension.
- Less likely to cause diarrhea: Unlike some other forms, it’s easy on digestion.
- Helps with chronic pain and muscle cramps: Good for those with fibromyalgia or muscle tension.
Magnesium glycinate is often recommended for people with sensitive stomachs or those who need to take magnesium long-term.
3. Understanding Magnesium Citrate
Magnesium citrate is a combination of magnesium and citric acid. This form is also highly absorbable but works differently from glycinate.
Benefits of Magnesium Citrate:
- Improves digestion: Acts as a gentle laxative and relieves constipation.
- Supports muscle and nerve health: Helps prevent cramps and stiffness.
- Boosts energy levels: Aids in converting food into energy.
- Good absorption: Easily absorbed by the intestines.
Because of its digestive benefits, magnesium citrate is often used by people who suffer from irregular bowel movements or occasional constipation.

5. How to Choose the Right One
Your choice depends on your health goals and how your body reacts to supplements.
- Choose magnesium glycinate if you:
- Have trouble sleeping
- Suffer from stress or anxiety
- Have a sensitive stomach
- Want a long-term magnesium source
- Choose magnesium citrate if you:
- Struggle with constipation
- Need quick absorption
- Want better energy and digestion
If you are unsure, start with magnesium glycinate because it’s usually well tolerated and safe for most people.
6. Possible Side Effects
While magnesium is safe for most adults, taking too much of any form can cause problems.
Common side effects may include:
- Loose stools (especially with magnesium citrate)
- Stomach upset
- Nausea (in rare cases)
Always start with a low dose and increase gradually. It’s best to take magnesium with food to improve absorption and reduce stomach discomfort.
If you have kidney problems or are taking medications, talk to your doctor before using magnesium supplements.
7. Natural Food Sources of Magnesium
Even if you take supplements, it’s great to include magnesium-rich foods in your diet:
- Leafy green vegetables (spinach, kale)
- Nuts and seeds (almonds, pumpkin seeds)
- Whole grains (brown rice, oats)
- Bananas
- Dark chocolate
- Legumes (beans, lentils)
A mix of these foods and a suitable magnesium supplement can help maintain healthy magnesium levels.
8. How to Take Magnesium Supplements
Here are a few simple tips for taking magnesium:
- Take it with meals to improve absorption.
- Avoid taking it with high-dose calcium supplements (they may compete for absorption).
- Take magnesium glycinate before bedtime for better sleep.
- Take magnesium citrate in the morning if you want to support digestion.
9. Which Is More Effective?
Both magnesium glycinate and citrate work well — it depends on your needs.
- For calming the body and mind, glycinate is more effective.
- For relieving constipation or digestive issues, citrate is better.
There is no “one-size-fits-all” option, but both forms offer great benefits when used correctly.
