The Comprehensive Guide to Magnesium Glycinate and Magnesium Citrate

Magnesium Glycinate and Magnesium Citrate

Magnesium is an essential mineral that plays a crucial role in various bodily functions, including muscle and nerve function, blood glucose control, and bone health. Two popular forms of magnesium supplements are magnesium glycinate and magnesium citrate. In this comprehensive guide, we will explore these two supplements in detail, helping you understand their differences, benefits, and which one might be best suited to your needs.

What Is Magnesium Glycinate?

Magnesium glycinate is a magnesium salt of glycine, an amino acid. It is often used as a dietary supplement to increase magnesium levels in the body. Here are some key aspects of magnesium glycinate:

Benefits of Magnesium Glycinate

  • Enhanced Absorption: Magnesium glycinate is known for its high bioavailability, which means it is easily absorbed by the body. This makes it an excellent choice for those with magnesium deficiency.
  • Gentle on the Stomach: Unlike some other magnesium supplements that may cause digestive discomfort, magnesium glycinate is gentle on the stomach, making it suitable for individuals with sensitive digestive systems.
  • Improved Sleep: Many people find that magnesium glycinate helps improve the quality of their sleep. It may promote relaxation and reduce insomnia symptoms.

Uses of Magnesium Glycinate

  • Muscle Relaxation: Magnesium plays a crucial role in muscle function, and magnesium glycinate can help relax muscles, making it beneficial for athletes and those with muscle cramps.
  • Stress Reduction: Some studies suggest that magnesium glycinate may have a calming effect on the nervous system, which can help reduce stress and anxiety.

What Is Magnesium Citrate?

Magnesium citrate is another widely used magnesium supplement, but it differs from magnesium glycinate in terms of its composition and uses. Let’s explore magnesium citrate in more detail:

Benefits of Magnesium Citrate

  • Effective Laxative: Magnesium citrate is commonly used as a laxative, as it can help soften stools and promote regular bowel movements. It is often recommended for constipation relief.
  • Kidney Stone Prevention: Some individuals with a history of kidney stones may benefit from magnesium citrate, as it may help prevent the formation of certain types of kidney stones.

Uses of Magnesium Citrate

  • Colon Cleansing: Before certain medical procedures or colonoscopies, healthcare providers may recommend a magnesium citrate solution to cleanse the colon.
  • Constipation Relief: If you’re struggling with occasional constipation, magnesium citrate can provide quick relief.

Magnesium Glycinate vs. Magnesium Citrate

Now, let’s dive deeper into the magnesium glycinate vs citrate debate to help you make an informed choice:

Absorption and Bioavailability

  • Magnesium Glycinate: This form boasts high bioavailability, ensuring that your body can absorb and utilize magnesium efficiently. It’s an excellent option for individuals looking to increase their magnesium levels effectively.
  • Magnesium Citrate: While still reasonably well-absorbed, magnesium citrate’s bioavailability is slightly lower than that of magnesium glycinate. However, it remains a solid choice for magnesium supplementation.

Digestive Tolerance

  • Magnesium Glycinate: It is gentle on the stomach and less likely to cause digestive discomfort, making it suitable for those with sensitive digestive systems.
  • Magnesium Citrate: In some cases, magnesium citrate may cause diarrhea or loose stools, especially when taken in high doses. Individuals with a history of digestive issues should be cautious.

Sleep Support

  • Magnesium Glycinate: This form is often favored for its potential to improve sleep quality. It may promote relaxation and reduce symptoms of insomnia, making it a go-to choice for those seeking better sleep.
  • Magnesium Citrate: While not typically used for its sleep-promoting effects, magnesium citrate can indirectly support sleep by aiding in overall well-being and relaxation.

Laxative Effect

  • Magnesium Glycinate: Unlike magnesium citrate, magnesium glycinate is not known for its laxative properties, which can be a deciding factor for those who want to avoid such effects.
  • Magnesium Citrate: This form is commonly used as a laxative and is effective at promoting bowel movements. It’s an option for individuals dealing with constipation.

Kidney Stone Prevention

  • Magnesium Glycinate: It is not specifically known for its role in kidney stone prevention.
  • Magnesium Citrate: Some studies suggest that magnesium citrate may help prevent certain types of kidney stones by inhibiting their formation.


Can I take magnesium glycinate and magnesium citrate together?

Yes, you can take these two supplements together, but it’s essential to monitor your magnesium intake to avoid excessive dosage. It’s advisable to consult a healthcare professional for personalized guidance.

Are there any side effects associated with magnesium supplements?

Both magnesium glycinate and magnesium citrate are generally safe when taken at recommended doses. However, excessive intake may lead to diarrhea, stomach cramps, or nausea. Always follow the recommended dosage on the product label.

Which form of magnesium is best for sleep?

Magnesium glycinate is often recommended for sleep support due to its calming effect on the nervous system. However, individual responses may vary, so it’s a good idea to try both forms and see which works best for you.

Can magnesium supplements interact with medications?

Magnesium supplements can interact with certain medications, such as antibiotics and diuretics. If you’re taking medication, consult your healthcare provider before adding magnesium supplements to your routine.

Is it safe to use magnesium supplements during pregnancy?

Pregnant women should consult their healthcare provider before taking any supplements, including magnesium. Proper prenatal care and nutrition are crucial during pregnancy, and magnesium intake should be monitored.

Can magnesium citrate help with weight loss?

While magnesium citrate is not a weight loss supplement, it can aid in weight management indirectly. Proper digestion and regular bowel movements are essential for a healthy metabolism, and magnesium citrate can support these processes.


In conclusion, both magnesium glycinate and magnesium citrate offer valuable benefits for various aspects of health. The choice between them depends on your specific needs and preferences. If you prioritize enhanced sleep and minimal digestive discomfort, magnesium glycinate may be your top pick. On the other hand, if you require an effective laxative or have a history of kidney stones, magnesium citrate could be more suitable.

By incorporating magnesium supplements into your daily routine, you can support various aspects of your health and well-being. Always remember to follow recommended dosages and consult with a healthcare professional when needed.
