What Are the Benefits of Magnesium Glycinate

magnesium glycinate benefits

Magnesium Glycinate is a highly bioavailable form of magnesium that is known for its gentle effect on the digestive system, making it a popular choice for those with sensitive stomachs.

Additionally, glycine, the amino acid bound to magnesium in this form, is often taken as a sleep aid and for its calming properties.

As per EFSA-approved health claims, magnesium contributes too:

  • Reduction of Tiredness & Fatigue - Magnesium plays a vital role in supporting electrolyte balance and normal energy-yielding metabolism to help reduce tiredness and fatigue.
  • Normal Nervous System & Psychological Function: Magnesium supports the normal functioning of the nervous system and promotes healthy psychological function, helping to maintain a balanced and calm state of mind.
  • Normal Muscle Function (Including Heart) - Magnesium is essential for muscle contraction and relaxation, including heart muscle, thus contributing to normal muscle function throughout the body.
  • Maintenance of Bones & Teeth - Magnesium supports the maintenance of normal bones and teeth, ensuring that your skeletal system remains strong and resilient.
  • Protein Synthesis & Cell Division - Magnesium contributes to normal protein synthesis and also has a role in the process of cell division, supporting tissue growth and repair throughout the body.

By incorporating magnesium glycinate into your daily supplement regimen, you can experience the benefits of this highly bioavailable and gentle form of magnesium while simultaneously supporting the many crucial functions it serves in your body.

Frequently Asked Questions

What is magnesium glycinate?

Magnesium glycinate is a supplement made up of magnesium (a mineral) and glycine (an amino acid), two substances that are vital for good health. There is one molecule of magnesium attached to 2 molecules of glycine, hence it is commonly called magnesium bisglycinate (the proper term).

Magnesium is one of 21 essential minerals your body needs to function. It’s critical for bone health, energy production, muscle health and psychological function, to name just a few of its jobs. It’s also known as an electrolyte because of its important role in your body’s “electrical circuit”.

Glycine is an amino acid that your body uses to make proteins. These are used for building and repairing tissues, and for creating substances like hormones and enzymes. Glycine in particular plays a role in healthy joint function and digestion, and acts as an important neurotransmitter in your nervous system making it a key amino acid for brain health and function. It’s also commonly used as a natural sleep aid due to it's calming properties.

How much magnesium glycinate should I take?

The recommended magnesium dosage and intake changes depending on your age and sex. The table below shows the adequate intake (AI) and recommended dietary allowance (RDA) from the National Institute of Health.

Birth to 6 months30 mg*30 mg*
7–12 months75 mg*75 mg*
1–3 years80 mg80 mg

*Adequate Intake (AI)

What is non-buffered magnesium glycinate?

Non-buffered magnesium glycinate refers to a pure form of magnesium glycinate without any additional magnesium compounds. This pure form ensures maximum bioavailability and optimal benefits for the user.

It is very common practise for brands to use a buffered magnesium glycinate ingredient which has been diluted with magnesium oxide, so a large % of the elemental magnesium from this ingredient will come from the magnesium oxide.

What is magnesium glycinate chelate?

Magnesium glycinate chelate is another term for magnesium glycinate, highlighting the chelation process by which magnesium and glycine are chemically bonded together.

Magnesium glycinate vs magnesium bisglycinate - what's the difference?

Magnesium glycinate and bisglycinate are interchangeable terms referring to the same compound. Both names highlight the chelation of magnesium with two molecules of the amino acid glycine.

Magnesium glycinate vs citrate - what's the difference?

Magnesium glycinate is a chelated form of magnesium known for its high bioavailability and gentle effect on the digestive system. Magnesium citrate is a magnesium salt of citric acid that is easily absorbed and also known for it's high bioavailability but at high dosages may cause digestive discomfort in some individuals.

How long for magnesium glycinate to work?

The time it takes for magnesium glycinate to work may vary between individuals. However, some users may experience noticeable benefits within a few hours to a few days after taking the supplement.

Does magnesium glycinate help sleep?

Magnesium glycinate may indirectly support sleep, as the amino acid glycine is known for its calming properties. Magnesium itself also plays a role in normal nervous system function, which can contribute to relaxation and better sleep.

When to take magnesium glycinate?

It is generally recommended to take magnesium glycinate with a meal to enhance absorption. Some users prefer taking it in the evening due to its potential calming effects that may promote better sleep.

Does magnesium glycinate cause diarrhea?

Magnesium glycinate is less likely to cause diarrhea compared to other forms of magnesium supplements, as it is gentle on the digestive system and more easily absorbed by the body. However, individual reactions may vary, and high doses may still cause gastrointestinal discomfort.

Does magnesium glycinate have side effects?

We know that magnesium glycinate doesn’t cause the same gastrointestinal side effects as some other magnesium supplements, but are there any other side effects you should be aware of?

Magnesium glycinate is generally safe, but it may not be suitable for people with kidney disease or other renal problems. That’s because your kidneys may not be able to get rid of excess magnesium through your urine, so you may end up with hypermagnesemia (too much magnesium) if you take magnesium supplements.

Magnesium glycinate may also react with certain medications and change how they work in the body. The medications most commonly affected are antibiotics, heart medications, acid reflux medications, and bisphosphonates (for osteoporosis).

If you have a health condition or you’re taking medications, it’s best to check with your doctor first to make sure magnesium glycinate supplements are safe for you.
