Magnesium is an essential mineral that supports everything from muscle function to sleep quality, but with so many supplement options, it can be tough to know which one to choose.

If you're trying to decide between magnesium glycinate vs citrate, you've come to the right place. In this article, we'll break down the key differences between these two popular forms, including their benefits, absorption rates, and who they're best suited for.

Glycinate, otherwise known as magnesium bisglycinate is often chosen for its calming effects and gentle impact on digestion, while magnesium citrate is known for its role in supporting digestion and relieving constipation.

So, if you're ready to learn which one fits your health needs best, keep reading as we explore everything you need to know about magnesium glycinate vs citrate.

What this article covers:

Understanding Magnesium Supplements

Magnesium is an essential mineral that supports over 300 biochemical reactions in the body, including muscle function, nerve health, energy production, and bone strength.

Despite its importance, many people don't get enough magnesium from food alone due to soil depletion, poor dietary choices, or medical conditions that affect absorption.

This is where supplementation becomes essential. With various forms available—each offering different benefits and absorption rates—it's important to understand how they work before choosing the right one.

Some forms, like magnesium glycinate, are better for relaxation and sleep, while others, like magnesium citrate, support digestion and regularity.

Knowing the differences can help you select the best option for your specific health needs.

The Importance of Magnesium in the Body

Magnesium is essential for muscle contractions, nerve signalling, and maintaining steady energy levels throughout the day.

It plays a critical role in bone density, helping to prevent conditions like osteoporosis. This mineral also regulates blood sugar levels, supports cardiovascular health by maintaining normal blood pressure, and aids in the production of proteins and DNA.

Many Canadians may be deficient due to low dietary intake, chronic stress, or medications that deplete magnesium levels, such as diuretics and proton pump inhibitors.

Deficiency can lead to muscle cramps, fatigue, irritability, and even irregular heart rhythms, making supplementation an important consideration for overall health.


Common Forms of Magnesium Supplements

Not all magnesium supplements are the same. Each form has different absorption rates and health benefits, making it important to choose the right one based on your needs. Here are the most common types:

  • Magnesium – A general term for magnesium supplements that support overall health, including muscle function, nerve signalling, and bone strength.
  • Magnesium glycinate – Highly bioavailable and gentle on the stomach, making it ideal for those looking to support relaxation, stress management, and sleep.
  • Magnesium citrate – Well-absorbed and often used for digestive support due to its natural laxative effect, making it a common choice for those struggling with constipation.
  • Magnesium threonate – Known for its ability to cross the blood-brain barrier, this form is linked to cognitive function and memory support.

Magnesium Glycinate

Composition and Absorption

Magnesium glycinate is a combination of magnesium and glycine, an amino acid that helps improve absorption. It's highly bioavailable, meaning your body absorbs it efficiently.

Specific Benefits

  • Promotes relaxation and better sleep – Magnesium glycinate binds to glycine, an amino acid known for its calming effects on the nervous system. This makes it an excellent choice for those struggling with insomnia or restless sleep.
  • Supports muscle and nerve function – This form of magnesium helps regulate nerve impulses and muscle contractions, reducing muscle cramps, spasms, and overall tension.
  • Gentle on the stomach – Unlike some other forms of magnesium, glycinate does not have a laxative effect, making it a good option for those with sensitive digestion or prone to gastrointestinal discomfort.
  • May help with anxiety and stress management – Magnesium plays a key role in neurotransmitter function and may help regulate the body's stress response, potentially reducing symptoms of anxiety and promoting overall relaxation.

Potential Side Effects

  • Diarrhoea at high doses – While magnesium glycinate is generally well-tolerated, taking excessive amounts may cause diarrhoea. However, this is less common compared to other forms like magnesium citrate, which has a stronger laxative effect.
  • Mild nausea on an empty stomach – Some people may experience mild nausea if they take magnesium glycinate without food. To avoid this, it's best to take it with a meal or snack.
  • Potential interactions with medications – Magnesium can interfere with the absorption of certain medications, including antibiotics and osteoporosis treatments. If you take prescription medications, consult a healthcare provider before supplementing.
  • Possible drowsiness in some individuals – Since magnesium glycinate supports relaxation, some people may feel slightly drowsy after taking it. This makes it a great option for evening use but may not be ideal before activities requiring alertness.

magnesium citrate vs glycinate

Magnesium Citrate

Composition and Absorption

Magnesium citrate is a combination of magnesium and citric acid. It's highly absorbable and has a mild laxative effect, making it popular for digestive health.

Specific Benefits

  • Helps with constipation and promotes regular bowel movements – Magnesium citrate has a natural laxative effect, drawing water into the intestines to soften stool and support regularity. It is commonly used for occasional constipation relief and is often recommended for short-term digestive support.
  • Supports muscle relaxation and may reduce cramps – Magnesium plays a key role in muscle function, helping to prevent cramps, spasms, and tension. Magnesium citrate may benefit those who experience muscle tightness or occasional discomfort after exercise.
  • Aids in hydration and electrolyte balance – Magnesium works alongside potassium and sodium to maintain proper fluid balance in the body. Magnesium citrate can support hydration, especially for individuals who sweat excessively or engage in high-intensity activities.
  • Often used for occasional digestive relief – Due to its ability to stimulate bowel movements, magnesium citrate is sometimes used before medical procedures like colonoscopies. It can also help ease bloating and mild digestive discomfort.

Potential Side Effects

  • Can cause loose stools or diarrhoea if taken in high doses – Magnesium citrate attracts water into the intestines, which can lead to loose stools or diarrhoea if too much is consumed. This effect is more pronounced in individuals with sensitive digestion.
  • Some people may find it too harsh on the digestive system – While magnesium citrate is effective for relieving constipation, some may experience bloating, cramping, or stomach discomfort, especially when taken in high doses or on an empty stomach.
  • Not ideal for long-term use if taken for laxative purposes – Regular use of magnesium citrate as a laxative may lead to dependency, where the body becomes reliant on it for bowel movements. It should only be used occasionally or under the guidance of a healthcare professional.

Key Differences Between Magnesium Glycinate and Magnesium Citrate

Bioavailability and Absorption Rates

Both forms are well-absorbed, but magnesium glycinate tends to be better tolerated by those with sensitive stomachs. Magnesium citrate absorbs quickly but may cause digestive upset in some people.

Targeted Health Benefits

  • Glycinate is best for relaxation, sleep, and overall nervous system support.
  • Citrate is ideal for digestive health and occasional relief from constipation.

Suitability for Different Individuals

  • If you struggle with stress, anxiety, or sleep, magnesium glycinate is the better choice.
  • If you're dealing with constipation or need a quick magnesium boost, magnesium citrate may be more effective.
