The health benefits of magnesium are extensive. It can help ward off conditions associated with magnesium deficiency such as cramping, chronic fatigue, and irritability. Adequate magnesium intake has been associated with a lower risk of atherosclerosis and hypertension. It may also lower the risk of developing type 2 diabetes by improving insulin sensitivity. It also plays a role in the treatment and prevention of osteoporosis, and migraine headaches, and can alleviate PMS symptoms. Magnesium is also known for its calming effects on the nervous system. This is why it is a popular supplement for those seeking to reduce stress, anxiety, and depression, and improve sleep.
Magnesium-rich dietary sources include whole grains, nuts, seeds, legumes (especially black beans), green leafy vegetables, chocolate, and fortified foods. However, many people may not get the sufficient nutritional needs of magnesium from their diet alone. This is due to factors such as soil depletion, processed food diets, and digestive disorders that impair absorption.
Forms of Magnesium Supplements
This is where supplements come in. Magnesium is available in various forms, each with its own set of advantages, bioavailability, and specific uses. Understanding the differences can help you choose the best form for your needs. Here are some common types of magnesium supplements:
Magnesium Glycinate: Known for its high bioavailability and gentle effect on the stomach. Magnesium glycinate is a chelated form of magnesium, meaning it is attached to the amino acid glycine. This form is often recommended for individuals who need to correct a deficiency without the uncomfortable feeling caused by laxative effects. It’s also praised for its potential to promote relaxation and support sleep.
Magnesium Citrate: This form is magnesium combined with citric acid. While it has a good bioavailability, it’s also known for its laxative properties. It is frequently used to treat constipation or prepare for certain medical procedures. It’s a middle-of-the-road option regarding the balance between absorption and gentle effects on the bowels.

Magnesium Oxide: Often found in milk of magnesia, this form of magnesium is typically used for its laxative properties. It has a lower bioavailability compared to other forms. But it can be useful in treating upset stomachs, acid reflux, and heartburn, as well as for short-term relief of constipation.
Magnesium Chloride: With a good absorption rate, it can be found in both pill form and as a topical solution. It is sometimes used for its potential benefits in kidney function. It may be easier on the digestive tract than magnesium oxide.
Magnesium L-Threonate: This newer form is suggested to be particularly effective for cognitive health. Mainly because it may enhance magnesium uptake in brain cells. It’s an option for those looking to improve memory and brain function.
Magnesium Glycinate vs Citra
Magnesium is a versatile mineral with various formulations, each boasting distinctive features and health benefits. However, when it comes to supplementation, two particular forms stand out: magnesium glycinate and magnesium citrate. If you’re contemplating adding a magnesium supplement to your regimen, understanding the differences between these two options is critical for making an informed decision. That’s why comparing magnesium glycinate vs citrate becomes an essential step in selecting the supplement that aligns best with your health objectives.
Magnesium Glycinate

Magnesium glycinate is a form of magnesium supplement where the elemental magnesium is bound to the amino acid glycine. This chelated form, where magnesium is coupled with a carrier, helps to increase its bioavailability and absorption. Especially when compared to some other forms of magnesium supplements.
When ingested, magnesium glycinate is easily absorbed in the intestines due to the presence of glycine. It facilitates its transport through the intestinal wall. This improved absorption is because the body recognizes this chelated compound more like a food rather than a simple mineral salt. They often encounters absorption competition or interference.
Magnesium glycinate benefits:
Enhanced Absorption: As previously mentioned. The chelated form with glycine improves the uptake of magnesium compared to other forms like magnesium oxide or sulfate.
Gentle on the Stomach: Unlike some other magnesium compounds. Magnesium glycinate is less likely to cause digestive discomfort or laxative effects. This mak it suitable for individuals with sensitive digestion or those who are at risk of magnesium-induced diarrhea.
Supports Mental Calmness and Sleep: The glycine component is known for its calming effects on the brain. It could potentially enhance the natural calming effects of magnesium, which may improve sleep quality and support mood regulation.
Muscle Health: Magnesium glycinate is often recommended for individuals experiencing muscle cramps or spasms. It may help relieve muscle discomfort.
Despite its benefits, magnesium glycinate does have some drawbacks:
Cost: It is typically more expensive than other forms of magnesium, such as magnesium oxide or citrate. This could be a consideration for someone taking a magnesium supplement regularly.
Less Laxative Effect: For individuals specifically looking for magnesium to aid with constipation. The gentle nature of magnesium glycinate may not provide the desired laxative effect that other forms like magnesium citrate do.
Limited Research: While there are many anecdotal reports and theoretical benefits of magnesium glycinate. There’s less research on this particular form compared to others like magnesium citrate or chloride regarding certain health outcomes.
Magnesium Citrate

Magnesium citrate is a combination of magnesium and citric acid. This form of magnesium is commonly used for its laxative effect and to treat conditions like constipation. It’s also known for its relatively good bioavailability compared to other forms of magnesium, which means the body can absorb it more easily. Over-the-counter, it’s available in powder, liquid, and pill forms.
When you take magnesium citrate, it is absorbed in the small intestine through a process called passive diffusion. As it is already in an ionic state, it doesn’t require stomach acid for its dissolution, which allows it to have a relatively high bioavailability.
Magnesium citrate benefits:
Laxative Effects: Because magnesium citrate attracts water through osmosis when in the intestine, it can increase stool water content, making it a useful remedy for relieving constipation and cleansing the bowel before medical procedures.
Bioavailability: Magnesium citrate has higher bioavailability compared to other forms of magnesium, meaning more of it is utilized by the body.
Relaxation and Sleep: Magnesium plays a role in the relaxation of muscles and the nervous system, which may aid in improving sleep quality and reducing anxiety.
Cardiovascular Health: Adequate magnesium intake has been linked to a lower risk of hypertension, heart disease, and stroke.
Despite its benefits, magnesium citrate does have some drawbacks:
Gastrointestinal Issues: The same laxative quality that is a benefit can become a drawback if it leads to diarrhea or dehydration when taken in high doses.
Drug Interactions: Magnesium citrate can interact with certain medications, such as diuretics, antibiotics, and bisphosphonates, and may affect their absorption or efficacy.
Dosage Control: Due to its laxative effect, it can be challenging for some people to find the right dosage that provides enough magnesium without causing loose stools.
