Maintaining optimal health requires proper nutrition and supplementation, with magnesium being vital for numerous bodily functions. However, meeting the recommended daily intake solely through diet can be challenging.
This is where magnesium supplements, such as Magnesium Glycinate and Citrate, come into play. In this article, we will explore the comprehensive comparison of Magnesium Glycinate vs. Citrate. Uncovering their benefits and their common uses.
Join us on this journey to uncover the potential of Magnesium Glycinate and citrate for enhancing your well-being.

How much Magnesium Does a Human need?
The recommended amount of magnesium may differ depending on one’s age, sex, and other conditions. For instance, young men need around 400mg of magnesium, while older men need 420mg daily. Meanwhile, young women need 310mg daily and 320mg for older ones.
Pregnant and breastfeeding need more, which can go around 350-360mg daily. Interestingly, children need a lesser amount of magnesium, but the amount they need does not differ despite their sex differences. The difference begins to exist upon reaching 14 years old. [1][2]
Magnesium Glycinate Vs. Citrate: Differences
Magnesium Glycinate and Magnesium Citrate are two of the most common forms of magnesium our body can absorb. These two mineral forms can be found in several sources, including dietary supplements. However, like many things, both come with their differences.
We can distinguish those differences through the following general key concepts:
- Bioavailability and origin
- Benefits and Uses
- Side effects
- Dosage
Magnesium Glycinate Vs. Citrate: Bioavailability and Origin
The first difference between Magnesium Glycinate and Citrate is noticeable through its bioavailability and origin. Bioavailability is the state of a substance in terms of digestion. Therefore, when we say that a substance is bioavailable, the body can absorb it easily.
Studies show that Magnesium Glycinate and Citrate are more bioavailable than their other forms. This is one of the reasons for its wide availability of dietary supplements. However, as for its origin, Glycinate is also found in Glycine-rich foods. [3]
Glycine is one of the amino acids that work well with regulating hormones. It is something that Magnesium Glycinate also influences in the body. Thus, many health benefits have been seen on it.
Meanwhile, Magnesium Citrate is a substance also present in laxatives. It is primarily composed of salt and some compounds of foods rich in citric acid. It has said to be commonly used for treating constipation. [4][5][6]
Magnesium Glycinate Vs. Citrate: Benefits

In general, magnesium positively affects our overall health. It lowers the risk of developing heart disease and stroke, type 2 diabetes, and bone fractures and reduces the likelihood of having headaches. It is also associated with better sleep and reduced muscle cramps.
However, the two come with differences in terms of sets of benefits. For instance, Magnesium Glycinate can help through the following conditions:
- Anxiety relief
- Reduction of depressive symptoms
- Bone health and strength
- Healthy blood sugar
- Premenstrual syndrome management
- Pain relief
- Migraine
On the other hand, Magnesium Citrate is known as a good aid for the following conditions:
- Constipation
- High blood pressure
- High blood sugar
- Anxiety
- Sleep Quality
- Bone’s health and strength
- Muscle strength
These differences sometimes make it hard to decide which form of magnesium they should take. For most studies, Glycinate is more effective in general well-being, while Citrate is more effective for calming the body. [7][8]
Magnesium Glycinate Vs. Citrate: Uses

As we can observe from the benefits of Magnesium Glycinate and Citrate, generally, both affect one’s health through similar aspects. This part will discuss more details about these common forms of magnesium.
Magnesium Glycinate Vs. Citrate for Sleep
Both Magnesium Glycinate and Citrate may affect sleep patterns or a person’s sleep quality. However, they differ in the ways they do such a thing. Nevertheless, magnesium generally affects neurotransmitters and the production of melatonin – a hormone associated with sleepiness.
According to a study among people with depression, Magnesium Glycinate helped improve their mood. Aside from that, it also improved in alleviating symptoms like anxiety, irritability, suicidal thoughts, ideations, and many more, just like the DHEA hormone.
The study results suggest that mood improvement can also contribute to better sleep. While it helps the regulation of melatonin, a more uplifted mood, reduction of stress, and anxiety relief lead to high-quality sleep. [9]
Meanwhile, Magnesium Citrate works better with constipation relief. As it works with your digestive system, the body can adjust and regulate other hormones that may affect other aspects of health.
This way, the body is least likely to be overwhelmed in fulfilling one’s needs, such as relaxation for sleep. In short, Citrate’s effect on sleep is less direct than Glycinate. [10]
Magnesium Glycinate vs. Citrate for Leg Cramps
According to research, both forms of magnesium may help reduce leg cramps. However, the evidence needs to be improved, and additional research is needed to verify its efficacy further.
Nevertheless, experts hypothesized that citrate is more effective than other forms of Magnesium. [11][12]
Magnesium Glycinate Vs. Citrate: Side Effects
Regarding side effects, both Magnesium Glycinate and Citrate perform well in the body. No negative impact will be visible if the person does not overdose. Otherwise, you may experience the following:
- Diarrhea
- Dizziness
- Low blood pressure
- Weakness
- Abnormal heartbeat
- Deterioration of kidney function
To avoid such side effects, consider only the recommended dose. Alternatively, consult your doctor first, especially if you are taking other medicines. Note that magnesium, regardless of any form, may have a negative drug interaction with other treatments. [13][14]
Magnesium Glycinate vs. Citrate: Dosage

In terms of dosage, there are not so many differences between the two forms. However, each product comes with dosage instructions. Typically, it is also something that you should follow. Alternatively, doctors can prescribe a more suitable dose for you.
Bottomline
Magnesium Glycinate and Magnesium Citrate are just two of the various forms of magnesium. While they have similarities, differences between them still exist.
For instance, Magnesium Glycinate stands out for its calming effects, promoting improvement in mood and sleep. On the other hand, Magnesium Citrate is better for treating constipation. Nevertheless, both can be beneficial to one’s health.
