Magnesium Citrate vs. Glycinate: Understanding the Differences

Published: Last updated:

Magnesium is a vital mineral that plays a crucial role in various bodily functions, including energy production, muscle contraction, and nerve function. It’s involved in over 300 enzymatic reactions in the body, making it essential for overall health and well-being. While magnesium can be obtained through diet, many people opt for supplements to ensure they meet their daily requirements. Among the various forms of magnesium supplements available, magnesium citrate and magnesium glycinate are two popular choices.To better understand the differences in benefits and uses of these supplements, exploring the topic of magnesium citrate vs glycinate can be incredibly helpful. Understanding the differences between these two forms can help individuals make informed decisions about which one best suits their needs.

Magnesium citrate

Magnesium citrate is a combination of magnesium and citric acid. It’s commonly used as a laxative to relieve constipation due to its ability to draw water into the intestines, thereby softening stools and promoting bowel movements. This form of magnesium is highly bioavailable, which means that the body can easily absorb it. As a result, it’s often recommended for individuals with magnesium deficiency or those looking to quickly replenish their magnesium levels. However, the rapid absorption of magnesium citrate can sometimes lead to gastrointestinal side effects, such as diarrhoea or abdominal discomfort, especially when taken in high doses.

Magnesium glycinate

Magnesium glycinate, also known as magnesium bisglycinate, is a chelated form of magnesium that’s bound to the amino acid glycine. This bond enhances the absorption of magnesium in the intestines and may reduce the likelihood of gastrointestinal side effects compared to other forms of magnesium, such as citrate. Additionally, glycine itself has calming properties, which may complement the relaxing effects of magnesium, making magnesium glycinate a popular choice for promoting relaxation and sleep. Additionally, people with sensitive stomachs or those who are prone to diarrhoea frequently prefer magnesium glycinate because it is less likely to cause digestive problems.

Absorption and bioavailability

While the body can effectively absorb both magnesium citrate and magnesium glycinate, there are differences in their bioavailability and absorption rates. Magnesium citrate typically has higher bioavailability compared to magnesium glycinate, meaning a larger percentage of the magnesium is absorbed into the bloodstream. This makes magnesium citrate a more efficient option for quickly raising magnesium levels in the body, especially for individuals with severe deficiencies. On the other hand, the chelated form of magnesium in glycinate enhances its absorption in the intestines, despite its slightly lower bioavailability compared to citrate. This results in a more sustained release of magnesium, which may be preferable for maintaining steady levels throughout the day.

Uses and benefits

Both magnesium citrate and magnesium glycinate offer numerous health benefits beyond their primary roles in supporting bowel regularity and relaxation, respectively. Magnesium citrate is commonly used as a short-term solution for constipation relief, as it works quickly to soften stools and stimulate bowel movements. It’s also used to support overall magnesium levels in the body, which are essential for energy production, muscle function, and nerve transmission. On the other hand, magnesium glycinate is often favoured for its calming effects, making it a popular choice for promoting relaxation, reducing stress, and improving sleep quality. Additionally, glycine, the amino acid component of magnesium glycinate, has its own benefits, including support for cognitive function and mood regulation.

Side effects and considerations

While magnesium supplements are generally safe for most people when taken as directed, there are some considerations to keep in mind. As mentioned earlier, magnesium citrate may cause gastrointestinal side effects, such as diarrhoea or abdominal cramping, particularly when taken in high doses. It’s important to start with a low dose and gradually increase it as tolerated to minimise these effects. On the other hand, magnesium glycinate is less likely to cause digestive issues, making it a suitable option for individuals with sensitive stomachs. However, some people may experience mild side effects, such as nausea or stomach upset, especially if they have an underlying gastrointestinal condition. As with any supplement, it’s advisable to consult with a healthcare professional before starting magnesium supplementation, especially if you have any pre-existing medical conditions or are taking medications.

Takeaway

Magnesium is an essential mineral that plays a critical role in numerous bodily functions, and supplementation can be beneficial for maintaining optimal health. Magnesium citrate and magnesium glycinate are two popular forms of magnesium supplements, each with its own unique characteristics and benefits. While magnesium citrate is known for its effectiveness in relieving constipation and quickly raising magnesium levels in the body, magnesium glycinate offers the advantage of enhanced absorption and a reduced likelihood of gastrointestinal side effects. Ultimately, the choice between magnesium citrate and magnesium glycinate depends on individual needs and preferences. By understanding the differences between these two forms of magnesium, individuals can make informed decisions to support their overall health and well-being.
