What Is Magnesium Glycinate

Magnesium glycinate is a dietary supplement that combines magnesium, an essential mineral, with the amino acid glycine. This compound offers several health benefits due to its high bioavailability, meaning it is easily absorbed by the body. In this section, we will discuss the source of magnesium and the role of the amino acid glycine in the formation of magnesium glycinate.

Source of Magnesium

Magnesium is a crucial mineral for a variety of bodily functions, including maintaining proper nerve function, muscle health, and bone strength. It is naturally found in many foods, such as leafy greens, nuts, and whole grains. However, certain individuals may require additional supplementation through magnesium glycinate to achieve optimal magnesium levels, particularly those with magnesium deficiency or difficulty absorbing minerals from food. Magnesium glycinate is preferred over other forms of magnesium supplements, such as magnesium oxide, for its superior absorption rate and reduced side effects. ¹

Amino Acid Glycine

Glycine is a non-essential amino acid, which means the body can produce it on its own, but it can also be obtained through diet. It plays a vital role in protein synthesis and overall metabolic function. When combined with magnesium, the resulting compound, magnesium glycinate, delivers the health benefits of magnesium with a reduced risk of side effects often associated with other forms of magnesium supplements. The presence of glycine enhances magnesium's bioavailability, allowing for better absorption and increased effectiveness in addressing magnesium deficiencies. ²

Benefits and Functions

Bone Health

Magnesium glycinate plays an essential role in maintaining bone health. It helps activate vitamin D, which aids in the balance between calcium and phosphate for bone growth and maintenance. Adequate magnesium intake also supports strong bones and prevents osteoporosis.

Heart Health

Magnesium glycinate contributes to heart health by supporting muscle and nerve function. Low magnesium levels can increase the risk of high blood pressure and heart disease. Furthermore, magnesium assists in maintaining a healthy cardiovascular system by reducing blood pressure and preventing complications such as heart attacks and strokes.

Mood and Sleep

Magnesium glycinate has several benefits related to mood and sleep. It has been shown to relieve anxiety and promote a sense of calmness. Additionally, magnesium plays a vital role in energy production, which can help combat feelings of fatigue and depression. Magnesium glycinate is also known for improving sleep quality by supporting the production of melatonin, a hormone that regulates sleep-wake cycles.

Diabetes Management

Magnesium glycinate plays a role in diabetes management, particularly type 2 diabetes. Consuming high amounts of magnesium in the diet may reduce the risk of developing diabetes. Magnesium helps to break down sugars and might decrease insulin resistance, thereby contributing to better blood sugar control.

Magnesium Deficiency

Symptoms

Magnesium deficiency, also known as hypomagnesemia, can manifest with a variety of symptoms. Some early warning signs of low magnesium levels include fatigue, muscle weakness, cramping, and numbness or tingling sensations. In more severe cases, individuals may experience irregular heartbeat, muscle spasms, seizures, or even behavioral changes such as increased irritability and anxiety1.

Causes

Several factors can contribute to magnesium deficiency in both adults and children. Insufficient intake of magnesium-rich foods, such as leafy green vegetables, whole grains, and nuts, can lead to inadequate levels of this essential mineral2. Other factors that may cause hypomagnesemia include malabsorption issues, such as celiac disease, which can inhibit the body's ability to absorb magnesium from the diet3. On top of that, certain medications, excessive alcohol consumption, and chronic illnesses, such as diabetes, can also lead to low magnesium levels4.

Diagnosis

A doctor can diagnose magnesium deficiency by evaluating the patient's symptoms, medical history, and conducting a blood test to check for low magnesium levels. The test usually measures the amount of magnesium circulating in the blood, with normal ranges typically falling between 1.7 and 2.2 milligrams per deciliter (mg/dL)5. If the blood test results indicate hypomagnesemia, additional tests may be performed to identify and address the underlying cause.

Magnesium Glycinate Supplements

Forms and Dosages

Magnesium glycinate supplements come in various forms, including pills, powder, and capsules. To ensure you are getting the correct dosage, it is essential to follow the manufacturer's guidelines or seek advice from a healthcare professional. Dosage guidelines may differ depending on your age, overall health, and nutritional needs.

Typically, magnesium glycinate supplements are available in these forms:

• Capsules: Usually containing 100-200mg of elemental magnesium per capsule.

• Powder: Generally providing 200-400mg of elemental magnesium per serving, which can be mixed with water or juice.

• Pills: Containing different strengths, ranging from 100-500mg of elemental magnesium per pill.

Bioavailability

An essential aspect to consider when choosing a magnesium supplement is its bioavailability. In other words, how easily the body can absorb and utilize the magnesium. Magnesium glycinate, deemed highly bioavailable, is formed by combining elemental magnesium with the amino acid glycine. This form is easily absorbed in the body, making it an effective choice for those looking to increase their magnesium levels.

Because of its high bioavailability, magnesium glycinate supplements may provide several benefits, such as improving sleep quality, reducing muscle cramps, and supporting overall cardiovascular health. It is crucial to choose a supplement that has a high absorption rate in order to get the best possible results from your magnesium intake.

Side Effects and Interactions

Common Side Effects

Magnesium glycinate is generally well-tolerated, but some people may experience side effects. Common side effects of magnesium glycinate may include nausea, vomiting, diarrhea, and stomach upset. However, magnesium glycinate is less likely to cause these side effects compared to other forms of magnesium supplements due to its enhanced absorption and gentler effect on the digestive system.
