Recent research suggests a significant correlation between magnesium intake and the prevention and management of Type 2 diabetes. Many studies agree that adequate levels of magnesium in the body can potentially improve insulin action, subsequently contributing to better blood sugar control.

Can Low Magnesium Cause Type 2 Diabetes?

Chronic low levels of magnesium, a state known as hypomagnesemia, might heighten the risk of developing Type 2 diabetes. A study published in 2013 found that dietary intake of magnesium decreases the risk of Type 2 diabetes by improving glucose metabolism and insulin resistance.

Another research showed that for every 100 milligrams per day increase in magnesium intake, there was a 15 percent decrease in the risk of developing Type 2 diabetes. However, it is important to underline that while low magnesium can be an associated risk factor, Type 2 diabetes is a multifactorial disease. It is influenced by a range of elements including genetic predisposition, unhealthy lifestyle, and obesity.

Why Do Type 2 Diabetics Have Low Magnesium?

Type 2 diabetics often have lower magnesium levels compared to individuals who are non-diabetic. The reason behind this lies in the very nature of diabetes itself. High blood sugar levels, common in people with diabetes, lead to frequent urination, which can result in increased loss of magnesium through the urine. This condition, known as diabetic hyperglycemia, along with a diet deficient in magnesium, contributes to insufficient magnesium levels in the body.

In addition, some diabetic medications have been reported to decrease magnesium levels. Therefore, maintaining optimal magnesium levels through diet or supplementation can be a critical aspect of managing Type 2 diabetes.

What Type of Magnesium is Best for Type 2 Diabetes?

Given the wide variety of magnesium forms available on the market, it can be a daunting task to choose the most suitable one. However, not all forms of magnesium are created equal. Each has a unique absorption rate and therapeutic value, with some being more bioavailable and effective than others, particularly for managing Type 2 diabetes.

What Kind of Magnesium is Good for Diabetes?

When it comes to managing Type 2 diabetes effectively, the choice of the best magnesium supplement can play a crucial role. Among the many forms of magnesium available, a few stand out due to their higher bioavailability and efficacy in improving insulin action and glucose metabolism.

Chelated forms of magnesium have high bioavailability and are effectively absorbed in the body. These forms are bonded to another molecule (usually an amino acid) to enhance absorption — such as magnesium aspartate, magnesium citrate, magnesium lactate, and magnesium chloride. These are beneficial for people with diabetes as they can help improve insulin function and glucose metabolism.

Here’s a closer look at each of these types:

Magnesium Aspartate

Magnesium Aspartate is one of the most bioavailable forms of magnesium, with a high absorption rate. It combines magnesium with aspartic acid, an amino acid naturally found in protein-rich foods. This form is often used in supplements and is recognized for its ability to enhance energy levels and reduce fatigue, apart from its potential benefits to Type 2 diabetes management.

Magnesium Citrate

Considered one of the best magnesium supplements for Type 2 diabetes, Magnesium Citrate is another highly bioavailable form of magnesium. It is a combination of magnesium and citric acid, and it has a high absorption rate. It’s often recommended to improve glycemic control and insulin sensitivity in diabetics. Additionally, it is also known for its laxative properties and effectiveness in treating constipation.

Magnesium Lactate

Magnesium Lactate, the magnesium salt of lactic acid, is another form found in several dietary supplements. Its absorption rate is relatively high, and it’s less likely to cause digestive disturbances, making it suitable for individuals with sensitive stomachs. It has been associated with reducing insulin resistance and improving blood glucose control, thereby playing a significant role in managing Type 2 diabetes.

Magnesium Chloride

Lastly, Magnesium Chloride is a form known for its high solubility and bioavailability. It is obtained from the brine or sea water and is often used in topical products like bath salts and lotions, besides oral supplements. It has various health benefits, including improving digestion, bone health, and mental health, along with the potential to improve insulin sensitivity in Type 2 diabetics.

All the magnesium forms listed above are commonly found in various dietary supplements. However, it’s important to note that the effectiveness of these supplements can vary from one individual to another, based on factors like age, overall health, and the presence of any medical conditions. Always seek professional medical advice before starting a new supplement regimen.

Nonetheless, magnesium oxide, despite its low bioavailability, is also commonly recommended due to its high magnesium content per dose. Always remember, the choice of magnesium supplement should be based on individual health needs and after consultation with a healthcare professional.

What is the Most Effective Type of Magnesium for Diabetes?

Among the various forms, magnesium citrate is often considered one of the best magnesium supplements for Type 2 diabetes. Known for its high absorption rate and bioavailability, magnesium citrate can contribute significantly to improving insulin sensitivity and glucose control.

A study found a significant increase in insulin sensitivity in participants after taking 300 mg of magnesium citrate for 12 weeks. However, further research is required to solidify these findings.

Does Magnesium Glycinate Lower Blood Sugar?

Another form known for its effectiveness in managing Type 2 diabetes is magnesium glycinate. Considered one of the most bioavailable forms of magnesium, magnesium glycinate has been shown to improve insulin sensitivity and glycemic control.

Daily supplementation with magnesium glycinate led to significant reductions in fasting plasma glucose and improvements in the glycemic status of people with Type 2 diabetes. Magnesium glycinate may also offer better tolerance for those with sensitive digestive systems due to its gentleness on the stomach.

In conclusion, both magnesium citrate and magnesium glycinate are potent forms of magnesium that can be utilized in the management of Type 2 diabetes. However, keep in mind that individual responses to supplements may vary, and thus, it is always best to consult with a healthcare provider before starting any supplementation regimen.

How Much Magnesium Should a Type 2 Diabetic Take?

Discovering the best magnesium supplement for type 2 diabetes is more than just about finding the right form. It’s about determining the appropriate dosage as well. Dosage requirements can be influenced by several factors, such as age, sex, and overall health status, and understanding these influences can help ensure optimal benefits from magnesium supplementation for managing Type 2 diabetes.

However, the American Diabetes Association states that additional doses may be beneficial for those with diabetes, subject to approval from a healthcare provider. Clinical studies often use doses ranging from 250 mg to 350 mg per day. It’s important to note that taking too much magnesium can lead to side effects, including diarrhea, nausea, and abdominal cramping.


Age is a significant factor when it comes to magnesium dosage. As per the National Institutes of Health, the recommended dietary allowance (RDA) of magnesium varies based on age.

For example, children between 1-3 years require 80 mg per day, 4-8 years require 130mg, 9-13 years require 240mg, and individuals aged 14 and above require up to 420 mg for men and up to 360 mg for women. But remember, these are general recommendations and might need to be adjusted for people living with Type 2 diabetes.


Sex also influences the magnesium requirement. As mentioned above, the recommended doses are different for men and women. However, during pregnancy, women might require a higher dosage. Furthermore, in the context of Type 2 diabetes, men and women might both require higher than the typical RDA, subject to the approval of a healthcare professional.

Overall Health Status

A person’s overall health status plays a notable role in determining the optimal dosage. For instance, people with Type 2 diabetes often experience magnesium deficiency due to increased magnesium loss through urination. Therefore, they might require a higher dosage of magnesium compared to non-diabetics. However, individuals with kidney disease should avoid high doses of magnesium. The kidneys regulate magnesium in the body, and compromised kidney function can lead to magnesium accumulation, resulting in potentially serious side effects.

Type of Magnesium Supplement

The type of magnesium supplement can also affect the dosage. Different forms of magnesium have varying levels of elemental magnesium, which is the actual amount of magnesium in the supplement. Hence, the dosage might vary depending on whether you’re taking magnesium citrate, glycinate, or any other form.

In conclusion, finding the best dosage of the best magnesium supplement for type 2 diabetes is not a one-size-fits-all proposition. It requires an individualized approach, considering various factors like age, sex, overall health status, and the type of supplement. It is always best to consult with a healthcare provider who can tailor a dosage regimen based on your specific health needs.

When is the Best Time to Take Magnesium for Diabetes?

There’s no definitive answer to this question as the best time to take magnesium may vary based on individual factors and the type of magnesium supplement used. Some people may prefer to take it with a meal to minimize potential side effects like stomach upset, while others may find it more beneficial to take it before bed, as some forms of magnesium can have a calming effect aiding in better sleep.

Can I Take Magnesium With Metformin?

Metformin is a commonly prescribed medication for Type 2 diabetes known to affect magnesium levels in the body. Some studies suggest that metformin can lower serum magnesium levels, making the use of magnesium supplements potentially beneficial for those on this medication. However, the study is not directly about metformin but the diarrheic effect of the drug resulting in decreased magnesium.

However, it’s crucial to consult with a healthcare provider before starting magnesium supplementation alongside metformin. They can provide guidance based on your individual health situation, ensuring safe and effective management of your Type 2 diabetes.

How Does Magnesium Interact With Other Nutrients?

When dealing with Type 2 diabetes, it’s essential to understand that the body functions as an interconnected system where nutrients often influence each other’s effectiveness. Therefore, even when using the best magnesium supplement for Type 2 diabetes, it’s crucial to consider its interaction with other vital nutrients – particularly calcium and vitamin D.

Magnesium and Calcium

Magnesium and calcium have a complex relationship. They are both essential minerals that play vital roles in the body, with calcium being crucial for bone health and nerve function, and magnesium playing a key role in energy metabolism and maintaining heart health.

However, balancing magnesium and calcium is crucial because high levels of calcium can interfere with the absorption of magnesium. Optimal calcium to magnesium ratio is widely believed to be 1.7-2.6 (weight to weight).

If there’s too much calcium and not enough magnesium, it can potentially lead to calcium overload and a relative state of magnesium deficiency, which might negatively influence glucose metabolism. Consulting with a healthcare provider can help ensure the right balance is met when supplementing.

Magnesium and Vitamin D

Magnesium’s relationship with vitamin D is another important interaction. Magnesium is crucial for the conversion of vitamin D into its active form. Without an adequate amount of magnesium, supplementation with vitamin D may not be effective.

Moreover, research published recently suggests that vitamin D supplementation can lead to a decrease in magnesium levels. For this reason, individuals taking vitamin D supplements may also need to take magnesium to ensure optimal vitamin D levels in the body.

By understanding these interactions and ensuring a balanced intake of magnesium, calcium, and vitamin D, you can effectively leverage the usefulness of the best magnesium supplement for Type 2 diabetes and contribute to the overall well-being and management of this condition.

As always, it’s advisable to consult with a healthcare provider before beginning any supplementation regimen, as they can provide personalized advice based on your unique health needs.

Who Should Not Take Magnesium?

While magnesium can be beneficial for many, it’s not suitable for everyone. Individuals with certain medical conditions should avoid taking magnesium supplements unless advised by a healthcare provider. In a study, however, it was found that higher magnesium levels in the blood is protective for individuals with chronic kidney disease opposing previous results. Nonetheless, this needs further investigation and research.

Moreover, certain medications can interact negatively with magnesium. These include diuretics, antibiotics, and medications used to treat osteoporosis. Therefore, individuals on these medications should consult with a healthcare provider before starting magnesium supplementation.

For most people, getting magnesium from food — such as green leafy vegetables, nuts, seeds, and whole grains — should be sufficient and is considered a safer option than supplementation. It’s always best to prioritize getting nutrients from a balanced diet rather than supplements unless specifically advised by a healthcare provider.


The significance of magnesium in the prevention and management of Type 2 diabetes is becoming constantly more apparent through ongoing research. A strong association is observed between adequate levels of magnesium and improved insulin action, glucose control, and reduced risk of developing the disease. However, many people with Type 2 diabetes often suffer from low magnesium levels due to increased excretion through urine, making the use of magnesium supplements a potential solution to consider.

Choosing the best magnesium supplement for Type 2 diabetes requires understanding the different forms of magnesium and their bioavailability. Forms such as magnesium citrate and magnesium glycinate are recognized for their absorption efficiency and positive effects on glycemic control.

The right dosage of magnesium is equally essential in managing Type 2 diabetes. Although there are general recommendations, consulting a healthcare provider can ensure an individual approach to dosage based on personal health conditions. Furthermore, while magnesium supplements can be valuable, some individuals should avoid them due to certain health conditions or medication interactions.

In essence, managing Type 2 diabetes can be a multifaceted approach combining a healthy lifestyle, balanced diet, regular exercise, proper medication, and possibly the addition of the right magnesium supplement. However, the information provided here should serve as a guide and not a replacement for professional medical advice. Always consult with a healthcare provider before beginning any supplementation regimen.

Stay informed, stay healthy, and manage Type 2 diabetes effectively by embracing the right strategies and choices. Together, let’s strive for a healthier tomorrow.
