Magnesium Malate vs Glycinate: Key Differences, and Which to Choose

Are you confused about which magnesium supplement might be best for your specific health needs? Magnesium is one of the most essential minerals in your body, involved in hundreds of biochemical reactions, yet many people don’t get enough through diet alone. Among the various forms available, magnesium malate and magnesium glycinate are two popular options, both offering distinct benefits.

Magnesium plays crucial roles in energy production, muscle function, nervous system regulation, and for maintaining healthy bones. When dietary intake falls short, supplements can help bridge the gap. However, not all magnesium supplements are created equal, and choosing between malate and glycinate depends on your specific health goals and individual needs.

Let’s explore the unique properties of these two forms of magnesium and how they might benefit different aspects of your health.

Understanding Magnesium

Magnesium is the fourth most abundant mineral in your body and is involved in over 300 enzymatic reactions. It supports proper muscle and nerve function, helps maintain healthy blood pressure, and contributes to bone development. Despite its importance, many people don’t consume adequate amounts through their diet.

Information from health authorities indicate that magnesium deficiency is a common problem which is linked to several health conditions. It may be useful to recognise the symptoms of low levels of magnesium to help you decide on the best regime of boosting levels either by wholefoods, supplementation, or possibly both.

Magnesium supplements come in various forms, each with unique properties and benefits. Eight main types are suitable as dietary supplements: citrate, glycinate, chloride, lactate, malate, sulphate, oxide, and taurate (a mixture of magnesium and the amino acid tourine).

The form of magnesium you choose can significantly impact how well your body absorbs it and what specific health benefits you might experience. Let’s examine the common types of magnesium supplements to better understand where malate and glycinate fit in the spectrum.

Magnesium Form	Bioavailability	Primary Benefits	Best For
Malate	High	Energy production, muscle function	Fatigue, muscle pain
Glycinate	High	Calm, sleep, minimal digestive impact	Sleep issues, anxiety, sensitive digestion
Citrate	Medium-High	General use, constipation relief	Digestive health, general supplementation
Oxide	Low	High elemental magnesium content	Constipation, heartburn
Taurate	Medium-High	Cardiovascular support	Heart health, blood pressure
Threonate	High	Cognitive function	Brain health, memory
Chloride	Medium	Digestive aid	Digestive issues
Sulphate	Low (topical)	Muscle relaxation	Topical application, baths

What is Magnesium Malate?

Magnesium malate is a compound formed by combining magnesium with malic acid. Malic acid is a natural substance found in many fruits, particularly apples, and plays a key role in the body’s energy production cycle. This combination creates a supplement that not only provides magnesium but also delivers the potential benefits of malic acid.

Magnesium malate is known for its high bioavailability, meaning your body can absorb and utilise it efficiently. The malic acid component helps transport magnesium into cells, potentially enhancing its effectiveness. This form of magnesium has a gentler effect on the digestive system compared to some other forms like oxide or sulphate.

This supplement is typically available in capsule, tablet, or powder form, giving you flexibility in how you take it. Many people find the taste less bitter than other magnesium forms, making it more palatable when taken as a powder mixed with water or other beverages.

For those interested in trying a high-quality magnesium malate supplement, Supplement Place offers magnesium malate formulated for optimal absorption and effectiveness.

Magnesium Malate Benefits

Magnesium malate offers several potential health benefits that make it a popular choice among various magnesium supplements.

Energy Production Support

One of the standout benefits of magnesium malate is its role in energy metabolism. Both magnesium and malic acid are involved in the body’s energy production cycle (Krebs cycle). This makes magnesium malate potentially beneficial for people experiencing fatigue or low energy levels.

Muscle Function and Recovery

Magnesium malate may help support healthy muscle function and recovery after exercise. A controlled study found that magnesium supplementation (392 mg elementary magnesium) showed a statistically significant maximal serum increase of 0.071 mmol/L (8.4%) compared to 0.041 mmol/L (4.8%) for placebo (p = 0.05), which may contribute to better muscle performance.

Digestive Comfort

Compared to some other forms of magnesium, malate tends to cause less digestive distress, making it suitable for people with sensitive stomachs who still need magnesium supplementation.

Potential Drawbacks of Magnesium Malate

While magnesium malate offers many benefits, it’s important to consider potential limitations:

• Stimulating Effects: Some people find that magnesium malate’s energy-supporting properties can be stimulating. If taken in the evening, this might affect sleep quality.
• Cost Considerations: Magnesium malate tends to be more expensive than some other forms of magnesium like oxide, though this is often justified by its higher absorption rate and additional benefits from malic acid.
• Individual Responses: As with any supplement, individual responses vary. What works well for one person may not provide the same benefits for another.

What is Magnesium Glycinate?

Magnesium glycinate (also called magnesium bisglycinate) is formed by combining magnesium with glycine, an amino acid that acts as a neurotransmitter with calming effects in the brain. This combination creates a highly absorbable form of magnesium that’s known for being gentle on the digestive system. The glycine component not only improves absorption but also contributes additional benefits, particularly for sleep and anxiety.

Magnesium glycinate is typically available in tablet, capsule, or powder form. It often has a milder taste than other magnesium forms, making it more palatable when taken as a powder. Its gentle action on the digestive system means it’s less likely to cause the laxative effect associated with some magnesium supplements.

Supplement Place offer Magnesium Bisglycinate in a highly bioavailable form with added benefits of glycine making the supplement gentle on the digestive system. Our magnesium bisglycinate is buffered and provides 20% elemental magnesium.

Key Benefits of Magnesium Glycinate

Magnesium glycinate offers several distinct advantages that make it a popular choice.

Sleep Support

The glycine component of magnesium glycinate has calming effects on the brain, which may help improve sleep quality. Many people take magnesium glycinate in the evening to help with relaxation and sleep.

Anxiety and Mood

Both magnesium and glycine have roles in supporting healthy nervous system function. This combination may help manage stress and anxiety.
Gentle on Digestion – Magnesium glycinate is less likely to cause digestive discomfort compared to other forms of magnesium. This makes it an excellent choice if you have a sensitive digestive system or have experienced gastrointestinal side effects with other magnesium supplements.

Women’s Health

Magnesium supplementation has shown promise for women’s health concerns. A study found that magnesium supplementation (400-800 mg of magnesium oxide) reduced hot flush scores by 50.4% in women on tamoxifen or aromatase inhibitors, with significant reductions in fatigue, sweating, and distress. While this study used magnesium oxide, the benefits might extend to other forms like glycinate.

Potential Drawbacks of Magnesium Glycinate

Despite its many benefits, magnesium glycinate has some potential limitations to consider:

• Higher Cost: Magnesium glycinate tends to be more expensive than some other forms of magnesium due to its specialised formulation and additional benefits.
• Less Energising: While its calming effects are beneficial for many, if you’re specifically looking for energy support you may prefer magnesium malate over glycinate.
• Limited Laxative Effect: If you’re seeking magnesium for its laxative properties, glycinate might not be as effective as citrate or oxide forms.
