Key Takeaways
- Magnesium malate combines magnesium with malic acid, a compound involved in cellular energy production. It's commonly chosen to support normal energy metabolism and normal muscle function.
- Magnesium glycinate pairs magnesium with glycine, an amino acid involved in neurotransmission. It's a popular choice for supporting relaxation and sleep quality.
- Both forms provide essential magnesium, but research hasn't established that one is universally better absorbed or more effective. Your nutritional needs and wellness goals can help guide your choice.
Magnesium is an essential mineral involved in hundreds of enzymatic reactions, including those responsible for energy production, muscle function, nerve signaling, and bone health. Although you can get magnesium from foods such as leafy greens, nuts, and seeds, supplements offer another way to meet your daily nutritional needs.
With so many magnesium formulations available, choosing the right one can feel complicated. Two popular options are magnesium malate and magnesium glycinate, each pairing magnesium with a different compound.
In this guide, we'll compare magnesium malate vs. glycinate, explore their potential benefits, and explain what to consider when choosing between them.
What Is the Difference Between Magnesium Malate and Glycinate?
The primary difference between these supplements is the compound bonded to the magnesium. Magnesium malate combines magnesium with malic acid, while magnesium glycinate combines magnesium with glycine.

Both forms supply magnesium, which supports normal muscle and nerve function, energy metabolism, and electrolyte balance. Neither is inherently better for everyone, and direct research comparing their absorption and effectiveness remains limited.
What Is Magnesium Malate?
Magnesium malate is a compound formed by combining magnesium with malic acid, an organic substance found naturally in foods such as apples. Malic acid plays a role in the Krebs cycle, a series of reactions that help cells produce adenosine triphosphate (ATP), the body's primary energy source.
Magnesium also supports enzymes involved in energy metabolism, making it an important mineral for normal cellular function.
What Are the Potential Benefits of Magnesium Malate?
Magnesium malate is commonly chosen by people interested in supporting energy metabolism and muscle function.
- Energy metabolism: Magnesium supports ATP-related enzymatic processes, while malic acid participates in the Krebs cycle. Both contribute to normal cellular energy production.
- Muscle function: Magnesium supports normal muscle contraction, relaxation, and nerve signaling.
- Daily wellness: Maintaining adequate magnesium intake helps support electrolyte balance and normal physical function.
Although these biological roles are well established, there isn't sufficient clinical evidence to show that magnesium malate provides more energy or improves physical performance better than other magnesium forms.
What Is Magnesium Glycinate?
Magnesium glycinate, also known as magnesium bisglycinate, is a chelated form of magnesium that is bonded to glycine, a nonessential amino acid. Glycine contributes to protein synthesis, neurotransmission, and several metabolic processes.
Magnesium glycinate is a popular supplement because of its association with relaxation and sleep support, as well as its reputation for being gentle on the digestive system.
What Are the Potential Benefits of Magnesium Glycinate?
Magnesium glycinate provides magnesium, which contributes to several essential bodily functions.
- Relaxation: Magnesium supports normal nerve signaling and muscle function, while glycine supports neurotransmission. Magnesium glycinate is commonly used to support relaxation and emotional wellness.
- Sleep quality: Some research suggests magnesium supplementation may support certain aspects of sleep quality, although findings are mixed and more research is needed.
- Muscle and nerve function: Magnesium helps maintain normal muscle contraction, nerve signaling, and electrolyte balance.
Magnesium Malate vs. Glycinate: How Absorption May Differ.
Bioavailability refers to how much of a nutrient the body absorbs and can use. Magnesium absorption varies by formulation, dosage, dietary intake, and individual factors.
Organic magnesium supplements generally demonstrated better bioavailability than inorganic forms. However, the studies varied in methodology, and the findings don't establish that magnesium malate is better absorbed than magnesium glycinate or vice versa.
Both are organic magnesium compounds, and current research doesn't provide enough direct comparisons to confidently rank them.
Which Magnesium Should You Take?
Choosing between magnesium malate and glycinate largely depends on your nutritional needs, preferences, and tolerance.
When Should You Consider Magnesium Malate?
Magnesium malate may appeal to those interested in supporting cellular energy metabolism and normal muscle function. Its combination of magnesium and malic acid is relevant to the body's energy-producing processes.
Although it's often taken in the morning or during the day, there's limited evidence that a specific time of day provides additional benefits.
When Should You Consider Magnesium Glycinate?
Magnesium glycinate may be a suitable option for those looking to support relaxation and sleep quality. It's often taken in the evening, although it can also be taken at other times.
Some people prefer magnesium glycinate because they find it gentle on digestion. However, tolerance varies, and research hasn't established that this formulation consistently improves sleep for everyone.
Can You Take Magnesium Malate and Glycinate Together?
Some people may consider taking both formulations, but combining magnesium supplements can increase your total intake beyond recommended levels.
Before combining products, account for the elemental magnesium in each supplement and any magnesium-containing medications. Consult a health care professional to determine whether combining formulations is appropriate for your needs.
How Much Magnesium Should You Take?
The recommended dietary allowance (RDA) for magnesium varies by age and sex. According to the National Institutes of Health (NIH), the RDA for adults is:
- Adult men: 400 to 420 mg per day
- Adult women: 310 to 320 mg per day
These amounts include magnesium from food, beverages, and supplements.
The tolerable upper intake level for supplemental magnesium is 350 mg per day for adults. This limit applies to magnesium from supplements and medications, not magnesium naturally present in food. Healthcare professionals may recommend different amounts in certain circumstances.
Check your supplement's label to understand how much elemental magnesium you're consuming, and consider your dietary intake before choosing a dose.
Are There Any Side Effects?
Magnesium supplements are generally well tolerated when used appropriately, but some people may experience digestive discomfort, including:
- Diarrhea or loose stools
- Nausea
- Abdominal cramping
Side effects can depend on dosage, formulation, and individual tolerance. Magnesium can also interact with certain medications, including some antibiotics and oral bisphosphonates.
If you take prescription medications or have concerns about your magnesium intake, consult a qualified health care professional before starting supplementation.
