Magnesium is just starting to get the attention it deserves. This essential mineral plays a critical role in keeping your body functioning at its best. Whether you’re looking to support your energy levels, improve sleep, or relax tight muscles, magnesium is your ally. Despite its importance, many people are not getting enough magnesium in their diets, and understanding the types of magnesium and where to get it can make all the difference.
In this blog, we’ll explore why magnesium is vital for your health, the different forms it takes, and how you can incorporate it into your daily routine through food and supplements. Read to the end for your free gift!
Let’s start with the science…
If you hate science feel free to skip to the next section (for a brief summary of the science)… but for us science nerds let’s get into the nitty gritty. If you studied biochemistry, biology, or chemistry at the college level you may remember that Magnesium is a macro-mineral and an essential co-factor in many enzymatic reactions (over 300 to be specific) in the body. It acts as a stabilizer for biochemical processes, helping to regulate everything from energy production to DNA synthesis. At the molecular level, magnesium’s divalent cation charge (Mg²⁺) allows it to bind to negatively charged molecules like ATP, proteins, and nucleic acids, enabling critical reactions in the body.
Key Biochemical Roles of Magnesium
Energy Production (ATP Activation): Magnesium is vital for energy metabolism because ATP (adenosine triphosphate), the body’s energy molecule, exists in the body as Mg-ATP. The Mg²⁺ ion stabilizes the phosphate groups of ATP, making it possible for ATP to release energy during cellular reactions. Without magnesium, ATP cannot function properly, leading to decreased energy production.
Enzymatic Cofactor: Magnesium serves as a co-factor for hundreds of enzymes involved in metabolic pathways, including:
Glycolysis: Breaking down glucose to produce energy.
Krebs Cycle: Magnesium-dependent enzymes like isocitrate dehydrogenase help generate NADH for the electron transport chain.
DNA and RNA Synthesis: Magnesium stabilizes nucleotides and supports enzymes like DNA polymerase in transcription and replication.
Protein Synthesis: Magnesium helps in the structural stabilization of ribosomes, the cellular machinery that synthesizes proteins. It ensures the proper alignment of tRNA and mRNA during translation, enabling accurate protein production.
Ion Transport and Muscle Function: Magnesium regulates ion channels for sodium (Na⁺), potassium (K⁺), and calcium (Ca²⁺). By controlling calcium influx in muscle cells, magnesium helps muscles contract and relax. Too little magnesium leads to unregulated calcium entry, causing muscle cramps and spasms.
Nervous System Regulation: Magnesium plays a role in balancing excitatory and inhibitory neurotransmitters in the brain. It blocks NMDA (N-methyl-D-aspartate) receptors, which reduces excessive stimulation of nerve cells and promotes relaxation and calmness.
Bone Health: Magnesium interacts with calcium and vitamin D to regulate bone density. About 60% of magnesium in the body is stored in bones, where it supports mineralization and structural stability. Magnesium deficiency can disrupt calcium metabolism, contributing to osteoporosis.
Biochemical Impact of Magnesium Deficiency
When magnesium is insufficient, the body’s ability to perform critical reactions becomes compromised, leading to:
Impaired ATP Production → Fatigue and decreased energy.
Unregulated Calcium Influx → Muscle cramps and irregular heart rhythms.
DNA/RNA Disruption → Poor cell repair and function.
Overactive NMDA Receptors → Anxiety, headaches, and stress.
To summarize…
Magnesium is very important, it is involved in…
Energy Production: Magnesium is required to produce ATP (adenosine triphosphate), the body’s energy currency.
Muscle Function: It helps muscles contract and relax, preventing cramps and spasms.
Nerve Function: Magnesium plays a key role in nerve signaling, calming the nervous system.
Bone Health: Around 60% of the body’s magnesium is stored in the bones, where it helps maintain strength and structure.
Heart Health: Magnesium regulates your heartbeat and supports healthy blood pressure.
Sleep and Stress Management: It helps calm the body, improving sleep quality and reducing stress.
With so many functions, a magnesium deficiency can cause noticeable issues, such as fatigue, muscle cramps, irregular heartbeats, poor sleep, and even headaches.
Why Are People Low in Magnesium?
Without the proper tests, serum levels may not be accurate leading to misinformation. Unfortunately, magnesium deficiency is common, particularly in Western diets. Several factors contribute to this:
Poor Diet: Processed and refined foods lack magnesium. Whole, unprocessed foods (nuts, seeds, grains, and vegetables) are the best sources.
Depleted Soils: Modern farming practices have reduced the amount of magnesium in the soil, leading to lower levels in crops.
Chronic Stress: Stress increases the body’s magnesium needs, and low levels of magnesium make it harder to manage stress.
Certain Medical Conditions: Diabetes, gastrointestinal issues (like Crohn’s), and kidney diseases can impact magnesium absorption.
Different Forms of Magnesium and Their Benefits
Not all magnesium supplements are the same. Depending on the compound it’s bound to, magnesium has different levels of absorption and specific benefits. Here’s a breakdown of the most common types:
Magnesium Glycinate
What it is: Magnesium bound to glycine, an amino acid.
Benefits: Highly absorbable, gentle on the stomach, and excellent for promoting sleep, reducing stress, and relaxing muscles.
Best For: General health, stress, and sleep support.
Magnesium Citrate
What it is: Magnesium bound to citric acid.
Benefits: Great for digestion, relieving constipation, and improving bowel regularity.
Best For: Digestive issues and occasional constipation.
Magnesium Malate
What it is: Magnesium bound to malic acid, naturally found in apples.
Benefits: Supports energy production, reduces fatigue, and helps with muscle pain.
Best For: Energy support and muscle recovery.
Magnesium L-Threonate
What it is: Magnesium bound to threonic acid, which can cross the blood-brain barrier.
Benefits: Improves brain function, memory, and cognitive health.
Best For: Brain health and focus.
Magnesium Oxide
What it is: Magnesium bound to oxygen.
Benefits: Low absorption, primarily used for short-term relief of constipation.
Best For: Occasional bowel relief (not ideal for overall magnesium support).
Magnesium Chloride
What it is: Magnesium combined with chloride.
Benefits: Easily absorbed and often used in topical oils to support muscle recovery.
Best For: Muscle relaxation and topical application.
Each form of magnesium has its strengths, but if you’re looking for one form for overall health, Magnesium Glycinate is often the best choice due to its high absorption and versatility.
Magnesium in Foods: The Natural Source
The best way to get magnesium is through a well-balanced diet rich in whole foods. In food, magnesium is naturally bound to other compounds, like chlorophyll in plants or malic acid in fruits, making it bio-available and easy for the body to use.
Here are some of the top food sources of magnesium:
Magnesium in the Body: Why It’s Used in Different Ways
Once magnesium is absorbed into your body, it plays specific roles in different systems. For example:
In Muscles: Magnesium relaxes muscle fibers after contraction, preventing cramps and spasms.
In Bones: Magnesium works with calcium to build strong bones and regulate bone density.
In Nerves: It regulates neurotransmitters like GABA, calming the nervous system and supporting better sleep.
In Cells: Magnesium helps produce cellular energy (ATP), which powers all bodily functions.
In the Brain: Certain forms of magnesium (like L-threonate) support brain function, focus, and memory.
This is why different forms of magnesium supplements target specific benefits, while food-based magnesium provides a natural mix for overall health.
Are You Getting Enough Magnesium?
The recommended daily intake of magnesium varies based on age and gender:
Women: 310–320 mg/day
Men: 400–420 mg/day
While the body can excrete excess magnesium through urine, taking too much from supplements can cause:
Diarrhea
Nausea
Abdominal cramping
Focus on magnesium-rich foods first and use supplements to fill in gaps or target specific needs.
