Magnesium plays an important role in cell-to-cell communication [R].
Over 300 enzymes require the presence of magnesium to function properly [R].
Because of its positive charge, magnesium stabilizes the cellular cover (membranes) [R].
Magnesium can benefit even people who are not ‘deficient’.
Magnesium is important for:
- bone health [R]
- muscle contraction and relaxation [R, R]
- heart rhythm and blood pressure [R]
- stabilizing blood glucose levels, and regulating sugar and fat metabolisms [R, R]
- neurotransmitter production and regulation [R],
- neural function [R]
- the immune system [R]
Low consumption of magnesium is common throughout the world [R].
Dietary magnesium intakes among most American adults are low. A study estimated the magnesium intake from food sources to 261 mg in women and 347 mg in men, which is well below the RDA (320 mg for women and 420 mg for men) [R].
Low magnesium levels in the body may occur due to defects in its absorption or as a result of its loss via kidneys (in case of diabetes, alcoholism, treatment with antidiuretics, aminoglycosides, fluoroquinolones, cisplatin, digoxin, cyclosporine, amphotericin B).
Magnesium excretion increases while absorption decreases with age, because of various chronic diseases and decreased intake of foods high in magnesium [R].
Magnesium deficiency produces a variety of neuromuscular and psychiatric symptoms such as hyperexcitability, agitation, tetany (involuntary muscle contractions), headaches, seizures, ataxia, vertigo, muscular weakness, tremors, irritability, anxiety, insomnia, nervous fits, faintness, fatigue, confusion, hallucinations, and depression [R].
Severe dietary magnesium restriction has a detrimental effect on metabolism, glucose balance, and retention and excretion of other minerals [R].

Below, I give a bunch of different good options to buy Magnesium, but some people want to to know which one I take.
Health Benefits of Magnesium
1) Magnesium Can Improve Physical Performance
Magnesium is required for proper muscle function, both at rest and during exercise [R].
Magnesium depletion is associated with increased inflammation, muscle cell alterations, and impaired calcium balance in the cells [R].
Other studies failed to find improvements in muscle strength and function [R].
Generally, magnesium supplements have a greater effect when dietary intake or blood levels are low [R].
Magnesium supplements prevent or delay an age-related decline in physical performance [R].
Daily magnesium oxide supplementation for 12 weeks improved physical performance in healthy elderly women [R].
2) Magnesium Maintains Bone Integrity
Lower magnesium intake is associated with lower bone mineral density and promotes osteoporosis [R].
On the other hand, elevated magnesium may have a harmful effect on bone metabolism and parathyroid gland function, leading to mineralization defects [R].
Magnesium excess (5–10 times nutrient requirements) in rats had no effect on bone mineral density in short-term but lowered bone mineral density in long-term studies [R].
Bone lesions and lower bone mineral density were recorded in cases of acute exposure to high-dose magnesium in humans.
Magnesium consumption slightly greater than the RDA was associated with increased lower-arm and wrist fractures that were possibly related to more physical activity and falls [R].
3) Magnesium Reduces Blood Pressure
4) Magnesium Protects against Cardio-Vascular Disease
Magnesium is required for the normal electrical activity of the heart, and has beneficial effects on the cardiovascular system, by widening blood vessels, improving fat metabolism, reducing inflammation, and inhibiting blood platelet aggregation.
Low magnesium and experimental restriction of dietary magnesium increase cardiac arrhythmias.
Increase in circulating magnesium was associated with a 30% lower risk of cardiovascular disease, while dietary magnesium was associated with a 22% lower risk of ischemic heart disease.
An increased consumption of magnesium-rich foods, such as whole grains, nuts, and vegetables has been estimated to lower the risk of cardiovascular mortality by 28% [R].
My personal preference is to skip the lectins and take magnesium supplements and eat veggies.
Self-reported magnesium intake was inversely associated with hardening of the arteries (calcification), which may play a contributing role in magnesium’s protective associations in stroke and fatal heart disease [R].
5) Magnesium Lowers the Risk of Diabetes and Insulin Resistance
Low magnesium levels play a role in the development of insulin resistance. Nondiabetic patients with low serum magnesium are significantly more likely to have insulin resistance, glucose intolerance and elevated insulin levels compared to patients with higher magnesium levels.
Low magnesium has been implicated in the cause of liver disease, especially non-alcoholic fatty liver disease and nonalcoholic steatohepatitis. Both conditions are strongly associated with insulin resistance, as well as obesity, type 2 diabetes, elevated fat levels and high blood pressure [R].
Magnesium was inversely associated with metabolic syndrome [R], and oral magnesium supplementation improved the metabolic profile and lowered blood pressure of metabolically obese and normal-weight individuals [R].
In the study, blood pressure, insulin resistance, fasting glucose and triglyceride levels all decreased significantly in the subjects who received Magnesium chloride compared with individuals who didn’t [R].
Lower magnesium intake was associated with higher risk of diabetes in the Taiwanese population [R].
Greater magnesium intake was associated with lower risk of type 2 diabetes and metabolic abnormalities [R].
Increased consumption of magnesium-rich foods such as whole grains, beans, nuts, and green leafy vegetables may reduce the risk of type 2 diabetes [R].
Evidence suggests that insulin sensitivity, elevated blood sugar, type 2 diabetes and elevated fat content in the blood can be improved with increased magnesium intake [R].
6) Magnesium is Beneficial for Nerve and Brain Function
Elevation of brain magnesium can enhance learning and prevent overgeneralization of fear in rats [R].
Magnesium supplements have been shown to significantly improve functional recovery in various neurological disorders.
Magnesium supplements improved neurobehavioral, electrophysiological functions, enhanced nerve regeneration and reduced inflammation in mice [R].
7) Magnesium Relieves Headaches and Migraines
Magnesium deficiency can lead to brain artery spasm and increased the release of pain substances (such as substance P).
Significantly lowered serum magnesium levels have been seen in migraine and tension headache sufferers.
A high dose (600 mg) of oral magnesium daily for 12 weeks significantly reduced the frequency of headaches by 41.6%, and also reduced the severity, drug usage, and duration of the acute attacks [R].
Intravenous magnesium sulfate in acute migraine sufferers with a known low serum magnesium level leads to remission of the attack.
Magnesium supplements, along with routine treatment, significantly improved all migraine indicators [R].
8) Magnesium Relieves Chronic Fatigue Syndrome
Stress hormones, including both catecholamines and corticoids, can cause a reduction in tissue magnesium levels.
Many of the symptoms and findings in chronic fatigue syndrome resemble those of magnesium deficiency.
A referral center that evaluated several hundred chronic fatigue syndrome patients observed that half of their patients were magnesium-deficient [R].
9) Magnesium Reduces Anxiety and OCD
Magnesium supplementation is effective in treating anxiety and anxiety-related disorders when used in combination with other vitamins, minerals and herbal extracts [R].
Magnesium relieved premenstrual anxiety in women, when taken together with B6 [R].
Partial magnesium-depletion increased anxiety-related behavior in mice [R].
Magnesium’s anti-anxiety role is mediated in large part by its ability to block NMDA receptors [R].
10) Magnesium Reduces Depression
Magnesium plays a role in many of the pathways involved in depression and is found in several enzymes, hormones, and neurotransmitters [R].
Mice consuming a diet with very low magnesium content—consisting of only 10% of the daily requirement—showed depressive behavior [R].
Low magnesium status has been associated with increased depressive symptoms in several different age groups and ethnic populations [R].
Administration of magnesium sulfate to rats subjected to traumatic brain injury significantly decreased both incidences of post-traumatic depression and its severity [R].
Co-treatment of magnesium salts and antidepressants from different classes (i.e., fluoxetine, imipramine, and bupropion) resulted in the synergistic antidepressant-like effect [R].
Case studies of magnesium supplementation reported improvements in depression, anxiety, and sleep within one week. Surprisingly, in one study, low magnesium intake in older adults seemed to protect from depression [R].
11) Magnesium May be Beneficial in ADHD
Magnesium supplementation may be beneficial in treating attention-deficit/hyperactivity disorder (ADHD).
12) Magnesium is Beneficial for Skin Allergies
Magnesium deficiency impairs immunity. Topical and oral administration of magnesium salts had beneficial effects in patients with skin allergy [R].
13) Magnesium Decreases Inflammation
Magnesium sulfate (Epsom salt) exposure before preterm birth is neuroprotective, reducing the risk of cerebral palsy and major motor dysfunction.
In pregnant mothers, magnesium sulfate reduced maternal TNF and IL-6 production and substantially reduced the frequency of the baby’s monocytes producing TNF-α and IL-6 under stimulated conditions [R].
The immunomodulatory effect was mediated by magnesium rather than sulfate, and it was reversible [R].
14) Magnesium May Slow Aging
Several pieces of evidence link low Magnesium to aging and age-related diseases. Studies have shown that cultures in low magnesium (Mg) accelerates the death of human endothelial cells and fibroblasts [R].
Magnesium inadequacy interferes with cellular metabolism, which could affect this process.
15-16) Magnesium is Critical For The Mitochondria and Antioxidant Function
Magnesium in the mitochondria accounts for one-third of total cellular magnesium [R]. Magnesium forms a complex with ATP, which is an important source of stored energy.
A large portion of the energy used in humans is produced by mitochondria through the movement of electrons over the respiratory chain.
Magnesium is critical for basic mitochondrial functions, including ATP synthesis, electron transport chain complex subunits, and oxygen detoxification [R].
Inadequate availability of magnesium may lead to reduced mitochondrial efficiency and increased production of reactive oxygen species with consequent structural and functional impairment to proteins, DNA, and other essential molecules.
Studies of magnesium-deficient cultured human cells and animals show evidence of decreased antioxidant capacity and mitochondrial swelling in magnesium-deficient animals [R].
Hence, magnesium seems fundamental for the control of oxidative stress and to maintain the normal function of mitochondria.
17) Magnesium Prevents Cancer
Magnesium deficiency, by exacerbating chronic inflammatory stress, may play a role in the onset of cancer.
Middle-aged men with higher serum magnesium concentrations had a 50% lower risk of cancer death than those with low serum magnesium [R].
Magnesium intake may be beneficial in terms of primary prevention of pancreatic cancer. Every 100 mg per day reduction in magnesium intake was associated with a 24% increase in the incidence of pancreatic cancer [R].
18) Magnesium is Beneficial in Pregnancy
Gestational magnesium deficiency may cause developmental defects [R].
Women receiving magnesium were significantly less likely to require hospitalization during pregnancy [R].
Magnesium supplementation among women with pregnancy-induced diabetes had beneficial effects on metabolic status and pregnancy outcomes [R].
Transfer of large amounts of magnesium from mother’s blood to the fetus with other nutrients may contribute to the occurrence of post-pregnancy depression (by causing magnesium deficiency in the mother) [R].
19) Magnesium May Relieve Pancreatitis
Nutritional magnesium deficiency increases the susceptibility of the pancreas towards disease, by elevating calcium concentrations. Elevated calcium is an established risk factor for pancreatic inflammation (pancreatitis).
Magnesium administration reduced pancreatic enzyme activities, tissue swelling and death, and inflammation during pancreatitis in rats [R].
20) Magnesium Protects From Kidney Function Decline
Low magnesium is associated with increased risk of death and kidney function decline in chronic kidney disease patients as well as mortality in dialysis patients [R].
Cisplatin, a commonly used chemotherapeutic for ovarian and other cancers, reduces magnesium levels in most patients and causes acute kidney injury in 25-30% of patients.
Magnesium supplementation during cisplatin treatment protects against cisplatin-mediated acute kidney injury in mice [R].
Additionally, magnesium supplement therapy was significantly associated with both reduced frequency and reduced severity of kidney toxicity in patients receiving cisplatin [R].
21) Magnesium Prevents Hearing Loss
Magnesium intake acts synergistically with antioxidants to prevent hearing loss [R].
Drawbacks and Side Effects of Magnesium
Chronic high dietary magnesium exposure causes potential thyroid disruption in rats and humans [R].
Magnesium can also cause loose stools and “make you go”.
In patients with chronic renal failure or in individuals undergoing dialysis, serum magnesium concentrations are frequently elevated and correlate with mineralization defects [R].
Chronic high dietary magnesium exposure causes potential thyroid disruption [R].
Sources of Magnesium
Consumption of these foods can easily elevate magnesium levels [R].
Magnesium-containing supplements are generally well-tolerated with very few reported side effects [R]. Side effects include gastrointestinal upset such as nausea, vomiting, or diarrhea in some people [R].
Magnesium supplementation provides quick results. Case studies of magnesium supplementation reported improvements in depression, anxiety, and sleep within one week.
Bioavailability and Dosing
Not all supplements of magnesium are readily absorbed [R].
Organic forms of magnesium like aspartate, citrate, lactate, fumarate, acetate, ascorbate and gluconate have greater solubility and bioavailability in comparison to inorganic forms like oxide, sulfate, chloride, and carbonate [R].
A magnesium chelate such as magnesium citrate is considered safe for doses up to 600 mg per day in adults [R].
Evaluation of both circulating and dietary magnesium is important because circulating magnesium reflects not only diet but also gastrointestinal absorption and renal regulation [R].
High doses (>10mg/kg/d) of magnesium can be toxic [R].
Magnesium on SelfDecode
If you’re interested in a supplement that provides a full package approach to superior cognitive function and health, we recommend Qualia, which contains Magnesium and many other great brain-boosting ingredients. Use the coupon code ‘Selfhacked’ and get 10% off a 1-time order or 15% off of a recurring order.
Different forms of magnesium have different effects.
I personally take the magnesium that has butyrate, because I like the butyrate.
The ionic mineral forms are good if you can stomach the taste.
The citrate form is the standard, well-absorbed variety.
The magnesium Calm is the best when taken if you want to go to sleep because it makes you tired.
The magnesium glycinate is good if you’re looking for some more glycine.
The magnesium lactate is good if you’re looking for more lactate.
The Epsom salt bath is good because it’s not passing through the gut, so you can probably get more magnesium before you have loose stools. The downside is preparing the bath!
Magnesium cream/oil is good because the slower absorption, but the issue I’ve found with the creams are that they itch and they make a mess.
The threonate version is better for cognitive enhancement, according to one study.
If you want extra malate, then go with magnesium malate. Malate is a good chelator and also good for energy production.
