Yes, low magnesium levels are strongly linked to an increased risk and symptoms of depression, as magnesium is crucial for neurotransmitter function (like serotonin) and stress regulation, with supplementation often showing positive effects on mood, though it's usually an adjuvant, not a sole treatment for severe cases. Magnesium deficiency can disrupt brain signaling, affecting mood stability and making individuals more vulnerable to low moods and stress, with studies showing a significant association between low dietary intake or deficiency and depressive disorders.
Treatment can be started with 1-2 g (8-16 mEq) of magnesium sulfate infused over 2 to 15 minutes. This dose can be repeated as necessary to maintain the plasma magnesium concentration above 1.0 mg/dL (0.4 mmol/L or 0.8 mEq/L). The maximum dose is 50 mEq, given slowly over 8-24 hours.
Magnesium intake during pregnancy
The problem arises when there is a magnesium deficiency, caused by an insufficient intake in the diet or an excessive loss that the body cannot compensate, due to intense sweating or vomiting caused by prolonged nausea during pregnancy.
Your body needs magnesium to function normally. Symptoms of magnesium deficiency include low appetite, nausea or vomiting, muscle spasms or tremors and abnormal heart rhythms. A blood test or urine test can be used to diagnose magnesium deficiency.
Magnesium deficiency
For drinks high in magnesium, opt for mineral waters, fruit juices (especially orange, cherry, watermelon), plant-based milks (soy, almond), and homemade concoctions using raw cacao, coconut milk, or magnesium powders mixed with water or smoothies, with hot chocolate (made with raw cacao) and herbal teas (like nettle) also being good choices.
Early signs and symptoms of magnesium deficiency include loss of appetite, nausea, vomiting, fatigue, and weakness. As magnesium deficiency worsens, numbness, tingling, muscle contractions and cramps, seizures, personality changes, abnormal heart rhythms, and coronary spasms can occur [1,2].
For acute deficiency symptoms, such as muscle and leg cramps, supplementation should be continued even after the symptoms have subsided. This is because, depending on the severity of the deficiency, it can take several weeks to replenish magnesium stores.
If the level of magnesium in your blood is lower than 1.8 milligrams per deciliter, your levels are considered low. If your level is below 1.25 mg/dL, your condition is considered severe. Often, doctors may not find this condition until the levels are severely low. This is when symptoms often first appear.
Know that hypomagnesemia is treatable and that symptoms usually go away once your magnesium levels are back to normal with treatment.
Moreover, the first detailed study of Mg status in ADHD also revealed Mg deficiency in 95% of children with ADHD [22]. Results of the most recent meta-analysis have demonstrated that children with ADHD have 0.105 mmol/L lower serum Mg levels than in neurotypical controls [15].
Magnesium deficiency may increase the excitability of muscle and nerve fibres. As a result, the muscles in the shoulder and neck area become tense, which can also trigger common tension headaches. Magnesium deficiency may also cause the blood vessels in the brain to constrict, leading to migraine attacks.
It's thought that your chance of getting severe depression may be partly affected by the genes you inherit from your parents.
Some research suggests that magnesium may help reduce anxiety symptoms in as little as three weeks in certain people, although results vary depending on factors such as the type and severity of anxiety and individual differences in metabolism and overall health.
Other authors indicated that patients with chronic schizophrenia present magnesium deficiency (Kirov et al., 1990; Kanofsky and Sandyk, 1991). Magnesium deficiency was also noted in psychosis induced by cancer chemotherapy (Matzen and Martin, 1985). 5.82 ± 0.11 mg/dl in the normal control group (p<0.05).
For women especially, magnesium is important because it plays a role in hundreds of different functions involved in hormone regulation. Thankfully, increasing dietary magnesium intake and taking a daily supplement can reverse symptoms and optimize blood sugar levels, mood, sleep and menstrual cycles.
People with low magnesium often experience restless sleep, waking frequently during the night. Maintaining healthy magnesium levels often leads to deeper, more sound sleep. Magnesium plays a role in supporting deep, restorative sleep by maintaining healthy levels of GABA, a neurotransmitter that promotes sleep.
Among the known magnesium deficiency causes are prescription medications such as diuretics, antibiotics, painkillers and cortisone, which can deplete magnesium levels in the body by impairing absorption or by increasing excretion by the kidneys.
Symptoms of magnesium deficiency may include:
For drinks high in magnesium, opt for mineral waters, fruit juices (especially orange, cherry, watermelon), plant-based milks (soy, almond), and homemade concoctions using raw cacao, coconut milk, or magnesium powders mixed with water or smoothies, with hot chocolate (made with raw cacao) and herbal teas (like nettle) also being good choices.
Culprit medications linked to hypomagnesemia include antibiotics (e.g. aminoglycosides, amphotericin B), diuretics, antineoplastic drugs (cisplatin and cetuximab), calcineurin inhibitors, and proton pump inhibitors.
Avocados: One whole avocado = 58 mg of magnesium. Bananas: One medium banana = 32 mg of magnesium. Papaya: One small papaya = 33 mg of magnesium. Blackberries: 1 cup = 29 mg of magnesium.
Drinking enough water isn't always enough. Your body needs the right minerals to absorb and retain hydration properly. Magnesium is a key electrolyte that ensures efficient water absorption at a cellular level.
Some good sources of magnesium are:
