Symptoms of Magnesium Deficiency
Constant tiredness or fatigue
Muscle cramps and tremors
General weakness
Nausea or loss of appetite
Anxiety, irritability, or insomnia
Irregular heartbeat
If you experience several of these symptoms, it is best to consult a healthcare professional and have a blood test.
Natural Sources of Magnesium
A balanced diet is the best way to obtain this mineral naturally.
Among the foods richest in magnesium are:
Spinach and Swiss chard
Almonds and walnuts
Pumpkin seeds
Avocado
Legumes (lentils, chickpeas, beans)
Bananas
Wholegrain oats
Dark chocolate (minimum 70%)
Tofu
Fatty fish such as salmon or mackerel
Including these foods regularly is enough to maintain healthy levels without the need for supplements.
When is Magnesium Supplementation Recommended?
Although ideally magnesium should be obtained through diet, there are situations where supplementation may be necessary, such as:
Gastrointestinal problems that hinder absorption.
Athletes or people who sweat excessively.
Pregnant or breastfeeding women.
Older adults.
People under chronic stress or with poor sleep quality.
Supplements come in different forms (citrate, glycinate, chloride, oxide, etc.), and each has a different absorption rate. Always consult a doctor before starting any supplement.
Recommended Daily Intake (RDI)
Requirements vary according to age and sex:
Adult men: 400–420 mg daily
Adult women: 310–320 mg daily
Pregnant women: 350–360 mg daily
Adolescents: 360–410 mg
Children: 80–240 mg
Excess intake can cause digestive discomfort (such as diarrhea or nausea), so it is important not to exceed the recommended doses.
Who is at Higher Risk of Deficiency?
People with type 2 diabetes
Patients with intestinal diseases (Crohn’s disease, celiac disease, colitis)
Frequent alcohol consumers
Those who take diuretics or antibiotics for extended periods
These individuals should pay special attention to their magnesium intake and supplement it through diet or under medical supervision.
Conclusion
Magnesium is an essential mineral for energy, muscles, the nervous system, and bones.
Maintaining adequate levels can help you feel more energetic, sleep better, and reduce daily stress.
Reasoning for its benefits doesn’t require major changes: a balanced diet, proper hydration, and consistency are all it takes.
Magnesium not only improves physical health but also mental and emotional well-being.
