Home Remedies & Natural Solutions
Magnesium-Rich Foods
Include dark chocolate, avocados, nuts (especially almonds and cashews), legumes, tofu, seeds (pumpkin, chia), and leafy greens in your diet.
Epsom Salt Baths
Soak in warm water with 2 cups of Epsom salts for 20 minutes. Magnesium can be absorbed through the skin.
Reduce Magnesium Depleters
Limit coffee, alcohol, sugar, and processed foods which can deplete magnesium or interfere with absorption.
Magnesium Supplements
If diet isn't enough, consider supplements. Magnesium glycinate is gentle on the stomach and good for sleep. Citrate helps with constipation.
Note: Home remedies may help relieve symptoms but are not substitutes for medical treatment. Consult a healthcare provider before trying any new remedy, especially if you have underlying health conditions.
FDA-Approved Medications
Important: The medications listed below are FDA-approved treatments. Always consult with a healthcare provider before starting any medication. This information is for educational purposes only.
Magnesium Oxide
Common OTC supplement with high magnesium content but lower absorption. Often used for constipation.
Warning: May cause diarrhea. Not the best choice for correcting deficiency due to poor absorption.
Magnesium Citrate
Better absorbed form of magnesium. Also used as a laxative at higher doses.
Warning: Can cause loose stools. Take with food to reduce GI effects.
Magnesium Sulfate (IV)
Used in hospitals for severe deficiency, eclampsia, or certain heart arrhythmias.
Warning: Requires medical supervision. Side effects include flushing and low blood pressure.

- Muscle spasms or cramps that don't resolve
- Heart palpitations or irregular heartbeat
- Severe fatigue affecting daily life
- Numbness or tingling in extremities
- Seizures or confusion
- You have diabetes, GI disease, or take depleting medications

Talk to a Healthcare Provider
If your symptoms are persistent, severe, or concerning, please consult with a qualified healthcare professional for proper evaluation and personalized advice.
Frequently Asked Questions about Magnesium Deficiency
Click on a question to see the answer.
Blood tests can show severe deficiency, but serum magnesium only reflects 1% of body stores. A red blood cell (RBC) magnesium test is more accurate. Symptoms and dietary assessment are also important.
Magnesium glycinate and magnesium malate are often recommended for fatigue. Glycinate is calming and good for sleep, while malate may help with energy production. Avoid oxide for fatigue as it's poorly absorbed.
From food, excess is excreted. From supplements, too much can cause diarrhea, nausea, and in extreme cases, dangerous drops in blood pressure. The upper limit for supplements is 350mg/day for adults, though higher doses may be prescribed medically.
