If you’re struggling with fatigue, anxiety, blood sugar problems, thyroid issues or random muscle twitches, you might be low on magnesium.

Magnesium is your body’s natural chill pill. It helps regulate your heartbeat, blood sugar, nerve function and mood. But it’s easily depleted by stress, poor diet and certain medications. 

Unfortunately, magnesium deficiency often flies under the radar because the symptoms mimic other conditions. Here are 10 magnesium “drug muggers” that may be draining your levels without you knowing:

• Acid blockers like omeprazole (Prilosec) or pantoprazole (Protonix)

• H2 blockers such as famotidine (Pepcid) or cimetidine (Tagamet)

• Antacids, which interfere with stomach acid needed to absorb magnesium 

• Alcohol, which increases magnesium loss through urine

• Coffee and caffeine, due to their diuretic effect

• Decaf coffee and black tea, which can impair absorption

• Diuretics like hydrochlorothiazide (HCTZ) and furosemide

• Corticosteroids like prednisone

• Chemotherapy drugs that strip multiple nutrients

• Smoking, which lowers magnesium levels

When magnesium is low, symptoms vary widely, ranging from high blood pressure and insomnia to anxiety, muscle cramps and blood sugar imbalances. These are often treated as separate conditions, when the root cause may be a simple deficiency.

After my own parathyroid surgery, I experienced painful leg spasms due to the dysregulation of calcium. What finally worked was replenishing magnesium, calcium and key electrolytes. This combination finally restored balance and totally eliminated the cramps.

Unfortunately, nutrient deficiencies are often misdiagnosed as a chronic illness, which can lead to a frustrating cycle of medications and side effects. Since many health professionals aren’t trained to look for drug-induced nutrient depletion, a deficiency may be mistaken for a new disease.

The good news? You may be healthier than you think. Replenishing magnesium through diet or supplements might help resolve issues that seem unrelated. It also supports neurotransmitters like serotonin and dopamine, which are essential for a stable mood.

A simple blood test can reveal a magnesium deficiency—your symptoms might already be sending the signals.
