Are You Magnesium Deficient?
8 Signs You're Missing This Critical Mineral
Over 80% of Americans are deficient in magnesium — the mineral that controls 300+ enzymatic reactions. The problem? Standard blood tests almost always miss it.
Why Your Doctor Probably Missed It
Standard serum magnesium tests measure magnesium in your blood — but only 1% of your body's magnesium is in the blood. The other 99% is in your cells and bones. You can have critically low cellular magnesium with a "normal" blood test.
The 8 Warning Signs
Muscle Cramps & Twitches
Magnesium is required for muscle relaxation. Without it, muscles stay in a contracted state. Nighttime leg cramps are one of the most reliable indicators of deficiency.
Anxiety & Irritability
Magnesium is required for GABA production — your brain's primary calming neurotransmitter. Low magnesium = low GABA = anxiety, irritability, and a racing mind.
Poor Sleep Quality
Magnesium regulates melatonin production and activates the parasympathetic nervous system. Deficiency makes it hard to fall asleep and stay in deep sleep stages.
Chronic Fatigue
Magnesium is essential for ATP synthesis — the energy currency of every cell. Without adequate magnesium, your mitochondria can't produce energy efficiently.
Headaches & Migraines
Multiple studies show that magnesium deficiency is present in 50% of migraine sufferers during attacks. IV magnesium is now used in emergency rooms to abort migraines.
High Blood Pressure
Magnesium acts as a natural calcium channel blocker, relaxing blood vessel walls. Deficiency causes vasoconstriction and elevated blood pressure.
Constipation
Magnesium draws water into the intestines and stimulates peristalsis. It's one of the most effective natural remedies for constipation — and deficiency is a common cause.
Heart Palpitations
Magnesium regulates the electrical activity of the heart. Deficiency can cause irregular heartbeat, palpitations, and in severe cases, arrhythmias.
Why We're All Deficient
Modern soil is depleted. Industrial farming has stripped magnesium from the soil over the past 50 years — meaning even "healthy" foods contain a fraction of the magnesium they once did. A 1950s apple had 4x more magnesium than today's.
Stress depletes magnesium rapidly. Every time your adrenal glands fire cortisol, magnesium is excreted in the urine. Chronic stress creates a vicious cycle: stress depletes magnesium, low magnesium amplifies the stress response.
Which Form to Take
Highest bioavailability. Crosses the blood-brain barrier. Best for anxiety, sleep, and general deficiency. No laxative effect at normal doses.
Only 4% absorbed. The cheapest form — found in most drugstore supplements. Causes GI distress and does almost nothing for cellular magnesium.
Specifically designed to cross the blood-brain barrier. Best for cognitive function, anxiety, and neurological symptoms. More expensive.
Well-absorbed. Draws water into the intestines. Good for constipation but can cause loose stools at higher doses.
Our Recommendation
Start with 400mg of magnesium glycinate before bed. Most people notice improved sleep within 3–7 days. For anxiety, add a morning dose. Give it 4–8 weeks for full cellular repletion.
