Magnesium Glycinate vs. Citrate on Keto: Solving Nighttime Muscle Cramps
Waking up at 3 AM with a locked calf muscle is a classic sign of magnesium depletion. Why chemical chelation matters and which formulation to buy.
You wake up in the middle of the night with your calf muscle seized in a violent, agonizing spasm. Nocturnal muscle cramps are the hallmark sign of magnesium depletion on a ketogenic diet. Magnesium regulates cellular neuromuscular conduction and actin-myosin relaxation. But when shopping for supplements, grabbing the wrong bottle will give you severe digestive distress instead of relief.
1. Magnesium Oxide and Citrate: The Osmotic Laxatives
Cheap drugstore magnesium is almost always Magnesium Oxide, which has an abysmal 4% bioavailability. Nearly all of it passes directly into the colon, causing diarrhea.
Magnesium Citrate is moderately better absorbed, but the citric acid bond still exerts significant osmotic pull, making it an excellent treatment for constipation but suboptimal for systemic neuromuscular repletion.
2. Magnesium Glycinate: The Neurological Gold Standard
Magnesium Glycinate binds elemental magnesium to the calming inhibitory neurotransmitter glycine.
It boasts superior intestinal absorption via dipeptide channels, causing zero loose stools. Furthermore, glycine crosses the blood-brain barrier, binds NMDA receptors, and lowers core body temperature, dramatically improving deep-stage sleep architecture while extinguishing muscle cramps.
Take 300mg to 400mg of chelated Magnesium Glycinate 45 minutes before sleep to permanently end nighttime leg cramps and support deep neurological recovery.
