You are taking magnesium regularly but not noticing any real change. The problem may not be the supplement, but how your body is absorbing and using it.

 Your body only absorbs a portion of the magnesium you consume. Even under normal conditions, a significant amount passes through without being fully used.

Magnesium is absorbed in your gut. Digestive issues or an imbalanced gut can reduce how much actually enters your system.

Magnesium competes with other minerals like calcium and can bind with certain compounds in food, reducing how much your body absorbs.

Chugging multiple coffees or alcoholic drinks daily acts as a severe diuretic. This forces your kidneys to rapidly flush out stored magnesium through urine before your body absorbs it.

Your body needs optimal vitamin D levels to properly absorb magnesium. In its absence, your digestive tract simply cannot process this crucial relaxing mineral efficiently today.

Different forms of magnesium vary in absorption. Some common types are less bioavailable, which means your body cannot use them efficiently.
