Why Magnesium Matters for Energy
Magnesium plays a crucial role in over 300 enzymatic reactions in the body, including ATP production. Adenosine triphosphate (ATP) is the primary energy currency of cells. Research suggests that adequate magnesium levels are essential for maintaining healthy energy metabolism.
A deficiency in magnesium can lead to symptoms like fatigue and muscle weakness. The recommended daily allowance (RDA) for magnesium for adult women is 310-320 mg, and for adult men, it is 400-420 mg. Many individuals do not meet these requirements through diet alone.
