Evening, 30-60 min before bed
Magnesium is an essential mineral that participates in over 300 enzymatic processes throughout the body, including energy production, protein synthesis, and neuromuscular function. Despite its critical role, dietary intake is frequently inadequate due to soil depletion and processed food consumption, making it one of the most common nutrient deficiencies in developed countries.
