Bursts of cortisol excretion oscillate diurnally and the amplitude of these bursts increase
during morning hours. Environmental factors and mental stress may disrupt the balance in this cycle [2].
Does magnesium lower cortisol?
Stress. Physical and emotional stress—a constant reality in our 24/7 society—drain the body of magnesium. In fact, studies show inverse relationships between serum cortisol and magnesium—

dietary doses increases both adrenocorticotropin
