Magnesium is increasingly associated with stress levels.
Although the exact mechanisms of action as to how magnesium works to regulate stress is still unclear, a growing body of research continues to support that magnesium is a critical component in our bodies ability to cope with stress.*
Magnesium helps to suppress the release of excess stress hormones like cortisol.*
Chronic stress has been linked with lower intracellular magnesium levels.*
Low magnesium levels have been linked to restless sleep. While healthy magnesium levels has been associated with healthier sleep cycles.
Magnesium promotes deep restful sleep by helping to maintain healthy levels of the neurotransmitter GABA. By raising GABA levels, magnesium may promote relaxation, and has been found to improve sleep quality.*
Science has recently awakened to the role of zinc in promoting restful sleep.*
Zinc's beneficiary role in regulating sleep is not well understood, but early studies suggest it may facilitate deep sleep: the non-dreaming sleep associated with physical restoration and memory.
Although taking zinc before bed doesn't actively signal to your body that it's time to sleep: alleviating a zinc deficiency may help with sleep latency (the time it takes you to fall asleep), help you stay asleep longer, and improve the overall quality of your sleep.*
Low magnesium levels are associated with depressed mood.*
A correlation that may have something to do with magnesium's role in helping to regulate serotonin levels, a neurotransmitter associated with healthy mood.*
