The Third Sign: Noticeable Changes in Mental Health and Mood.
Magnesium exerts a profound influence on your neurological system by regulating neurotransmitters, the chemical messengers that transmit signals throughout your brain. A severe deficiency directly impairs the function of the hypothalamic-pituitary-adrenal (HPA) axis, which controls how your body responds to stress.
As a result, early shortfalls often manifest as emotional apathy, heightened anxiety, or an uncharacteristic lack of interest in daily activities. When your nervous system lacks this natural relaxant, you may also find yourself feeling unusually irritable, overwhelmed, or trapped in a state of brain fog.
