Benefits of Magnesium for Mental Calmness
Ensuring adequate magnesium intake can support your mental and emotional wellbeing in many ways, from reducing symptoms of stress to supporting sleep quality.
Reducing feelings of anxiousness
Because of magnesium’s crucial role in regulating the HPA-axis, it helps modulate cortisol levels which prevents excessive spikes that contribute to those anxious feelings (Wang et al., 2018). Magnesium interacts with GABA receptors, the brain's primary inhibitory neurotransmitter. By enhancing GABA activity, magnesium promotes a calming effect, reducing excitability in the nervous system and helping to alleviate stress (Boyle et al., 2017).
Improving sleep quality
Magnesium is essential for the regulation of melatonin, the hormone responsible for controlling the sleep-wake cycle. With it’s influence on GABA, magnesium has been shown to help quiet brain activity before sleep. Additionally, magnesium plays an important role in regulating calcium, which may help reduce muscle tension and prevent restlessness and cramping of muscles overnight. Clinical trial’s have also demonstrated that magnesium supplementation can improve sleep onset, duration, and efficiency in older adults with insomnia.
Promotes relaxation
Magnesium acts as a natural regulator of the autonomic nervous system, helping to balance sympathetic (fight-or-flight) and parasympathetic (rest-and-digest) activity. It helps modulate norepinephrine, a neurotransmitter responsible for heightening the stress response, while increasing GABA activity (which we know promotes relaxation). Magnesium’s ability to help reduce oxidative stress also contributes to its calming effects.
Supports mood stability
Magnesium plays a critical role in neurotransmitter regulation, particularly in the synthesis and release of serotonin, our ‘feel-good’ neurotransmitter. Studies have shown that low magnesium levels are associated with higher rates of mood disturbances. Magnesium also influences brain-derived neurotrophic factor (BDNF), a protein essential for brain plasticity and emotional resilience.
