Using Magnesium for Sleep and Anxiety
Magnesium (Mg) is present within every cell type in every organism on earth. It is an essential mineral with a broad range of biological functions, serving as a cofactor in over 350 biochemical reactions. A cofactor is a substance whose presence is essential for the activity of an enzyme. For example, the process that makes the “master antioxidant” glutathione requires magnesium, and stress-related anxiety disorders have been associated with reduced glutathione levels [1].
Magnesium is also involved in modulating the hypothalamic-pituitary-adrenal (HPA) axis [2], which is responsible for the output of cortisol, the primary stress hormone in humans. Several other mechanistic pathways associate magnesium as necessary for stress management, such as interactions with the GABA receptor [3] and possibly serotonin, all of which have broad implications for sleep and anxiety.
Chronic alcohol use can deplete magnesium [4]. Several medications can lead to depleted magnesium levels, such as proton-pump inhibitors. Individuals with gastrointestinal diseases might also be at risk for magnesium inadequacy. If you are vulnerable to the potential negative effects of magnesium deficiency, specific foods and dietary supplements recommended below may improve your mental health and sleep quality.
Magnesium and Sleep
Poor sleep and anxiety are strongly associated with stress and have been described as a reciprocal relationship [5]. Symptoms of magnesium deficiency and stress are very similar, the most common being irritability, fatigue, and mild anxiety [6]. In a longitudinal study of over 5,000 adults, magnesium intake was associated with better sleep quality [7]. In clinical practice, we often recommend magnesium supplementation at night to assist with sleep disorders.
Magnesium and Anxiety
Anxiety can be described as the experience of excessive worry, nervousness, or apprehension associated with physical, cognitive, and behavioral symptoms. To date, the available evidence suggests that the effect of magnesium supplementation is more notable in improving depression than anxiety [8] but that magnesium has a beneficial effect on subjective anxiety among those already vulnerable to anxiety [2]. In clinical practice, magnesium is often recommended to individuals with anxiety in conjunction with other lifestyle medicine approaches. It may also be wise to reduce caffeine intake if you are experiencing anxiety symptoms.
Foods High in Magnesium
Magnesium is widespread in green leafy vegetables, legumes, nuts, seeds, and whole grains. A higher intake of ultra-processed foods has been inversely associated with magnesium content in the diet [9]. The best sources of magnesium include pumpkin seeds (156 mg/oz.) and chia seeds (111 mg/oz.). Other good sources include almonds (80 mg/oz.) and black beans (60 mg/oz.) This is one of the reasons why the Wise Mind Nutrition framework includes beans, nuts, and seeds as a unique food group.
Supplemental Forms of Magnesium
Because magnesium is a positively charged cation (2+), it must be bound to an anion as a salt for stability. The compound that magnesium is bound to may matter for some more than others. Some experts suggest that the binding compound does not matter much; it is the elemental magnesium that matters. Supplements include magnesium citrate, magnesium oxide, magnesium carbonate, magnesium glycinate, and others. Magnesium citrate and oxide are known to have laxative effects, whereas magnesium carbonate and glycinate are most useful for sleep. Magnesium L-threonate has recently been suggested to cross the blood-brain barrier best.
Dosing Magnesium for Anxiety and Sleep
The recommended dietary allowance (RDA) for magnesium is 400 mg. More than half of US adults need to get more [10]. The tolerable upper intake level for supplemental magnesium is 350 mg. Note that this is the molecular weight of the actual magnesium, not the salt form. Check the label for details and refer to Consumer Lab for more information. Start with 200 mg and increase if necessary. If loose stools are present as side effects of magnesium, try switching to another formulation. Experiment with magnesium carbonate, glycinate, and L-threonate to determine which is best for you. Magnesium salt baths are also an excellent option to decrease anxiety and prepare for an excellent night's rest.
Conclusion
Suppose you prefer to meet your magnesium needs with food rather than supplements. In that case, the Wise Mind Nutrition program is a food-first approach that offers ideas and recipes for getting adequate magnesium without relying on pills, powders, or potions. If you are looking for the best sleep of your life or to end sleep disruptions, we have 14 recommendations to help you achieve that. In the meantime, try magnesium glycinate or magnesium-rich foods daily to improve anxiety symptoms and sleeping problems.
