Have you ever wondered how the Sleepy Girl Mocktail and Epsom bath salts relate to restful nights? Both are believed to facilitate peaceful slumber, and they share a common ingredient: magnesium, known as a ‘super mineral.’
Magnesium supplements have surged in popularity, often hailed as the latest wellness sensation. As a nutritionist, I can confirm that magnesium is a vital mineral our bodies require daily. It’s involved in over 300 functions within the body, including supporting bone health, muscle and nerve function, stress management, and heart rhythm, as well as enhancing sleep and relaxation. It contributes to these benefits by soothing the nervous system, relaxing muscles, potentially regulating melatonin, and helping to manage stress.

Research suggests that magnesium can indeed enhance sleep quality. One notable study, a randomized, placebo-controlled trial with UK adults aged 18-65 experiencing poor sleep, demonstrated measurable improvements in sleep quality, mood, and related health indicators in those taking magnesium compared to the placebo group. While these findings are promising, it’s essential to conduct further long-term clinical trials with diverse populations to substantiate these results.
The landscape of magnesium can be complex, as multiple forms exist, each impacting the body differently. Some target digestion, others boost energy or muscle function, while some specifically aid sleep. Therefore, it’s crucial to choose the appropriate type for your circumstances. Epsom salts, commonly used in baths for muscle relaxation (magnesium sulfate), may be soothing, but evidence regarding their transdermal absorption and efficacy in treating deficiency is limited.
Below are various types of magnesium suited for different sleep challenges.
Sleep Challenge: Stress and a Racing Mind Before Bed
Recommended Supplement: Magnesium Glycinate
Expert Insight: Stress frequently disrupts sleep, and it can be incredibly frustrating when your mind races with thoughts. Magnesium glycinate contains glycine, an amino acid with calming properties. This form of magnesium plays a role in regulating GABA (a calming neurotransmitter), which may lower stress and anxiety levels. A typical dosage of 150-300 mg of elemental magnesium taken 1-2 hours before bedtime is generally advised, with some studies suggesting faster sleep onset. However, results can vary, and additional research is warranted in this area.
Sleep Challenge: Difficulty Falling Asleep
Recommended Supplement: Magnesium L-Threonate
Expert Insight: If you struggle to fall asleep, it may be due to imbalances in melatonin, GABA, and nervous system activation. Magnesium L-Threonate is a type known for crossing the blood-brain barrier and supporting the nervous system. Higher magnesium levels in the brain could promote deep sleep and heightened tranquility. This supplement is available in both powder and capsule forms, with a common dose of about 1 g taken in the evening. A recent study indicated that Mg L-Threonate enhanced sleep quality, facilitating deeper sleep stages and improved daytime function .
Sleep Challenge: Restlessness
Recommended Supplement: Magnesium Glycinate
Expert Insight: Many people experience restlessness at night, such as tossing and turning. This may stem from neuromuscular excitability or minor magnesium and calcium imbalances. Magnesium glycinate can help calm the nervous system, promoting the parasympathetic nervous system (rest and digest) and reducing nighttime restlessness. A dose between 150-300 mg in the evening is typically recommended.
Sleep Challenge: Waking Up During the Night
Recommended Supplement: Magnesium Glycinate or L-Threonate
Expert Insight: Frequent awakenings during the night can result in exhaustion due to insufficient high-quality deep sleep. Magnesium’s influence on GABA, melatonin, and the nervous system may help diminish nighttime awakenings, particularly for individuals with low magnesium levels. Research indicates that a dose of 150-300 mg taken one hour before bed can help promote faster sleep onset, although there is still inconsistent evidence regarding overall sleep duration.
Should You Consider a Magnesium Supplement?
Many individuals are lacking magnesium, often due to diets rich in ultra-processed foods, soil depletion, food processing, or elevated stress levels. National nutrition surveys indicate that many are not consuming enough magnesium-rich foods. As a nutritionist, I advocate for a food-first strategy. Foods such as nuts and seeds (like almonds and pumpkin seeds), leafy greens (such as spinach and broccoli), whole grains, legumes, cereals, bananas, dates, and even dark chocolate are excellent sources.
Can Magnesium Truly Enhance Your Sleep?
There is no one-size-fits-all solution to sleep, not even with magnesium. Achieving better rest typically involves a combination of balanced nutrition, consistent routines, stress management, and healthy lifestyle choices.
Begin by evaluating your diet to see if you regularly consume magnesium-rich foods. If not, simply improving your nutrition may suffice. However, if sleep issues continue, trying a magnesium supplement might be beneficial, albeit without assurance of its effectiveness.
If you experience severe insomnia, sleep apnea, or significant hormonal or thyroid issues, magnesium alone will not resolve your problems, and consulting a healthcare professional is advisable.
While social media abounds with claims about magnesium as a cure-all for sleep, its effectiveness is still debated. It could be beneficial for those deficient in it, but the evidence remains inconclusive, necessitating more research, particularly within the UK context. Thus, the final verdict is still pending.
Though generally safe for healthy adults, magnesium may not be suitable for individuals with certain health conditions, such as kidney disease, and should be taken under professional supervision.
