Magnesium, an essential mineral involved in over 300 biochemical reactions, plays a crucial role in brain function and neurotransmitter regulation [4]. Many adults experience magnesium deficiency, which is linked to increased risk of anxiety, fatigue, stress, and mental health issues like depression and insomnia [1] [2] [7]. Interestingly, research suggests that magnesium supplementation may help relieve symptoms of mild anxiety, generalized anxiety, and premenstrual syndrome (PMS) anxiety [7].
You’ll explore how magnesium affects anxiety, the various forms of magnesium for anxiety (like magnesium glycinate), recommended dosages, dietary sources (such as nuts, seeds, and legumes), potential side effects, complementary approaches like exercise, meditation, and therapy, as well as consulting healthcare professionals and future research directions [7]. By understanding magnesium’s role, you can make informed choices about incorporating it alongside medications or other strategies to manage anxiety and promote overall well-being.
How Magnesium Affects Anxiety
Magnesium plays a vital role in regulating anxiety levels through various mechanisms:
- Regulating Cortisol Levels: Magnesium helps manage the body’s stress response system and cortisol levels. Low magnesium levels can increase stress, while high stress can deplete magnesium levels, creating a vicious cycle [11]. By maintaining optimal magnesium levels, anxiety and stress can be better controlled [3].
- Balancing Neurotransmitters: Magnesium is essential for the proper functioning of neurotransmitters in the brain, such as serotonin, dopamine, and GABA [12]. It helps produce enzymes that create these neurotransmitters, which are crucial for regulating mood, sleep, and overall well-being [12]. Magnesium may have a calming effect on the body by inhibiting over-excitation of the brain and regulating neurotransmitter levels [12].
- Addressing Potential Deficiency: Magnesium deficiency is common, affecting around 70% of Americans [3]. This deficiency has been linked to increased risk of anxiety, fatigue, stress, and other mental health issues [1] [2] [7]. Supplementing with magnesium may help alleviate symptoms of mild anxiety in individuals with a deficiency [3].
Several studies have examined the effects of magnesium supplementation on subjective anxiety and stress:
- In mildly anxious samples, 4 out of 8 studies reported positive effects of magnesium supplementation (192-300 mg) on reducing anxiety [4].
- In premenstrual syndrome (PMS) samples, 4 out of 7 studies found that magnesium (200-360 mg) helped alleviate anxiety-related PMS symptoms [4].
- A 2017 review of 18 studies concluded that magnesium supplementation did reduce anxiety, including mild anxiety, anxiety during PMS, postpartum anxiety, and generalized anxiety [5].
However, it’s important to note that some studies have reported mixed results, and more research is needed to establish the optimal use of magnesium as a potential therapeutic agent for anxiety [6].
Forms of Magnesium for Anxiety
There are several forms of magnesium supplements that may be beneficial for managing anxiety. The most effective forms appear to be:
- Magnesium Taurate: This form contains the amino acid taurine, which has a calming and neuroprotective effect. It also helps magnesium cross the blood-brain barrier, making it more bioavailable [2].
- Magnesium Threonate: This form has good evidence for improving brain magnesium levels, but may require higher doses [2].
- Magnesium Glycinate: This form contains the amino acid glycine, which has beneficial effects on sleep and brain function [2].
- Magnesium Malate: Well-absorbed and may be helpful for conditions like fibromyalgia and chronic fatigue [2].
Other well-absorbed forms that may help replenish low magnesium levels, which can contribute to anxiety, include:
- Magnesium citrate
- Magnesium chloride
- Magnesium lactate [9]
Some less bioavailable forms, such as magnesium oxide and magnesium sulfate, may still be useful for specific purposes:
| Form | Bioavailability | Potential Benefits |
|---|---|---|
| Magnesium Oxide | Less bioavailable | May help with headaches and constipation, but can cause diarrhea [10] |
| Magnesium Sulfate | Less bioavailable | Can treat low magnesium levels, constipation, and prevent seizures [10] |
While magnesium lactate and magnesium oxide have been commonly used in studies on anxiety, it’s not clear which type is most effective [5]. However, the best types of magnesium for anxiety appear to be magnesium taurate, magnesium glycinate, magnesium lactate, and magnesium oxide [13]. Magnesium taurate is considered the most bioavailable form [7].
Recommended Dosage
The recommended dietary allowance (RDA) for magnesium varies based on age and gender. For adult men, the RDA is 400-420 mg per day, while for adult women, it is 310-320 mg per day [1] [3] [7] [14]. However, the optimal dosage for managing anxiety may differ from the general RDA.
Studies investigating the use of magnesium supplements for reducing anxiety symptoms have typically used dosages ranging from 75-360 mg per day [5]. It’s important to note that psychiatric patients or individuals with severe magnesium deficiency may require higher doses, such as 1800 mg of magnesium threonate [2].
When considering magnesium supplementation, it’s advisable to start with a lower dose, around 100 mg, and gradually increase as needed [15]. This approach helps minimize potential side effects like diarrhea or laxative effects, which can occur with higher doses. Additionally, it’s crucial to consult a healthcare professional to determine the appropriate dosage based on individual needs, as nearly half of Americans get less than the recommended levels of magnesium (300-400 mg per day) from their diets [12].
| Age Group | Recommended Dietary Allowance (RDA) |
|---|---|
| Infants | 30 mg |
| Children | 80-240 mg |
| Adults | 310-420 mg |
While the RDA provides general guidelines, the optimal magnesium dosage for anxiety management may vary, and it’s essential to consult a healthcare provider to determine the right dosage for your specific needs [5].
Dietary Sources of Magnesium
You can find magnesium in a variety of foods, including leafy greens, legumes, nuts, seeds, and whole grains [8]. Some magnesium-rich foods to incorporate into your diet are:
- Dark chocolate, avocados, nuts (almonds, cashews), legumes (lentils, beans), tofu, seeds (flax, pumpkin), whole grains (buckwheat), fatty fish (salmon), bananas, and leafy greens (spinach) [16].
- Pumpkin seed kernels, almonds, spinach, cashews, peanuts, shredded wheat cereal, soymilk, black beans, edamame, dark chocolate, peanut butter, whole wheat bread, avocado, baked potato, brown rice, and plain low-fat yogurt [14].
Eating a balanced diet that includes these magnesium-rich foods can help raise your magnesium levels quickly [16]. However, it’s important to note that leafy greens are considered the best food sources of magnesium, as grains, seeds, and nuts contain phytic acid, which can reduce magnesium absorption [2].
| Magnesium-Rich Foods | Magnesium Content (mg per serving) |
|---|---|
| Pumpkin seed kernels (1/4 cup) | 191 |
| Spinach, boiled (1/2 cup) | 78 |
| Cashews (1 oz) | 74 |
| Peanuts (1/4 cup) | 63 |
| Black beans, cooked (1/2 cup) | 60 |
| Edamame, boiled (1/2 cup) | 50 |
| Peanut butter (2 tbsp) | 49 |
| Avocado (1/2 fruit) | 29 |
By incorporating these magnesium-rich foods into your diet, you can help ensure that you’re getting adequate amounts of this essential mineral, which may aid in managing anxiety [16] [14] [8] [2].
Potential Side Effects
While magnesium is generally well-tolerated and safe when taken in recommended dosages, excessive intake can lead to potential side effects. Here are some common side effects to be aware of:
- Gastrointestinal Issues: High doses of magnesium supplements, particularly magnesium oxide, can cause diarrhea, nausea, vomiting, and abdominal cramping [10] [5] [13]. Taking supplements with meals can help minimize these gastrointestinal issues [13].
- Low Blood Pressure: Consuming large amounts of magnesium supplements (over 350 mg per day) may lead to low blood pressure or hypotension [5] [13].
- Lethargy and Weakness: Excessive magnesium intake can cause lethargy, muscle weakness, and fatigue [5] [14].
- Magnesium Toxicity: While rare, ingesting extremely high doses of magnesium (over 5,000 mg per day) can result in magnesium toxicity, which can be life-threatening [1]. Symptoms may include:
It’s important to note that these side effects are typically associated with excessive magnesium intake and are less likely to occur when following the recommended dosages [5] [13]. If you experience any adverse effects, it’s advisable to consult a healthcare professional and adjust your magnesium intake accordingly.
Complementary Approaches
Combining magnesium with other healthy coping strategies can amplify its effectiveness for managing anxiety. Here are some complementary approaches that can work synergistically with magnesium supplementation [1]:
- Exercise: Regular physical activity helps reduce stress and anxiety by releasing endorphins and promoting better sleep. Combining magnesium with exercise can provide a dual benefit for anxiety management.
- Breathing Exercises: Techniques like deep breathing, meditation, and yoga can help calm the mind and reduce anxiety symptoms. Magnesium may enhance the relaxation effects of these practices by regulating neurotransmitter levels.
- Social Support: Having a strong social network and seeking support from loved ones can significantly alleviate anxiety. Magnesium may help regulate mood and emotional well-being, complementing the positive effects of social connections.
Additionally, while more research is needed, magnesium L-threonate may support brain health and potentially aid in the treatment of disorders like depression and age-related memory loss [9]. Beyond its potential benefits for anxiety, magnesium may also help with other conditions, such as:
- Constipation
- Sleep issues
- High blood pressure
- Migraines
- Diabetes risk [7]
By incorporating magnesium into a holistic approach that includes exercise, stress management techniques, and a balanced diet, you may experience enhanced benefits for managing anxiety and promoting overall well-being.

While magnesium supplements may be beneficial for moderate, generalized anxiety, they are not recommended as a first-line treatment for severe or acute anxiety [13]. In those cases, consulting a doctor is advised to receive appropriate medical care and guidance.
Research and Future Directions
The existing evidence on the potential benefits of magnesium supplementation for anxiety is promising but limited. Several studies have reported positive effects of magnesium on subjective anxiety outcomes, particularly in anxiety-prone populations like those with mild anxiety or premenstrual syndrome (PMS). However, the quality of the evidence is generally poor, with many studies lacking proper placebo controls, adequate statistical analyses, or validated measures of subjective stress [4].
In a review of 18 studies examining the effects of magnesium on subjective anxiety and stress:
- For mild anxiety samples: 4 out of 8 studies reported positive effects of magnesium on reducing anxiety symptoms [4].
- For premenstrual syndrome (PMS) samples: 4 out of 7 studies found that magnesium helped alleviate anxiety-related PMS symptoms [4].
However, the review also highlighted several limitations in the existing research:
- Significant placebo effects were observed, highlighting the need for appropriate placebo controls [4].
- Some studies lacked placebo controls or used inadequate statistical analyses [4].
- No studies administered a validated measure of subjective stress as an outcome [4].
| Study Sample | Positive Effects Reported | Limitations |
|---|---|---|
| Mild Anxiety | 4 out of 8 studies | Lack of placebo controls, inadequate statistical analyses |
| PMS | 4 out of 7 studies | Significant placebo effects, methodological limitations |
While these findings suggest a potential beneficial effect of magnesium on subjective anxiety, the overall quality of evidence is poor. Well-designed, randomized controlled trials with appropriate placebo controls and validated outcome measures are needed to confirm the efficacy of magnesium supplementation for anxiety [4] [6].
Additionally, more research is required to determine optimal dosages, forms of magnesium, and whether magnesium is most helpful for individuals with deficiencies [12]. Some studies have also explored the potential usefulness of magnesium in other neurological and psychiatric disorders, such as depression, ADHD, and autism spectrum disorder, but the results are not conclusive [6].
Overall, while magnesium may offer modest benefits for mild anxiety, it does not appear to be an effective treatment for severe anxiety disorders or insomnia based on current research [15]. Further high-quality studies are necessary to establish the role of magnesium in managing anxiety and other mental health conditions.
Conclusion
