Science-Based Health Benefits of Magnesium

Science-Based Health Benefits of Magnesium

Magnesium is an essential nutrient that is required for many different biological processes including energy metabolism, DNA production, cell communication, brain function and more.

Almost 50% of the US population may be deficient in magnesium.1

Magnesium is included in Magnesium Complex by Beyond Vita®. 

1. Mood and Depression

Magnesium is critical for brain function and low levels have been associated with depression and researchers claim it may be useful in the management of depression.2,3

Researchers claim that case studies in magnesium deficiency show magnesium supplementation can lead to a recovery from major depression in less than 7 days.4

In a randomized trial of adults with low levels of magnesium, researchers reported that magnesium supplementation was as effective as an antidepressant in alleviating depression.5

Magnesium may help improve mood and reduce depression.

2. Helps Lower Blood Sugar

Low magnesium intake has been associated with developing type 2 diabetes in a meta-analysis of 13 studies involving 536,318 participants.6

A 2014 study concluded that magnesium intake may be beneficial in reducing the risk of developing diabetes.7

In a randomized double-blind controlled trial, researchers found that magnesium decreased fasting blood sugar levels by 22.3% and HbA1c by 20.8% compared to the placebo group.8

Multiple other studies also found that magnesium can lower fasting blood glucose levels.9,10,11

Magnesium may help lower blood sugar levels.

3. Helps Reduce Headaches

Low levels of magnesium have been linked to persistent headaches or migraines.12 Another study claims magnesium deficiency may be present in up to 50% of migraine suffers.13

In a randomized double-blind placebo-controlled study, researchers concluded that magnesium is beneficial for the prevention of migraines.13

In a review of 5 clinical trials, researchers found magnesium supplementation may possibly be effective in the prevention of migraines.14

Magnesium may help reduce the occurrence of headaches.

4. Heart Health

Magnesium deficiency has been associated with increased levels of C-reative protein which is a marker for chronic inflammation that has been associated with atherosclerosis and cardiovascular issues.15,16

Researchers have found that magnesium supplementation can decrease high C-reactive protein levels in multiple studies.17,18

A 2009 randomized double-blind placebo-controlled trial found that magnesium significantly reduced both systolic and diastolic blood pressure.19

A normal level of magnesium has been associated with a 30% lower risk of cardiovascular disease.20

Additionally, a magnesium deficient diet is linked to a hardening of the arteries or coronary artery calcification.21

Magnesium may help improve heart health and reduce the risk of cardiovascular issues.

5. Premenstrual Syndrome

In a randomized double-blind trial involving 32 women with premenstrual syndrome (PMS), researchers found that magnesium supplementation significantly reduced the negative mood effects of PMS.22

Another study demonstrated that magnesium supplementation also reduced mild fluid retention in women with PMS.23

Additionally, magnesium may help reduce menstrual migraines.24

Magnesium may help improve premenstrual syndrome symptoms.

6. Helps Improve Sleep

In a double-blind and placebo-controlled clinical trial, magnesium supplementation was able to significantly increase sleep duration, decrease the time it takes to fall asleep, increase sleep quality and reduce early awakenings. Magnesium also increased melatonin production and decreased cortisol which may be why magnesium can positively impact sleep.25

Magnesium may help improve sleep quality and duration.

7. Thyroid Health

Magnesium deficiency was found to be associated with hypothyroidism in a 2018 study.26 Other studies have also demonstrated a reduction in thyroid hormones as a result of magnesium depletion.27,28

Supplemental magnesium may help restore thyroid hormone levels.29,30

Magnesium may help raise thyroid hormone levels and improve thyroid health.

8. Stress and Anxiety

A magnesium deficiency combined with HPA axis dysregulation may contribute to an increase in anxiety.31

Low magnesium levels are also highly associated with increased stress levels.32

In a 2017 clinical trial researchers reported magnesium supplementation was able to significantly improve symptoms of generalized anxiety disorder.33

Another clinical trial involving 264 patients found a 42% reduction in stress based on the DASS-42 stress score over eight weeks.34

Magnesium may help reduce stress and alleviate anxiety.


Magnesium is an essential mineral that may help improve mood, lower blood sugar, improve heart health and more.*
