Magnesium & The Vagus Nerve

Magnesium & The Vagus Nerve

The vagus nerve is the 10th cranial nerve, extending from the brain through the cervical spine, heart, lungs, and gastrointestinal system. It is the longest cranial nerve and impacts many different organs. It is the control centre of the parasympathetic nervous system, which activates our rest and digest state — the state from which we achieve optimal health and wellbeing.


The vagus is responsible for transmitting instructions from our brain to many organs in the body including the heart, lungs, stomach, and intestines. It can also receive signals from these organs and transmit that information back to the brain. The vagus nerve is very sensitive to stress, and long periods of physical, mental, or emotional stress can impact its function. 

Here are all the ways magnesium can help the vegus nerve and how you can benefit: 

1. Muscle and Nerve Function: Magnesium is involved in muscle and nerve function throughout the body, including the vagus nerve. It helps regulate the contraction and relaxation of muscles, including those in the respiratory and digestive systems, which are influenced by the vagus nerve's activity.

2. Relaxation and Stress Reduction: Magnesium has been linked to stress reduction and relaxation. Adequate magnesium levels in the body can help reduce the release of stress hormones like cortisol. High stress levels can negatively affect the vagus nerve's function, so magnesium's calming effects may indirectly support vagal tone, which is the measure of the vagus nerve's activity.

3. Cardiovascular Function: The vagus nerve plays a role in regulating heart rate. Magnesium is involved in maintaining a steady heartbeat by influencing the electrical impulses that control the heart's rhythm. A deficiency in magnesium could potentially lead to irregular heartbeats, which may indirectly affect vagal function.

4. Anti-inflammatory Effects: Chronic inflammation can negatively impact the vagus nerve's activity. Magnesium has anti-inflammatory properties and may help reduce inflammation in the body. By mitigating inflammation, magnesium could indirectly support the vagus nerve's function.

5. GABA Production: Magnesium plays a role in the activation of GABA (gamma-aminobutyric acid) receptors in the brain. GABA is an inhibitory neurotransmitter that helps calm the nervous system. A balanced GABA system may contribute to a healthy autonomic nervous system, including the vagus nerve.
