What Is the Vagus Nerve?
The vagus nerve is the 10th cranial nerve and is one of the longest and most complex nerves in the body. It’s the main nerve of our parasympathetic nervous system, which means its function is to calm us down and help us unwind. Some of the functions the vagus nerve modulates are:
- blood pressure and heart rate
- digestive processes such as gastric secretion and peristalsis
- respiratory functions, including breathing depth and breathing rate
- immune system responses and inflammation
- stress and anxiety reduction
- rest, relaxation, and sleep quality
Lion’s Mane Effects on the Vagus Nerve
Unfortunately, there is no research on the effects of lion’s mane on the vagus nerve, in particular.
But lion's mane seems to be good for nerve growth and regeneration, so it's safe to assume that this mushroom may help the vagus nerve work better.
Let’s take a look at how lion’s mane can aid in nerve growth and regeneration, as well as how it may improve some vagus nerve functions.
Does Lion’s Mane Heal Nerves?
Lion’s mane appears to aid in peripheral nerve regeneration, at least in animals. An animal study examined the effects of lion’s mane extract made of fresh fruit bodies on peroneal nerve injuries in rats. Results show that lion’s mane mushrooms stimulate nerve regeneration after peripheral crush injury.
Another study, published in 2012, examined the underlying mechanisms of lion’s mane’s ability to regenerate nerves. According to this study, lion’s mane activates MAPK signaling pathways, which are involved in mediating neurite outgrowth and regeneration.
Can Lion’s Mane Promote Nerve Growth?
Lion’s mane is one of the most potent neurotrophic supplements, and research shows that it can improve nerve growth.
A 2014 study examined the mechanisms behind the neurite outgrowth stimulatory effects of Hericium erinaceus. According to this study, lion’s mane stimulated nerve growth factors by activating signaling pathways involved in neurogenesis (MEK/ERK and PI3K-Akt pathways).
A recent study published by the University of Queensland Brain Institute discovered that "the lion's mane mushroom had a significant impact on the growth of brain cells," confirming prior research that these mushrooms enhance memory by stimulating nerve growth.
Many more studies examine the benefits of lion’s mane on nerve growth. Read our article on lion’s mane and neurogenesis to learn more about this amazing benefit.
Can Lion’s Mane Improve Digestion?
Research shows that there is a link between digestive issues, such as excess gut microbiota, and poor vagus nerve functioning. Through its beneficial effects on gut health, lion’s mane may alleviate these issues, and thus help your vagus nerve run smoothly.
In a 2017 animal study, researchers looked at the effects of Hericium erinaceus on inflammatory bowel syndrome (IBS) in rats. The results showed a significant improvement in histology results in rats with IBS after two weeks of treatment, indicating that lion’s mane reduced symptoms of IBS.

FAQ on Lion’s Mane and the Vagus Nerve
What supplements heal the vagus nerve?
If you want to heal your vagus nerve, supplements containing adaptogens such as Hericium erinaceus, Lignosus rhinocerotis, and Cordyceps militaris are a safe choice. Supplements that contain choline, B12, and magnesium can also aid in vagus nerve healing.
Does lion’s mane affect GABA?
Lion’s mane may stabilize GABA levels in the brain thanks to its beneficial effects on neurotransmitter production. GABA is the primary inhibitory neurotransmitter in the brain, and low levels of GABA have been associated with increased anxiety and stress levels.
How can I fix my vagus nerve naturally?
There are many ways to influence your vagus nerve toward health, but you have to be persistent in order to see improvement. Some people use adaptogens or herbal remedies such as chamomile tea and matcha.
Others use foods like spinach, nuts, seeds, and bananas also aid in vagus nerve repair. Many have found benefit in meditative practices. Here’s a list of common ways people work on improving their vagus nerve naturally.
- Deep breathing. Practice slow, deep breaths to activate the vagus and promote relaxation.
- Cold exposure. Embrace the chill! Cold showers, cold water plunges, or even splashing icy water on your face can boost vagus nerve function.
- Gargling. A daily gargling session engages throat muscles, which in turn stimulates the vagus.
- Singing or humming. Serenade your VN by singing, humming, or chanting to activate its functions.
- Probiotics. Feed your gut with probiotics found in fermented foods like yogurt and sauerkraut to support VN function.
- Omega-3 fatty acids. Consume fish like salmon and plant sources such as walnuts and flaxseeds for their VN-boosting omega-3 fatty acids.
- Socializing. Engage in positive social interactions, which activate the vagus nerve and improve overall well-being.
- Yoga and meditation. Practice yoga and meditation to calm the sympathetic nervous system and bring the parasympathetic nervous system more online.
- Nutrients and adaptogens. Incorporate nutrients such as B vitamins and magnesium into your diet, as they play a role in nerve function. Adaptogens like cordyceps, ashwagandha, lion’s mane, and Rhodiola rosea may also support the vagus nerve by helping your body adapt to stress.
By integrating these methods into your daily routine, you'll be on your way to enhancing your vagus nerve function naturally. Enjoy the journey as you hum a tune, socialize with friends, and savor nutrient-rich foods that support your parasympathetic nervous system.
What is the best vitamin for the vagus nerve?
