The vagus nerve forms a bi-directional “super-highway” between your brain and the majority of your internal organs. Unless your vagus nerve is in good shape and activates readily when it is supposed to, the communication between your brain and the body will be disrupted.

This modern world can lead to overstimulation of the nervous system and you can become desensitized to chronic stress. Over time, this can lead to low vagal tone, which has been linked to a variety of mental and physical health issues, including chronic inflammation, poor gut function, neurodegeneration, autoimmunity and cancer.

And we know this to be true: you cannot FULLY heal leaky gut, microbiome function or brain issues WITHOUT optimizing your vagus function.

Host of the Mind, Body & The Vagus Nerve Connection Summit, Eva Detko, PhD, MSc, BA (Hons), mIAHT, shares the above wisdom about the vagus nerve. I’ll add this: this overstimulation of the nervous system is especially high right now during this coronavirus pandemic.

In my interview, Balancing Neurotransmitters to Optimize Vagus Function, we start with a review paper that reports how the vagus nerve is intricately connected with anxiety and mood (and immunity).

I share from Vagus Nerve as Modulator of the Brain–Gut Axis in Psychiatric and Inflammatory Disorders:

The vagus nerve represents the main component of the parasympathetic nervous system, which oversees a vast array of crucial bodily functions, including control of mood, immune response, digestion, and heart rate.
It establishes one of the connections between the brain and the gastrointestinal tract and sends information about the state of the inner organs to the brain via afferent fibers.

The review article goes on to state how the vagus nerve is an attractive tool for treating psychiatric and gastrointestinal disorders: “There is preliminary evidence that vagus nerve stimulation is a promising add-on treatment for treatment-refractory depression, posttraumatic stress disorder, and inflammatory bowel disease.”

And as we all know when we hear the term treatment-refractory depression, it means we haven’t got to the root cause of it. It just means that medications haven’t worked for it.

So this allows us to extrapolate and say, well, there’s other lifestyle and dietary, and nutritional approaches that we could use. But they’re saying that stimulating the vagus nerve, activating it, can actually help in this area. And with my work in anxiety, whenever I see depression, I feel like I can replace that with anxiety (because of similar underlying causes). The other thing that they say is that there’s this impact on inflammation: “Treatments that target the vagus nerve increase the vagal tone and inhibit cytokine production.”

And we know that when we’ve got inflammation going on in the body, that’s going to contribute to mood disorders: “Stimulation of vagal efferent fibers in the gut influences neurotransmitters (like serotonin and dopamine, and GABA) that play a crucial role in major psychiatric disorders.”

So the conclusion is that vagal tone is correlated with the capacity to regulate stress responses and can be influenced by breathing. Its increase through meditation and yoga is likely to contribute to resilience, and the mitigation of mood and anxiety symptoms. And we know from other research, and we know from just doing it, that using meditation and yoga is going to affect anxiety levels. We’ve seen research showing that yoga and meditation raises GABA levels, which is one of the neurotransmitters that helps us feel calm. But now we’re also seeing from the research that good vagal tone has an impact as well.

So it’s really exciting to see that there’s many different ways that we can use to approach someone who does have anxiety issues.

I also talk about a very interesting study that brings the connections between GABA and the vagus nerve together very nicely. As I’m talking I see Eva nodding in agreement as I cover this. I wanted to share this study to add another mechanism as to how GABA may work, given so many people don’t believe it can because of the blood brain barrier.

This was an animal study done in 2011 and it’s titled: Ingestion of Lactobacillus Strain Regulates Emotional Behavior and Central GABA Receptor Expression in a Mouse via the Vagus Nerve. You may have had other people in the summit talking about this. I can see you nodding there. Let me just bring it back to this discussion because I’ve got something to add about this. But what they found is this – Lactobacillus rhamnosus increased GABA in the hippocampus. It reduced cortisol levels, which was caused by the increased stress, and it reduced anxiety and the depression in the animals.

When they severed the vagus nerve in some of the mice in the study they found that these neurochemical and behavioral effects were not found. So as soon as the vagus nerve was severed, the effects of the Lactobacillus rhamnosus, which was increasing GABA levels, was not reducing the anxiety and it was not reducing those cortisone levels.

The biggest question that I get about GABA is: “How could GABA possibly work if it can’t cross the blood brain barrier?” Maybe this is one way that is having an impact on anxiety. We know that we’ve got a lot of GABA receptors in our peripheral tissue. We’ve got GABA receptors in our muscles, which probably is the reason why we feel it when we’ve got this physical tension, or we’ve got the spasms. We’ve got GABA receptors in our pancreas. We’ve got GABA receptors in our endocrine system.

But maybe this vagus nerve connection and the fact that when it’s severed we’re not getting those effects, maybe this is another way that GABA is having an impact on anxiety.

Making the vagus nerve connection to serotonin, I share some interesting new research on SSRIs and the vagus nerve, and my favorite vagus nerve exercises. One of them – social interaction – has been challenging lately but cold showers are very do-able.

I also share how I use GABA and tryptophan with clients so if you’re new to this you’ll learn more about this in that section.

As you know, my work is primarily using the neurotransmitters precursors (such as the amino acids) and using dietary changes, but we don’t want to forget about other approaches like vagus nerve support.

If we can improve a vagus function, then we’re going to get even better benefits.

I don’t go into the immune connection in my interview because it was recorded before the coronavirus pandemic started but keep this in mind as you tune in: you cannot have a well-functioning immune system without a healthy nervous system, and vice-versa!

Dr. David Jockers, is interviewed on the topic of the ketogenic diet on the Mental Wellness Summit 2, which airs online September 25 – October 2, 2017. The title of his interview is “Ketogenesis for Energy Stability” but I feel it could be called “Ketogenesis for Energy, Mood Stability and an end to Anxiety.” It’s a brilliant interview and he starts by sharing how the brain can use ketones and not only sugar:

We know that about 2/3 of the brain energy can be produced by ketones. We used to think that basically the brain depended upon sugar as its only energy source. And it does need a small amount of sugar, and that’s why it’s so important we have to have a certain level of blood glucose. However, as we get keto-adapted, when we start to utilize ketones as an energy source, the brain gets much more effective and efficient, and it needs less of the sugar.

And that’s important because sugar produces a lot more metabolic waste. And so when the brain is using ketones, there is going to be less free radical damage and what we call oxidative stress in the brain, so less damage being associated with the various neurons in the brain therefore better connection, better communication.

He shares that ketones are epigenetic influencers and improve neuron sensitivity thereby improving neurotransmitter production:

Ketones act to induce healthy genetic expression. They’re epigenetic influencers where they actually influence the brain to promote more BDNF (brain derived neurotrophic growth factor), which helps grow more neurons and more synapses (little gaps between the neurons). They help produce more neurotransmitters and really optimize the expression of these neurotransmitters to where we get good sensitivity between the neurons.

So when the neurons secrete serotonin, the next neuron is able to actually connect with that very easily and realize “hey, this is the message that we need to get across.”

Dr. Jockers then goes into the relationship between GABA and glutamate and how the ketogenic diet improves the ability of glutamate converting into GABA:

There is a relationship between glutamate, which is an excitatory neurotransmitter in the brain, and GABA, which is an inhibitory neurotransmitter. Glutamate naturally converts into GABA when certain nutrients are present – like magnesium and vitamin B6 – along with a properly working GAD enzyme.

Now, when we have ketones present, they have been shown to improve the ability to convert glutamate into GABA.

Individuals with anxiety or obsessive compulsive [disorder] often have excessive amounts of glutamate, which can cause too much excitation in the brain and something called excitotoxicity that damages a whole bunch of different neurons, and causes massive neuronal death in parts of the brain. It can lead to symptoms like anxiety, headaches, migraines and seizures. The ketogenic diet has been shown in many studies to be a very powerful remedy for seizure disorders like epilepsy. That’s where this neuropharmacology of the ketogenic diet was analyzed in detail where they came up with the understanding that it impacts this glutamate to GABA conversion.

When we have adequate amounts of GABA and this proper relationship of glutamate to GABA, we feel very emotionally balanced and calm. We are able to fall asleep well. We have less pain in our body, and less susceptibility to headaches. In general, we just feel very emotionally balanced, and that’s what we’re going for.

Ketones are a huge help when it comes to that. When you’re in a state of ketosis, your natural feeling should be that you just feel awesome. You feel like a high performer. You feel at peace and you feel calm. That’s a sign that you’re in ketosis. If you are on a low carb ketogenic diet but you’re noticing irritability, anxiety and headaches, you’re actually not using the ketones. Your body is not actually keto-adapted. Instead, you’re in a hypoglycemic mode where your blood sugar is too low. You’re not using the ketones, and you’re getting exitotoxicity in your brain.

He goes on to share what a ketogenic diet should look like:

Avocados, coconut oil, coconut butter, coconut flakes, coconut milk, grass-fed butter, so butter or ghee (which is clarified butter from grass-fed cows) olives, olive oil. You want at least one of those in every single meal and you want a lot of it in every single meal.

Dr. Jockers shares about how much protein to eat, what proteins to eat, what fruits and vegetables and how much to eat, how he cycles in and out of ketosis, how he uses intermittent fasting, his favorite supplements to support ketosis (magnesium threonate is one of them), his favorite adrenal adaptogens and much more.

I hope you can us join on The Mental Wellness Summit 2 summit to hear Dr. Jockers and other excellent speakers.

I know they are referring to medications but I find it quite funny that the hosts say the “magic pill” solution is not the answer. As you’ll hear in my interview, the dangers of benzodiazepines and why GABA is a more effective option for anxiety, I believe that GABA (and tryptophan and the other amino acids) are truly “magic pill” solutions that help so many seeking relief while they dig deeper for other contributing root causes and start to make dietary changes, whether it’s switching to real whole foods, quitting gluten, removing all grains or implementing a ketogenic diet.
