How to Enhance Your Gut Microbiome for Brain & Overall Health 

This is a lot of information to digest.

Just sharing my notes. I posted this on Medium as well for your convenience (easier to read) Gut-Brain Axis -The gut communicates with the brain and the brain communicates with the gut all the time. They represent a biological circuit. It is bi-directional. -Gut is not just the stomach. It includes the entire digestive tract. -The nervous system includes the brain and the spinal cord, which together make up the central nervous system. The neural retinas are also part of the Central Nervous System. The eyes are the only part of the brain that are outside the cranial vault. -Peripheral nervous system: everything that’s outside the brain, spinal cord and eyes. Digestive system -Begins at mouth and ends in anus. -It’s a tube, and the hollow of the tube is called the lumen. -The microbiota resides all along the lumen. There are little niches where particular things can grow best. -Along the digestive tube there is a lot variation of acidity, which gives rise to different microenvironments in which microbiota can thrive or fail to thrive. -Our own behaviors will adjust the microenvironments in which the microbiota will be more likely to thrive or not. Microbiota -Microbiota: Is the wide variety of microorganisms that live in a certain environment. So the “human microbiota” includes all bacteria, viruses, fungi, and other single-celled organisms living in the human body -They contribute to digestion. They make genes involved with digestion. -What we eat change the enzymes that these bacteria make. -They change the way that our brain functions by metabolizing some neurotransmitters. It is converted into chemicals such as GABA (suppress the action of other neurons. Its principal role is reducing neuronal excitability throughout the nervous system.). -The microbiota highly influences our immune system, brain function and digestion. Microbiome -Microbiome: The collective genomes of the microbes (composed of bacteria, bacteriophage, fungi, protozoa and viruses) that live inside and on the human body. -What we eat strongly influences our microbiome. -But the Microbiome is also made up by things that come inside our body through breathing, thru skin contact, and also thru thoughts and social interactions. -What is a Healthy microbiome? One that includes a lot of diversity. -Probiotics and prebiotics can enhance microbiota diversity… excessive probiotics can lead to brain fog states. Neurons in the Gut -These neurons pay attention to the components of the gut (nutrients and microbiota) and send signals to the brain so that it seeks out more of a particular food. -When we eat something we like, these neurons are activated because certain nutrients in those foods are present (sugar, fatty acids and amino acids). -Neuropod cells: These are gut sensory cells. They provide the foundation for the gut to transduce sensory signals from the intestinal milieu to the brain through fast neurotransmission onto neurons. -They have strong activation to sugars. They communicate via the pathway of the vagus nerve (responsible for the regulation of internal organ functions). When they sense sugar they send signals that trigger activation that cause us to seek more of this particular food. How? It adjusts the release of some neuromodulators (like dopamine). -What we consider the taste of a sweet food has to do with a gut sensation that is below a conscious detection (taste of food and texture are also components that determine this). -Free will & food cravings: Events in our brain are determined by biological events that are below our conscious detection. Ghrelin -Ghrelin is famously known as the “hunger hormone”. It increases with fasting. -When fasting, ghrelin goes up and we tend to be more alert (the body is alert seeking out food). Epinephrine goes up. Glucagon like peptide 1 -GLP1 is made by neurons in the gut and in the brain. Is a hormone produced in the gut and released in response to food. It causes reduced appetite and the release of insulin. -Used to treat type 2 diabetes and to reduce obesity. -Foods that increase GLP1: yerba mate, nuts, avocados, eggs, high fiber complex grains. The ketogenic diet increases GLP1. -GLP1 is another gut-to-brain mechanism that is dependent on diet. Mechanical signaling -When you eat a lot you might get distension of the gut. This distention is signaled and communicated to the brain to suppress the feeding. Also even vomit. Activates the area “vomit center”. -Signals are both to seek more food and also to stop eating. Direct and indirect signaling -Direct signals: neurons in the gut communicating with neurons in the brain. -Dopamine is involved with vomiting. When dopamine is too high it makes us stop eating and even vomiting. -Indirect signals -Neurotransmitters cause the activation of other neurons. The gut microbiota are capable of influencing metabolic events and also of synthesizing neurotransmitters themselves. They make neurochemicals that can impact the body indirectly. The foods you eat, the environment of the gut microbiome can create the substrates that allow the brain to feel one way or the other. -Dopamine can be synthesized by some particular microbiota, which can raise our baselines levels of dopamine (baseline levels act as a level of the tide). -Other microbiota support the production of serotonin. Baseline levels of serotonin set our average mood. 90-95% of serotonin is produced in the gut! -Other microbiota raises GABA levels. -Studies show that creating the correct environment for these microbiota to thrive it enhances mood and wellbeing. Early establishment of gut microbiome. -The environment that we are exposed to (contact with any mucosal lining) in the first three years of life have a profound impact on the overall menu of microbiota that we will be able to carry within our body. Building a diverse microbiome in the first three years is critical. -Cesarean delivered babies have less diverse microbiome. -The more diversity of microbiota that one can create earlier in life is essential. (Breastfed, Exposure to pets, different adults, different rooms and outside play). -If children are exposed to a lot of antibiotic treatment can be very detrimental to develop a healthy gut microbiome. And not even in children. We should be wary of antibiotics. Gut health benefits -Particular types of microbiota (l-reuteri) can offset symptoms of autism (studies in mice) by activating the vagus nerve that stimulates dopamine and oxytocin. -Gut health also reduces obesity and diabetes. -One study showed that microbiota diversity lowers loneliness. Tools and behaviors: DO’s and DON’ts -Stress impacts negatively the gut microbiome. -Fasting: during prolonged fasting there’s thinning of the mucosal lining and a lot of microbiota species can start to die off. So fasting can cause a disruption to certain healthy elements of the gut microbiome. Caveat: When people eat after a period of fast, there is a compensatory proliferation (increase in healthy gut microbiota). -Probiotics: ingestion of probiotics can be useful to increase microbiota diversity (at a fairly low-to-moderate level, we don’t need excessive amounts). But… after using anti biotics or being ill or super stressed, ingesting higher doses of probiotics and prebiotics can be helpful. The bacteria that are present in most probiotics don’t actually replenish the microbiota that we need most. But they make the environment better. Foods to Ingest -Types of food we need to ingest that enhance mood and wellbeing. -Study: they measured the impact of the microbiome health in two groups. One with a high fiber diet, and other with a high fermented foods diet. -Results: High fiber diet did not lead to increased microbiota diversity. But increased number of digestive enzymes. However, a fair amount of fiber is a good idea, don’t neglect it. High fermented food diet increased microbiota diversity and decrease inflammatory signals and activity. -Amount: 4 to 6 servings of fermented foods per day. Serving size: 4-6oz. -What kind of fermented foods? Low-sugar fermented foods. They have to contain live active cultures (microbiota that are alive). -When to eat them? Its going to work best if you spread the servings throughout the day. Not all in one meal. -Examples of low-sugar fermented foods: • Plain yogurt • Kimchi • Sauerkraut • Kefir • Natto • Brine: richness of live cultures -You can make fermented foods yourself to reduce the high costs. Takeaway: Fermented foods are excellent for microbiome health. We should all be trying to incorporate more of these. Artificial sweeteners -Disruption in gut microbiome (Studies only in animals). -Neurons in the gut are capable of distinguishing real sugar and artificial sweeteners.

Sometimes the timing of these podcasts is simply heroic.

Thank you so much Dr. Huberman, I can't sufficiently express how grateful I am to be able to learn from you. I know it may not interest half of your audience, but an episode about women's health-- PCOS, endometriosis, fertility, birth control, menstrual cycles, etc -- would be so amazing!

You are changing and saving my health and day to day life. Anyone else fall asleep listening and then watch 2-3 times more to take notes?

54:25 Bacillus & Serratia (Dopamine) 55:45 Candida, Streptococcus, Enterococcus (Serotonin) 58:15 Lactobacillus (Dopamine) & Bifidobacterium (GABA) 1:04:14 L. Reuteri (Dopamine & Oxytocin)

Never waited for Monday morning like this 🙂Setting up my schedule to listen & take notes. Blissful Monday Morning to Andrew and everyone. stay healthy & Happy

Dr. Huberman, your content is gonna create superhumans! Thanks for everything that you're sharing with us.

I find it cute that he mentions "The more diverse your gut microbiome is, the less lonely you are" cuz it's like your micro bacteria is keeping you company !

Fantastically informative, thank you. Quick Kefir Recipe - 1 litre milk (I use goats milk) 110 grams plain yoghurt (provides bacterial culture) 1 teaspoon sugar (provides a little food for bacteria). Warm milk in large saucepan over low heat to 35-40C. Cool slightly then mix in yoghurt and sugar. Transfer to a sterilised jar and cover with clean tea towel. Keep mixture at room temperature (about 24C) for 5-6 hours then transfer to fridge for further 10-12 hours. Keep 110 grams of this mixture as your new starter, instead of the yoghurt.

This podcast is an absolute godsend. Baffling that this information is readily available for anyone willing to seek it. the most amazing channel I’ve ever come across

This lecture is impressive even without sketches or other visuals. Dr. Huberman is an expert in hand gestures in verbal communication.

Vet student here. It's interesting that you mention how early life plays such a role in determining the gut microbiota of an individual later in life. For cows and sheep, the intake of a mother's colostrum within the first twenty four hours of life, is imperative in determining a calf/lamb's immune status. Any delay, decrease in quality, or failure to receive the IgG antibodies from the colostrum, will render the offspring immunocompromised, termed failure of passive transfer. It would be incredibly interesting to see studies in the future that evaluate the gut microbiota between groups of animals that did/did not receive adequate amounts of colostrum!

Aside from method of birth and who handles the infant the most in the early days, the biggest influence on the seeding of the human micribiome is whether they are fed with human milk or not. Human milk, unlike formula, contains oligosaccharides which feed the gut microbes. It also seals the 'open' gut, preventing large particles from being absorbed and setting off allergic reactions.

This was so informative and I learned so much. You have such a great way of teaching that is very effective. Thanks!

I’m obsessed with these episodes. I can’t stop listening and will probably listen multiple times lol. I found you off the Rogan podcasts and am so thankful. Thank you for all you do!

As someone who struggles with bulimia this is extra fascinating! One of the things that makes it so difficult to get overcome the condition/habit (when you’ve had it for a long time) is how horrible it feels to digest food. I think this is partially due to imbalances in the gut microbiome, low stomach acid, etc. this episode is giving me another lens to understand why I don’t always feel in control of my behavior.

Topic request: How to rest your brain. (Outside of sleeping) Do you need brain rest days? How do you differentiate true brain exhaustion from giving up? And as always thank you for being interested in teaching science. 😁

Excellent! Intermittent fasting is like miracle grow for your body- and brain; thus connecting one’s gut, and brain. Our gut is our second brain.

THIS is the class I have been waiting for. Thanks Doc!

My gut instinct says The Huberman podcast is helping humanity improve. Truly appreciate all your endless efforts Andrew.

I wish only one single trip to the gastroenterologist would be like this, things would change really!

I will never think of “gut feeling” the same way. Great episode on so many levels. Thank you. Not to be dramatic, but we are truly an incredible, complex, and beautiful biological system. I can’t get over it. 💗✨

Starting a 3 day fast this morning. This is perfectly timed food for thought. Thank you!

I would love it if you included information about specific gut bacteria like Akkermansia Mucinophilum etc., which have been shown to modulate immune response against cancer. Im pretty sure there are other microbes as well and the specific interventions we can take towards increasing specific populations would also be helpful. Thank You for your wonderful work sir. Looking forward to the inclusions

Thanks Professor! This is one of my favorite subjects to learn about! Like they said; your GUT is your second 🧠 BRAIN! Can’t wait for the next episode! Be well!🙏🏾

I am ABSOLUTELY in love with listening to your podcast Dr.Andrew! As a new nurse and an aspiring woman who wants to be better overall, your videos just make things click! Thank you!

Andrew, you are exactly what society needs, I have worked hard for years to help people understand their health and good resources are rare. Your natural ability at this is spectacular, and will have far reaching benefits.

Thank you for sharing this fantastic knowledge for free. Your ability to concentrate/focus and remembering is admirable Professor 🙌

When you describe the structure and anatomy of the gut around the beginning of the video, like around 14:00, it would make this already amazing podcast episode even more awesome for the people watching it on RU-vid if you included diagrams or visuals of the anatomy you are describing. Thank you for this awesome podcast!

I've been waiting for Dr. Huberman to tackle this topic. And I'm even more excited to hear there'll be another video on the gut brain connection with an expert next week. Thank you so much Dr. Huberman. You're awesome!!

Awesome information, thanks for this Dr. Huberman!

Have you heard anything about pesticides and organic food. I don't know what to believe anymore when it comes to this anymore. Thanks for all your scientifically informed podcast!!!

Going to stanford in the fall, cant wait to take our neurobiology class!!

Was recently diagnosed adhd and GAD, would love to see Dr Russell Barkley on your show. Both of you have changed my life all for the better. Your forces are sure to bring lots of great information.

Dr. Huberman, thanks a lot for your fascinating topics and episodes. Could you maybe do an episode that will focus on IBS? This condition is too prominent today (it's the main reason people visit gastroenterologists) , and is currently being approached from different angles, probiotics, diets, and hypnosis being some of them. I thought you could be the one to scientifically address this issue in all its complexity. Thanks again for sharing your knowledge with people around the world.

Can you please do an episode with long term covid side effects (including vaccine, if possible) on cardiac, lung and general health. Love your work

I am currently studying the digestive system and it’s anatomy for uni (Herbal medicine/Naturopathy) so the timing of this podcast is sensational! thanks Huberman!

Thank you, Dr Huberman!! We desperately need more research on the enteric nervous system, and are so grateful for the time you have spent on this subject.

One of the best if not the best channel providing very well explained science topics plus with actionable points. A well tuned fountain of high quality information!

Amazing episode, yet again - THANK YOU!!! Our microbiome diversity - or lack of - is correlated to our soil microbiome diversity. The interconnectedness is real. And our diversity is half similar to others, generally speaking, although numbers and communities are unique, overall, to each individual, like a fingerprint . We also have to have healthy epithelial tissue for the probiotics to live on! And sleep/circadian rhythms/SCN and peripheral clocks and microbiome genetic regulation are interrelated! And an important consideration re fermented foods is the histamine content, and mast cell activation. Soo fascinating!

Good morning class!!! Can’t wait for to hear about this……. awesome. Such an important topic . Can’t wait to watch your upcoming conversation with Lex Fridman.

The timing was so good. I'm just suffering from stuff like bloating and constipation and finding ways to deal with it. I'm sure going to watch this podcast.

This is a topic that has fascinated me for a long time, having personally suffered from many digestive issues. Thanks again for sharing this information Dr. Huberman!

Fantastic podcast as usual! I would love to hear a deeper dive into the gut microbiome and it's link to crohns disease. In addition, perhaps alternative methods (helminthic therapy, hyperbaric chamber, targeted vitamins and gfdf, candida diet and fasting (or not) for support). Thank you for your varied podcasts!

For the last 3 weeks i had horrid brain fog and lost my mental clarity but after learning how the gut and brain are connected i managed to fix my brain fog and get back to my usual self. This kind of knowledge on the human body needs to be taught by default at schools from an early age

Huberman is one of the few content creators where I always like his vids before they even get started because it’s always good.

I misjudged your podcast once quite awhile ago, and clicked away immediately after all the commercials.. thinking I may have stumbled onto another Dr. Oz. Having forgotten that, I tuned in again and fairmindedness prevailed ("hear people out," as Mom always said). Sooo glad I did: you give WAAAY more complete, thorough, usable and cutting-edge information than is usually available. Well worth any amount of time spent listening to your ads (which are ALSO helpful and informative, actually). Thanks for your time and generosity in sharing your knowledge and research.

That was amazing! I would love a podcast about women aging and hormones.

Grateful for putting the effort & time to teach science and put it out to the world for free. The topics you are choosing are extraordinary!!!! God bless

Fantastic episode Dr. Huberman! As an osteopathic practitioner I find your podcast to be extremely informative and thought provoking. It expands my knowledge and curiosity, and motivates me to pursue relevant topics that come up in the clinic setting. I always try to listen and view the information you provide through an osteopathic lens. This involves understanding the viscero-somatic and psycho-somatic reflexes, how they interact and manifest as physical and musculoskeletal symptoms; and how I can affect physiology through treatment of anatomy. Thank you for your continued effort and education in science!

Thank you, I am in my early 60s. I haven't finished college, despite the love I have for science. Listening to you always makes me be more fascinated by science. you're amazing!!!

We need Part Two! Also would love to see Inside Tracker’s David Sinclair weigh in on the genetic results that are related to the results and recommendations from their testing (since you support them).

I love this podcast. This was really interesting to dive into. I'm really curious about how this would affect or relate to the fungal diseases. Im referring to the book "The Fungus Link, An Introduction to Fungal Disease" by Doug A. Kaufmann, which collects a variety of testomonies and cases by different doctors in different areas, asserting the impacto of fungi in our health, primarly through nutrition and it even suggests a diet that could promote healthier results. Thanks!

Thank you Dr. Huberman, team, sponsors and supporters ☀️

Thank you Dr. Huberman. I listened and watched a lot of lectures on the subject, but you are the best of them all. I am always amazed at how much the human brain controls us in everything. I liked your recommendation for making a delicious and easy-to-prepare sauerkraut: cut the cabbage into thin strips, salt, a storage vessel with a lid and compress the cabbage to secrete the liquids. Take care of your health. Waiting for the next program.

A sincere thank you to you Dr. Huberman and your team for giving myself and so many others something to look forward to each week. Very excited to consume (pardon the pun) this info!

On Sundays, I liked to listen to Alan Watts. Since I've listened to almost all of his works I feel enlightened enough ;-) Now I found another side of self-understanding and my listening goes to Andrew Huberman. Thank you, Dojo of biological self-awareness.

I loved learning the biochemistry / hormone shifts that happen when fasting, namely that our body releases epinephrine which can lead to agitation. I do my best to intermittent fast, but find it challenging to do with kids around. If I need to be the calm presence that negotiates squabbles or melt-downs or if I'm the main snack maker, it can feel really daunting.

After the first few months of the pandemic I started feeling really anxious and self medicated with lots of junk food and alcohol. I’ve been working on healing my gut for the past few months, cutting back on drinking and switching to half or quarter-caffeinated coffee. The difference is night and day.

Wow! Explains so much. Was hoping for a little more on the sweet taste issue as it relates to diabetes. All but one of my siblings have diabetes, my dad has it and my mother passed away from diabetes complications. Seems like I'm always running from this monster. Thanks again!

Andrew, you have no idea how perfect the timing of this podcast episode is. Good lord. I haven't even started listening yet and I am as excited as can be. I've battled with my gut microbiome for a while now. Starting a new job tomorrow which has me worried about my ever-going stomach issues, mental fog, and bad nutritional uptake. I know a fair bit about the gut microbiome but I'm sure I'm gonna learn so many new things here that will help me. Thank you Andrew for an amazing and comprehensive podcast, and all the scientists who keep doing what they do.

You are the bridge between school knowledge and the current research. Thank you for doing this!

Today I decided that - I’m going to go back to all the videos I’ve watched of yours, & start taking notes because wow!!! Thank you for all of this free info on all these topics. I too enjoy the people you interview. Again , thank you Andrew.

time for priceless education again from excellent Stanford professor people better listen up . this is gold as always and FREE ❤

I’m so glad to hear that fermented foods are more helpful than fiber for gut health because kombucha and yogurt actually do settle my stomach when I feel icky. I feel like fiber increases my bloating which is the last thing I need when I am already bloated and constipated.

Loved the probiotic info...fascinating...thank you Dr. Huberman for the time you take outside of your busy schedule to share this information with the world in such an enjoyable and captivating way.

Nothing better to start my morning listening to this amazing class! 💯

This is the episode I needed for awhile, since I have a bad stomach health as a kid. Hopefully, the many information and advice from the episode can help me to improve my gut health. Thank you for the educational information Dr. Huberman.

Brilliant as always! We really need more of this species of extraordinary science communicators! One suggestion would be to tod an episode or interview and expert on skin microbiota or oropharynx/Nasopharynx microbiota, it’s a much less researched subject seems interesting for diseases like skin cancer.

I been researching dog health for years after loosing dogs to cancer,and I always try to give my dogs fermented foods .Glad to hear this .

Thanks you so much. I,m really enyoing with your podcast. I have done a course about adictions and trauma, and I have recommend your podcast. I said that at this moment I learnt not only about the books or the abstracts I read. I learnt with music, with podcast and I showed your podcast to my psychologists, psyquiatrics and social workers. Now we learnt with lots of stuffs and last year you are been my better teacher. Thank you so much.

I recently listened to your interview with Lex Fridman, how did you know to give Costello testosterone, or how much to give him, etc? Please consider doing an episode on protocols to optimize the health and extend the lives of our animal companions. 😽

Dude i saw a video where you talk about how to enchance natural testostorone levels and it was very informative and those supplements most likely work( Haven't tested them cause of availability in my region) and the second your video i discovered yesterday was about 40 Hz frequency. It works, i even had such intense dreams and i dream very rare. THANK YOU for putting this kind of information out there. Now i am very interested what you have available in your channel. Peace!

I've Loved EVERY episode of your podcast I've ever listened to. But as a person diagnosed with a neurological disorder and dealt with chronic pain and stress -- i've employed the use of fermented foods for years and swear by them. Thus this was my favorite episode yet. Great to learn some of the scientific backing to this. Can't wait for the next epsidode!

I've been waiting for this. I've been reading and learning about this for a few years now and it is extremely interesting. My friends are growing tiresome because I keep trying to inform them about it. Now I'll have another great source to send them to. Great job! This is invaluable!

Thank you for providing us with this content 🙏🏻

This has come at perfect timing! Thank you Dr. Huberman! You are saving my life! 👨‍🏫👨‍🔬 I have some sort of rare disease - 23 specialists - attacks of hypothalamic abnormalities. I have followed your tips closely and have been able to create a semblance circadian balance after a lifetime of tremendous daily struggle. Thank you for offering your wisdom to all of us. As you know, your information is top notch; I have shared your research with some of my physicians and they enjoy it too. Wishing you continued success in all of your endeavors. 🌟

Love your podcast. As a new mom and someone trying to get to a more optimal life style, I find this podcast to be an incredible source of trusted information I might not otherwise have access to. So thank you. I’m kind of a all things health enthusiast. TOPIC that I would LOVE for you to break down is toxicity and how we can avoid it, detox, or limit it. How it has impacted our body, and optimal health over time. I have listened to several resources, but most of which are personal stories and some science. I would love the pure science aspect of it, and how to combat it in such a toxic world.

I’m doing a super restrictive diet because i have sibo (small intestine bacterial overgrowth) , i’m also taking several natural supplements and after 3 months of doing it i’m feeling like another person. Not only my digestive symptoms got better, but also my state of mind got better. I’m less anxious, more positive, relaxed and got a better self-esteem. Thank you for this content. I think most people still don’t know about the importance of a healthy microbiome and i hope that changes soon!

Excellent podcast! You continue with fill my brain with what I consider to be some of the most relevant information available. One thing I would like to add is that some of the fermented food (and kombucha) sold in the refrigerated section of grocery stores are still pasteurized, therefore void of probiotic benefits. Be sure the label says something like raw, fresh, un-pasteurized, contains live cultures, ect. Try to support local venders, and try not to support pesticide use. The best option is to make it yourself though. It's easy!

Thank you for your amazing work, I teach high school health and physed, and I have been using your podcast episodes to create much of my health content.

Listened to this while on a staycation in Kansas City. So insightful and helpful as always. Thanks Dr.!

The timestamps are immensely appreciated, thank you Andrew!

Will you ever discuss psoriasis & similar autoimmune diseases? I'm curious if there is any new science on how to resolve this kind of health issues.. A lot of dermatologist or MD's usually say there is no cure, and that individuals just have to learn to live with this. They also prescribe topical corticosteroids and that's it. I have a GUT feeling there's more answers & solutions.. Please help 🙏

Dear Dr Huberman, I am a visual learner (at least in large part). I would find some slides - with bullet points and diagrams (they don’t need to be particularly beautiful, but I have a difficulty maintaining my concentration in complex topics without some basic visual aids. Also I recently saw a video which mentioned that there is also a microvirome (I think that the correct word) and they are also involved in a kind of symbiotic relationship with our biology- a relatively new area of research. I expect that will be in the next video.

Thank you Andrew! Thank you for sharing your knowledge. So helpful! Can't wait to share it with the people that can find it very very helpful!

Andrew, love the way you make important information accessible. Share your podcasts with many friends and family. My 21 year-old daughter turned me on to you.

Great episode, thanks:) Dear Mr.Huberman, I'm Anna, I'm from Ukraine even that I not there now, I trying to help in all possible for me ways. This last days were harsh and we don't know how many more days ahead are still be like that. I listen your podcast for some time already and it's really cool thanks for sharing. One thing that right now for Ukrainians (or it can be more generic) will be helpful is knowledge on how to stay healthy (to extend it's possible) when people are experience constant stress and anxiety. How make yourself falling asleep when it quite difficult? What should be cosider for nutrition when resources are limited? And so on. It would be great if you can share your knowledge on how to survive and live when it hard. Thank you in advance. Best regards, Anna

Gosh! As a kid on a small one cow dairy plus chickens, turkeys and all kinds of other livestock cats, dogs, raccoons, eating dirt, Either I’m destined to be a super soldier or like a walking Andromeda Strain.

Very informative video! I was engaged during the entire video. Thank you Andrew for bringing us such high quality information 🙏🏾❤️

This is the stuff that lights me up!!! Thank you so much for this fantastic summary of gut health (which is enjoyed while eating my homemade Natto and beet kraut😋) and I am EAGERLY anticipating next weeks episode with Dr. Sonnenburg! 🙏💜🤗

As a person who is undiagnosed, but suspects myself to have ASD-1 as well as ADHD, I am completely happily surprised to have been able to sit through this entire presentation completely undistracted. And now I feel like I have thorough understanding as to how to provide self-aid in a cost effective way to reduce my symptoms. This is golden information. Thanks again, Dr Huberman!

Can I please go to school again and have professor Andrew as a teacher?

Oh, the topic I was waiting for the most. Thank you Andrew!

Physicians got me WRECKED more than I already was. I would listen to you and myself more than the 3 gastroenterologists that don't read up on the latest research and studies but prescribe what they were taught to in MED school

Hello Dr. Huberman! I was wondering if you could Maybe cover an episode on migraine auras and why they happen? How the eyes end up going temporarily blind until the migraine goes away. Scary stuff. Don't quite understand why they happen. Thanks in advance! -Josh

I trust this guy more than any doctor Ive ever been to

Thank you for this information! I watched this because I’ve had terrible brain fog from talking strong probiotics. However, the probiotics have completely cleared my acne. So now I need to search “how to make fermented foods palatable for the picky eater” and hope it keeps my acne at bay.

I always listen to your podcasts in the morning at my shop; I have to confess that sometimes I listen to the same episode several times to truly understand and process all the information and every time a customer walks in and listens a little bit they ask me for the name of the program/show that I’m listening to; I tell them with a smile on my face: -“oh, it’s the Huberman Lab” After explaining how interesting your podcasts content is for physical and mental health, I show them on their phones where to find it, they subscribe to it and later call the shop to thank me for the recommendation 🥰
