Episode 28: Methylene Blue: Miracle Molecule or Just Another Wellness Trend?

Methylene blue has gone from a medical treatment to one of the most talked-about compounds in the wellness and biohacking world. Some people swear it boosts energy, sharpens focus, supports mitochondria, and even promotes healthy aging—but what does the science actually say?

In this episode, we're breaking down what methylene blue is, how it works in the body, and why it's generating so much attention. We'll explore its effects on mitochondrial function, brain health, oxidative stress, and cognitive performance, while also discussing the potential risks, medication interactions, and why more isn't always better.

Most importantly, we'll talk about the bigger picture: why no supplement can replace the foundations of health. Sleep, strength training, nutrition, stress management, and metabolic health still matter far more than any wellness "hack."

If you've been curious about methylene blue—or wondering whether it's worth adding to your routine—this episode will help you separate the science from the hype and make informed decisions about your health.

In this episode:
• What methylene blue actually is and where it came from
• How it may support mitochondrial function and energy production
• Research on cognitive health and neuroprotection
• Important safety concerns and medication interactions
• Why lifestyle foundations matter more than any supplement
• The role of blood work and genetics in personalizing your health journey

Because taking care of the body God gave you starts with understanding how it works.

Hey guys. So today we're going to be talking about a little blue liquid that somehow made its way from medical textbooks into biohacker TikTok. Methylene blue. If you've spent more than five minutes in the wellness world lately, then you probably have heard claims like it boosts your brain, it fixes your mitochondria, it increases energy, it helps with aging. It's basically magic. So listen, some of the science is really fascinating on it. But as always, the internet has a way of taking an interesting compound and turning it into something more. So today we are gonna break it down what methylene blue actually is, what it does in the body, where the science is promising, and where people are getting a little carried away with it. So here we go. Hey friends, and welcome to the Fit Nerd Podcast. This is the podcast where faith, fitness, and science all collide. I'm Abby and I'm here to help you work with the body that God gave you so that you can feel stronger, you can feel healthier, and you can feel happier in your everyday life. Around here, we geek out on all the good stuff. I'm talking genetics, nutrition, training, hormones, biohacking, even the spiritual side of health. Because you are fearfully and wonderfully made, understanding how your body works is one of the best ways that we can honor that design. For me, this isn't just about looking good today. It's about feeling good as I age. I want to be fit when I'm old and I want to enjoy life to the absolute fullest, which means feeling my best. And I want that for you too. So whether you're lifting, running, meal prepping, momming, or just listening on your drive, let's dig into the current fads in fitness, the truth in science, and the hope that we can find in faith so you can make the best choices for the amazing body that God gave you. This is the Fit Nerd Podcast. Let's get started. So, methylene blue is one of those supplements that my mom just randomly started taking because she heard that it was really good for you. And I was a little nervous about it. She gave me some, put it into my water, made my water like this beautiful bright blue color. But I was like, what is this actually doing to me, mom? What is this? And she was like, I don't really know. Um, I just know that it's supposed to be really good for you. So I was like, okay, well, let's look this up, let's figure this out, let's uh figure out what's going on here. So um, first of all, I first off, I was very surprised to hear that methylene blue is been around for a very long time, you know, late 1800s, and it was originally used as a dye, literally a dye, and then medicine realized that it actually had some effects on the inside of the body. And it's still used medically today in certain situations. But um, one of the biggest approved uses is treating a tissue a condition called methymoglobinemia. I don't know if that's how you say it, but um, this is where the blood has trouble carrying oxygen properly. So it's not like a brand new influence influencer supplement or anything like that. It's been around for a long time and doctors know what it does and they use it for people who need it. So um, this is a real pharmaceutical compound and it has real biological effects. But is it for everybody? Does everybody need this? And um, if you take it and you don't need it, is there gonna be any side effects? I wanted to know. So um let's get into why like the wellness world started getting pretty obsessed with it. And that's because it deals with, once again, always like the kicker for every one of these things we talk about, mitochondrial health. So you guys know that I talk a lot about my mitochondria all the time, and it's because they matter. I have low mitochondrial function genetically, so I'm always interested in anything that says that it will boost and help my mitochondria out. Um, there are little energy factories of your cells, and they basically do everything for our bodies, like energy, metabolism, brain function, hormone production, muscle recovery, aging, all those things, all tied back to your mitochondrial health. So methylene blue appears to help the electron transport chain work more efficiently. What that means is it is gonna help your cells produce energy better. Here's the cool part methylene blue can act as an electron donor and carrier inside the mitochondria. So in certain situations, it may help to bypass dysfunctional parts of cellular energy production. And that's why people report having better mental clarity, more energy, improved focus, less brain fog. And honestly, some of the research around neuroprotection is really interesting. Um, there are studies that look at its role in cognitive decline, neurodegeneration, mitochondrial dysfunction, and oxidative stress. I will tell you, these are all things that I absolutely worry about. Um, and probably most of us worry about, you know, I don't want to lose my mind when I get older. I have, you know, had two people in my family die with Alzheimer's, and that is not something I want. I, it's hard. It's very difficult. If you have anybody in your family that has has those issues, I want to combat that as much as I possibly can. So I am going to take supplements that will help my cognitive function. Um and I'm gonna stay away from things that will affect it. You know, that's that's just kind of how I roll. But this sounds like it's doing even more, like it's affect it's helping your cognitive function and neurodegeneration by also increasing your mitochondrial function, which I need, and helping with oxidative stress, which I also need. So um, that does not mean it's gonna be curing diseases, you know. Um, it just means that people are feeling the effects from it. So that's a big deal. But because the wellness world loves to hear it supports mitochondria, that means usually people are suddenly out there drinking all of this mystery blue chemicals that they bought online for companies. Who even knows if it's if it's real and and good quality, right? So make sure that you understand all methylene blue is not created equally. So some forms are industrial grade, absolutely not meant for human consumption. You have to be very careful because purity matters. We need to know you're getting it from a good source. Your dose matters. You can't just be willy-nilly squirting some into your water like my mom did. But um, but also those interactions matter. That's a huge one. That's one that you really do have to pay attention to because it does affect your neurotransmitters, specifically your serotonin pathways, which you know I've talked about this with depression, serotonin that's a whole nother thing. But it can affect very dangerously with the medic with medications that people are on that directly target serotonin. So SSRIs, SNRIs, antidepressants, psychiatric medications, and even certain stimulants. These are all gonna affect your serotonin. So if you're on anything like that, you need to be very careful because in rare situations, that combination can contribute to something called serotonin syndrome. And this could be very serious, very fast. Methylene blue is not just a harmless wellness supplement, it can be a biologically active compound if it interferes with your serotonin. So let's talk about performance and energy. A lot of people say that they feel mentally sharper, more motivated, more physically energized. And part of that may genuinely be mitochondrial support, but part of that may also be its effects on brain chemistry and cellular signaling. So that means that if your sleep is trash and your nutrition is trash and your stress is through the roof and your blood sugar is like a roller coaster, then methylene blue is not going to magically transform your health. You cannot supplement your way out of a dysfunctional lifestyle. And I know people hate hearing that, but it's the truth. So um before you jump off and do something like this, you need to make sure that you are taking care of yourself and this would be something that you would add on top if you truly need it. Personally, I think methylene blue is one of those compounds that's genuinely intriguing. And but I do think you have to respect it. Not like fear it, but also not worship it, um, but respect it for sure. So because some people in the wellness world are acting like this stuff is like the fountain of youth in a drop or bottle, but historically, anytime that we start believing that, we often see some some downsides. So um basically the foundation matters your sleep, your strength training, your movement, your protein, your sunlight, stress management, nervous system regulation, metabolic health. Those all need to be very much so taken care of. And that is the stuff that changes your life long term. Supplements are great. I love supplements. I think supplements are awesome supports, but they're not the main character. And honestly, that's my biggest issue with a lot of the modern wellness culture. But um people typically want shortcuts and they want quick fixes. This one is considered a hack, and I think it can be really great. I really do. But make sure that you are not running off of five hours of sleep or scrolling on your phone till midnight, not eating enough protein, eating junk, not lifting any weights, stressed out all the time, and then expecting to take drink some blue stuff and that it's just gonna make you feel better. It probably will make you feel better. It will, but you need to do the other stuff too. So, um, in order to feel better. So your mitochondria are not confused in this situation, your lifestyle is. So if you're just boosting your mitochondria but you're still living a rough lifestyle, then um the methylene blue is gonna help your mitochondria, but think of how much better you'd feel if you're getting on top of everything else. So um methylene blue. Is it interesting? Absolutely. Promising, potentially magical, no. If you're considering it, especially if you're on medications or you have any underlying conditions, this is one of those things that's worth discussing with a medical professional, not just a podcast person or a TikToker or something. I I would absolutely recommend doing some some heavier research in this. I also always believe in before you're adding a supplement like this, make sure you've done some testing on your body. I fully believe in blood work. I I will tell you once again, I think annual blood work is good for everybody. And I found something interesting lately. Quite a few people actually, I didn't know this was a thing, um, that I've talked to have been, they don't, they told me they don't do blood work because they are fearful about what the outcome is gonna be. And I find that really interesting because my brain doesn't really work that way. Actually, my brain thinks, let's do some blood work and let's make sure everything's functioning well so that I know how to make it better. I haven't been scared of the results. Um, and I'm also, I mean, I've believe that we need to do our due diligence for our families, you know. I don't want there to be a surprise for my husband or for my kids. I want us all to be prepared if I'm dealing with something and also whatever is not in balance in my body, let's balance it out. Let's figure it out. If I, if I'm low in something like vitamin D that can affect all my hormones and affect a ton of different processes in my body, but it's a quick fix to just be more on top of my vitamin D. Why wouldn't I want to do that? You know? Um, I mean, that's just my opinion. But I think all of you guys need to go get some blood work done and just see where you're at. If you're scared of needles, do it and just find out what's going on there. There's so many options. You don't even have to go through a doctor. You can use a lab, you know, lab core quest. You can request kits from them. You can do the any lab test now or the walk-in labs and just get a full panel done. And I think it's really important. I also think it's important for our kids as they get older to see where they're at. And I feel like we could help them by making sure that their bodies are functioning their best. It makes them better humans, better athletes, better workers, better students, all of those things if their levels are correct in their body. And it could be something like they aren't eating enough vegetables and that's showing up on blood. It could be something more serious that um you need to address and you need to take care of, you know. Um, I just believe we have this need and this responsibility to take care of our bodies that God gave us and take care of our children's bodies and um push your spouses to do it and just make sure everybody's healthy and in good shape. I do think that lab work is the best way to do that. Um, I also, of course, think knowing your genetics on top of that is gonna be huge. You know, the combination is gonna be so beneficial long term to know what your bodies naturally can do and naturally can't do, then that can be a direct reflection of blood work and some answers to maybe why blood work looks the way that it does, because of genetically who you are. So, anyways, that's my little soapbox moment. Um, I want you guys to take care of your bodies, take care of yourselves. That way you don't just jump off and go buy something like methylene blue if you don't need it, you know, and you might have a whole storage cabinet filled with all your vitamins and your supplements and everything, but you might not need them. You know, you need, I think it's important to know what's going on internally and not just throw things on top of it without taking care of the foundation. And um, and you might need some extra help, you know. I mean, honestly, reading about methylene blue, I probably need this stuff. I do. Like I really probably do. I think um I have all of the issues that it's designed to help. I don't always take very many supplements. I only take the things that I truly need. But like my daughter needs different supplements than I do. Um, but I wouldn't know that if I didn't do our blood work and also our genetics. So, um, anyways, that's my that's my little lecture for you guys today. Go take care of yourselves, go get some blood work done, go get your genetics done, find out how your body's ticking, what's going on, if there's anything that needs to be addressed, and then supplement where you need to.
