Recently, I interviewed Julie Olson returns to talk through what’s really going on behind hair loss and the confusion around biotin. We get into why true biotin deficiency is rare, how high doses can interfere with other nutrients, and why it’s so important to step back and look at the bigger picture things like gut health, inflammation, toxin exposure, and hormone balance. If you would prefer to listen to the interview you can access it by Clicking Here.

Julie Olson:
Thanks, Eric. That’s a little bit of an older bio. I didn’t realize you had that one, but it’s all good.
Dr. Eric:
I did ask you. You said in the email when we scheduled this that I already had your bio. The good thing is it said more than 10 years’ experience. Whether you have 15 or 20, it still applies.
Also, this just happened. You have an abstract that’s been published in Integrative Medicine: A Clinician’s Journal on biotin supplementation, which we will be talking about.
Let’s jump into that topic. I don’t know if you’d say biotin is very controversial in thyroid health because most people probably don’t think it’s controversial. Most people think biotin is something we take when we’re losing hair. There are people who are aware that it can interfere with lab results, not just thyroid labs, which we’ll talk about.
Your research explains that it is controversial. Biotin, in the case of a deficiency, you might want to take possibly. So many people are just randomly taking biotin. Many of these people arguably don’t have a deficiency or don’t know if they have one because they haven’t tested for biotin. I’ll let you take over. How did it become one of the main supplements for hair loss?
Julie:
It earns its reputation from early case reports showing dramatic regrowth in cases with severe biotin deficiency. People with rare biotin deficiency is rare. It’s rare in developed countries. National Institute of Health says it’s very rare among individuals in general because you get biotin in your food every day. You get enough. The RDA is 30 mcg. They’re selling 10,000mcg.
Let me tell you who gets a biotin deficiency. It’s a very rare genetic disorder called biotinase deficiency. Long-term antibiotic use or long-term TP independence, which is IV feeding. Antiseizure meds cause that deficiency. Alcoholism or liver disease. IBD as well.
Dr. Eric:
Crohn’s or ulcerative colitis?
Julie:
Yes. You can see it’s few and far between when people have a deficiency. Taking too much causes a plethora of problems. Do you want me to go into that?
Dr. Eric:
Yeah, let’s talk about what too much is. How much is too much? What problems can taking too much cause?
Julie:
Anything over 4,000mcg. Keep in mind, it is a B vitamin. People think, “I can just pee it out. It’s not fat soluble.” Taking too much does cause a toxic reaction. There are safety measures. It gets the body out of balance with nutrient interactions and deficiency. It interferes with the absorption of B5, B6, B12, alpha lipoic acid, and ferritin, if it’s iron. It can cause metabolic disruption, kidney and liver strain. It can alter glucose metabolism. It can exasperate hyperglycemia in diabetics. It can mask important regulatory mechanisms that can potentially cause stress on the kidney and liver function.
Interesting that it’s marketed as a beauty vitamin. Early case studies. The beauty industry just ran with it, like they do with other things. Biotin does trigger skin problems in some people. High doses provoke acne, cystic acne even. I even had a client where that happened to herself and her cousin. Allergic reactions and rashes. It also disrupts the dysbiosis and skin microbiome at high doses.
For instance, Costco is selling 10,000mcg of biotin. No one would know that’s 300x the daily requirement.
It also interferes with over 200 lab tests, including labs for thyroid markers. Do you want me to run through some of those?
Dr. Eric:
Yeah, let’s talk about the tests. You can run through them first. I also want to know how much biotin does it take to interfere with the results? If someone is taking a biotin supplement or a multivitamin with biotin, should they stop taking it a few days or a week before? Let’s talk about that, too. Whatever order you want.
Julie:
Sure. You want to stop 5-7 days before taking any labs. Not only thyroid labs, but it interferes with these other lab markers. Vitamin D, 25 hydroxy Vitamin D, estradiol (the E2 test), folate, progesterone, testosterone, thyroxine, T3, B12, insulin, anti-HAV IgM, cancer antigen, creatine kinase. This is on my website on a blog.
Dr. Eric:
We can add a link to this.
Julie:
FSH, ferritin, HCG, agglutinizing hormone, NT-proBNP, prolactin, prostate specific antigen (PSA), thyroglobulin (TG), troponin, which is a marker for cardiovascular.
Dr. Eric:
Probably should have just asked you which markers does it not interfere with. That may have been a quicker list. It interferes with a lot of labs and markers. You said to stop 5-7 days prior. Is that at any dose? If someone is taking a B complex that has 400mcg of biotin, for example, should they stop taking biotin for 5-7 days?
Julie:
I think to be safe. From all the literature I’ve gone through, that would be the safest way to get the best test result.
Dr. Eric:
Regardless of if they are taking higher doses separately versus lower amounts in a B complex or multivitamin, you would say to play it safe, to get it out of your system. I didn’t realize it could cause liver and kidney strain.
Julie:
Yeah.
Dr. Eric:
I would imagine that’s at really high doses, right?
Julie:
Yeah. I was surprised when I got to researching this. I know we talked about it years before I even researched it. Once I dove in, it was just alarming. That’s why I wanted to talk to you and your audience about it. Don’t waste your money. It does more harm than good, taking so much biotin.
Dr. Eric:
What would you say to someone who is taking biotin, and they swear it’s helped with their hair? Does that mean they were one of the rare ones who had a deficiency? Could there be another reason?
Julie:
Good question. Probably some of the precursors got into better balance. They grew some hair. Some of the other nutrients for hair, like amino acids, zinc, iron, those cofactors properly. It helps grow their hair. That’s why they see the baby hairs.
Dr. Eric:
I’ll be honest. I don’t test for biotin. Some of the tests that we both do have biotin markers. I know you do an organic acids test, which has metabolites for biotin. If it’s elevated, typically one has a biotin deficiency. Do you do DUTCH testing?
Julie:
Yes. I do NutrEval, which tests biotin.
Dr. Eric:
Are those your go-tos? Do you ever test for biotin in the blood?
Julie:
No, not in the blood normally. I use the blood test version and the urine version of the NutrEval. It will look at it both ways. Doing other labs to see where their inflammation is, where their deficiencies are, where their toxins are.
I mentioned to you before, with your specialty, there is a lot of causes, but the five root cause categories I have put hair loss into are inflammatory, hormonal, gut, which includes nutrition, toxins, and stress. I make sure that we remove any of those, especially stress and toxins, before even going further and trying to repair their gut. First, getting out all the toxins and stressors. Sometimes, it’s not in their body; it’s in their environment. It takes a long time. Some people get frustrated.
Dr. Eric:
Definitely a work in progress with both stress and toxins. We are always dealing with stressors. We are always dealing with toxins and toxicants. You’re right.
You mentioned toxins. I always think about reducing toxic load, things like cosmetics and cleaning products. Some of these cosmetics, getting back to biotin. The shampoos, don’t they have biotin in them, too? Should someone look at their hair products and also-
Julie:
There’s not enough in shampoo.
Dr. Eric:
To affect the labs? I just wanted to make sure. If they are taking it in other ways, it’s mainly orally that is a concern. Good to know.
You mentioned some other testing in general, not just for biotin. When someone is dealing with hair loss, you take that root cause approach and look at all the different things you mentioned, starting with stress and toxins, but also inflammation, gut health, and hormones. Thyroid hormone imbalances can cause hair loss. Too much thyroid, too little thyroid hormone can cause it.
Are there certain tests you do from a functional medicine perspective in everybody? Do you do a comprehensive stool test on everyone, an organic acids test on everyone? Does it depend on the person, their health history? The NutrEval, you also mentioned. I’d like to know what tests you do on everyone, or at least most of the clients you work with.
Julie:
Good question. I do have my favorites, which you just mentioned. It depends on the individual and their budget.
Dr. Eric:
If someone can only afford one functional medicine test?
Julie:
It would be a tossup between the GI Map and NutrEval, depending on how they present.
Dr. Eric:
That’s what I wanted to hear. You have to dive into their health history and see. If they have a lot of gut issues, maybe the GI Map. They could show a lot on the NutrEval, too, because that looks at some dysbiosis markers and yeast. That’s why you have to look carefully at the health history and determine what testing.
Do you do any SIBO testing?
Julie:
If they present, yeah. I’ll do it if they think they need it.
Dr. Eric:
Do you also do, if necessary, mycotoxin testing? Cool. We do a lot of the same tests. I’m like you, too. If money wasn’t an issue, let’s do all of them. Obviously, finances is still an issue. Even if it isn’t an issue, it’s like you can’t afford everything. In that case, I want to make sure to do the priority tests. If someone absolutely insists on doing more testing I recommend, that’s up to them. Usually, it’s more the opposite, where someone might only be able to afford one or two, and you have to pick and choose.
Are there any common findings you see with your hair loss patients with some of these tests, like the GI Map for example? Any of these functional medicine tests.
Julie:
I see a lot of the Streptococcus elevated. That is a potential pathogen. It’s a bacteria that can-
Dr. Eric:
Opportunistic.
Julie:
Yes. I see that in almost everyone I test. I see a fair amount of H-pylori. Of course, inflammation in the gut. Low elastase. If I do the zonulin marker, that’s often elevated. Beta glucuronidase. A lot of dysbiosis. Low Akkermansia. Is that what you’re finding?
Dr. Eric:
Streptococcus, I agree. Most of my patients, when they do a GI Map, usually that shows up. Akkermansia is pretty commonly lower or less than detectable limits. The pancreatic elastase. Beta glucuronidase, it depends. Definitely more than 50% show low pancreatic elastase. Probably low Akkermansia. Definitely the elevated Streptococcus. I would probably say less than 50% of my patient base has elevated Beta glucuronidase. I wouldn’t say it’s like most of the people I work with. Secretory IgA is one that is commonly low. Sometimes high, but many times, low.
Julie:
Oh okay. More times low with you? Okay.
Dr. Eric:
Yeah. Probably 80% of the time, it’s on the lower side. Sometimes- You see a lot of elevated secretory IgA?
Julie:
Yeah. I see low, too. I equate that to they live in a paper thin house. They have no walls.
Dr. Eric:
Exactly. The mucosa, yeah. H-pylori, that’s definitely common. The GI Map is different than other tests. Most other tests just say you’re positive or negative. That uses a quantitative PCR, so it puts a numerical value on it. I find most people at least have it. It’s not always elevated. Most of the time, it’s detectable. Sometimes, not detectable at all.
Interesting test. I like the GI Effects from Genovva, too. I do the GI Map more frequently.
Those are the main factors when looking at hair loss. I was going to ask if there was anything else, any other nutrient deficiencies tie into what we’re talking about. Gut health. Toxic burden using up more nutrients.
Julie:
Parasites.
Dr. Eric:
Exactly. We are talking about Elizabeth Yarnell. Shoutout to her. She was on the podcast talking about parasites in the past. That’s one thing with the GI Map. I’m glad you brought that up. You and I like GI Map. If we ask Elizabeth, she would be like, “No, why test for parasites? They’re not completely accurate,” which I agree. They’re not perfect.
Julie:
I agree.
Dr. Eric:
Her argument is you can have parasites elsewhere: in the brain, other areas of the body, not just in the gut. For our purpose, we are focusing on the gut here.
I will say GI Map, I can’t say 90% of people I test for GI Map come out positive for parasites. When it’s negative, you can only go with the findings. If the person still has symptoms, maybe do further investigation. There are other companies like ParaWellness that focus more on parasites.
It’s interesting how different practitioners test. Some would not do the GI Map at all or any other stool test. We have a similar approach. They’re not perfect, the testing. Guessing is not perfect either. Just saying, “Let’s assume everyone has H-pylori or parasites or elevated Beta glucuronidase,” we want to try to get as much information as we can from the tests.
Everyone has a different approach. Different people have success taking different approaches. It’s not to criticize other approaches, but it’s nice to speak with someone who shares the same perspective when it comes to doing these tests.
Julie:
From my experience, for my first six years, I was a nutritionist for National Grocers, a national health food store with 250 stores nationwide. I couldn’t give labs. It’s so much easier for the client and the provider to say, “Look, you do have a gluten problem. Look, you do have parasites.” Instead of saying, “You have all the symptoms for it.” I get better compliance. “Look here. You do have dysbiosis. You do have H-pylori.”
Dr. Eric:
Yeah, that’s an excellent point. I test adrenals also. I like adrenal testing. We can make the argument that most people have adrenal issues. Stress is a big problem.
When I dealt with Graves’, and I have told this story a number of times on the podcast, but for those who haven’t heard this story, my adrenals were in the tank. Everything was low. Cortisol, DHEA, secretory IgA. I was very surprised, not because I didn’t think stress was an issue, but I thought I did a good job of managing stress. I convinced myself that I knew stress was a factor, but I was doing a good job of managing it.
Back then, I did an adrenal saliva test. If I didn’t do that test, maybe I wouldn’t have recovered, just because I needed to see how bad my adrenals were to really take action and block out time for stress management. I took some supplements to support adrenals. Then I retested. That was also equally important in my case because everything was low. A few months later, I retested and saw the improvements.
You’re right. It’s not to say you have to do every single test out there. If you don’t do any tests, then you could go by symptoms. Some people will get better that way maybe. If not, what direction are you going to go?
I think it’s fair to say try to do everything you can from a diet and lifestyle perspective. You could give up gluten even without doing testing to see if you’re sensitive to gluten. Even if you’re not sensitive to gluten, you should give up gluten because it has other effects, like on permeability of the gut.
I agree with you. Seeing usually leads to better compliance.
Julie:
In the long run, they’re going to also be able to retest and see the improvements. That can be helpful, too.
Dr. Eric:
Exactly. With hair growth, what are realistic expectations? Someone is losing a lot of hair. You find a number of different factors. Maybe there is some hormone imbalances going on, but there are also some gut issues. It’s multifactorial, like hair loss.
It’s different with men than women. Most of the people I work with are women. It could be distressing when they lose a lot of hair. What’s a realistic expectation as far as stopping hair loss and growing hair back? I know every case is different. You can’t say in every situation, it will be six months. But it takes time. It’s not three weeks, and their hair loss will stop and grow back.
Julie:
Yeah. I did have a client who grew her hair back in three months. You could really see it. Some other women, more have more. The diffusive thinning and maybe some bald spots where you can hide it and so forth.
The usual time is minimum of six months. Maybe a year or even more. Some women get really tied up because if you’re losing more than 100-150 hairs a day, day after day, month after month, as I was, and then it got so bad you could see my scalp as clear as day. This was when I was 38 years old. I’m 62 now.
A lot of women get stressed just with losing very little. They send me pictures. You can’t stress about that. That’s normal. My hairdresser said it’s normal to lose that amount every day, and it is. It is normal to lose hair. You do lose hair every single day.
When women have longer hair, it looks like more. You also lose hair with the seasons changing. I guess I’m answering your question the long way, but those are the time frames.
Dr. Eric:
It could take a year or longer to fully grow it back? The hope is that women will start seeing results well before then. Not that it would take a year to see the changes that are taking place, but to really get back to where they once were, where their hair once was.
I’m sure you have this question from people working with you. “I came across this product.” An example is Nutrafol or another hair loss supplement. Forget about the biotin. There are other things out there. I forget if Nutrafol has biotin. I know it has other things. Regardless, when someone brings up Nutrafol or another hair loss supplement, and they ask if they should give this a try to see if it will help assist in hair growth.
Julie:
Yeah, sure, if you want to try it. It’s not the magic bullet. If it was the magic bullet, everyone would take a hair supplement, and their hair would grow. I turn around every day, and someone else has a new hair supplement.
I won’t call out Nutrafol because I used to partner with them. They got bought out by Unilever. That’s why you see ads everywhere. They are produced and created in China. They have this proprietary blend. I was not comfortable with it. I’m sure it can do some good. It’s really expensive.
If you don’t get to the root cause of the hair loss, and you start piling on- That’s what women do. That’s what I did. You pile on supplements. You use products and do procedures. If your gut is a mess, or if you have toxins, you won’t absorb those supplements anyway. Maybe a little, so they will help a little bit. It’s like picking a scab and not letting it heal. If we just start layering on a bunch of supplements before you clear out the noise, the stressors, the toxins.
What I have come up with, and I want to ask you, are mercury fillings. I have a gal I just started working with, and she had a hair transplant. It only works for a couple years. Only 49% of hair transplants work long-term.
Anyway, she has mercury fillings. I prefer to get those removed before you start detoxing. Alpha lipoic acid, it will make it worse. Some of the detox nutrients make you sicker if you start detoxing someone with those mercury fillings. What’s your take on that?
Dr. Eric:
In a perfect world, I agree. If you have mercury amalgams, you would want to get those out asap by a biological dentist or someone who is taking proper precautions, not your general dentist, who probably won’t take proper precautions. I can’t say all my patients do that, or even most.
I say this. Mercury definitely can be a trigger for autoimmunity. It could even affect permeability of the gut, which I didn’t realize until a few years ago doing some research. I knew it was bad. So many things affect the gut microbiome. Didn’t know that was one that affects the intestinal barrier. We know mercury is not good.
I will say that a lot of people I work with have restored their health, even with the mercury amalgams. It’s not like it’s always preventing them from restoring their health.
But I only had one mercury amalgam, and I got it removed. I also had a root canal, which I got extracted and replaced it with a ceramic implant. Root canals are more controversial. We know for sure mercury is a toxin.
We could have another discussion on root canals. With mercury, I would agree. For an optimal health perspective, yes, you need to remove it. Even in some cases, there will be some people who don’t remove mercury amalgams. They are hitting that roadblock, where their antibodies aren’t normalizing, and they will remove mercury amalgams. That will be the missing piece of the puzzle.
I haven’t seen that with root canals. I have had patients remove root canals in an attempt to lower antibodies. So far, I haven’t seen that. It’s a small sample size. I can’t say I’ve had hundreds of patients remove their root canals. Mercury, I have seen have that effect.
I have also seen people normalize antibodies even when keeping mercury amalgams. It doesn’t mean they weren’t doing any harm. It just means it wasn’t creating an immune response, not to the extent where it was affecting those antibodies.
From a detox standpoint, you do want to be careful. If you’re detoxifying, the first thing you need to try to do is minimize your exposure to those environmental toxins. If you have mercury amalgams already, you are constantly being exposed to mercury. In a perfect world, you would want to remove them.
Not everybody is in a situation where they’re ready to do that, financially, because it is more expensive. If someone has eight mercury amalgams, and they will get them done by a biological dentist, it will cause thousands of dollars to get it done. They won’t want to do all eight at the same time. This is an extreme example.
If someone has two mercury amalgams, that’s more reasonable. We can make the argument that they should ideally remove the mercury amalgams before improving their health.
In the case of a Graves’ patient, they might get into remission without removing them. In your case, with someone with hair loss, they might be able to stop hair loss, grow it back, even if they keep their mercury amalgams. If they don’t, time wasted and money spent when they could have done it in the first place.
I do agree with you. Not everybody ends up removing them. I would like to think even those who don’t remove them and get good results will still consider removing them in the future.
Julie:
Agreed. Maybe they’re not having problems with the mercury now. According to the research, it’s just a matter of time. You might as well do it now.
Dr. Eric:
Agreed. In my situation, I only had one, which I thought I had more. That’s the thing. I had multiple fillings when I was younger. For whatever reason, and I did go to multiple dentists. Apparently, only one of them- I have been going to biological dentists for a number of years. This is my second or third biological dentist. Like I said, I thought I had multiple years ago. I was told I just had one. No complaints. I was glad I had just one.
Like I said, I had a root canal as well. That was more controversial. Wasn’t an easy decision honestly. I am not a big fan of root canals. The location. I just decided to get the root canal removed. Got the implant done.
Honestly, the implant, at least in my situation, I don’t want to say it was easy peasy. When I got the tooth extracted, I waited almost a year before getting that implant. I wasn’t fearful of the implant. I had extractions. I had a root canal done. I’ve had different dental procedures. I heard some nightmare situations with implants. After I got it, I wish I would have done it sooner. Sorry to go off.
Julie:
It’s interesting. I had eight.
Dr. Eric:
Mercury amalgams or root canals?
Julie:
Mercury amalgams.
Dr. Eric:
I assume you have none now.
Julie:
None now. I found a biological dentist here in Denver who used insurance. I got lucky.
I had some decavitations done by Dr. Nunnally in Marble Falls, TX. That’s all he does all day. Takes out mercury and decavitations. People come to him from all over the world. I refer my clients to him. They have a whole system that is not expensive. It’s three times less than some of the biological dentists here in Denver. That’s all they do.
Dr. Eric:
Sounds like a no-brainer. Since you’re saving money, get a ticket to TX if you don’t live there already. Maybe stay a night. I imagine for that mercury removal, you could probably go home same day if you really wanted to.
Julie:
No, you have to stay the night. You have a special hotel rate. They serve really clean gluten-free, dairy-free soup.
I have sent some women to him. It’s still a hard sell. Women don’t understand what their mercury has to do with their hair loss.
Dr. Eric:
How about gluten? How firm are you when it comes to people avoiding gluten? “You absolutely must avoid gluten if you work with me?”
Julie:
I test them on it. I can say you need to get off gluten until you’re blue in the face. When I worked as a nutritionist for Natural Grocers, I gave gluten-free testing fairs. Still some people would get off of it for a while.
Dr. Eric:
What do you test for?
Julie:
It didn’t matter. I do food sensitivity testing for it. When I can see it, and they can see it, they have a sensitivity. Some people are even Celiac and don’t know it because there’s silent Celiac. I test for it.
Dr. Eric:
You’re not just testing for gluten? You’re doing a food sensitivity panel that looks at gluten?
Julie:
Yeah.
Dr. Eric:
Maybe it’s rare, but what do you say if someone comes back negative for gluten?
Julie:
I still tell them that I’m the wrong person to talk to because I don’t think anybody should be eating gluten. I’m not as adamant about it if they test negative.
Dr. Eric:
This is where we differ. I can’t say I do food sensitivity testing on most people. The saliva test I recommend for adrenals. I recommend the Adrenal Stress Index from Diagnostics, and they look at gliadin. Gliadin is a gluten marker. Some people test positive. I can’t say that most people have an elevated gliadin. I don’t do the saliva test for gliadin. It just happens to be on there. If they test positive, obviously, I point that out and tell them to avoid gluten because they’re reacting.
Even if they’re negative, it’s not just about the sensitivity. It is also how it affects their gut. There is proof that it increases gut permeability, causes a leaky gut. If you do food sensitivity testing, and you test positive for gluten, that’s strong evidence that you want to avoid it long-term. Even if it’s negative, maybe you’re not reacting to it, but it doesn’t mean it’s not hurting you in other ways. Avoid it.
Julie:
They test for that, the anti-gliadin on the GI Map.
Dr. Eric:
True. I don’t know how accurate that is. Most people who do that test test negative.
What I was going to say, and this is important. A lot of people, when they work with me, they are already gluten-free. It will be negative if they have been avoiding gluten for a few months. It’s negative because they aren’t producing the antibodies for gluten.
If someone does a GI Map or food sensitivity testing- you do the IgG, right? You spoke about it before. Regardless, it doesn’t matter which test it is. If they have been gluten-free for three months or longer, we don’t know if they will react to gluten. Even if they have Celiac, if you avoid gluten for three months or longer, you won’t produce the antibodies.
I pretty much recommend everybody avoid gluten. Doesn’t mean that 100% will do that. Some people will do it 95%. You have to tell them even some small amounts of gluten, even once a week, it might be enough not to heal the gut.
It’s one thing if someone has a healthy gut already. Maybe they can withstand gluten every now and then. If someone is trying to heal their gut, and they are eating gluten once or twice a week, it might be enough to prevent their gut from healing.
Julie:
The fingernail amount of gluten creates the same damage, same result, reaction. I certified through Dr. Tom O’Brien’s Gluten Free Practitioner program.
Dr. Eric:
Yep.
Julie:
I have all these case studies. He said a fraction of a fingernail of gluten causes the same response. It’s all or nothing with gluten, whereas with other food sensitivities, not so much. Unfortunately.
Dr. Eric:
Agreed. This has been a great conversation. Before we wrap up, anything else you want to say? Any last words for those who have been struggling with hair loss for a while? Tried some things on their own. Maybe worked with a practitioner. What would be some next steps to take?
Julie:
Don’t fall for marketing myths. Test, don’t guess. Always look for the root cause instead of reaching for the next supplement. Your hair is speaking to you. Your hair is not the problem. Listen to it. Be grateful that it’s giving you some symptoms and clues that you need to dig deeper.
Dr. Eric:
Wonderful. Julie, where can people find out more about you?
Julie:
They can go to my website, FortitudeFunctionalNutrition.com. Search my name, JulieOlson.com, and it goes there, too. My social media handles are JulieOlsonFN, for Functional Nutritionist.
Dr. Eric:
Awesome. Thanks so much. This was really great. We spoke a lot about biotin initially and hair loss. We spoke about other things. Everything was tied into hair loss. Testing, mercury amalgams, all of this is important. If you have increased toxic burden, unhealthy gut, nutrient deficiencies, which can be related to the things we just mentioned, all this ties in together.
Julie:
If I could add. I have an updated quiz on my website. It looks for those five root cause categories. The quiz scores you. Is your highest burden hormonal? Is it inflammatory? Is it toxins? If the y go to my website, they can take that free quiz.
Dr. Eric:
Wonderful. Another reason to visit Julie’s website. Julie, this was great. Glad to have you back. I’m sure we’ll have you back again in the future.
Julie:
Thank you, Eric. It’s always great talking to you. I appreciate you being here. Thanks so much.
Dr. Eric:
Agreed. Take care.
Julie:
You, too.

Dr. Eric:
Great having Julie back on the podcast, talking a little bit more about biotin. She mentioned how you want to stop biotin before all blood tests. Not that it can affect every single blood marker, but she named a lot of different blood markers. Not just doing a thyroid test.
She said wait at least 5-7 days no matter what form and dosage, even if you are taking it as part of a B complex or multivitamin. If you’re taking a low dose, I don’t know if you have to wait a full week. Some sources say 3-5 days for a lower dose. Maybe to play it safe, five days.
Also spoke about biotin’s effects on the liver and kidney. High dose biotin might put stress on the liver and kidneys, which I didn’t know. Most of the B vitamins are safe. B6, you want to be careful about high doses. Biotin, I didn’t know.
We also had a conversation about removing mercury amalgams. I’m not sure if she recommends for everyone to remove them. I think it’s a good idea. Usually, I bring it up. I just learned over the years that most people aren’t, unless I say you absolutely have to remove them to get into remission. I haven’t found that to be the case.
From an optimal health perspective, you want to remove all your mercury amalgams. I only had one, and I thought I had more but was told by biological dentists I just had one. Got that removed. If I had more, I would have gotten the other ones removed.
I know some people are not in a financial position to do that. Like I said, if it was absolutely necessary for people with Graves’ and Hashimoto’s to get into remission, I would recommend it. In some cases, people might not choose to. Their thyroid antibodies aren’t normalizing, so we find that it is related to the mercury.
When detoxifying, which she also brought up, you want to be careful. You could still detox with amalgams, but there is controversy when using agents that potentially could chelate not just synthetic chelators like DMSA or DMPS or maybe alpha lipoic acid potentially. In a perfect world, you would want to remove amalgams before detoxing.
Of course, not everybody is in a position to remove those amalgams. If you have them, eventually you do remove them hopefully, but you want to make sure you go to a biological dentist or someone who takes proper precautions. To search for one, visit IAOMT.org, which is the International Academy of Oral and Medicine Toxicology.
Testing versus guessing. We both like to do functional medicine testing. I brought up Elizabeth Yarnell. We both know her. Both are in Colorado, so they know each other well. Elizabeth has been on the podcast a few times.
One thing I didn’t mention is Elizabeth does like MRT. It’s not like she likes no testing. She is a big proponent of MRT, which is a food sensitivity test.
When it comes to parasites, she doesn’t like to do stool testing because they are not 100% accurate. She is also not just trying to treat parasites in the gut but in other areas of the body.
Testing for gluten. She uses food sensitivity testing. She doesn’t use MRT. I remember her telling me in the past she uses an IgG test to determine if someone has other food sensitivities. She uses it for gluten, too.
Not a big fan of food sensitivity tests, which you know if you listen regularly. I usually recommend an elimination diet.
If someone is hitting a roadblock, it’s something I’ll consider. If someone insists on doing food sensitivity testing, sure. But it’s not something I recommend for most people.
After our conversation, I did ask her about hair dyes. I didn’t want to put her on the spot because I didn’t know if she dyed her hair, which I told her. I assume if she did, she would use something natural. I’m not a hair dye expert or hair coloring expert.
She said she uses a washout dye, which has very little peroxide. It sounds like she is using a little bit of hair dye, minimally.
I asked about henna because that is more of a natural alternative. She used it, and it dried out her hair. It sounds like there is no great alternatives for hair dyes, which I was trying to figure out. She said herself she uses a washout dye. She uses little peroxide. It sounds like it’s not a perfect solution. There probably isn’t a perfect solution out there.
Anyway, that’s all I wanted to cover here. Always great to catch up with Julie and talk about hair loss. If you’re experiencing hair loss, check out her website and resources.
Hope you found our conversation to be valuable. Appreciate you listening. Of course, look forward to catching you in the next episode.
