Fatigue, sleep disorders, depression, anxiety, fibromyalgia and cardiac troubles are some of the symptoms we see as the expression of a classic mild thiamine deficiency. Thiamine deficiency is very under-rated and under-recognized, and can have far reaching ramifications. And a magnesium deficiency and high dose magnesium can actually cause a thiamine deficiency. There are also many other causes of thiamine deficiency that may not be on your radar: a high carb/processed food/sugar diet, coffee, tea, alcohol, genetics, environmental toxins, medications, celiac disease, leaky gut, bariatric surgery and malabsorption.
It’s for this reason that I invited Chandler Marrs, PhD to speak on the Anxiety Summit 5: Gut-Brain Axis. We had so much to cover and it ended up being so long, that we split it into part 1 and part 2.
This is what we cover in Thiamine Deficiency in Anxiety and Gut Health (Part 1)
- Excessive carbs, alcohol, medications and genetics as causes of low B1/thiamine
- Dysbiosis, dysmotility, constipation, anxiety, depression, panic attacks, low energy
- Psychiatric and digestive effects: research, history and other symptoms
This is what we cover in Thiamine Deficiency in Anxiety and Gut Health (Part 2)
- The mitochondria, dysautonomia and POTS
- Other symptoms: hyperemesis, exercise intolerance, muscle pain, neuropathy
- Thiamine supplementation – forms, dosing and paradoxical reactions
Thiamine deficiency is under-rated and under-recognized
We start with why it’s an under-rated and under-recognized deficiency and Dr. Marrs shares that the assumption is that deficiency is not common and even when you test it looks like you are not deficient:
- “The assumption is that there is no such thing [as a thiamine deficiency] and that it’s rare unless you are a chronic alcoholic. And even then, it’s missed 80% of the time. Or you have a severe injury or illness that depletes thiamine rapidly.
- The presumption is that we’ve solved it, and it’s rare, and it only happens in countries where food availability is problematic.
- The reality is that the chemistry of our foods, the chemistry of our environment, the medications that we take all combine and accrue to not only deplete the available thiamine on the basis of intake but to increase the need and to damage a lot of the enzymes involved in the processing of thiamine.
- So a lot of folks are functionally deficient in that even though by definition they meet the daily requirement and they may, based upon lab testing, show up as being sufficient and not frankly deficient.
- And so, I think that we just have taken our eye off of the ball with regard to this particular nutrient.”
Magnesium deficiency (and high dose magnesium) can actually cause a thiamine deficiency
Dr. Marrs also shares how a magnesium deficiency (which is very common) can actually cause a thiamine deficiency:
- “One of the things that’s interesting is it requires magnesium to activate thiamine into its active form.
- If someone is thiamine sufficient and magnesium deficient, then they are actually functionally deficient in thiamine because you cannot take the free thiamine and activate it into thiamine pyrophosphate.
- So magnesium deficiency itself can cause thiamine deficiency. And there’s a good percentage of the population that doesn’t get enough magnesium.”
And she also shares how when taking high dose magnesium it’s so crucial to also be addressing low thiamine in order to prevent them becoming more thiamine deficient:
- “Now, the flip side of that is really interesting. And I think this is important for your audience, in particular, is that magnesium supplementation, when someone has a problem with thiamine, will actually shut down thiamine processing and mitochondrial processing at one of the enzymes. Because if you don’t have thiamine with magnesium, then the enzyme α-ketoglutarate dehydrogenase kind of shuts the whole sequence down.
- So if you are giving someone high dose magnesium, which is common to supplement, and not tackling the thiamine as well, you risk them becoming more thiamine deficient and reducing ATP output, energy output even further. So everything has to be in balance to some extent or another.”
I can think of one situation where this could be common. You use high dose magnesium due to constipation. Low thiamine may be one of the underlying causes of your constipation and now high dose magnesium is going to make the low thiamine situation worse.
Up to 30% of psychiatric patients have a thiamine deficiency
We talk about how up to 30% of psychiatric patients have a thiamine deficiency but that there hasn’t been enough work on psychiatric disorders which Dr. Marrs says “is strange given the fact that some of the strongest symptoms involve brain function and the most dangerous or some of the more dangerous damage is relative to areas of the brain.”
I share some quotes from a 2019 paper that does actually look at the psychiatric aspects – Neurological, Psychiatric, and Biochemical Aspects of Thiamine Deficiency in Children and Adults:
- “The brain is highly vulnerable to thiamine deficiency due to its heavy reliance on mitochondrial ATP production. This is more evident during rapid growth, i.e., perinatal and children.
- Thiamine deficiency contributes to a number of conditions spanning from mild neurological and psychiatric symptoms, confusion, reduced memory, sleep disturbances, and severe encephalopathy, ataxia, congestive heart failure, muscle atrophy, and even death.”
This paper also looks at the beneficial effect of thiamine supplementation in autism spectrum disorder (ASD) and other neurological conditions.
Below, I share some additional studies that we didn’t talk about in the interview but add value to the topic.
Fatigue, sleep disorders, depression, anxiety, fibromyalgia and cardiac troubles as the expression of a classic mild thiamine deficiency
This paper, High-dose thiamine improves the symptoms of fibromyalgia, states that “It is our opinion that fatigue, sleep disorders, depression, anxiety and cardiac troubles are the expressions of a classic mild thiamine deficiency.”
The authors share 3 cases where thiamine/vitamin B1 improved symptoms in all areas for all these women:
- Patient 1: Female, 58 years old, weight 59 kg. From 1998, the patient began to have widespread pain accompanied by severe fatigue, depression, anxiety, irritability, sleep disorders, trouble concentrating, dry skin, general sickness, continuous headache, intolerance to low temperatures and, more recently, episodes of tachycardia and extrasystolia [alteration in heart rhythm].
- Patient 2: Female, 37 years old, weight 74 kg. From 1999, the patient has had widespread pain and all the symptoms described for patient 1, with the only exception being that of cardiac symptoms.
- Patient 3: Female, 60 years old, weight 65 kg. From 2006, the patient began to have widespread pain, fatigue, depression, anxiety, sleep disorders. Trouble concentrating.
As you can see the symptoms can be very varied and this is what makes it challenging to identify low thiamine as being the issue.
Thiamine deficiency after bariatric surgery
Here one case study where thiamine deficiency occurred after bariatric surgery: Wernicke’s encephalopathy mimicking multiple sclerosis in a young female patient post-bariatric gastric sleeve surgery:
We describe a case of Wernicke’s encephalopathy secondary to thiamine (B1) deficiency in a patient status post-bariatric sleeve gastrectomy.
The presenting symptoms of new-onset weakness, diplopia [double-vision], and confusion in a young female patient raised suspicion for multiple sclerosis (MS), but given a history of bariatric surgery, thiamine levels were checked, revealing significant Vitamin B1 (thiamine) deficiency.
This case highlights the importance of thorough history taking, as a misdiagnosis of MS in this case could have resulted in irreversible neurological deterioration and hematological and infectious consequences associated with the inappropriate administration of disease-modifying therapies.
Bariatric surgery is one of many causes of thiamine deficiency.
Some of the other many causes of thiamine deficiency
Other causes of thiamine deficiency include factors that may not be on your radar: a high carb/processed food/sugar diet (and even consistent smaller amounts of “healthy” sweeteners), coffee and tea consumption, alcohol consumption (excessive consumption and even moderate consumption i.e. social drinking), genetics (we talk about specific genes in the interview), environmental toxins, certain medications, celiac disease, leaky gut and malabsorption etc.
We do a deep dive into all this in the two interviews (and much more).
Interviews that dove-tail well with this topic are these ones:
- Michael Collins – Sugar/Fructose Addiction: Anxiety, ADHD and Aggression (because sugar and carbs lead to low thiamine)
- My interviews, Glutamine, DPA and Tyrosine for Anxiety and Sugar Cravings and GABA & Tryptophan: Gut-Anxiety Connections (because the amino acids help you quit sugar/carbs, coffee and alcohol easily)
- Tara Hunkin, NTP, CGP, RWP – Mitochondrial Dysfunction in Anxiety (because low thiamine adversely affects the mitochondria)
I encourage you to register and tune in if you have:
- Anxiety & feel overwhelmed & stressed by little things
- Panic attacks &/or obsessive thoughts or behaviors
- Social anxiety/pyroluria
- Phobias or fears (flying, spiders or even driving on a highway)
And also if you suffer from…
- Food sensitivities, IBS/SIBO, parasites or gallbladder issues
- Constipation, diarrhea, bloating, gas, pain & other digestive issues
- Leaky gut, a leaky blood-brain barrier or vagus nerve issues
Join us if you are also an emotional eater with intense sugar cravings (and know you suffer from low blood sugar), experience insomnia, low mood, PMS, poor focus and/or low motivation.
This is THE online event to learn about the powerful individual amino acids – GABA, theanine, tryptophan, 5-HTP, glutamine, DPA and tyrosine – to quickly ease anxiety and help with gut symptoms while you are dealing with other root causes which take longer to address. (They also help with cravings as with this example, and sleep and immunity).
