What is Thiamine

Thiamine is one of the B vitamins, known as B1. Its main responsibility is to change carbohydrates into energy and it also helps with the digestion of proteins and fats. Thiamine is necessary for proper release of hydrochloric acid in our stomachs, which is required for proper protein digestion. Most people with Hashimoto’s have low stomach acid or do not release any stomach acid.

The recommended daily allowance for thiamine is only 1.1mg for women >19 years of age, and may not meet the needs of those who are on a grain free diet and have malabsorption issues.

Food sources of Thiamine include fortified grains, legumes and peas, nuts and seeds.

Furthermore, B vitamins become depleted in stressful situations that often precede the development of autoimmunity and in times when we are pushing ourselves and our adrenals to work harder.

Even when we are eating a nutrient dense diet, due to the growing conditions of our foods, we may still be left with nutrient deficiencies.

While I love the theory that we should get all of our nutrients from foods, that’s not always possible, especially for people with Hashimoto’s who have multiple food sensitivities and digestive difficulties.

Certain medications, including Digoxin (used for heart conditions), diuretics, especially Furosemide (also known as Lasix), as well as taking the seizure medication phenytoin (Dilantin) can also deplete the body of thiamine.

Thiamine deficiency has been deemed as a rare deficiency in the developed world, but this is due to fortification of cereals and breads. But if you’re on a grain free diet, you are very likely going to be deficient in thiamine, as thiamine is added to cereals and breads.

Severe thiamine deficiency is known as Beriberi, and is associated with swelling, tingling, burning sensation in the hands and feet, confusion, trouble breathing, uncontrolled eye movements. Wernicke-Korsakoff syndrome is a brain disease caused by severe thiamine deficiency that can present as confusion, memory problems and nerve damage.

Symptoms of milder forms of thiamine deficiency include: fatigue, irritability, depression, abdominal discomfort and trouble digesting carbohydrates.

Long term thiamine deficiency in those who consume any carbohydrates (even fruit) can lead to a build-up of pyruvic acid, which is a byproduct of glucose metabolism, and can lead to mental fog, difficulty breathing and heart damage. Those on low carbohydrate diets, are at a smaller risk of the build-up of pyruvic acid and may not any symptoms, except for fatigue.

Unfortunately, standard lab tests for thiamine deficiency will not show if someone is mildly deficient, they will only show a severe deficiency of thiamin.

If you’ve been struggling with fatigue, low stomach acid, carbohydrate intolerance, low blood pressure and your adrenals, you may have thiamine deficiency.


Our B1 (Thiamine) is formulated as a fat-soluble form with high bio-availability that lasts longer in the body! Helps fuel your body by converting blood sugar into energy. It keeps your mucous membranes healthy and helps to support the nervous system in addition to its role in releasing energy from nutrients in food. It is also thought to help regulate appetite… in addition, those with chronic fatigue syndrome, and those who undergo a great deal of physical stress or emotional stress can be deficient in B1.

Could Thiamine be the missing link to your thyroid fatigue, stressed out adrenals and low stomach acid?

We may be on a seemingly great diet, be taking the right supplements and doing everything in our power to feel better, but feel like we are making no progress. But many times, we may be one small change away from seeing a huge difference.

Fatigue is a common symptom of an under-active thyroid, but it’s also a symptom of many other associated conditions, including adrenal fatigue, food sensitivities, and various nutrient deficiencies. Often people with Hashimoto’s will be started on thyroid hormones, but continue to feel tired. As people peel back the layers of autoimmunity, some of them will be able to reverse their condition just by getting on a clean diet like the WHOLE FOOD PLANT BASED diet.

Italian clinicians Dr. Antonio Costantini and nurse Maria Immacolata Pala, have hypothesized that the chronic fatigue that accompanies inflammatory and autoimmune diseases may be a result of a mild thiamine deficiency. They had already found that thiamine helped relieve the fatigue in people with Ulcerative Colitis (an autoimmune condition that affects the gut) and decided to try using thiamine in three women with Hashimoto’s, who were on thyroid medications but continued to experience fatigue.

Two of the women were given an oral dose of thiamine (600mg) per day, while the third was given an injection of 100mg every four days.

All of the women were given a survey to rate their fatigue before starting the thiamine, and again the same questionnaire 20 days into the treatment. All three reported that they experienced a relief in their fatigue during the second survey, and two had a complete remission of their fatigue!

The woman who had the injection felt that her fatigue was lifted within 6 hours of receiving it, while the women who took the oral dose of thiamine felt relief within 3-5 days.

Interestingly, none of the women had thiamine deficiency on standard lab tests that are used to measure thiamine status.
