What is Thiamine Mononitrate?
Thiamine mononitrate is a nitrate salt form of Vitamin B1. The food and drug industries use thiamine
mononitrate in supplements and foods as it is a stable form that can counteract the loss of vitamin B1
during processing. Like all B vitamins, thiamine mononitrate is water-soluble and an essential nutrient.
Scientists named it vitamin B1 in 1910, as it was the first identified water-soluble vitamin. It is a
prerequisite for every cell in the body to produce adenosine triphosphate (ATP), the body’s primary fuel
source for energy. It’s also crucial for proper nerve function and metabolizing carbohydrates, fatty acids,
glucose, and branched-chain amino acids (BCAAs).
Potential Thiamine Benefits
Thiamine mononitrate is a critical factor for producing cellular energy. It is a cofactor for pyruvate
dehydrogenase and 2-oxoglutarate dehydrogenase. The body uses these enzymes to synthesize ATP for cells to
use as energy. The body can also store ATP as energy for future use.
Vitamin B1 plays several important digestive and metabolic roles. It is an essential cofactor for enzymes
that metabolize carbs, lipids, BCAAs, and glucose. Thiamine plays a role in breaking down proteins too. It
also stimulates hydrochloric acid production for better digestion.
Vitamin B1 is important for a robust immune system. Stressful conditions and circumstances can weaken the
immune system, but thiamine boosts immunity by strengthening its resistance and endurance during these
situations. Unsurprisingly, thiamine deficiencies decrease the effectiveness of immune system functions.
Thiamine is an essential component of maintaining a healthy central nervous system. It supports numerous
cognitive functions, and it’s critical to form the myelin sheaths that protect nerves. Without sufficient
thiamine, individuals may begin to experience neurological symptoms.
Thiamine Deficiency Symptoms
The richest food sources of thiamine include yeast, whole grains, pork, legumes, and some fruits. Certain
risk factors put individuals at a higher risk of developing a thiamine deficiency. These include:
- Eating a white rice-based diet
- Regularly consuming raw fish or shellfish
- Drinking a lot of coffee or tea
- Taking large doses of diuretics
- Long-term diarrhea
- Alcohol misuse
- Genetic conditions that inhibit thiamine absorption
- Gastrointestinal diseases that affect nutrient absorption (i.e., celiac disease)
- Weight loss surgery
- Thiamine malabsorption due to natural aging processes
Thiamine deficiencies can remain undiagnosed for a long time, as the symptoms are often vague or mimic other
health conditions. Some common signs of a deficiency include:
Fatigue. A thiamine deficiency can cause fatigue within a few weeks, as the body needs
vitamin B1 to produce energy.
Loss of appetite. An abrupt loss of appetite is one of the first markers of a thiamine
deficiency. Thiamine helps the brain transmit hunger and satiety cues. A thiamine deficiency disrupts
this process, and the brain may signal that the individual is full even if this is not the case.
Consuming fewer nutrients through food can cause other deficiencies as well.
Losing weight without trying. Eating less often translates into unintentional weight
loss. Losing too much weight too quickly can wreak havoc on the metabolism. It can also cause several
health problems if the individual becomes underweight.
Neurological symptoms. Individuals with a thiamine deficiency can experience an array
of neurological problems. They may suffer from brain fog, have difficulty concentrating, or struggle to
think clearly. Severe deficiencies can cause memory loss and hallucinations. Neuropathy is also common,
and it is the most well-known thiamine deficiency symptom. Individuals with neuropathy may experience
pins and needles in their hands and feet, tingling extremities, loss of sensation in their hands, and
loss of coordination.
Potential Thiamine Side Effects
Most individuals tolerate thiamine mononitrate well. As a water-soluble vitamin, the body excretes any excess
thiamine it doesn’t need. However, consuming excessive thiamine doses can have serious side effects.
Individuals with a sensitivity to vitamin B1 may experience hives, itching, flushing, or nausea after taking
supplements. Consult with a physician before taking any new supplements.
