Vitamin B1 Benefits: What You Need To Know

Vitamin B1, thiamin, or thiamine, is a vitamin that doesn’t get as much attention as some of the other members of the B vitamin family. But did you know that Vitamin B1 is an essential component of the B vitamin complex and plays an integral role in the human body? Yes, Vitamin B1 Benefits are numerous and it is an essential nutrient that your body would be lost without. 

What Are The Vitamin B1 Benefits and How Can It Help Me?

vitamin b1 benefits Vitamin B1, also known as thiamin, was the first B vitamin that scientists discovered. This is why its name carries the number 1.1 It is an essential micronutrient that regulates various processes throughout your body which includes the following benefits:

Neurological benefits

Studies show that getting enough thiamine in your diet is necessary for maintaining healthy brain function and preventing age-related neurodegeneration. Thiamin also plays a role in the synthesis and regulation of neurotransmitters, the chemical agents that help nerve cells communicate. It appears to be beneficial for older people with Alzheimer’s disease and every type of dementia.2

Acts as an anti-stress nutrient

Vitamin B1 also works as an anti-stress nutrient which helps your body deal with any condition that causes stress. Your immune system, for instance, is compromised by stress, and your mood and overall physiological well-being also suffer when you’re stressed out. A four-month study found that getting plenty of vitamin B1 in your diet improved mood in subjects and reduces stress levels. One study found a link between baseline thiamine status and mood in young healthy females. After taking a multivitamin supplement that included thiamine, mood improved when thiamine status improved, and the mood was poorer when thiamine status declined.3

Cardiovascular benefits

Thiamine acts as a cofactor for the neurotransmitter acetylcholine, which is integral to maintain steady and healthy cardiac functioning. This essential nutrient also appears to lower your blood pressure, which lowers your risk of developing chronic hypertension. If you’re deficient with thiamine, the heartbeat becomes irregular and can cause other cardiovascular conditions.4

Acts as coenzymes in energy metabolism

Vitamin B1 is an essential part of energy metabolism. Our bodies get their energy from foods containing fat, carbohydrates, and protein, but they need help to use that fuel. And that’s where vitamin B1 comes in! It helps break down glucose, an end product of carbohydrate metabolism, which your body uses to transmit energy to all your organs and tissues. The body needs thiamine to make adenosine triphosphate (ATP). This is a molecule that transports energy within cells and is used in connection with weight loss.5

Additional Vitamin B1 Benefits

In addition to above, Vitamin B1 benefits still offer various options. Scientists have looked at thiamine as a possible treatment for:

  • Cataracts
  • Kidney disease
  • Imbalanced electrolytes flow into and out of muscle and nerve cells
  • Beriberi
  • Ulcerative colitis
  • Persistent diarrhea

Vitamin B1 (Thiamine) Deficiency

A deficiency of vitamin B1 commonly leads to two major health problems: Beriberi and Wernicke-Korsakoff syndrome. Beriberi, is a condition that features problems with breathing, eye movements, heart function, and alertness. It’s caused by a buildup of pyruvic acid in the bloodstream, which is a side effect of your body not being able to turn food into fuel.6

Wernicke-Korsakoff syndrome is technically two different disorders. Wernicke’s disease affects the nervous system and causes visual impairments, a lack of muscle coordination, and mental decline. If Wernicke’s disease is left untreated, it can lead to Korsakoff syndrome which permanently impairs memory functions in the brain.7

Early Vitamin B1 (Thiamine) Deficiency Leads to Symptoms such as:

  • Loss of appetite
  • Irritability
  • Reduced pain tolerance
  • Fatigue
  • Constipation
  • Mental depression
  • Nausea
  • Peripheral Neuropathy 
  • Muscle cramps

How to keep your Thiamine levels up

B1 (Thiamine) and all other B vitamins are water-soluble and do not stay in the body for long. The body cannot store them, and they are soon excreted in the urine. Because of this, water-soluble vitamins need to be replaced more regularly.8 The National Institutes of Health (NIH) has established the recommended daily amount (RDA) for thiamin at 1.2mg for adult men and 1.1mg for adult women. This RDA increases to 1.4m for women who are pregnant or lactating. Although it can be obtained from the diet, that usually isn’t sufficient. Heating, cooking, processing foods, and boiling them in water can destroy thiamine.9
