Best Thiamine Supplement: The Number One B Vitamin Everyone Needs!

Are you tired of frequent headaches and constant fatigue? Do you find yourself irritated, or worse, going through seizures? If so, then there is a high probability that your body is deficient in thiamine.

Thiamine, the leading member of the Vitamin B family and also called Vitamin B-1, is an essential nutrient required by our bodies. It is important for all tissues and cells to survive. Because of this, a daily intake of vitamin B-1 is crucial to have the healthiest life.

In this post, we’ve brought together everything you should know about thiamine. We have also reviewed what we believe to be the best thiamine supplements.

What Is Thiamine?

Back in 1910, the Japanese researcher Umetaro Suzuki discovered the first B Vitamin. It became known as thiamine or thiamin. Soon, it acquired the name of Vitamin B-1 as more members entered the Vitamin B family.

Vitamin B-1 is a water-soluble vitamin. Its core purpose is to convert food into energy to improve the function of the:

  • Nervous system
  • Brain
  • Cardiovascular system
  • Overall body

Since it plays an active role in helping you live a healthy life, your body has the ability to create thiamine itself. But, you can also get it from a diversity of food sources. A few of these include fish, white rice, beans, green peas, breakfast cereals, yogurt, and sunflower seeds. Whole-grain foods such as brown rice also contain high levels of thiamine.

Nowadays, man-made Vitamin B-1 supplementation is a popular way of meeting the body’s needs as well. It is available in both standard and slow-release tablets. You may also find it in injections.

Usually, it is prescribed for the treatment of thiamine deficiencies that result from rare diseases, like:

Congenital Lactic Acidosis

Congenital lactic acidosis refers to a disease caused by mitochondrial DNA mutation. It inhibits the cells from using up energy that leads to excess lactic acid buildup in the body.

Maple Syrup Urine Disease

It is a rare genetic disease in which the affected individual’s body cannot process specific protein building blocks. This condition gives the urine a distinctive sweet odor.

What Does Thiamine Do to Your Body?

As mentioned, water-soluble thiamine is an essential nutrient for the human body. Some of the well-known effects of thiamine include healthier skin, eyes, and hair. However, the health benefits of the B-1 vitamin go deeper than this and are spread throughout the body.

Glucose Conversion

The fundamental purpose of thiamine is to help cells perform glucose metabolism. This is the process where food gets converted into energy. Glucose can be metabolized from any of the macronutrients including carbohydrates, protein, and even fat.

Vitamin B-1 quickens this process by contributing to the production of ATP (adenosine triphosphate). ATP molecules are powerhouses that transport energy and releases it when needed by the body.

Neurotransmitter Production

Neurotransmitters are the body’s chemical messengers. They are molecules present in the nervous system that transfer messages between neurons. They also transfer messages from neurons to muscles.

Acetylcholine is a vital neurotransmitter found in the nervous system. It improves memory and cognitive function. It also helps in the regulation of muscle control and behavior.

Thiamine plays a significant part in its production. It combines with acetyl-CoA to create acetylcholine. As a result, it enhances the overall nervous system function.

Impact on Brain Activity

Thiamin has several derivatives, or chemicals that can be made from it, that impact brain activity positively. These include: thiamine diphosphate and thiamine triphosphate.

The thiamine diphosphate serves as a cofactor for enzymes that help in the conversion of glucose. Meanwhile, the thiamine triphosphate exhibits distinct properties at the neural membrane. Altogether, these thiamine derivatives improve memory, concentration, and overall mental health.

Heart Health Improvement

Since vitamin B-1 helps with the production of acetylcholine, it also minimizes the risk of heart attacks and diseases. The neurotransmitter improves nervous system communication which means that it also enables the proper functioning of the heart.

Pyruvate Metabolism

Pyruvate is a key molecule in the energy metabolism pathway, also called the Krebs cycle. It can be changed into various nutrients by using thiamine. For example, it is converted to carbohydrates through gluconeogenesis and fatty acids via acetyl-CoA.

Effect on Sepsis

Sepsis is the extreme-level response to an infection initiated by the body. It occurs when the infection in your body triggers a chain reaction. Usually, these infections start in the skin, lungs, urinary tract, or gastrointestinal tract.

Although sepsis is a body response, it can be fatal when you have extremely low levels of both thiamine and Vitamin C. It can lead to shock which is when small blood clots form throughout the body. These blood clots stop blood flow which lowers oxygen levels in cells.

Because of all this, people either experience kidney failure or death. Having sufficient Vitamin C and thiamine content reduces the likelihood of death from sepsis.

Antidepressant & Stress Agent

Thiamine also holds a reputation as an anti-stress vitamin. The vitamin relieves stress and stabilizes mood and can also boost the immune system which eases stress.

Plus, thiamine fights against depression symptoms, such as gloomy feelings and loneliness. However, this benefit is mainly when it is taken in conjunction with antidepressants.
