Thiamine (Vitamin B1) Supplement Benefits and Dosage
Find out the benefits of thiamine (also known as vitamin B1), and why it’s important for braincare.
Thiamine, also known as vitamin B1 is an essential vitamin, which everyone needs. It helps with processing food into energy and is used by every tissue in the body. In this article, we’ll go through what thiamine is, vitamin B1 functions in our bodies, what the benefits are, and what the symptoms of low levels.
What is thiamine?
Thiamine is a water-soluble nutrient. It plays a vital role in metabolism, helping the body break down and release energy from food. It’s also important in maintaining the health of the nervous system.
It can’t be stored in the body, and therefore we need to get thiamine from an outside source, every day. Vitamin B1 is present in several common foodstuffs, such as whole grains, peas, nuts and lean pork.
Typically, it hasn’t been considered a nutrient that we are often deficient in. However, we conducted a vitamin deficiency study to establish levels of 5 different B vitamins, and found that 71% of participants were deficient or borderline deficient in B1.
Thiamine (vitamin B1) dosage
The nutrient reference value (NRV) is around 1.2mg per day. The NRV is really the minimum amount and higher doses have been shown to be beneficial.

The benefits of thiamine
As we mentioned above, thiamine is one of the essential vitamins that we all need. So what is thiamine used for? It’s used by every cell in the body. Among its most important benefits, vitamin B1 function is:
Essential for energy release.
Important in the growth, development, and function of cells.
Key to maintaining the health of the nervous system.
There have also been studies that suggest high thiamine levels are beneficial to mental health.
What are low thiamine symptoms?
In its early stages, low thiamine can lead to weight loss, confusion, and short-term memory loss. If left untreated over a long period of time, it could result in cardiovascular symptoms, such as an enlarged heart.
Thiamine and alcohol addiction
Misuse of alcohol can damage the body and mind in complex ways, including the depletion of essential vitamins and nutrients. Thiamine (vitamin B1) functions include processing proteins, fats, and carbohydrates to be used as energy by the heart and brain, so not getting enough B1 can severely affect the body.
A thiamine deficiency can be caused by excess drinking in two ways:
A lack of vital nutrition from a poor diet.
By damaging the stomach lining.
Essential for brain function, one of the first signs of low vitamin B1 is confusion, delirium, and memory loss.
Are there any side effects to thiamine?
There aren’t any known side effects to thiamine, in any quantity. That means that there’s no established safe upper limit (SUL).
