Introduction
Vitamin B1, also known as thiamine, is an essential nutrient that helps the body convert food into energy. Thiamine plays a crucial role in certain metabolic reactions, and the body needs it to form adenosine triphosphate (ATP), which every cell of the body uses for energy. Vitamin B1 is found in both plants and animals, and some of the most common sources include wheat germ, legumes, beef, pork, poultry, whole grain cereals, nuts, and potatoes. A lack of vitamin B1 can lead to serious health consequences including headache, fatigue, irritability, depression and even brain problems. Thiamine deficiency can also cause irregular heartbeat and other cardiovascular conditions.
Vitamin B1 is often called the vitamin of ‘reassurance of the spirit’ because it helps improve concentration, memory and mood. It also supports eye health, enhances digestion, and boosts body immunity. Scientists consider vitamin B1 to be an anti-stress nutrient, which means it helps the body deal with any condition that causes stress. This nutrient is rare to be deficient in, although alcoholics, people with Crohn’s disease, anorexia, and those undergoing kidney dialysis may be at risk.

Dietary Sources
Some of the dietary sources of vitamin B1 (thiamine) include:
Nutritional Yeast: 2 tablespoons provide 9.6 mg (640% DV).
Whole Grains: Including wheat germ, oats and barley.
Legumes: such as black beans.
Meats: especially pork and fish.
Nuts and seeds: Including sesame and sunflower seeds.
Fruits and vegetables: while foods and vegetables do not provide high amounts of thiamine, some exceptions include oranges, peas and asparagus.
Symptoms of Vitamin B1 deficiency:
Loss of appetite
Fatigue
Irritability
Nerve Damage
Headache
Depression
Abdominal discomfort
Difficulties with short term memory
With more severe and chronic deficiency, symptoms may worsen and include:
Beriberi, a condition that causes loss of appetite, muscle weakness and a pricking feeling in the toes and burning in the feet.
Fast heartbeat, low blood pressure (hypotension), and fluid retention.
Brain problems.
It is essential to address vitamin B deficiency promptly, as it can lead to serious health consequences if left untreated.
The treatment option for vitamin B1 deficiency include:
1.Dietary changes: Increasing the consumption of thiamine rich foods such as whole grains, lean meats, legumes, and nuts is a primary step in addressing and preventing thiamine deficiency.
2. Supplementation: In cases of severe deficiency or when absorption is impaired, thiamine supplements may be prescribed by a healthcare provider.
3. Addressing Underlying Conditions: Treating underlying conditions such as alcoholism, malabsorption, or prolonged diuretic use is crucial in managing vitamin B1 deficiency.

In acute cases, intravenous or oral thiamine may be administered until symptoms resolve or improve. For example, in acute crisis, 200mg of intravenous or oral thiamine may be given three times daily until symptoms resolve or at which time the patient should transition to 10 mg/day oral thiamine until expected recovery.
It's important to note that vitamin B1 deficiency can lead to various health issues, including neurological disturbances, heart problems, and digestive issues. Therefore, prompt treatment and prevention are essential to avoid serious consequences.
In addition to the treatment options, adopting a well-balanced diet, refraining from excessive alcohol consumption, and having regular medical check-ups to monitor nutrient levels are important preventative measures.
