Vitamin B1

What is Vitamin B1?

Vitamin B1, also known as thiamine, is a water-soluble vitamin that plays a crucial role in the body's carbohydrate metabolism. It is necessary for converting carbohydrates into energy, making it important for both physical and mental functions of the body.

How does it work in the body?

Thiamine acts as a coenzyme in several metabolic processes, particularly in the conversion of glucose to energy.

Scientific benefits

According to a study published in the American Journal of Clinical Nutrition, thiamine deficiency is linked to neurological disorders, which can lead to conditions such as Wernicke-Korsakoff syndrome.

• Support for the nervous system: Thiamine helps produce neurotransmitters necessary for normal nerve function.

Dosage and recommendations

The recommended daily dose of vitamin B1 varies depending on age, sex, and lifestyle. For adults, the recommended dose is approximately 1.1 mg per day for women and 1.2 mg per day for men. Pregnant and breastfeeding women may require higher doses. It is always wise to consult a doctor or dietitian before starting supplements.

Best sources and forms

Vitamin B1 is naturally found in many foods. Some of the best sources include:

• Whole grain products such as bread and pasta
• Beans and lentils

It is also possible to take vitamin B1 as a supplement in the form of thiamine or thiamine mononitrate. These supplements can be useful for people with increased needs or those who have difficulty obtaining enough through diet.

Side effects and warnings

Vitamin B1 is generally considered safe when taken in recommended doses. Excessive intake of thiamine through supplements is rare and may cause mild side effects such as headache, irritability, or allergic reactions in rare cases. Individuals with certain medical conditions should consult a doctor before starting supplements, especially if they have kidney problems.
