1. Energy Metabolism: Vitamin B1 plays a key role in the metabolism of carbohydrates, which are the body’s main source of energy. It helps to convert glucose into usable energy and also plays a role in the metabolism of fats and proteins.
2. Nervous System Function: Vitamin B1 is important for the proper functioning of the nervous system. It helps to maintain the myelin sheath, which is the protective covering around nerve cells, and also plays a role in the synthesis of neurotransmitters, which are the chemicals that transmit messages between nerve cells.
3. Cardiovascular Health: Some studies suggest that vitamin B1 may be beneficial for cardiovascular health, as it helps to lower levels of a molecule called homocysteine, which is associated with an increased risk of heart disease.

1. Whole Grains: Whole grains, such as brown rice, quinoa, and whole wheat bread, are good sources of vitamin B1.
2. Legumes: Legumes, such as lentils, black beans, and kidney beans, are also good sources of vitamin B1.
3. Nuts and Seeds: Nuts and seeds, such as sunflower seeds, pine nuts, and pecans, contain vitamin B1.
4. Meat: Pork, Beef and Chicken  are a good source of vitamin B1

Vitamin B1 supplements are also available in various forms, including tablets and capsules. The recommended daily intake of vitamin B1 for adults is 1.1-1.2 mg per day, although higher amounts may be needed for certain populations, such as pregnant and breastfeeding women. It’s important to obtain vitamin B1 from food sources whenever possible, as supplements may not provide the same health benefits as whole foods.
