Vitamin B1, scientifically called as “Thiamine”. It is a water soluble vitamin. All living organisms use thiamine, but it is synthesized only in bacteria, fungi and plants. Animals must obtain it from their diet, and thus for us it is an essential nutrient.
Thiamine is one of the 8 B vitamins. These 8 B vitamins are called as B complex vitamins. All the B vitamins help the body convert food into fuel, which is used to produce energy. B complex vitamins are needed for healthy skin, hair, eyes and liver
What are The Functions of Vitamin B1 in the Body?
Vitamin B1 is an essential nutrient, and all the tissues of the body, including the brain, need thiamine to function properly. The body needs B1 to make ATP (adenosine triphosphate) a molecule that transports energy within cells. Like other B complex vitamins, thiamine is sometimes called an “anti-stress” vit6amin because it may strengthen the immune system and improve the body’s ability to withstand stressful conditions.
