Vitamin B1 helps the body digest and absorb nutrients and convert them into energy, a process called the metabolism of fats, proteins, and carbohydrates. Many enzymes like digestive enzymes, which break down food in the digestive tract, need vitamin B1 to produce and activate.
So a deficiency of this vitamin can cause digestive problems such as anorexia, overeating, Nervous, difficulty digesting food, and so on.
Vitamin B1 helps the transmission of nerve messages from the central nervous system to regulate muscle movements and memory. Vitamin B1 is one of the essential substances for the brain and central nervous system that its deficiency is associated with psychological symptoms such as depression, forgetfulness, and anxiety.
Vitamin B1, in conjunction with neurotransmitters in the brain, is responsible for regulating appetite, which together creates a feeling of hunger or satiety after eating.

Vitamin B1 provides nutrients for the health of nerve cells. The outer layer of nerve cells contains vitamin B1 so that their activity is highly dependent on this vitamin.
