What is Vitamin b1?
Thiamine or thiamin or vitamin B1 named as the "thio-vitamine" ("sulfur-containing vitamin") is a water-soluble vitamin of the B complex. First named aneurin for the detrimental neurological effects if not present in the diet, it was eventually assigned the generic descriptor name vitamin B1. Its phosphate derivatives are involved in many cellular processes. The best-characterized form is thiamine pyrophosphate (TPP), a coenzyme in the catabolism of sugars and amino acids. Thiamine is used in the biosynthesis of the neurotransmitter acetylcholine and gamma-aminobutyric acid (GABA). In yeast, TPP is also required in the first step of alcoholic fermentation.

Energy metabolism:
As a coenzyme (thiamine pyrophosphate, TPP), it participates in the breakdown metabolism of carbohydrates, fats, and proteins, generating ATP for energy supply.
Neurological protection:
Maintain normal function of nerve cells, promote neurotransmitter synthesis, and improve neurological symptoms such as numbness and pain.
Cardiovascular health:
Regulate myocardial metabolism and prevent beriberi related cardiac disorders such as palpitations and edema.
Digestive system regulation:
Promote gastric juice secretion and gastrointestinal peristalsis, alleviate indigestion and decreased appetite.
Disease adjuvant therapy:
Nutritional support for patients with diabetes nephropathy, chronic obstructive pulmonary disease (COPD), recurrent respiratory tract infection and malignant tumor
