Vitamin B1 works as a coenzyme in some types of metabolism, such as glycolysis and the citric acid cycle, which means it is deeply involved in energy production. Notably, vitamin B1 controls the activity of pyruvate dehydrogenase, an enzyme involved in sugar metabolism, thus vitamin B1 deficiency makes it harder to turn sugars into energy. Pork, whole grains, fish eggs, and eel are all rich in vitamin B1.

About vitamin B1
Is it true that garlic oil increases vitamin B1 absorption?
Allicin, an aromatic substance found in garlic, combines with water-soluble vitamin B1 to form a new fat-soluble compound called allithiamine. Because allithiamine is absorbed more readily than vitamin B1 in the digestive tract, this results in better vitamin B1 absorption.
