Vitamin B1 (Thiamine)

USE: Vitamin B1, also called thiamine, is one of 8 B vitamins. All B vitamins help the body convert food (carbohydrates) into fuel (glucose), which is used to produce energy. These B vitamins, often referred to as B complex vitamins, also help the body metabolize fats and protein. B complex vitamins are needed for healthy skin, hair, eyes, and liver. They also help the nervous system function properly, and are needed for good brain function. All B vitamins are water-soluble, meaning that the body does not store them.
Like other B complex vitamins, thiamine is sometimes called an "anti-stress" vitamin because it strengthens the immune system and improves the body's ability to withstand stressful conditions. It is named B1 because it was the first B vitamin discovered.
SOURCE: Good sources of Vitamin B1 include beef, pork, liver, legumes, fish, poultry, dairy, yeast, whole-grain breads, pasta and nuts.
