Vitamin B1

Overview 

Vitamin B1, also known as thiamine, is one of the 8 B vitamins and is water-soluble. All B vitamins help the body convert carbohydrates into glucose, which is used for energy. Among the foods in a typical daily diet, brewer's yeast, whole grains, nuts, and sunflower seeds contain the highest amounts of vitamin B1.

B vitamins, also known as B complex vitamins, assist the body in metabolizing fats and proteins. B-complex vitamins are essential for maintaining healthy skin, hair, eyes, and liver. They also support proper nervous system function and are important for good brain health. Most people are not deficient in B1, but alcoholics, people with Crohn’s disease, anorexia, and those on kidney dialysis may experience deficiency. Symptoms of thiamine deficiency include fatigue, irritability, depression, and abdominal discomfort. Individuals with a deficiency often have trouble digesting carbohydrates.
