Thiamine (Vitamin B1): Benefits, Deficiency & Supplements

Thiamin, also known as vitamin B1, is a member of the B vitamins. It is found in many foods. Thiamin helps the body’s cells breakdown carbohydrates to form  sufficient energy for the brain, nervous system and muscles.

Some great sources of Thiamine include;

  • Eggs
  • Whole grain
  • Cereal 
  • Beans
  • Peas
  • Beef steak 
  • Pork trout 
  • Legumes




Thiamine is necessary for growth, development and function of  cells. It helps prevent complications in the nervous system, brain, muscles, heart, stomach, and intestines. 

Consuming thiamine rich foods or supplements can help prevent beriberi (thiamine deficiency).




Thiamine deficiency refers to the reduced levels of thiamine intake. It affects a number of bodily functions.

A more severe form of thiamine deficiency is called Beri-beri, and according to research, this condition can also be passed through gene.

There are two main types of beri-beri in adults : wet beri-beri, which affects the cardiovascular system and dry beri-beri, which affects the nervous system.

Other types are Infantile beri-beri that  affects the babies of malnourished mothers and gastrointestinal beri-beri that affects the digestive system and other bodily systems.

Symptoms may occur with those of Wernicke’s encephalopathy, a primarily neurological thiamine-deficiency related condition, and may include;

  • Muscle weakness 
  • Loss of appetite 
  • Nausea or Vomiting 
  • Weight loss
  • Fatigue 
  • Confusion 
  • Memory loss
  • Edema
