Thiamine is essential for promoting growth, protecting our heart muscle and for stimulating brain action. You can read about the complete benefits of vitamin b1 here.

Daily Requirement Of Vitamin B1

The recommended daily intake for adults over 18 year old is 1.2 mg for men and 1.1 mg for women. For children the recommended daily intake is .2 mg per day and the requirement steadily increases with age. Pregnant women should increase their daily intake of vitamin B1 to 1.4 mg.

Vitamin B1 Deficiency Symptoms

Mild deficiency of vitamin b1 usually goes unnoticed. One of the first symptoms of vitamin b1 deficiency is lack of appetite which is due to lack of proper carbohydrate metabolism. Other mild symptoms include digestive problems due to defective hydrochloric acid production, leg cramps, muscular weakness, hair loss, irritability, difficulties with short term memory, depression and weight loss.

Prolonged thiamine deficiency can lead to feeling of numbness and tingling sensation like pins and needles usually accompanied by pain, constipation, scanty hair, delirium, folic acid deficiency, delusional disorder, diabetic ketoacidosis, swollen hands and feet, chest pain, vertigo, double vision, memory loss and loss of sensation in extremities. Beriberi and wernicke’s encephalopathy are the two common diseases associated with vitamin b1 deficiency.


There are two types of beriberi: Wet beriberi and dry beri beri. Wet beriberi affects the heart and the circulatory system leading to heart failure. Heart failure due to cardiac enlargement is the common cause of death in beri beri. The right side of the heart fails due to odema (water retention) which leads to swelling. Dry beriberi affects the nervous system leading to diminished reflexes, depression and host of other neurological problems.

Also people with nervous problems like anxiety, insomnia, irritability and depression will find their mood improving consuming a vitamin b1 rich diet.

If you are suffering from prolonged periods of the symptoms mentioned above, I would highly suggest you get a blood test done to determine your vitamin b1 levels and then take vitamin b1 supplements after consulting a physician till your vitamin b1 levels reach the optimum levels. Once it reaches the optimum level, you can stop taking the supplement and maintain it by just consuming vitamin b1 rich foods.
