Vitamin B1 Review: What is Vitamin B1?

What is it?

Vitamin B1, also known as Thiamine can be found in numerous food products such as cereal, yeast, beans, grains, meat, and nuts. Vitamin B complexes include folic acid, Vitamin B1 (thiamine), Vitamin B2 (riboflavin), Vitamin B3 (niacinamide or niacin), Vitamin B5 (pantothetic acid), Vitamin B6 (pyridoxine), and Vitamine B12 (cyanocobalamin). Vitamin B1 is commonly used together with other B vitamins, and is found in numerous Vitamin B complex products. However, not all products contain all these ingredients and a few of them may include others like PABA (para-aminobenzoic), biotin, inositol, and choline bitartrate.

Vitamin B1 is commonly utilized to treat problems of digestion including ulcerative colitis (an inflammatory bowel disease (IBD) that causes long-lasting inflammation and ulcers in your digestive tract), poor appetite, and recurrent diarrhea. Some individuals use Vitamin B1 to treat conditions related to decreased levels of Vitamin B1 (or thiamine deficiency syndrome), such as neuritis (inflammation of the nerves) associated with pregnancy or pellagra, and beriberi.

Some individuals use Vitamin B1 for improving learning capacity, maintaining a positive mental attitude, fighting symptoms of stress and anxiety, boosting energy levels, enhancing memory and preventing memory loss, and treating degenerative brain diseases like Alzheimer’s disease. Vitamin B1 can also be used to boost the body’s immune system and improves athletic performance. It treats acquired immune deficiency syndrome (AIDS), heart disease, diabetic pain, aging, alcoholism, cerebellar syndrome, visual problems such as glaucoma and cataracts, canker sores, motion sickness. Other uses of vitamin B1 include preventing the development of cervical cancer, and progression of kidney disease in individuals who are suffering from type 2 diabetes.

Some doctors and other medical professionals give Vitamin B1 shots to patients who have Wernicke’s encephalopathy syndrome (which is a neurological disease characterized by the clinical triad of confusion, eye abnormalities, and the inability to coordinate voluntary movement), coma, alcohol withdrawal, and other thiamine deficiency syndromes in terminally ill individuals.

What benefits does Vitamin B1 give?

  • Vitamin B1 deficiency: Studies show that taking Vitamin B1 by mouth could help treat and prevent vitamin B1 deficiency.
  • Wernicke-Korsakoff Syndrome (Brain disorder associated with Vitamin B1 deficiency): Wernicke-Korsakoff syndrome or WKS is a brain disorder related to decreased levels of Vitamin B1 (thiamine deficiency), which commonly occurs in alcoholic individuals. Studies show that about 30 and 80 percent of alcoholics have low levels of Vitamin B1. Giving shots of Vitamin B1 can help reduce the symptoms associated with Wernicke-Korsakoff syndrome and decreases the risk of developing this type of disease.
  • Metabolic disorders: Administration of Vitamin B1 via oral route is known to treat metabolic disorders secondary to genetic diseases, these includes maple syrup urine disease, Leighs disease, and many more.
  • Kidney disease in individuals suffering from type 2 diabetes: Presence of albumin in the urine is a sign of kidney disease. Recent studies show that taking high levels of Vitamin B1 (100 mg, taken 3 times a day) for about three months could reduce the amount of albumin in the urine in individuals with type 2 diabetes.
  • Dysmenorrhea (painful menstruation): Recent studies concluded that taking Vitamin B1 for about 90 days (3 months) could stop the pain felt during menstruation in girls aging from 12 to 21 years.
  • Cataracts: Having a high dietary intake of Vitamin B1 can lead to decreased risk of developing cataracts.
  • Prevent the occurrence of cervical cancer: Recent studies claim that high intakes of Vitamin B1 both from supplement and dietary sources, along with other Vitamin B complexes such as riboflavin, folic acid, and Vitamin B12 can reduce the risk of precancerous spots on the cervix.

Special Precautions and Warnings of Vitamin B1

When taken by mouth at appropriate levels, Vitamin B1 was known to be safe. However, in rare cases, skin irritations and allergic reactions can occur. Vitamin B1 is also known to be safe when properly administered by a healthcare provider intravenously (by IV). Vitamin B1 shots is a prescription product that has been approved by the Food and Drug Administration (FDA).

When taken at a dose of 1.4 mg per day, Vitamin B1 is known to be safe and could not cause any harm to pregnant and breast-feeding women. However, there is no enough evidence to prove its safety when taken at higher dose during pregnancy and breast-feeding.

In some individuals who are suffering from liver problems, drink a lot of alcohol, or have various other conditions, Vitamin B1 could not enter the body properly.
