Vitamin B-1 (thiamine)

March 22, 2017

B Vitamins are a group of 8 water soluble vitamins that are essential for certain bodily functions, such as metabolism, energy production, and nervous system function.

  • Vitamin B-1 (thiamine): Required for the production of enzymes involved in glucose metabolism and therefore involved in providing energy to the brain from the food you eat. This vitamin helps to stabilize moods and aids with memory. The body uses thiamine to make adenosine triphosphate which transports energy within cells. There are no risk factors associated with thiamine consumption. Food sources include: pork, poultry, peas, nuts, soybeans, dried beans, lentils, legumes, whole grains, bread, rice, and yeast. Thiamine deficiency can be increased by certain practices such as: drinking excessive amounts of coffee and tea, chewing tea leaves or betel leaves, and eating raw fish and shellfish. Thiamine deficiency is rare and can cause health problems such as Beriberi (a condition that affects breathing, eye movements, heart function, and alertness), and Wernicke-Korsakoff syndrome (where Wernicke’s disease affects the nervous system causing visual impairments, lack of muscle coordination, and mental decline, and Korsakoff syndrome permanently impairs memory functions in the brain. A main cause of such deficiencies is alcoholism.


Vitamin B-1:

  • Improves energy production
  • Improves cardiovascular health, along with muscle and nerve health: This is due to the production of acetylcholine, a neurotransmitter which relays messages to the muscles and nerves. Deficiency can cause irregular heartbeat, and congestive heart failure
  • Prevents cataracts and improves overall eye health: When used in conjunction with fatty acids such as Omega-3 and Omega-6, this vitamin aids with the prevention of cataracts
  • Improves brain function and memory: This vitamin improves concentration and memory, helping to ward off diseases such as Alzheimer’s and dementia
  • Halts the progression of Multiple Sclerosis and Bell’s Palsy
  • Alleviates stress
  • Strengthens and improves overall nerve function: This occurs due to the production of Myelin sheaths which are the protective covering of the nerves
  • Anti-aging properties: Vitamin B-1 acts as a powerful antioxidant, which helps protect the body from wrinkles, age spots, and other age related conditions
  • Improves digestion: Vitamin B-1 aids with the secretion of hydrochloric acid, which is essential for the breakdown and digestion of food
  • Improves appetite
  • Aids with red blood cell production
  • Boosts immunity: Vitamin B-1 strengthens and maintains the muscles along the walls of the digestive tract. This aids in the proper absorption of nutrients from the digested foods, and results in a higher immunity, leaving you less likely to become sick
  • Treats alcoholism: Alcoholism can cause deficiencies in Vitamin B-1, so supplements can reverse some of the effects of Wernicke-Korsakoff syndrome which is a result of Vitamin B-1 deficiency. It can also decrease symptoms of alcohol withdrawal
  • Improves and stabilizes mood
