Vitamin B1 Sources - Vitamin B1 Deficiency
Vitamin B1, a water-soluble vitamin also known as Thiamin, is an important part of the family of B-complex
vitamins. The primary role this vitamin plays inside the body is in the conversion process of blood sugars into
glucose as well as helping the body break down carbohydrates, proteins and fats.
Sufficient levels of Vitamin B1 - Thiamin, also ensure that the nervous system and the cardiovascular system
work optimally. Proper muscular functioning is also dependent on sufficient quantities of this vitamin. The
production of adenosine triphosphate (ATP), which is the body's main source of fuel, could not happen without
Vitamin B1. The heart in particular relies on this fuel supply so that it can keep up with its most important job
of circulating blood throughout the body and supplying the blood cells with oxygen.
Because of its role in helping the heart pump blood, Vitamin B1 - Thiamin can possibly benefit those
individuals suffering from congestive heart failure. Vitamin B1 can also be used to ease the numbness and tingling
often associated with nerve damage. Because of the way this vitamin helps in the energy conversion and heart
pumping processes, it has been known to boost mood and energy levels and alertness.
Water soluble vitamins such as B1 must be continuously
replenished because what the body does not use is eliminated via the urine. If not replenished adequately, a
deficiency can result. But because B1 is found in so many foods, deficiencies are very rare.
Vitamin B1 Sources
Good sources of Vitamin B1 include pork, whole grain cereals, wheat germ, navy beans, kidney beans, garbanzo
beans, peas, peanuts, fish, oysters, whole wheat and rye flour, oranges and orange juice and raisins. The best
sources are found in beef liver and kidneys and in brewer's yeast.
Daily Intake Requirements
A determination as to the most beneficial daily intake of Vitamin B1 has yet to be made. However, since this
vitamin is non-toxic, it really is not possible to consume 'too much'. Remember, as a water soluble vitamin, B1 is
constantly eliminated from the body through the urine. Most experts agree that 1.5 mg each day is sufficient for
men and women.
Vitamin B1 Deficiency
As people age, it is natural for Vitamin B1 levels to start to decline. Aside from the natural deficiency
brought about by age, Vitamin B1 deficiencies are very rare nowadays, but they do exist. Those who consume
excessive amounts of alcohol are most adversely affected as alcohol inhibits the body's ability to properly absorb
this vitamin. Babies that are given formula that lacks Vitamin B1 supplements can also be affected.
The most notable symptom of a Vitamin B1 deficiency is a condition called Beriberi. Symptoms of this condition
include rapid heartbeat, mental confusion, nerve trouble and muscles that gradually begin to waste away. Because
Vitamin B1 plays a significant role in effectively transmitting nerve signals between the spinal cord and
the brain, insufficient amounts of this vitamin can also lead to the development of depression, headaches, nausea,
loss of appetite, nerves that tingle and tiredness.
