That Brilliant Vitamin: Vitamin B
Perhaps you first read riboflavin at the back of a cereal box.
Perhaps you first encountered folic acid from your first grade
science teacher. Perhaps you first heard balanced diet from your
mom. All that and more compose Vitamin B which is a group of
eight individual vitamins, often referred to as B vitamins or
B-complex vitamins. Vitamin B promotes normal growth and
development, treats anemia and some types of nerve damage, helps
mental and nervous conditions, improves resistance to infection
and disease, increases appetite and energy, and improves memory.
Vitamin B is also essential for the breakdown of carbohydrates
into glucose, breakdown of fats and proteins, muscles in the
stomach and intestinal tract, skin, hair, eyes, mouth, and liver.
As mentioned earlier, Vitamin B is a group of eight individual
vitamins. These vitamins are thiamine (B1), riboflavin (B2),
niacin, pyrodixine (B-6), folic acid (B-9), cyanocobalamin
(B-12), panthotenic acid, and biotin.
Vitamin B1 or Thiamine is essential for the conversion of
carbohydrates into simple sugars called glucose which produces
energy. This Vitamin B is also essential for the proper
functioning of the heart, muscles, and nervous system. Thiamine
deficiency is rare but often occurs to alcoholics because
alcohol oftentimes interferes with the absorption of Vitamin B
thiamine through the intestines. There are also several health
implications associated with being thiamine deficient. One is
beriberi, a disease characterized by anemia, paralysis, muscular
atrophy, and spasms in the leg muscles. Other disorders
associated with being thiamine deficient is Wernicke's
encephelopathy which causes lack of coordination, Korsakoff's
psychosis which affects short-term memory. Being thiamine
deficient can also affect the mouth resulting to increased
sensitivity of the teeth, cheeks, and gums as well as cracks in
the lips. Vitamin B thiamine can be found in whole-grain
cereals, bread, red meat, egg yolks, and green leafy vegetables.
High doses of thiamine has been found not to cause adverse
health effects and excess of this water-soluble vitamin b can be
excreted.
Vitamin B2 Riboflavin is important in the breakdown of
carbohydrates, and fats and proteins. It is also significant in
the maintenance of the skin and mucuous membrane, the cornea of
the eye, and nerve sheaths. Riboflavin deficiency can cause skin
disorders and inflammation of the soft tissue lining around the
mouth and nose. It can also cause the eye to be hypersensitive
to light. Like Thiamine, Riboflavin is found in whole grain
products, milk, meat, and eggs. This is also excreted because it
is a water-soluble vitamin although a little is stored in the
kidney and liver.
Vitamin B3 Niacin, also known as nicotinamide, is important in
metabolism as well as in the maintenance of healthy skin,
nerves, and gastrointestinal tract. Niacin deficiency can result
to a disease called pellegra. The symptoms of pellegra are
sometimes called "Three Ds" - diarrhea, dermatitis, and
dementia. The mouth is also affected by pellegra which causes
the inside of the cheeks and tongue to become red and painful.
Vitamin B3 can be found in dairy products, poultry, fish, lean
meat, nuts, and eggs. Niacin can also be prescribed in higher
doses as drugs to help lower cholesterol but this can cause side
effects such as flushing of the skin , itching, headaches,
cramps, nausea, and skin eruptions.
Vitamin B6 Pyridoxine which is also known as pyridoxal phosphate
is used in the production of red blood cells and in the
biochemical reactions involved in the metabolism of amino acids.
It is also responsible in the synthesis of of antibodies in the
immune system and helps maintain normal brain function. Vitamin
B6 deficiency is rare except for alcoholics. It causes skin
disorders, abnormal nervous system known as neuropathy,
confusion, poor coordination, and insomnia. Inflammation of the
lips, tongue and the rest of the mouth are oral symptoms of
Vitamin B6 deficiency. Vitamin B6 can be found in organ meats,
brown rice, fish, whole grains, fortified breads and cereals,
and legumes.
Vitamin B9 Folacin is a Vitamin B-complex which interacts with
Vitamin B12 for the synthesis of DNA which is important for all
cells in the body. Folacin, a combination of Vitamin B12 and
Vitamin C, is essential in the breakdown of proteins and
production of red blood cells, tissue growth, and cell function.
It also stimulates appetite and formation of digestive acids.
Folacin deficiency causes anemia, stunted growth, and irritation
of the mouth. Alcoholics, the malnourished, the poor, the
elderly, and those who have certain illnesses are usually the
ones found to be Vitamin B9 deficients.Vitamin B9 is found in
legumes, citrus fruits, whole grain cereals, and green
vegetables.
Vitamin B12 Cyanocobalamin like all other Vitamin B-complex is
essential in the processing of carbohydrates, proteins, and
fats. Vitamin B12 is also needed for maintenance of our nerve
sheaths, activates amino acids during protein formation, and
helps in the perpetuation of cells and fomation of new ones. One
interesting thing about Vitamin B12 is that it cannot be
absorbed by the body unless combined with mucoprotein made in
the stomach. Once Vitamin B12 attaches to the mucoprotein, it
travels in the small intestine to be absorbed by the body.
Vitamin B12 deficiency is recurrently seen in strict vegetarians
who do not take vitamin supplements. A deficiency can also cause
pernicious anemia which in turn causes weakness, numbness of the
extremities, and fever.
Pantothenic acid and biotin are the last two Vitamin
B-complexes. Pantothenic acid is used in the breakdown of
carbohydrates, lipids, and amino acids while biotin functions as
a coenzyme in carboxylation reactions. There is no known
disorder associated with pantothenic acid deficiency while
deficiency in biotin can cause scaly dermatitis which is a skin
disorder. Pantothenic acid is mainly found in meat, legumes, and
whole-grain cereals while abundance of biotin is found in beef
liver, mushrooms, and egg yolk.
