The B vitamins are a group of eight
individual vitamins, often referred to as the B-complex vitamins.
Polish
chemist Casimir Funk In 1912 conceived the word vitamin. Funk also isolated
vitamin B1 (thiamine) from rice. This was determined to be one of the vitamins
that prevented beriberi, a deficiency disease marked by inflammatory or
degenerative changes of your nerves, digestive system and heart.
Vitamins
are organic (carbon containing) molecules that mainly function as catalysts for
reactions within your body. A catalyst is a substance that allows a chemical
reaction to occur using less energy and less time than it would take under
normal conditions. If these catalysts are missing, as in a vitamin deficiency,
normal body functions can break down and make you susceptible to disease.
Your
body requires vitamins in tiny amounts (hundredths of a gram in many cases). We
get vitamins from these three primary sources:
-
Foods
-
Beverages
-
Your body
(Vitamin K and some of the B vitamins are produced by bacteria within
your intestines, and vitamin D is formed with the help of ultraviolet
radiation, or sunshine, on the skin.)
Vitamins
are either fat-soluble or water-soluble. The fat-soluble vitamins are A, D, E
and K. These vitamins accumulate within the fat stores of your body and within
your liver. Fat-soluble vitamins, when taken in large amounts, can become toxic.
Water-soluble vitamins include vitamin C, and the B vitamins. Water-soluble
vitamins taken in excess are excreted in the urine but are sometimes associated
with toxicity. Both the B and C vitamins are also stored in your liver.
The
B-complex vitamins are actually a group of eight vitamins, which include
thiamine (B1), riboflavin (B2), niacin (B3), pyridoxine (B6), folic acid (B9),
cyanocobalamin (B12), pantothenic acid and biotin.
These
8 B vitamins are essential for:
-
The breakdown of
carbohydrates into glucose thus providing energy for your body
-
The breakdown of fats
and proteins which helps the normal functioning of your nervous system
-
Muscle tone in the
stomach and intestinal tract
-
Skin
-
Hair
-
Eyes
-
Mouth
-
Liver
The
best way to get your B vitamins is naturally -- through the foods you eat!
The B-complex vitamins are found in brewer's yeast, liver, whole-grain
cereals, rice, nuts, milk, eggs, meats, fish, fruits, leafy green vegetables and
many other foods.
B
vitamins are essential for an astonishing array of life functions and most of us
will get all of the B vitamins we need by eating a well-balanced diet.. Some
people swear by a B-complex supplement every day, but based on the wide variety
of foods containing these vitamins, its not always necessary. For a more
detailed list of all the B vitamins check out my book ‘Get Fit Stay Fit’
