Vitamins are feeding substances
that are in very small quantities be found in our feeding and
indispensable for the good functioning of the body. The most cannot make
the body himself. At intensive sporting
the need for vitamins of B complex and
C is larger. For each extra
1000 kcal carbohydrates 0.5 milligrams vitamin B1 and 0.7
milligrams B2. By 100 grams extra proteins: 200
milligrams vitamin C.
Below the different vitamins are described. Too much (much too much) can the functioning of another one a vitamin (strongly) diminish.
In fat-soluble are: A,
D, E and K.
Te much are stored in the liver.
In water
soluble: B-complex and C. Redundant quantities are disappearing with the
urine.

Summary
Tips
Vitamin A (retinol) and carotene 
Is found in:
liver tear, liver, butter and spinach.
Is indispensable for the face capacity. It is necessary for a good
condition of the skin, mucous membranes and our defence system. For
this reason shortages can (night)blindness, dry eyes, lighted
mucous membranes, dry skin and corn cause.
Recommended quantity per day:
vitamin A: 0.45
milligrams and caroteen: 2.4 milligrams.
Provitamin caroteen is converted for 1/6 parts into vitamin a therefore
in sum: 0.85 milligrams.
More necessary at: bright light (winter sport)
and smoke.
Too much: does not occur fast.
Vitamin B complex (B1, B2, B3, B5, B6 and B12) 
It is for
sportsmen and sportswomen important
to get enough vitamins of B-complex. Vitamin
B complex is important for the
combustion of carbohydrates, proteins, fats and the
hormone functioning and for our nervous system. Vitamin B ensures
complete exploiting energy that is
released at the
combustion of carbohydrates: at
each extra 1000 kcal carbohydrates must taken
0.5 milligrams B1 and
0.7
milligrams B2.
Lack can lead to complaints: fast fatigue,
muscle weakness, excitability, concentration lack, sleep problems, skin
problems, flatulence- and bowel complaints, anaemia and the
convalescence after physical effort is less rapidly. It is important for
sportsmen and sportswomen that the prerecording of
B vitamins is optimum, because is energy production (= sporting), proteins metabolism (= muscle
advancement and - convalescence) and hormones must go
well.
Because a large take in of one of the
B vitamins can give a relative shortage of the other
B vitamin,
it is advisable these take vitamins as a vitamin B-complex.
More necessary at: sports, much use sugars, alcohol and
stress.
Prevention of: stress, skin sicknesses.
Vitamin B1 (thiamine) 
Is found in: beer- and baker leaven,
whole-wheat bread.
Necessary at the combustion of carbohydrates and
proteins (if
carbohydrates have been consumed).
Recommended quantity per day: 1.5 milligrams.
Sportsmen and sportswomen: 5-10
milligrams. this quantity
depends on the use on carbohydrates, proteins and alcohol.
Shortage:
metabolism does not complete. Consequence: lack of appetite,
concentration lack. Lack occurs at sportsmen and sportswomen
regularly.
Construction and keeps has considerably what influence.
Vitamin B2 (riboflavin) 
Is found in:
beer- and baker leaven and liver.
Also necessary for the combustion of carbohydrates and
proteins. Also
it has been involved in the maintenance of fabrics and mucous membranes.
Recommended quantity per day: the need has been coupled to the energy
usage 0.44 milligrams by 1000 Kcal.
Therefore 2 à 2.5 milligrams is certainly sufficient.
Shortage: skin
problems at mouth and nose. Also tremble, giddiness and sleep
impairments.
Construction and keeps has considerably what influence.
Vitamin B3 (nicotinamide) 
Also important for sportsmen and
sportswomen: for the combustion processes in the cells.
Recommended quantity per day: the need has been coupled to the energy
usage: minimum 7 milligrams by 1000 Kcal. Shortage does not occur fast.
Shortage: skin deviations, flatulence - and bowel impairments and
disorder feelings.
Vitamin B5 (pantothenic
acid) 
Plays a role in the production of
the adrenal hormones and helps to convert fats,
carbohydrates and proteins into energy. For this
reason B5 is very important also for sportsmen and sportswomen.
Recommended quantity per day: 10
milligrams.
Shortages can
be also the cause of: fatigue, sleep impairments, depressions,
flatulence- and bowel complaints and
lack appetite.
Vitamin B6 (pyridoxine) 
Is found in: leaven, liver, whole-wheat
bread and flesh.
Necessary for all processes of the proteins
metabolism. It is also important
for
the intake of vitamin B12. Furthermore also at
the production of the hormones, blood cells and energy.
Recommended quantity per day: 2 milligrams (more if the intake
proteins of is
larger).
Lack relatively frequently occurs, certainly at sportsmen and
sportswomen. Leading to the characteristic vitamin B lacks: skin - and
mucous membrane deviations, particularly to the nose, eyes and mouth,
with gaps in lips and tongue, and to depressions, migraine,
excitability, giddiness and anaemia.
Vitamin B12 (cyanocobalamin) 
Is found in:
animal foodstuffs such as: flesh, fish, milk and milk products and eggs.
As a coenzyme it has been involved in the production of DNA, the
production of nerve fibres, and normal red blood cells. B12 is
necessary for a good functioning of foliumzuur.
Recommended quantity per day: 1 micrograms.
Shortages lead to: anaemia, demolition of nerve fabrics, depressions,
fatigue and a painful tongue.
Biotine (or vitamin H) 
Is found in: liver, flesh and eggs.
Also in leaven, pod fruit,
and oleaginous seeds.
As a coenzyme it has been involved in the production of energy, and
the shaping of a healthy skin, its, nails and nerves.
Recommended quantity per day: probable 10 micrograms.
The bowel flora makes a large quantity biotine as a result of which it
is not confessed how much necessary is.
Vitamin C (ascorbic
acid)
Is found in:
parsley, oranges, lemons, strawberries, grapefruit, pineapple, spinach,
flower cabbage, broccoli and sprout.
To a lesser degree: tomatoes, chicory and asparagus. In very small
degree: grapes, root, pears apples.
Vitamin C is important vitamin, plays a
distinguished role at many body processes and iron transport. Is essential
for the of metabolism amino acids and the prerecording of iron. Moreover the general condition and capacitance
against infecties improve.
Recommended quantity per day:
100 milligrams per day. For sportsmen and sportswomen quantities of
300-1000 milligrams per day are even recommended.
Shortages cause bleeding and lighted cog flesh, haemorrhage
in skin,
eyes and nose, bad wound cicatrisation, sensitivity for infection, anaemia(as a result
fatigue),
weakness, muscle- and joint pains.
Surplus: with urine it is stopped if the maximum reserve of 10 to12
milligrams has been reached by liter blood. Adults have approximately five
liter
blood (1/13 of the body weight).
Construction and keep has much influence on
quality .
Vitamin D
(ergosterol) 
The prerecording of calcium and
phosphate.
Is found in:
margarine, eggs, fat fish and by our skin is made by sunlight
(especially spring).
Recommended quantity per day: 5 micrograms.
Shortages lead at children to a reduced calcification and the bones. At adults step on pains in
bones, fragile bones and
muscle weakness.
Vitamin E (tokoferol) 
Is found in:
sprout, eggs and margarine.
Is a power antioxidant. Protects muscles, heart
and blood barrels against damage by aggressive radicals. Also it helps to keep
the red blood cells longer intact and raises with that
endurance. The skin helps against old age phenomena.
Recommended quantity per day: 10-15
milligrams (sportsmen and sportswomen
need more).
Shortage: the muscle cells can insufficiently
function.
Lack can also lead to sleep impairments, lack of vitality, concentration
lack and muscle weakness.
Vitamin K 
Is important
for the clotting of blood. Vitamin
K sufficiently in our feeding.
Recommended quantity per day: minimum 100 micrograms.
Shortage: slowed down blood
clotting.

Tips  |
|
· |
At normal activities and ordinary
varied feeding the chance on vitamin shortage is not large. At
sportsmen and sportswomen the energy
use is larger than normal. Because of this
the need for vitamins also increases.
Especially the need for vitamins of complex
B and C larger. That chance at sportsmen and
sportswomen on a shortage is larger, because the larger
energy usage is frequently covered by empty calories such as
sweet,
bands and cola. |
| |
|
|
· |
Who drinks much coffee must ensure
more vitamin B. |
| |
|
|
· |
Stress cost to
many vitamins (especially C). |
| |
|
|
· |
By to cook, steam and roast goes
approximately 40 up to 60 per cent of the present vitamin in food
lost. |
| |
|
|
· |
Vitamin shortage will be just
noticeable after some time. |
| |
|
|
· |
To much vitamins just as evil
as a shortage. |
| |
|
|
· |
At a vitamin B1, and B2 and B6 and
C
shortage decrease the maximum performance capacity and duration
performance. Extra vitamin supplements above the correct quantities
have however no impact. |
| |
|
|
· |
It is dissuaded for example but one
vitamin in a high amount, use because they’re relative shortages of
another one a vitamin can arise. |
