Pyridoxine is needed in proportion to the amount of protein consumed.

Function
Beriberi-
The proper chemical name of vitamin K is Phylloquinoe. This vitamin is necessary mainly for the coagulation of blood.
Principle Sources
Spinach
Cabbage
Brussels sprouts
Synthesised by bacteria in the intestine
Fish livers
Alfafa
`
Function
Essential for final stage of prothrombin synthesis in the liver. Therefore it is a necessary factor for the blood-clotting mechanism.
-
Deficiency diseases and Symptoms
Mild deficiency leads to a prolonged blood clotting time.
Serious deficiency means blood fails to clot at all.
The proper chemical name of vitamin E is Tocopherol. The role of vitamin E in human body is not clearly established, but it is known to be an essential nutrient for humans.
Principle Sources
Wheat germ
Brown flour
Liver
Green vegetables
Leafy green vegetables
.
Function
Functions in humans is still unknown.
The vitamin plays some role in forming red blood cells and
muscle and other tissues and in preventing the oxidation of vitamin A and
fats.
.
Deficiency diseases and Symptoms
Anaemia-Increased breakdown of red blood cells.
.
Excess Vitamin E?
Overdoses appear to have lower toxic effects than do overdoses of
other fat-soluble vitamins.
The proper chemical name of vitamin D is Calciferol. For most people enough vitamin D can be made by the action of sunlight on the skin. The light-absorbing molecule found in the skin is made from cholesterol. The active part of the light is ultraviolet light. Normally, stores of vitamin D build up in the liver in the summer months and provide the body's requirements during the rest of the year. Except the principle sources listed below most natural foods are low in vitamin D. So these days vitamin D is added as a supplement to some foods, such as margarine and breakfast cereals.

Liver
Egg yolk
Dairy products
Margarine
Tuna
Vitamin D fortified milk
Made by the action of sunlight on a cholesterol like compound in the skin.
`
Function
Controls calcium absorption from the gut, and concerned with calcium metabolism. Important in bone and tooth formation.
Aids absorption of phosphorus.
`
Deficiency diseases and Symptoms
Rickets-This is the failure of growing bones to calcify. Bow legs are a common children and knock knees in older ones. Deformation of the pelvic bones in adolescent girls can occur which may lead to complications when they are pregnant, and give birth.
`
Osteomalacia-An adult condition where the bones are painful and spontaneous fractures may occur. Here the bones are weakened and soften, becoming less mineralised with calcium and phosphate.
`
Excess Vitamin D?
Excess intake of vitamin D can lead to excess calcium uptake. If the excess cannot all be excreted in the urine it may become deposited in the kidneys where it can cause damage. It is more dangerous for infants than for adults.
Right Amount you Should Take
Regular intakes should not exceed;
35mg per day for teenagers
40mg per day for adolescent
40mg per day for adult women
40mg per day for adult men
50mg per day for pregnant lady
70mg per day for lactating women
Vitamin A
The proper chemical name of vitamin A is
retinol.It is found in food or animal origin. The orange pigment carotene,
familiar in carrots, and similar pigments called carotenes, are found widely in
plants and can be converted to vitamin A during digestion. Vitamin A is a pale
yellow primary alcohol derived from carotene. The structure of carotenes and
vitamin A is particularly well adapted for light absorption. Light brings about
a relativel large change in the structure of retinal, sufficient to trigger the
generation of a nerve impulse.

Function
Controls normal epithelial structure and growth.Deficiency diseases and Symptoms
Skin becomes dry.
Cornea becomes dry
Mucous membranes degenerate.
Poor 'night vision'
Serious deficiency results in complete night blindness or Xerophthalmia
Permanent blindness or Keratomalacia may occur if the vitamin is not present
in the diet.
Excess Vitamin A?
Prolonged consumption of large amounts of vitamin pills can cause
certain matters. Some of the matters are listed below.
Right Amount you Should Take
Regular intakes should not exceed;
6000µg per day for adolescent
7500µg per day for adult women
9000µg per day for adult men
