What are vitamins?
Complex organic substances that are needed in very small amounts for many of the
processes carried out in the body.
Minerals and vitamins are micro nutrients- needed in small amounts to keep the
body working properly
Fat Soluble Water Soluble
Vitamin A Vitamin C
Beta-Carotene/ Retinol Ascorbic acid
Vitamin D Vitamin B group
Cholecalcifoerol (see below for scientific name)
FAT SOULUBLE VITAMINS- Are stored in the body, in the liver so we don't
need a daily supply
WATER SOLUBLE VITAMINS- Dissolve in water and cannot be stored in the
body so we need a daily supply.
Although we only need these micro-nutrients in small amounts they are essential.
Fat Soluble
1. Vitamin D
Vitamin D is essential for the formation of strong and healthy bones and teeth as
it is needed to absorb calcium.
Other nutrients such as phosphorus and calcium are also needed for
Vitamin D to work.
A shortage of Calcium and Vitamin D in children causes Rickets.
What are the symptoms of Rickets?
This is a bone disease where the bones are weak, this causes
Bow legs
Bent spine
Badly deformed bones.
The adult version of Rickets is called osteomalacia, which leads to pain and muscle
This is a condition of weakening bones and thinning of the bones.
The bones fracture and break easily.
This is caused by a lack of calcium and a lack of Vitamin D to absorb the calcium.
