Calcium and Vitamin D


Calcium is essential for the development and maintenance of strong bones and teeth (also for normal blood clotting, nerve function and enzyme activity).It is an essential nutrient throughout life for everyone.

A poor calcium intake prevents bones from develop normally or become weak causing osteoporosis (brittle bones).

Sources of calcium include

milk, cheese, yogurt and other dairy foods
dairy free/vegan milk, yogurts and cheese with added calcium
sardines and pilchards (only if eating the bones)
green leafy vegetables
soya beans/tofu
bread and foods made with calcium fortified flour

If you are unable to get enough calcium from your diet then calcium supplements are available


Vitamin D
works alongside calcium to build and maintain strong bones and the recommended dose required is 10ug (400 International Units IU) daily.

A lack of vitamin D can lead to bone deformities such as rickets in children, and bone pain and osteoporosis in adults. We get most of our vitamin D from sunlight on our skin (which is why it is called the sunshine vitamin) but if you don’t go outside much, wear sunscreen or are covered up, this vitamin D is unavailable to you.


Vitamin D from foods

oily fish – such as salmon, sardines and mackerel
fortified fat spreads
fortified breakfast cereals
powdered and fresh milk /dairy
vitamin D supplements
