Maintaining healthy bones and helping to avoid osteoporosis is an important
issue for many people. There are many ways that people can help themselves:
regular exercise, a balanced diet with an adequate intake of calcium and, for
some people, advice on how to prevent falls which may lead to fracture.
This leaflet was last revised in June 2017.
Calcichew 500 mg contains calcium designed to keep bones healthy. Calcium
is an essential component of bones.
Requirements for calcium increase with age and, although many people obtain
enough calcium from their diet, some people may require a supplement in order
that their body has all the calcium it needs to maintain healthy bones.
What Calcichew 500 mg look like and contents of the pack
The tablets are round, white, uncoated convex and orange flavoured; they may
have small specks.
The tablets are packed in white, plastic bottles of 100 tablets.
People with diets and lifestyles that mean they will obtain less than the
recommended intake of calcium are at risk of weakened bones. Prolonged
lack of adequate calcium intake can lead to the development of osteoporosis, a
condition where bones become weak to a level that minimal trauma (for
example, a fall) can result in a fracture, most typically at the hip, spine or wrist.
