Additional Information
Calcichew 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.
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.
Calcichew have been designed to give people, whose intake of calcium is
low, a boost to the recommended amounts.
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.

The National Osteoporosis Society (NOS) in the UK is national charity
dedicated to improving the diagnosis, prevention and treatment of
osteoporosis. The NOS and IOS offer support to people with
osteoporosis and raise awareness of the importance of healthy bones.
If you are concerned about osteoporosis, please contact the National
Osteoporosis Society, Camerton, Bath BA2 0PJ. Tel: 01761 471 771,
