Calcichew 500mg 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 500mg 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.
For patients in the UK, the National Osteoporosis Society (NOS) is a national charity dedicated to improving the diagnosis, prevention and treatment of osteoporosis. The NOS offers support to people with osteoporosis and raises 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, Fax: 01761 471 104 or email: firstname.lastname@example.org.
