Additional Information
Calcichew Forte 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.

Pregnancy, breastfeeding and fertility
If you are pregnant or breast-feeding, think you may be
pregnant or are planning to have a baby, ask your doctor or
pharmacist for advice before taking Calcichew Forte.
During pregnancy the daily intake should not exceed 2500
mg calcium (including food and supplementation). If you are
pregnant, you may use Calcichew 500 mg in case of a
calcium deficiency.
Calcichew Forte can be used during breastfeeding. Calcium
passes into breast milk.
Driving and using machines
Calcichew Forte has no known influence on the ability to
drive or use machines.

Calcichew Forte contains sorbitol (E420) and isomalt
(E953): if you have been told by your doctor that you
have an intolerance to some sugars, talk to your doctor
before taking this medicine. May be harmful to teeth.

Calcichew Forte has been designed to give people, whose
intake of calcium is low, a boost to the recommended
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) 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.
