| Little
is known about how Calcium actually works inside our
body to prevent bone loss. When the level of Calcium
rises in blood, a hormone called Calcitonin encourages
the deposition of Calcium in the bones. This in turn,
protects our skeleton. However, further research is
required to bring out the real story behind the mechanism
involved with the prevention of bone loss.
It is better if we know the exact
amount of Calcium to be consumed, in order to cope
with the problems associated with bone loss. The National
Institute of Health (NIH) says that there are many
Americans, whose Calcium intake is less than even
half the recommended amount essential for building
and maintaining healthy bones. To treat and prevent
Osteoporosis, the NIH has their recommendations of
the amount of Calcium intake –
| Children |
800-1200 mg / day |
| Adolescent
Girls |
1200-1500 mg / day |
Pre-menopausal
Women
( 19 to 50 years old ) |
1000 mg / day |
Older Adults
( 51 to 70 years old ) |
1200-1500 mg / day |
| Older Women |
1500 mg / day, excepting those on Estrogen,
who require 1000 mg / day only.
