National
Osteoporosis
Foundation’s
Updated
Recommendations
for
Calcium
and
Vitamin
D Intake
July
26, 2007
In
recent
years,
calcium
and
vitamin
D
deficiency
have
been the
topics
of
significant
research
and
professional
debate.
Based on
substantial
research
findings
on
consensus
among
the
leading
experts
on this
topic,
the
National
Osteoporosis
Foundation
(NOF) is
updating
its
recommendations
for
daily
adequate
calcium
and
vitamin
D intake
to the
following
amounts:
Calcium
According
to NOF
recommendations,
adults
under
age 50
need
1,000 mg
of
calcium
daily,
and
adults
age 50
and over
need
1,200 mg
of
calcium
daily.
Vitamin
D
According
to NOF
recommendations,
adults
under
age 50
need
400-800
IU of
vitamin
D3
daily,
and
adults
age 50
and
older
need 800
– 1,000
IU of
vitamin
D3
daily.
Vitamin
D3 is
the form
of
vitamin
D that
best
supports
bone
health.
It is
also
called
cholecalciferol.
Vitamin
D can
also be
obtained
from
fortified
milk,
egg
yolks,
saltwater
fish,
liver
and
supplements.
Role
of
Calcium
Getting
the
daily
recommended
amount
of
calcium,
whether
through
diet,
supplements,
or
combination,
is
essential
to
maintaining
bone
strength
and can
play a
vital
role in
preventing
osteoporosis-related
fractures.
Role
of
Vitamin
D
Vitamin
D plays
a major
role in
calcium
absorption
and bone
health.
Vitamin
D3 is
manufactured
in the
skin
following
direct
exposure
to
sunlight;
however,
there
are many
different
factors
that
affect a
person’s
ability
to make
adequate
amounts
of
vitamin
D.
NOF
revised
its
recommendations
after
careful
consideration
and
review
of a
growing
body of
evidence
that
calcium
and
vitamin
D
deficiency
is
widespread
throughout
the
world as
well as
in the
U.S.,
particularly
in
adults
50 and
older.
NOF will
be
working
in the
coming
months
to
update
its
resources
and
materials.

You Need
to Know
about
Calcium
-Follow
these
tips to
get the
most out
of your
supplement. |

The
advice
is
simple:
to keep
bones
strong,
especially
as you
age, get
enough
calcium
– 1,000
milligrams
(mg) per
day if
you’re
younger
than 50;
1,200 mg
if
you’re
older.
You can
get
calcium
in your
diet by
eating
green
leafy
vegetables;
consuming
low-fat
milk,
yogurt
and
cheese;
or
opting
for
calcium-fortified
juice,
bread
and
cereal.
If you
don’t
get
enough
calcium
in your
diet, be
sure to
take a
calcium
supplement
daily.
But you
may need
to
increase
your
knowledge
about
calcium
to
ensure
your
body
gets
what it
needs.
Calcium
Basics
• Make
sure you
check
the
amount
of
elemental
calcium
in a
supplement;
that’s
what
your
body
will
actually
absorb.
• Take
several
smaller
doses
per day,
because
your
body can
absorb
only 500
mg at a
time.
• Your
body
needs
vitamin
D to use
calcium
most
efficiently,
so look
for a
supplement
that
contains
both.
Calcium
“Cheat
Sheet”
There is
several
different
types of
calcium;
check
out the
chart
below
for the
three
most
popular
types.
Other
kinds,
such as
calcium
gluconate
and
calcium
lactate,
have
very low
amounts
of
elemental
calcium
and are
not
recommended.
Coral
calcium
and
oyster-shell
calcium
products
also are
best
avoided
because
they may
contain
lead.
| Calcium Type |
Pros |
Cons |
Calcium citrate
(Citrical, Solgar) 21% calcium |
Most easily absorbed |
Most expensive; doesn’t contain much elemental calcium |
Calcium carbonate
(Tums, Caltrate, Rolaids) 40% calcium |
Least expensive; has more elemental calcium |
Must be taken with meals or glass of acidic (orange) juice; may cause gas or constipation |
| Calcium phosphate (Posture) 39% calcium |
Does not cause gas or constipation; easily absorbed |
More expensive than calcium carbonate |

Omega 3
(Fish
Oil)
Eating
Fish May
Reduce
Inflammation |
http://www.arthritis.org/eating-fish-to-reduce-inflammation.php
Eating
seafood
with
omega-3s
may
reduce
your
need for
anti-inflammatory
medications.

Talk
about
health
food;
the
kinds of
fish
loaded
with
omega-3
fatty
acids
are good
for
everything
from
heart
disease
to
depression
–
including
arthritis,
according
to
researchers
at
Harvard
Medical
School,
Cambridge,
Mass.
Not only
can
omega-3s
significantly
reduce
joint
pain and
shorten
the
duration
of
morning
stiffness,
but
studies,
such as
those
reported
in the
American
Journal
of
Clinical
Nutrition,
show
that
increased
levels
of
omega-3
fatty
acids
also
have
enabled
people
taking
nonsteroidal
anti-inflammatory
drugs (NSAIDs)
to
reduce
their
dosage
or
discontinue
use.
Adding
about
two
3-ounce
servings
of
seafood
to your
menu
each
week is
a good
way to
increase
your
levels
of
omega-3s
and help
decrease
the
body’s
inflammatory
reaction.
The
highest
levels
of
omega-3
can be
found in
cold-water,
fatty
fish
such as
salmon,
trout,
mackerel,
tuna,
sardines
and
herring.
Many
studies
use fish
oil
supplements
to
increase
intake
of
omega-3s.
If
you’re
averse
to fish
and are
considering
fish-oil
supplements,
check
with
your
doctor
first
for
proper
dosage,
especially
if you
are
taking
blood
thinners.
Omega-3s
from the
Sea
The
United
States
Department
of
Agriculture
recommends
two
servings
a week
(3.5-ounce
portions)
of the
following
fish for
healthy
omega-3
fatty
acids
benefits,
which
can help
reduce
inflammation:
•
Atlantic
salmon
•
Sockeye
salmon
• Lake
trout
• Tuna
canned
in oil
or water
