There

are

three

stages

of

iron

deficiency.

The

first

and

most

common

is

having

low

iron

reserves,

a

condition

thattypically

has

no

symptoms.

Fatigue

and

poor

performance

may

begin

to

appear

in

the

second

stage

of

deficiency,

when

notenough

iron

is

present

to

form

the

molecules

of

blood

protein

that

transport

oxygen

to

the

working

muscles.

In

the

third

and

final

stage,

people

often

feel

weak,

tired,

and

out

of

breath

—

and

exercise

performance

is

severely

compromised.Para.8

"People

think

that

if

they're

not

at

the

third

stage,nothing

is

wrong,

but

that's

not

true,"

says

John

L.

Beard,

whohelped

design

the

Purdue

study."You're

not

stage

3

until

your

ir

on

reserves

go

to

zero,

and

if

you

wait

until

that

point,

you're

in

trouble."Para.9

However,

most

people

with

low

iron

reserves

don't

know

they

have

a

deficiency,

because

traditionalmethods

of

calculating

the

amount

of

iron

in

blood

(bychecking

levels

of

theblood

protein

that

transportsoxygen)are

not

sufficient,

Beard

states.

Instead,

it'simportant

to

check

levels

of

a

different

compound,which

indicates

the

amount

of

storage

of

iron

in

theblood.

While

active,

child-bearing

age

women

are

m

ost

likely

to

have

low

iron

stores,

he

notes,"Men

are

notsafe,

especially

if

they

don't

eat

meat

and

have

a

high

level

of

physical

activity."(An

estimated

15

percent

of

male

long

distance

runners

have

low

iron

stores.)Beard

and

other

experts

say

it's

advisable

forpeople

inthese

groups

to

a

yearly

test

to

checkbloodiron

If

levels

are

low,

talk

with

a

physician

to

see

ifthe

deficiency

shouldbe

correctedby

modifying

your

diet

orby

taking

supplements.

In

general,

it's

better

to

undo

theproblem

by

adding

more

iron-rich

foods

to

the

diet,

becauseiron

supplements

can

have

serious

shortcomings.

Supplementsmay

produce

a

of

and

may

bepoisonous

in

some

cases.

The

sources

of

and

the

onlysources

of

of

readily

by

are
