Iron, a trace mineral, supplies energy to every cell in the body. It is a
key component of hemoglobin, the blood's oxygen-carrying pigment. Iron is
also found in myoglobin, which supplies oxygen to muscles, and in compounds
that keep the immune system strong. This mineral is critical to sharp
mental functioning. Even slight deficiencies in iron can shorten attention
span and make concentration difficult.*
Normally, the body gets sufficient amounts of iron from the foods you eat.
It manages to self-regulate itself, storing amounts you will need by
automatically absorbing more iron when the need is high, and less when
levels are adequate. Nonetheless, iron deficiency is still a significant
public health problem. It can occur during periods of rapid
growth--infancy, adolescence, and pregnancy--which increase the body’s
demand for this mineral. In addition, women who menstruate heavily tend to
have lower iron levels.*
A chronically iron-poor diet or any condition characterized by prolonged
bleeding (even of small amounts), such as ulcers, hemorrhoids, and rectal
polyps, can lead to iron-deficiency anemia. Many people develop this type
of anemia, for instance, as a consequence of an NSAID-related ulcer, or one
caused by months or years of regularly taking aspirin, ibuprofen, or other
non-steroidal anti-inflammatory drugs (NSAID).*
Government statistics indicate that 11% of women under age 50 and 9% of
adolescents are iron-deficient. Dieters, some vegetarians, and endurance
athletes may also develop iron deficiency due to the unique demands on
their bodies.

Potential Health Benefits:
When iron stores are too low, the lack of oxygen produces debilitating
fatigue, weakness, and shortness of breath. Iron supplementation can
correct the condition. (The underlying causes of bleeding should be
medically treated as well, of course.) Bear in mind that a wide range of
other medical conditions and other nutritional deficiencies, such as a
shortage of folic acid might also cause these symptoms.*
Signs of iron deficiency anemia include:
-
Feeling tired and weak - PMS
-
Decreased work and school performance
-
Slow cognitive and social development during childhood
-
Difficulty maintaining body temperature
-
Decreased immune function, which increases susceptibility to infection
-
Glossitis (an inflamed tongue)
Who may need extra iron to prevent a deficiency?
Three groups of people are most likely to benefit from iron supplements:
people with a greater need for iron, individuals who tend to lose more
iron, and people who do not absorb iron normally. These individuals
include:
-
Pregnant women
-
Preterm and low birth weight infants
-
Older infants and toddlers
-
Teenage girls
-
Women of childbearing age, especially those with heavy menstrual losses
-
People with renal failure, especially those undergoing routine dialysis
-
People with gastrointestinal disorders who do not absorb iron normally
- Those who have undergone gastric surgery
- People with heart failure
- Those taking iron-depleting medications, such as those used to reduce stomach acid
- People regularly partaking in heavy exercise
- Those following a vegetarian or vegan diet
- People with blood disorders, such as thalassemia or sickle cell anemia

condition characterized by prolonged bleeding such as ulcers, hemorrhoids,
and rectal polyps, can lead to iron deficiency. This product is highly
absorbed and non-constipating.
What foods provide iron?
There are two forms of dietary iron: heme and nonheme. Heme iron is derived
from hemoglobin, the protein in red blood cells that delivers oxygen to
cells. Heme iron is found in animal foods that originally contained
hemoglobin, such as red meats, fish, and poultry. Iron in plant foods such
as lentils and beans is arranged in a chemical structure called nonheme
iron. This is the form of iron added to iron-enriched and iron-fortified
foods. Heme iron is absorbed better than nonheme iron, but most dietary
iron is nonheme iron. A variety of heme and nonheme sources of iron are
listed in Tables 1 and 2.
