Taking iron supplement causes weight gain
On the contrary, a 2014 study reported that treatment of iron deficiency not only improves hematological parameters but also induces weight loss and boosts metabolism. The study looked at 21 anemic women over the course of four to six months who took iron supplements orally to treat anemia. As a result, the patients reportedly significantly reduced waist circumference, body weight and BMI after treatment compared to their pre-treatment phase.
Vegetarians are candidates for anemia
Being a vegetarian doesn't automatically mean you're going to be anemic. A 2012 study of female vegetarian students found that there is no difference in iron intake between non-vegetarians. White vegetarians could be at risk of anemia if they don't consume enough iron, there are actually iron-rich vegetables to help prevent the onset of iron deficiency: spinach, beans, oatmeal, tofu and black-eyed peas.
Insomnia is a symptom of anemia
Anemia affects the quality of sleep but insomnia is not a direct symptom of anemia.
A lack of iron in the body can cause symptoms such as fatigue and Restless Leg Syndrome (RLS) which affects sleep quality and alertness. Those who suffer from RLS shared a growing urge or sensation to move their legs that worsens at night, which may leave one with disrupted sleep and feeling tired upon waking up.

A healthy diet guarantees good iron levels all the time
Healthy eating habits could sometimes accidentally negatively affect iron intake by accident. For instance, there are natural chemicals called phytates found in nuts, legumes, seeds, grains and soy that may interfere with the absorption of iron. Likewise, polyphenols found in black tea, herbal teas, coffee and wine also interfere with iron absorption.
Hair loss is in no way related to iron deficiency
Surprisingly, hair loss may be connected to iron deficiency. Iron deficiency (ID) is the world's most common nutritional deficiency and is a well-known cause of hair loss.* The condition can be detrimental to overall health as well as to hair health.

Taking iron supplements during pregnancy will make it impossible for the child to suffer from iron deficiency
It is important for a pregnant woman to be adequately nourished with iron supplements. The iron requirement during pregnancy is increased gradually through gestation from 0.8 mg/day in the first trimester to 7.5 mg/day in the third trimester. Throughout the entire gestation period, the average demand for absorbed iron is approximately 4.4 mg/day. The absorbed iron is used to fulfill the fetus' iron requirements and compensate for iron losses at birth.
The newborn's iron status depends on the mother's iron status during pregnancy. Infants born to mothers who have taken iron supplements during gestation have enough body iron reserves for four to six months. However, this reserve depletes after six months of age thus iron-fortified complementary diet or iron supplements of adequate nutritional value becomes a need for infants six months of age and beyond.

Iron supplements darken a baby's complexion
The color of the baby's skin is determined by genes and not by any food or supplements intake.
Menstruation does not lead to anemia
While monthly period isn't a factor in causing anemia, blood loss due to menstruation every month leads to loss of iron in those red blood cells. If monthly iron intake and absorption does not replace the iron lost during the monthly period, one may end up with iron deficiency anemia (IDA). People with heavy menstrual bleeding are more susceptible to IDA. A person is considered to have heavy menstrual bleeding when the menstrual period is typically over 80ml. In case the blood loss is more than 80ml, consult a doctor immediately.
