Iron

Function
An essential nutrient because it is part of blood cells, which carry oxygen to all body cells. It also makes up part of many proteins and enzymes in the body.

Overconsumption Syptoms
It is unlikely that iron toxicity can develop from an increased dietary intake of iron alone. Iron supplements can cause side effects such as nausea, vomiting, constipation, diarrhea, dark-colored stools and abdominal pain.

Deficiencies
Initial symptoms of iron deficiency anemia are fatigue and lack of energy. Dizziness, weight loss, and lowered immunity can also occur.
