Hemoglobin Oxygenates Your Blood

Hemoglobin is a very important protein that's found in your red blood cells. It contains iron that can bind oxygen and help oxygenate tissues throughout the body and the brain. Hematocrit is part of the complete blood count (CBC).

Hemoglobin is responsible for carrying 98% of oxygen in circulation. Alterations or depletion of hemoglobin can severely impair oxygen delivery to cells and tissues.

Low hemoglobin is a sign of anemia that can be caused by blood loss or nutrient deficiencies including insufficiency of iron, folate, or vitamin B12. Suboptimal hemoglobin should be monitored and addressed.

Elevated hemoglobin may be associated with dehydration or testosterone therapy.
