Not many people know that iron is the most prevalent nutrient deficiency in the world, with a rate of approximately 10% of the population in developed countries and anywhere from 25 – 50% in developing countries. Wow, those are quite the stats, right? Lets start out explaining this condition by describing some of the facts around anemia. Anemia in general is a reduction in oxygen-transporting capacity of the blood. Red blood cells (RBC’s) are the oxygen-transporters that are made of iron. With iron deficiency, there is an inadequate supply of building blocks to make RBC’s, therefore you are not getting enough oxygen to your entire body.
