Ferritin and Iron Deficiency

Mercola: The thing with ferritin is it's a very frustrating, Dr. Mercola, because we have 50 years of disinformation that started in 1972. We've been pummeled with messaging that Ferritin is an indication of iron status. And more often than not, I see people who have normal hemoglobin and maybe some kind of dysregulation in their ferritin. What that's telling me is that there's more organ pathophysiology, particularly around the liver.
