As a nutritionist, I frequently have clients come into my practice and tell me that they’ve been suffering from long-term anemia, most commonly from a deficiency in iron. Many of these people have been told to take an iron supplement, only to experience constipation, nausea, and other digestive distress that causes them to stop taking it. More notably, clients will tell me that they’ve been deficient for their whole life no matter what they have tried before.
Iron deficiency gets all of the spotlight, but other types of anemia also exist and can affect the body in similar ways—causing fatigue, neurological symptoms like brain fog or depression, or dizziness. When we’re anemic, there is a lack of oxygen getting circulated around the body and that can damage different tissues, including the brain. In fact, long-term deprivation of oxygen to the brain can lead to neurodegeneration and increase your risk for cognitive decline. However, many people who are anemic don’t realize that it's linked to their symptoms, and others aren't properly tested to determine if they're truly anemic and what the cause is.
