Dizzy? It Could Be this Nutrient Deficiency Dr. Janine has identified iron deficiency as a potential cause of dizziness. Iron plays an important role in transporting oxygen and nutrients throughout the body, so if levels are low it can cause dizziness. Eating iron-rich foods or taking a whole-food iron complex without fillers or flow agents to supplement dietary intake may be beneficial for addressing this symptom. #lowiron #irondeficiency #anemia #wellness
