25 Oct 2022 --- A US-based team of researchers from the University of California is revealing that the rate of iron supplementation in infants may actually be harmful and should be reevaluated to prevent injuries, adverse reactions and possible death. The study authors state that infants are highly susceptible to both iron deficiency (ID) and iron deficiency anemia (IDA). This condition can cause uncorrectable problems with cognition and neurodevelopment.
