The research suggests that the NHS could save approximately £200 per pregnant woman if iodine supplementation was introduced in the UK. 
In light of the published findings, the RCM has said manufacturers should start introducing the recommended iodine levels in their supplements.
Commenting on the research, Director of Midwifery at the RCM, Louise Silverton said: “The importance of adequate iodine in pregnancy has been known for some time and this study provides additional supportive evidence. This paper also models the savings if the effects of low iodine levels on the brain and other development are prevented.
“One must not forget what lies behind the financial costs of the effects of insufficient iodine during the foetal period, infants, children and adults who fail to meet their cognitive potential.”
While iodine is found in dairy and various seafood, the amount could still be insufficient for expecting women, therefore supplements are recommended.
The RCM says “the time is right” for manufacturers of supplements to introduce the recommended iodine intake into their formulae.
