IQ is largely hereditary (~70%, IIRC) and polygenic. This mean that attempting to “cure” it by anything short of major genetic engineering will have quite limited upside.
It is worth pointing out that the heritability estimates are determined from current variation, and thus are only weakly predictive of what interventions are possible but unknown. (I do expect that if there were an easy way to make improvements here, we would know about it already, but it’s very possible that there are hard ways to do this.)
