NCT01617044

Brief Summary

A double-blind randomized controlled trial comparing iron plus vitamin C plus probiotic (lactobacillus plantarum 299) to iron plus vitamin C plus placebo in correcting the iron deficiency in children with Restless leg syndrome (RLS) and iron deficiency. One hundred children with diagnosis of RLS will be recruited over a two- year period.
