Constipation
Supplements studied for constipation.
Overview
Constipation has several supplements with usable trial evidence. Magnesium salts (citrate, hydroxide, oxide, sulfate) can relieve acute and chronic idiopathic constipation at studied oral doses. Inulin increases bowel movement frequency and softens stools but often does not reduce pain or bloating.
Flaxseed fiber and Olive Oil taken orally may increase stool frequency and soften stools in adults and children; topical olive oil massage or enemas have been studied in pediatric severe constipation. Aloe-containing products have laxative history, though oral aloe latex safety concerns limit use. See the heatmap and evidence reviews below.
