Laxatives and vitamin and mineral absorption

Answer:

Some laxatives can interfere with the absorption of particular vitamins or minerals, potentially causing vitamin deficiencies or electrolyte imbalances if taken for prolonged periods of time Short-term and occasional use should not cause an issue. Get the details for specific laxatives, such as mineral oil, magnesium, psyllium, oat bran, fiber, bisocodyl, senna, lactulose, and polyethylene glycol >>

Note: A concern with psyllium supplements is that tests by ConsumerLab found many to have relatively high levels of lead, a toxic heavy metal. See the results in ConsumerLab's Psyllium Fiber Supplements Review, which includes more information about psyllium, its uses, dosage, and safety.
