About this product

NOW Foods Magnesium Oxide Powder is a dietary supplement formulated to provide short-term relief from constipation and heartburn. It works by drawing water into the intestines to promote bowel movements and neutralizing excess stomach acid. While it contains a high amount of elemental magnesium, its absorption rate is low, making it less effective for long-term health benefits. The product is manufactured in the USA and supports basic magnesium levels for essential body functions.
