                                Intravenous (IV) administration of magnesium can take effect immediately in the bloodstream, while oral absorption can begin within an hour but takes longer to raise systemic levels. The speed at which 2g of magnesium is utilized by the body varies significantly based on its delivery method, the specific magnesium compound used, and an individual's health needs.
