                                The U.S. Food and Drug Administration (FDA) cites 400 milligrams a day as the safe daily intake for most healthy adults, meaning 1100 mg is nearly triple the recommended limit. Consuming such an extreme amount poses significant health risks and is considered a dangerously high dosage that can lead to severe and even toxic effects.
