Tag: Safe daily caffeine

Over 90% of adults consume caffeine daily, but many are unsure of the safe limit. For most healthy adults, experts cite 400mg of caffeine—or about four 8-ounce cups of black coffee—as the safe daily threshold.

According to the U.S. Food and Drug Administration (FDA), up to 400 milligrams (0.4 grams) of caffeine per day is considered safe for most healthy adults and is not typically associated with dangerous or negative effects. However, this guideline is not universal and can change based on individual health factors.
