Tag: 450mg caffeine

According to the U.S. Food and Drug Administration (FDA), up to 400 mg of caffeine is considered a safe daily amount for most healthy adults. However, a 450 mg dose—exceeding that guideline—can trigger a range of significant physiological and psychological effects, from heightened alertness to adverse side effects.

The FDA suggests a 400 mg daily limit for healthy adults, the equivalent of about four cups of coffee. Consuming more, such as 450 mg of caffeine, pushes beyond this recommended threshold and can trigger a range of noticeable side effects, from anxiety to a rapid heart rate.
