FDA Advises on Caffeine Intake

Up to 400 Milligrams Per Day Considered Safe for Most Adults

Latest USDA Findings

The Food and Drug Administration (FDA) has advised that up to 400 milligrams (mg) of caffeine per day appears to be safe for most healthy adults. This guidance is based on the latest research, which suggests that moderate caffeine consumption does not pose significant health risks for the general population.

The USDA's most recent Dietary Guidelines for Americans recommend that adults limit their caffeine intake to less than 400 mg per day. However, the FDA notes that there is some variability in individual caffeine tolerance, and some people may experience adverse effects from consuming less than 400 mg per day.

Caffeine is a stimulant that can increase heart rate, blood pressure, and wakefulness. It is found in coffee, tea, energy drinks, and chocolate. While moderate caffeine consumption is generally safe, excessive caffeine intake can lead to anxiety, insomnia, and other health problems.

The FDA advises that pregnant women and individuals with certain health conditions should consult with their healthcare provider for personalized guidance on caffeine intake.
