Caffeine and Your Health

Caffeine is a natural stimulant found in coffee, tea, and cacao plants. It works by stimulating the brain and central nervous system, helping you stay alert and prevent the onset of tiredness.

• Safe Limits: For most healthy adults, up to 400 milligrams (mg) of caffeine a day appears to be safe. That's roughly the amount of caffeine in four cups of brewed coffee.
• Individual Sensitivity: Some people are more sensitive to caffeine than others, experiencing jitters or sleep disruption even with small amounts.
• Hidden Sources: Be aware of caffeine in soft drinks, energy drinks, and some over-the-counter medications.
