How much caffeine is safe?
Health authorities suggest up to 400 mg of caffeine per day is safe for most healthy adults — roughly four cups of brewed coffee. Pregnant women are usually advised to stay under 200 mg.
Signs you’ve had too much
Jitteriness, a racing heart, anxiety, an upset stomach and trouble sleeping can all signal too much caffeine. Caffeine can stay in your system for hours, so afternoon coffee can affect sleep.
