☕ How Much Coffee is Too Much?
Short answer: more than 4 cups a day.
More than 400mg of caffeine per day (about 4 regular coffees) is considered too much for most adults.
The FDA and most health bodies agree: up to 400mg of caffeine per day is safe for healthy adults. That's roughly 4 standard cups of brewed coffee, or about 6 cups of tea.
Signs you've had too much: jitters, anxiety, heart palpitations, trouble sleeping, and that specific regret that hits at 4pm when you realise your third espresso was a mistake.
Pregnant women should limit to 200mg/day. Teenagers should aim for under 100mg. And if you're adding caffeine to caffeine (coffee + energy drink), you're playing a dangerous game with your nervous system.
