How Much Caffeine Is Too Much?
You love the buzz—but how much is too much?
Caffeine is the world’s most widely used stimulant, and it's in nearly everything from energy drinks to pre-workout powders to that “just-one-more” coffee. But when does a good thing turn into a jittery, sleepless mess?
Let’s break it down.
Caffeine works by blocking adenosine, a neurotransmitter that tells your brain it’s tired. With that out of the way, dopamine and adrenaline kick in—giving you focus, energy, and motivation. But overdo it, and your body pushes back hard.
According to the FDA, 400mg of caffeine per day is considered safe for most healthy adults. That’s about:
- 4-5 cups of coffee
- 2-3 energy drinks
- One massive scoop of your favorite pre-workout
Go beyond that, and you might start to feel:
- Rapid heart rate
- Anxiety or restlessness
- Insomnia
- Digestive issues
- Dependency and withdrawal headaches
