The definition of caffeine, pros, cons, and how much one should safely consume.
You’re probably most familiar with caffeine from the java jolt you get from your coffee. It’s best described as a bitter substance that’s present in more than 60 plants, according to the U.S. National Library of Medicine. But that’s just the official definition. For so many people, caffeine is what wakes them up and gets them going in the morning. Indeed, it’s a psychoactive stimulant that acts on your central nervous system to drive your energy up.
While you may pour yourself endless cups of coffee to survive the morning, the Mayo Clinic notes that drinking 400 milligrams (mg) of caffeine a day is safe for healthy adults. They note that this is the equivalent to four cups of coffee per day, but that all depends on where your coffee comes from. For instance:
- Standard brewed 8-ounce (oz) cup of coffee: 95 mg caffeine
- Standard instant 8-oz cup of coffee: 62 mg caffeine
- Starbucks blonde roast, 8 oz (short): 180 mg caffeine
- Starbucks blonde roast, 16 oz (grande): 360 mg caffeine
- Starbucks iced coffee, 16 oz (grande): 190 mg caffeine
- Coffee brewed from Keurig, 8-oz cup: between 75 and 150 mg caffeine, depending in part on roasting strength
As you can see, to stay within the safe limit, you should investigate just how much caffeine your specific brew contains. And, if you’re looking to cut down on caffeine, the first step is to reduce your coffee intake, as it’s the most widely consumed source of caffeine, research shows.
