Caffeine is a natural stimulant well-known for itshealth benefits, from boosting your mood to reducing your risk of type 2 diabetes. However, having too much can be harmful to your body.Everyone widely consumes caffeine, whether it’s in coffee, tea or energy drinks. According to theNational Health and Nutrition Examination Survey, approximately 90% of the U.S. population relies on caffeine’s stimulant effect to get them moving physically and mentally each morning. This isn’t necessarily a “bad” or unhealthy habit, assuming those caffeinated beverages aren’t loaded with added sugars. In fact, research suggests that moderate caffeine consumption improves alertness, cognitive performance and mood and evenhelps you live longer.
But at what point does caffeine intake can be unhealthy? What are the signs and symptoms of too much caffeine? And how much is too much in a day?
How Much Caffeine Is Safe
In general, the2020-2025 Dietary Guidelines for Americansadvise that up to 400 milligrams of caffeine—around four to five cups of coffee—each day can be part of a healthy diet. TheFDAalso cited this dosage as causing no adverse effects in most adults.
However, some people could be more sensitive to caffeine’s stimulant effects. If you take certain medications, such as antidepressants and anticoagulants, you should talk to your health care team to learn how much caffeine is safe for you. Also, people who are pregnant, breastfeeding or becoming pregnant should consume no more than 200 milligrams of caffeine per day, per theNational Institutes of Health.
There are no U.S. official guidelines on how much caffeine is safe for kids and teenagers. Yet, according to theGovernment of Canada, children and teenagers should not consume more than 2.5 milligrams per kg of their body weight.
