How much caffeine is dangerous? A recent lawsuit against Panera Bread that implicates the chain’s caffeinated “Charged Lemonade” in the death of a college student with a heart condition may have given some folks renewed jitters about whether their go-to energy drink is still safe to sip.
The student, Sarah Katz, 21, drank Panera’s Charged Lemonade — which contains up to 390 milligrams of caffeine in a 30-ounce serving — in September 2022, according to the lawsuit filed in the Philadelphia Court of Common Pleas. She died later that day, and the suit brought by her parents accuses the chain of failing to warn consumers about its ingredients. The company was not immediately available for comment. But it is now displaying an enhanced disclosure about its Charged Lemonade, a spokesperson told NBC this week. So, is 390 milligrams a lot of caffeine? It’s quite a lot, in fact. Healthy adults should stick to less than 400 milligrams of caffeine a day, according to the FDA. The problem is that many of us are probably sipping more of this stimulant than we realize, maybe even well exceeding this recommended daily limit, which could pose health risks like insomnia, nervousness, restlessness, nausea, increased heart rate and other side effects. But what does 400 milligrams of caffeine actually look like?
The amount of caffeine in your morning coffee depends on the portion size and also the concentration of coffee in your particular brew, so be sure to look up its nutrition content.
