About Us

Caffeine Informer believes that accurate caffeine information must be freely available to all.
Research shows that caffeine consumed in moderation can have some positive benefits for most people.
However, many others experience negative effects, including withdrawal symptoms, when reducing caffeine intake.
We believe manufacturers must label caffeine amounts accurately, and tighter regulation of caffeine is needed.
Our mission is to inform and educate the consumer about the risks of caffeine and provide a comprehensive and accurate resource of caffeine amounts.

Got a Question?
How accurate are the caffeine amounts?
See how we find caffeine amounts.
Aren’t caffeine amounts supposed to be listed on drinks?
The US FDA requires caffeine to be listed on the ingredients list, but as caffeine is not a “nutrient”, the exact amount does not have to be listed (FDA). That is why we maintain the caffeine database.
Is caffeine safe?
In 1958, the FDA placed caffeine on its GRAS (Generally Recognized As Safe) list. It suggests a dosage of no more than 400mg per day. Most health authorities believe pregnant women should consume no more than 200 mg of caffeine daily.
Are there limits on how much caffeine is allowed in beverages?
The FDA rules are outdated and never anticipated the proliferation of highly caffeinated products currently available. There are no strict limits – unlike other countries, such as New Zealand and Australia, that limit caffeine amounts to 32 mg per 100 ml of drink.
Does this site have a bias in any way?
We aim to present both the pros and cons of caffeine consumption without any implicit bias. To see more about our terms, mission, and background – see our Terms of Use.
Can caffeine really kill you?
Yes, it can. We made the Death by Caffeine calculator as a fun tool to highlight the levels of caffeine in drinks. It is also a serious reminder of the toxicity of caffeine in higher dosages. People have died after overdosing on caffeine pills, and over-consumption of high-caffeinated energy drinks has made headlines over the last few years.
