Is there a legal limit for caffeine content?

The answer to that is it depends on the country. A few examples of laws related to caffeine content for food and drinks include the following:

In the United States there is a limit of 65mg of caffeine per 12 liquid ounce in beverages. This may only be for carbonated beverages. (What we call coke here in the south and my northern friends like to call pop.) There is also a limit of 200mg in pills such as Vivrin. For more info on caffeine contents in drinks check out  High Caffeine Pop from 'Energy Drinks' Revealed. Also check Ask Erowid for more specifics.

Here is the FDA regulation text:

[Code of Federal Regulations]
[Title 21, Volume 3]
[Revised as of April 1, 2003]
From the U.S. Government Printing Office via GPO Access
[CITE: 21CFR182.1180]

[Page 462]




Subpart B--Multiple Purpose GRAS Food Substances

Sec. 182.1180 Caffeine.

(a) Product. Caffeine.
(b) Tolerance. 0.02 percent.
(c) Limitations, restrictions, or explanation. This substance is
generally recognized as safe when used in cola-type beverages in
accordance with good manufacturing practice.

This text is available at the GPO web site. Essentially what this means is that for a drink or food to fall within the FDA's guidelines 68 mgs per 12 oz is acceptable. Some drinks do have more. Most if not all energy drinks are legally classified as supplements. Supplements (vitamins and such) have a much lower oversight than food and drugs. Natural caffeine levels are also exempt from these regulations so coffee based drinks may have more caffeine than the limit without being classified as a supplement.

Australia has a limit of Australia 145mg of caffeine per liter for non-energy drinks which they refer to as "formulated caffeinated beverage" for legal purposes. Formulated caffeinated beverages can contain up to 320 mg/L of caffeine but not less than 145 mg/L of caffeine.

In parts of Northern Thailand it is completely illegal. It was outlawed as a precursor to meth.


Legal Limit

I would like to see where this law on the legal limit of caffeine is written since there are energy drinks which have over 312 mg per liquid oz.

well, it's right there...

above on this page, it says "This text is available at the GPO web site." that's a link, I'd try it. I see what you're saying, though. It's amazingly annoying trying to find what the actual text of a law is, but this site apparently knows what they're doing.

There are no energy drinks

There are no energy drinks that have that much caffeine. Here's a good chart to go by:

312 mg? seriously? 2 ounces

312 mg? seriously? 2 ounces of that and your blood pressure would be through the roof and your heart beating its way out of your chest


He/she is wrong nothing has that much caffeine per liquid ounce, he/she clearly doesn't know how much a liquid ounce is. Im English and there doesn't seem to ever be an energy drink with more than 32mg/100ml. I'm sure there is more in coffee but no way as much as that stated above, I think he is confusing ounce with litre

pure caffeine

pure caffeine is legal to buy in the uk i recently purchased 50g of it and ended up in hospital from a caffeine over dose so if you must buy it use it in moderation ppl pleease


There's caffeine gum that contains 100mg per piece. used for military mainly but you can buy it here: And, it works!
