The 10 Most Caffeinated Diet Drinks
If you are moderating your caffeine intake - it's worth noting that most diet soft drinks have as much (or sometimes even more) caffeine than their sugar-filled counterparts.
Diet Coke in particular has 30% more caffeine than regular Coca-cola.
Here is a list of the most caffeinated diet soft drinks.

Diet Pepsi Max
Per 12oz can : 69mg caffeine
A can of regular Pepsi-cola contains 38mg caffeine.

Diet Sundrop
Per 12oz can: 69mg caffeine
Sun Drop is a brand of citrus soda drink from Cadbury-Schweppes. The level of caffeine in the Diet version came as a complete surprise - but then - even the regular version has 63mg in a 12oz can. Note: regular can displayed.

Diet Mountain Dew
Per 12oz can: 55mg caffeine
Mountain Dew is one of the most popular citrus soft drinks. Both diet and regular have the same amount of caffeine. In countries outside the USA - Mountain Dew has either reduced amounts of caffeine (or no caffeine at all).

Pepsi ONE
Per 12oz can: 54mg caffeine
Pepsi ONE is a very similar formulation to Diet Coke with Splenda - although Pepsi ONE contains significantly more caffeine.

Diet Cheerwine
Per 12oz can: 48.1mg caffeine

Diet RC Cola
Per 12oz can: 47.3mg caffeine
Royal Crown (RC) colas have been around for a long time and are currently owned by Cadbury Schweppes. As in the case of Diet Coke - here the diet version has more caffeine than the regular RC Cola. 2

TaB
Per 12oz can: 46.5mg caffeine
TaB (from Coca-cola) is one of the oldest diet or sugar-free soft drinks around. It has more caffeine than Diet Coke

Diet Coke
Per 12oz can: 46.5mg caffeine
Diet Coke has significantly more caffeine in it than regular coke (34.5mg).

Diet Sunkist Orange Soda
Per 12oz can: 41.5mg caffeine
Contains slightly more than the regular version of Sunkist. Who would have thought that Orange Soda was caffeinated?

Diet Dr Pepper
Per 12oz can: 41mg caffeine
Contains the same amount as regular Dr Pepper.
Reference - Instant coffee

What about Diet Coke Plus?
The new vitamin-filled Diet Coke Plus does not (yet) list caffeine, nor is it listed on the Coca-cola nutrition site, and the response to my email to coca-cola only told me that the drink contains "vitamins and minerals" - and neglected to list the caffeine amount!
Diet Pepsi?
Didn't even make it to this list. Diet Pepsi has 36mg caffeine in a 12oz can.
Sources: The Energy Fiend caffeine database and caffeine in citrus, along with PepsiCo, Coca-cola, Sundrop.
How could you leave out Vault Zero? At 70.5mg per 12oz. can, it ranks higher than any of the others listed. (And is my current favorite, btw.)
ReplyNo one has mentioned my favorite (spelled favourite here in Australia) -- no caffeine Diet Coke. If it is not on the shelf when I'm shopping I MIGHT buy the other lo-cal Coca-Cola and Pepsi drinks, but usually I pass them up and wait for the no caffeine Diet Coke at the next store or on my next shopping trip. Most of the previous comments seem to be from the USA (where I was born and lived the first twenty-one years of my life) or Canada. Here in Australia, the no caffeine Diet Coke is readily available. Is it a line that is not sold in the USA/Canada?
Side note / comment about caffeine. In 1993 my husband and I made a three-month trip to the USA. At one stage I needed a pain killer and went to various pharmacies (known here as chemists or chemist shops) looking for what I had been taking here -- paracetamol. The major brand for it here is Panadol, but I buy it as a cheaper generic house brand from the major supermarkets.
After unsuccessfully scouring the shelves of several pharmacies in Minneapolis, where we happened to be at the time, reading the active ingredients on all kinds of pain killers and getting nowhere, I asked the pharmacist if it was available in the US or was not on the shelf because it was by prescription only. Paracetamol meant nothing to him, but he checked it for me and found it was sold in the US as acetaminophen. I bought some and took them according to the package instructions, as I did with paracetamol in Australia.
Later that day while we were visiting one of my high school teachers and his wife I found myself "charged up" or acting rather "hyper." As I had not seen these people for over twenty years, I put my feelings down to excitement which I also figured was the reason I spent hours trying to get to sleep that night.
The next day I discovered that the painkillers contained caffeine. At that stage I drank one or two cups of tea a day and had a cup of coffee once or twice a year. Perhaps those who have caffeine in one form or another would not have reacted to the painkillers as I did, but once I stopped taking them I was able to calm down again.
Panadol and the generic brands of paracetamol here do not contain anything else (at least the ones I buy don't).
While writing this I could not remember what paracetamol is known as in the US. Googling "paracetamol" + "name in USA" gave me several results including this one - http://www.irishhealth.ie/askdoc.html?q=5703§ion=1 (watch the wraparound, depending on how this prints online) - which provided it for me.
Have I started a new thread -- caffeine in medications?

ReplyThere are caffeine-free "no caffeine" carbonated drinks for just about every large name brand soda (Pepsi, Diet Pepsi, Coke, Diet Coke, Dr. Pepper, etc.). As far as caffeinated medication, yes, some OTC medications do contain caffeine, such as Excedrin, but this is not plain Acetaminophen (Brand name Tylenol). After ingesting caffeine, it is completely absorbed within 30 to 45 minutes, and its effects substantially diminish within about three hours. It is eventually excreted so there is no accumulation in the body. Caffeine has been shown to affect mood, stamina, the cerebral vascular system, and gastric and colonic activity (www.medicinenet.com) Caffeine is actually used in certain instances for medical treatments, such as with alcoholics who receive "banana bags" which contain multivitamins and other additives, one of which is caffeine. There is also a study showing Caffeinol, a drug combination of a huge does of caffeine and alcohol are helpful with stroke patients. Caffeine is good, but as we all should know, you can have too much of a good thing.
ReplySTOP DRINKING ANYTHING WITH ASPARTAME OR YOU WILL DIE....
ReplyWE ARE ALL GOING TO DIE SOMEDAY....Please....GET REAL
ReplyWhen I lived in the midwest (Nebraska), I could be caffeine-free diet Mountain Dew. Have they stopped making it in the US? I know it's not available on the west coast, but just assumed it was still on the shelves back home.
ReplyKaren--yeah, I live in Wisconsin and we can get caffeine-free Mountain Dew. But then, what's the point? LOL. I only drink Diet Dew when I need a quick burst of caffeine.
Replyi love the new diet pepsi max (thanks for the review)...it gives me that extra punch i need by the end of the work day...and their commercials crack me up!! i was on their website watching the ads the other day and pass them around the office...makes me yawn everrrry time =)
ReplyI'm coming a little late to the game, but I'll mention my favorite: Diet Manhattan Special.
ReplyCaffeine is also a big issue for those with heartburn problems. The caffeine relaxes the Lower Esophageal Sphincter (LES) which allows stomach acid to wash back into the esophagus. Over time this causes permanent damage, not to mention the pain.
ReplyYou can order Cheerwine off their website. A bit pricey but if you've grown up on the stuff, then moved away (like I did), and want to get it, they'll ship 2 12-packs ($12 plus shipping) to your door.
ReplySo we should basically keep on drinking what we love? You know... I never ever thought this would happen but I feel enlightened. I think this is such a phenomenon. Thank you so much and happy trick or treating. [I'm giving out soda's this year.] Yeay! [:
ReplyI could never tolerate the taste of diet sodas...until the day I tried diet Pepsi MAX...I really do enjoy this soda and can even drink them warm...thanks to Pepsi for this great soda.

ReplyI can't believe the caffeine in the diet sunkist orange drink. Also I am pretty surprised diet pepsi isnt on the list as well!
ReplyI have been drinking Diet Sunkist for several years now and just learned that it does have caffeine! I was told by my doctor not to have any caffeine boy was I wrong when I started drinking Diet Sunkist.
ReplyI only drink one a day so I think I will just keep on drinking.............

ReplyOK does anyone know what conclusion means????
Replynever mind
ReplyA note on the Canadian regulations:
I was doing some research into the Mountain Dew in Canada (where I live) as someone told me the cola only caffeine was not true anymore and I was not able to provide a good reason why it would still be in place. My recent findings, as described by Health Canada, are that caffeine is allowed to be added to a food product, which soda beverages are classified, unless it is a cola-type beverage. All other products with added caffeine are listed as health products which are not regulated as food which is where the energy drinks made their inroads to Canada.
The other interesting tidbit I learned was that Canada is one of the only nations in the world to regulate caffeine as a food additive. I am supposing the amount of caffeine in coffee, tea and chocolate and the associated consumption has led to a general belief that caffeine is safe in any quantity but here that belief is not held (which I think may actually be somewhat smart in that too much of anything is not usually good.) This lack of regulation may also have changed recently based on some of the other articles/postings I have seen regarding the European Union and United States.
ReplyApparently I should proof read better or drink less Red Bull:
My recent findings, as described by Health Canada, are that caffeine is allowed to be added to a food product
should read:
My recent findings, as described by Health Canada, are that caffeine is _not_ allowed to be added to a food product
