How accurate are the Caffeine Amounts?
We’ve sourced the amounts from the manufacturer or by examining the nutrition label. Sometimes independent lab tests show caffeine levels to be slightly different from that which manufacturers claim. To see how we sourced an item, click on its link and go to the bottom of the page (for journal citations go here
)If you believe any of these amounts are incorrect please contact us
so we can rectify.
Is this per Serving or per Bottle/Can?
The caffeine amounts are for the whole container. Do you know anyone who drinks half a coffee, then leaves it for the next day? Neither do we. We typically drink EVERYTHING in a can or bottle in one sitting, so there’s no point at looking at caffeine per serving.
I Can’t Find a Drink
Drinks that don’t contain caffeine are not listed. Neither do we list alcoholic drinks mixed with caffeine. Drinks that no longer seem to be on the market are listed on the drink graveyard
– along with some drinks where we could not find out the caffeine levels.
