Does Chocolate have caffeine?

[aparenz]

I've been looking around the interwebs and there is a rather extensive debate with some sources saying chocolate only contains theobromine, others saying it contains both. Can anyone clear this up with certainty?

Theobroma cacao seeds contain 0.1-0.4% (max. 1.7% ) caffeine. Ref: "Biogenic Pharmaceuticals" by Teuscher, Melzig & Lindequist, 6th edition, WVG Stuttgart 2004.

If chocolate contains caffeine, too, depends on the manufacturing process, but it is very likely. Nonetheless is theobromine the dominating alkaloid.

Theobromine is pretty similar to Caffeine effects wise though. I believe they act in similar areas.

It'll keep you wired for days. I like to take it pre-workouts.

Isn't theobromine (as well as theophylline) a metabolite of caffeine?

"The caffeine in chocolate varies according to the type of chocolate one chooses. Caffeine in chocolate that is unsweetened or is semi-sweet usually contains about five to 10 milligrams of caffeine per ounce of chocolate. Caffeine in chocolate with milk added is usually measured at five milligrams or less per ounce. ... Generally, caffeine in chocolate is present in higher amounts, as the chocolate gets darker".
