Caffeine is a mild stimulant that sparks the body's natural "fight or flight" response. Caffeine causes the adrenal gland to secrete fluid, which is why you feel a sudden rush after drinking a cup of coffee. The Canadian company, Tim Hortons, produces a variety of coffee selections and sizes, each with a different caffeine content.
Tim Hortons' regular brewed coffee comes in four sizes, from small to extra large. A small cup of Tim Hortons' regular coffee contains 80 mg of caffeine, while the extra large size contains 200 mg. The medium and large sizes contain 100 and 140 mg, respectively. Too much caffeine in the diet can cause dehydration and may be difficult on the kidneys, but 1 to 2 cups a day is not considered harmful.
Tim Hortons also provides decaffeinated coffee. Despite its name, however, most decaffeinated coffee contains a small dose of caffeine. A small cup of Tim Hortons' decaffeinated coffee contains 5 mg caffeine, while an extra large cup contains 12 mg. Medium and large cups contain 6 and 9 mg of caffeine, respectively.
Hot Specialty Coffee
Tim Hortons' hot specialty coffee drinks include cappuccinos and mochas. Tim Hortons also offers hot chocolate, which contains a trace of caffeine. The caffeine content in Tim Hortons' cappuccino drinks ranges from 45 mg in the small cup to 110 mg in the extra large; mochas have 50 mg in a small and 130 mg in the large. Tim Hortons' hot chocolate contains 12 mg caffeine in a small cup and 30 mg in a large.
Cold Specialty Coffee
Tim Hortons offers iced cappuccinos as well, which come in regular or supreme varieties. Iced cappuccinos contain a bit more caffeine than the hot version, with 90 mg in the small cup and 150 mg in the large. A medium iced cappuccino contains 120 mg caffeine. Both the regular and supreme iced cappuccinos contain the same amount of caffeine.
