Vivarin contains only one active ingredient: caffeine. No sugar. No wacky herbs. No added energy boosters.
Instead of having to drink a lot of sugar and other additives to get the mental focus you need, you can just take one Vivarin tablet for 200 mg of caffeine, which is about the same as a cup of coffee.

Vivarin works quickly to bring you all of the benefits of caffeine – more alertness, wakefulness and hours of energy. Since it’s small, you can take it with you anywhere – from the construction site to the amphitheater.
Get the benefits of caffeine when you need them – and where – with Vivarin.
