Vivarin Smooth Energy® is a unique bi-layered caffeine tablet designed to deliver smooth, sustained energy. Unlike standard caffeine tablets that release all their caffeine at once—often leading to a quick spike followed by a crash—Vivarin Smooth Energy® is formulated to work differently.
One layer provides fast-acting caffeine for an immediate boost, while the second layer releases gradually to help maintain alertness and energy over time. Use only as directed.
