We do not recommend taking Zone alongside coffee or other caffeine based stimulants.
Excessive caffeine consumption can lead to jitters and the eventual “caffeine crash” that many will have experienced after a particularly large coffee.
The advantage of Zone over coffee and other caffeine based stimulants is that it contains a number of unique ingredients. These ingredients have been specifically selected in ratios that work synergistically with caffeine, amplifying its positive effects, such as an alert, energetic feeling while also eliminating the negative effects associated with excessive caffeine consumption. Zone provides a smooth, sustained boost, not a jolt and crash.
