Does Rejuveniix have the same effect as an energy drink?

No.

Unlike other energy drinks and supplements, Rejuveniix does not have a "crash" period after it begins to wear off. These unique ingredients are specially combined to increase energy without causing a crash or letdown hours later, by working with your body to increase energy naturally.*
