BioLift can still offer benefits if you experience loss of alertness and poor concentration from lack of sleep. However, BioLift is not a substitute for sleep. Your sleep cycle is an important part of your circadian cycle and a time of recovery for the body. We designed BioLift to work in harmony with your circadian rhythm. If after drinking two BioLifts, the effects fade faster than usual, the best way to revitalize yourself is through sleep. We recommend that you get plenty of rest and proper sleep, especially if you are exhausted.
