PerformZen is designed to be fast-acting, so a serving of PerformZen (2 capsules) works most efficiently when taken 2-3 hours prior to work or a high-stress/high-anxiety performance of any kind.
For longer performances and situations, to maintain calm, focus & creativity you can take an additional capsule 1-2 hours in to the actual event, extending the ‘effectiveness window’ of PerformZen and it’s calming, focusing and confidence-boosting effects.
