EnXtra Caffeine Amplifier | Efectiv


EFECTIV enXtra® capsules provide the clinical dose (300mg) of the award-winning plant extract ingredient enXtra®.

enXtra® is a caffeine free energy supplement, which has been clinically proven to:

  • Increase baseline alertness scores up to five hours compared to several other plant extracts.
  • Increase focus attention to a greater extent compared to caffeine and placebo.
  • Amplify the effects of caffeine without increasing heart rate or blood pressure.

Usage & Faq

Take 1 capsule 15-30 minutes before exercise, work or study. Can be used in combination with caffeine to provide a complete energy solution for mental energy.


Q: Is enXtra a stimulant?

A: No, enXtra is made from a proprietary extract of Alpinia galanga, a commonly used spice in Asian cooking, and does not have the same affect on the body that a stimulant such a caffeine has.

Q: Can enXtra be used on an evening or will it impact my sleep?

A: enXtra can be used any time of the day, without impacting sleep!

Q: Can I stack enXtra with a pre-workout?

A: Absolutely! enXtra stacks perfectly with both stim and non-stim pre-workouts to enhance energy levels without impacting heartrate or blood pressure.
