enXtra® - The plant with performance pedigree – Hoola

enXtra® - The plant with performance pedigree

Here's why we chose enXtra® (Alpinia Galanga) + Caffeine for Hoola : a clean, steady energy bump that helps you stay switched on - without the jitters or the mid afternoon crash.

Alpinia galanga is a spice cousin of the ginger family that's been used traditionally for vitality and clarity. Modern research zooms in on a standardised extract known as enXtra® and the results are genuinely exciting for busy brains with full calendars.

In a randomised, double blind, placebo controlled cross over study, researchers gave healthy adults either Alpinia Galanga extract, caffeine, both together, or placebo, and tested mental alertness and sustained attention over five hours. The Alpinia Galanga extract improved alertness at 1, 3 and 5 hours, and importantly, when combined with caffeine it improved sustained attention and impeded the caffeine crash around the 3 hour mark as outlined in the study.

Fast lift, steady focus - For hours!

If your the type who wants your brain to click into gear quickly and stay there, enXtra® shines bright. A single 300mg dose (the exact amount in Hoola) has been shown to deliver a rapid increase in mental alertness that lasts up to 5 hours, in a randomised, double blind, placebo controlled crossover trial of 62 people. Participants also improved on reaction time and correct responses, with fewer errors on cognitive tests versus placebo.

Caffeine's perfect co-pilot

Caffeine is brilliant for wakefulness, but you know the script, a quick buzz then...fizzle. The enXtra® + Caffeine combo aims to smooth that curve. In the head to head study, pairing Alpinia Galanga with caffeine helped maintain attention and blunt the dip seen as caffeine wears off. 

And because we care about how you feel on Hoola, not just how you perform, its good no know long term safety has been investigated too. Over 12 weeks, enXtra - with and without caffeine, showed no significant changes in heart rate or blood pressure. Participants also reported higher alertness and calmness vs. placebo, while sleep quality stayed steady.

What this means for your day with Hoola

  • Clearer mornings: enXtra® helps your brain "switch on" quickly, so the first few hours of the day feel crisp and purposeful, not groggy.
  • Smoother energy: our thoughtful pairing of enXtra® with natural caffeine is designed for focus that holds, no cliffs.
  • Stay accurate under pressure: studies report improvements in reaction time and correct responses, handy for deep work, workouts, and everything in between.
  • Daily ritual friendly: research over 12 weeks found no meaningful changes in common cardiovascular markers and no disruption to sleep quality. That matters when you are trying to build a habit.

How we dose the difference

We've built Hoola so its experience matches your ambition: reliable, repeatable, and enjoyable. the clinical literature commonly evaluates enXtra® at 300 mg for acute effects and across multi week use for safety and mood markers. We've considered that evidence alongside our broader formula with nootropcis, adaptogens, vitamins and minerals, to support mental performance, a healthy stress response, and everyday brightness.

The Hoola take

think of enXtra® as a focus stabiliser. Caffeine helps you hit "go", enXtra® helps you keep cruising, so you can stay present for the work, the workout, and the wins. It's one of those small, smart choices that stacks up, scoop by scoop.
