What does Zen Caffeine do?

Caffeine is the world’s most popular performance enhancer. But if you depend on your morning coffee to kick your brain into gear, you’re probably no stranger to the dreaded caffeine crash!

Jitters, anxiety and energy slumps are common side effects of caffeine. We put up with them because, let’s face it, caffeine gets the job done! But what if we could enjoy the energy-boosting, laser-focusing power of caffeine without the side effects?

Zen Caffeine gives you the best of both worlds. It combines 100mg of caffeine – the equivalent of a strong coffee – with 200mg of L-theanine, a natural amino acid.

Human studies have shown that L-theanine relaxes your mind, promotes alertness, and reduces stress and anxiety. [1][2][3] When taken with caffeine at the optimum 2:1 ratio, it’s been shown to improve cognitive performance, while moderating caffeine’s less-desirable side effects. [4][5][6][7]

With Zen Caffeine, you can enjoy:

  • Improved focus, even on demanding tasks.
  • Sustained attention and alertness.
  • The ability to tune out distractions.
  • A feeling of relaxation and wellbeing.
  • Increased energy without jitteriness.
  • Improved memory.
  • Faster information processing.
  • The ability to multi-task without losing focus.

Perfect as a productivity booster, study aid, or pre-workout performance enhancer, Zen Caffeine is you at your post-coffee best – focused, energised and unstoppable!
