L-Theanine and caffeine: the ratio question

The classic pairing, why the research keeps landing near 2:1, and why we deliberately split the two across different jars.

the short answer

L-Theanine is the green-tea amino acid known for smoothing caffeine’s edges — supporting calm, settled attention without sedation.† Studies pairing the two often use roughly twice as much theanine as caffeine. moodebles splits them on purpose: caffeine lives in Hiking Energy, theanine in the Clarity jars — so you control the ratio.

why this pairing is everywhere

Caffeine gives you the lift; it also gives some people the static — the jitter, the too-fast edge. L-Theanine, an amino acid from green tea, is the classic counterweight: it supports a calm, even kind of attention, which is exactly what you want caffeine to feel like.†

Research on the combination frequently lands near a 2:1 ratio — around twice the theanine to the caffeine. Green tea itself ships both, which is why “tea focus” and “coffee focus” feel different.

why we split them

Bundling caffeine and theanine into one gummy locks you into someone else’s ratio at someone else’s hour. We’d rather hand you the components:

  • Hiking Energy: 75 mg caffeine, no theanine — the clean lift.
  • Mental Clarity: 200 mg theanine, no caffeine — the smoothing pass, plus the full focus stack.
  • Clarity Daily: 100 mg theanine — the everyday version.

Take Clarity with your morning coffee and you’re near the studied ratio. Take it alone and it’s a caffeine-free focus stack. Take Hiking Energy with Clarity before a big climb-and-work day and you’ve built the 2:1-ish combination yourself — roughly 200 mg theanine to 75 mg caffeine. Your day, your dials.
