Matcha vs Coffee
| Feature | Matcha | Coffee |
| Caffeine | ~40–180 mg per cup (depends on grade and grams used; ~20–45 mg caffeine per gram). Source | ~70–150 mg per 8 oz (typical brewed cup) (commonly cited ~95 mg average; varies by brew). Source |

Primary Supporting Molecule |
L-theanine (an amino acid) that occurs naturally in tea leaves; when combined with caffeine it tends to promote calm, focused attention vs jittery stimulation. Source | No L-theanine in meaningful amounts; caffeine acts alone, producing faster alertness and (for some) more jitteriness or a sharper “crash.” Source |
| Antioxidants / polyphenols | High in catechins (notably EGCG) and polyphenols — matcha (leaf ground and consumed whole) concentrates antioxidants relative to steeped tea; several reviews find matcha rich in antioxidant compounds. Source | Contains antioxidants and bioactives too (chlorogenic acids, etc.) and is linked to health benefits in many studies — but its antioxidant profile is chemically different from tea catechins.

| Energy Release & Longevity | Smoother onset, sustained focus — caffeine + L-theanine often gives steady alertness with reduced jitter and fewer “crashes” for many people. (Supported by randomized studies of L-theanine + caffeine.) Source | A quicker spike in alertness — quick wakefulness but can produce jitter/rapid energy swings in sensitive people. Source |
