Lab notes 001: Green tea's nutraceuticals
Caffeine usually raises alertness, but on its own it can overshoot into jitters, anxiety, or sleep disruption in sensitive people. Pairing it with l-theanine can deliver a calmer, more controllable focus instead of raw stimulation. EGCG is a different lever, discussed mainly as a long term neuroprotective ingredient. Overall, green tea's benefits are likely to stem from its combination of compounds, not just a single isolated ingredient. More research is needed on the synergistic effects of these substances on cognition.
