NOW Foods L-Theanine uses Suntheanine, the patented, pure L-isomer form developed by Japan's Taiyo International and used in nearly all published L-theanine research. Unlike cheaper racemic D/L mixes, Suntheanine delivers only the bioactive L-form, ensuring the calming alpha-wave response the clinical studies validate. Take 1 capsule any time of day; it pairs especially well with coffee or matcha to smooth the stimulant edge without sacrificing alertness. The 120-capsule bottle at 200 mg each provides 4 months of daily use.
Promotes alpha brain waves, calm, focused energy without sedation. Pairs beautifully with coffee.
