This site uses two specifically different phrases at two different timeline stages — worth reading "calmer focus" and "recall sharpens" as distinct claims, not interchangeable ones.
"Calmer" describes a felt, subjective quality tied to L-Theanine's mechanism, while "sharpens" describes a more specific, outcome-focused claim tied to Bacopa and Ginkgo's memory mechanisms — worth reading each claim against its specific ingredient basis.
If you're specifically watching for memory improvement, "calmer focus" in weeks 1-2 isn't the signal to judge that by — worth waiting for the month-2 "recall sharpens" stage before evaluating memory-specific claims.
