Why this formula

Caffeine alone sharpens attention but raises heart rate and induces jitter. L-theanine alone calms but doesn't energize. Combined at a 2:1 ratio, they produce the focus-without-anxiety state that has been the subject of fifteen separate clinical trials. We use Suntheanine®, the only L-theanine with a clean safety profile and clinical data.
