L-Theanine and Caffeine Stack
An L-theanine and caffeine stack combines theanine with caffeine to reduce jitters while keeping alertness—often a 2:1 theanine-to-caffeine ratio in small studies.
An L-theanine and caffeine stack pairs roughly one hundred to two hundred milligrams L-theanine with moderate caffeine—often a two-to-one theanine-to-caffeine ratio—to smooth jitters while preserving alertness in small trials. Green tea offers both naturally.
Avoid stacking late day.
