Combinations to know
How these supplements pair with each other and beyond.
Alpha-GPC + Caffeine
Commonly paired pre-workout and in focus stacks; alpha-GPC supports power output and acetylcholine while caffeine adds stimulation.
Caffeine + Taurine
Taurine is a staple of energy drinks alongside caffeine, where it is thought to smooth the stimulant's edge and support cardiac function.
Caffeine + L-Theanine
The classic nootropic stack: L-theanine smooths caffeine's jitters while preserving the focus boost.
Alpha-GPC + Citicoline
Both are bioavailable choline sources that raise acetylcholine; alpha-GPC delivers more choline by weight while citicoline also provides cytidine for membrane synthesis.
Alpha-GPC + Huperzine A
A classic cholinergic stack: alpha-GPC supplies the choline to build acetylcholine while huperzine A slows its breakdown.
Caffeine + L-Tyrosine
Tyrosine and caffeine are commonly stacked for sustained focus; tyrosine may offset the catecholamine depletion that follows caffeine's stimulant effect.
