Most choline supplements never make it past the gut. Alpha-GPC does. It crosses the blood-brain barrier intact and is rapidly converted into acetylcholine — the neurotransmitter behind focus, memory, and learning. At 300mg, it is the dose used in the research showing reliable improvements in mental energy and reaction time.
Take one capsule with breakfast or before deep work. Pair with caffeine for cleaner focus, or with L-Tyrosine for stress resilience. Effects are typically noticeable within 30 minutes.
