Alpha-GPC
A multicenter RCT in mild-to-moderate Alzheimer's dementia (De Jesus Moreno, 2003, n=261) found 1200mg/day improved ADAS-Cog, MMSE and global scores versus placebo at 90 and 180 days, and a 2023 meta-analysis supports benefit in cerebrovascular cognitive impairment. In healthy men, a single 315–630mg dose improved Stroop performance but not N-Back or Flanker (Kerksick 2024). Sports trials are inconsistent: a lower-body force gain after 6 days at 600mg (Bellar 2015), no strength effect at 250–500mg for 7 days, and no power-output effect after a single 630mg dose.

Mecanismo de acción
Alpha-GPC (alpha-glycerylphosphorylcholine) is the most bioavailable choline precursor. It delivers choline directly across the blood-brain barrier, where it is used to synthesise acetylcholine. It also supports cell membrane phospholipid synthesis. It is often marketed for growth hormone release, but a 2024 RCT at 630mg found no growth hormone difference versus placebo.

Recomendaciones de combinación
Ingredientes que se combinan bien con Alpha-GPC y por qué.
Alpha-GPC provides immediate acetylcholine support; Lion's Mane drives long-term NGF synthesis. Neither overlaps mechanistically — a clean acute + long-term pairing.
Alpha-GPC handles acute memory encoding via acetylcholine; Bacopa handles memory consolidation and storage. Together they cover both encoding and consolidation stages of memory formation.
Huperzine A prevents acetylcholine breakdown while Alpha-GPC increases acetylcholine synthesis. Powerful combination in theory — but use with caution and low doses, as cholinergic overload (nausea, headache, muscle cramps) is a real risk. Not recommended without experience.
Preguntas frecuentes
Alpha-GPC vs Citicoline — which is better for focus?
Both are excellent. Alpha-GPC has a slight edge for acute cholinergic effects and is preferred for workout performance. Citicoline also provides cytidine (uridine precursor), giving it a broader neuroprotective profile. For pure focus and acetylcholine, Alpha-GPC wins slightly; for comprehensive brain health support, Citicoline is more complete. Don't stack them together — you'll get too much choline activity.
Is it safe to combine Alpha-GPC with Huperzine A?
Use caution. Both increase acetylcholine (Alpha-GPC via synthesis, Huperzine A via inhibiting breakdown). The combination is potent and can cause cholinergic overstimulation — symptoms include nausea, headache, excessive salivation, and muscle cramps. If combining, use lower doses of each (e.g. 200mg Alpha-GPC + 50mcg Huperzine A) and do not take daily.
Why does Alpha-GPC powder go sticky?
Alpha-GPC is highly hygroscopic — it absorbs water from the air quickly. This is normal and doesn't affect potency. Store in an airtight container in a cool, dry place. Capsule form avoids this problem entirely.
Is there a cardiovascular risk with Alpha-GPC?
Unresolved. The CARDIA cohort study (published 2024) linked higher plasma choline — not alpha-GPC supplements — with incident cardiovascular disease, while a meta-analysis of dietary choline intake found no association. No study has tested alpha-GPC supplementation directly for cardiovascular outcomes. If you have cardiovascular disease, discuss it with your doctor.
