Cholinergic
In one line: The chemical your brain uses to form memories and your nerves use to fire muscles.
Picture this: Acetylcholine is the "recording" chemical — it's central to laying down memories and paying attention, and it's also the signal your nerves send to make a muscle contract. Run low and you get brain fog and a weaker mind-muscle connection; top it up and both sharpen.
Step by step:
- The raw material choline (from eggs, or supplements) is turned into acetylcholine.
- Acetylcholine crosses the gap between nerve cells (or between nerve and muscle) and passes the signal.
- An enzyme then breaks it down to end the signal.
- You can raise it by supplying more choline, or by blocking that breakdown enzyme.
Why it matters for you: Alpha-GPC and citicoline supply choline for sharper memory and focus (and a small pre-workout mind-muscle boost). Huperzine A blocks the breakdown enzyme, keeping levels higher.
Turn it up: alpha-GPC, citicoline, huperzine A, nicotine (which directly hits acetylcholine receptors). Don't be fooled: more isn't always better — too much acetylcholine causes headaches and tension.
