Researched for: acetylcholine and phospholipid metabolism
Also known as: Choline bitartrate, Choline chloride
Choline is an essential nutrient used in phosphatidylcholine and acetylcholine synthesis. The U.S. adequate intake is 425 mg/day for adult women and 550 mg/day for adult men from all sources; the adult tolerable upper intake level is 3500 mg/day. Choline bitartrate and chloride are common supplemental salts and should not be treated as equivalent to citicoline or alpha-GPC on a milligram-for-milligram basis.

Context: NIH Office of Dietary Supplements adequate intake
Formulation: Oral-mucosal formulations are not dose-equivalent to injectable or topical formulations.
Route safety: Use only in the cited label or guideline context; route, formulation, indication, and patient-specific limits still apply.
Do not convert an amount between routes. Bioavailability, formulation, sterility, monitoring, and clinical context differ by route. Research-use context only; independently verify every cited source.
The adequate intake is a total dietary target rather than a supplement dose. Current retail packaging is commonly 100-1000 g powder or 240-capsule containers.
Supplementary research context only. Not medical advice or a treatment recommendation.
