How to Take

Medical Disclaimer

Recommended dosage, active amounts, other details

Doses for choline vary significantly.

Typically a dose of 250mg to 500mg is used for general health purposes once daily.

For mechanisms through acetylcholine, the choline should be pulsed in high doses acutely as higher doses are partitioned to the brain to a greater extent. 1-2g is typically used.

Doses should be titrated to suit the individual, as too high of a dose at any given time may give the user a headache. It is suggested that doses start out at 50-100mg daily and that users adjust upwards in accordance with their tolerance.

Human Effect Matrix

Unlocked for Examine members

The Human Effect Matrix summarizes human studies to tell you what effects Choline has on your body, how much evidence there is, and how strong these effects are.

Full details are available to Examine members.
Grade Level of Evidence
Robust research conducted with repeated double-blind clinical trials
Multiple studies where at least two are double-blind and placebo controlled
Single double-blind study or multiple cohort studies
Uncontrolled or observational studies only
Level of Evidence
? The amount of high quality evidence. The more evidence, the more we can trust the results.
Outcome Magnitude of effect
? The direction and size of the supplement's impact on each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
Consistency of research results
? Scientific research does not always agree. HIGH or VERY HIGH means that most of the scientific research agrees.
