Not for: People who want a nootropic-style cognitive product, and anyone who eats eggs and meat daily and likely already meets the adequate intake.

What the AI looks for in Choline Vitamin Supplements

Elemental choline vs compound weight
Read the choline amount, not the salt weight: bitartrate is about 41% choline, alpha-GPC about 40%, and citicoline about 18%. A 500 mg capsule of choline bitartrate delivers only about 200 mg of actual choline.
Daily target
The adult Adequate Intake is 550 mg for men and 425 mg for women (450 mg in pregnancy), counting food. Most people need to top up, not replace, dietary choline.
Upper limit
The adult UL is 3.5 g of choline per day. Above this, low blood pressure and fishy body odor become likely.
Form matches goal
Use bitartrate for basic intake, and citicoline or alpha-GPC for cognition-focused use. The cheap form is fine for nutrition, but the cognition research centers on the other two.

Brands that matter

  • NOW Foods: Covers bitartrate, alpha-GPC and choline-inositol forms.
  • Jarrow Formulas: Known for citicoline.
  • Thorne: Offers phosphatidylcholine.

What to avoid

  • Labels that list only compound weight with no elemental choline amount
  • Very high doses that cause a fishy body odor (TMA)

Questions

Is lecithin a good choline source?

It's weak: lecithin is only partly phosphatidylcholine, so you need large amounts to get meaningful choline.
