Bottom line

Read Off Label grades Choline as A (8.0/10) based on strong evidence, med benefit magnitude, and a low-risk safety profile.

Widely under-consumed in populations low on eggs/liver.

Typical use: 425 mg/day women; 550 mg/day men; more in pregnancy/lactation (alpha-GPC or CDP-choline for nootropic use) — OTC.

What this is

Widely under-consumed in populations low on eggs/liver. Critical in pregnancy for fetal brain development. TMAO concern at high doses is overstated.

Mechanism

Phospholipid synthesis (phosphatidylcholine membrane component); acetylcholine precursor; methyl donor; lipid/liver metabolism

Dose & route

425 mg/day women; 550 mg/day men; more in pregnancy/lactation (alpha-GPC or CDP-choline for nootropic use)
