The Claim

Daily supplementation with 320 mg of choline for 4 months does not result in a statistically significant increase in plasma choline levels among healthy vegans when compared to placebo.

In plain English

Taking a choline supplement daily for four months does not raise choline levels in the blood of healthy vegans more than taking a placebo.

See the scientific wording

A multinutrient supplement containing 320 mg of choline per day for 4 months does not significantly increase plasma choline levels in healthy vegans compared to placebo, suggesting either that dietary intake is sufficient, endogenous synthesis compensates, or that plasma choline is an unreliable biomarker for status.

Why this might work

The body makes enough choline on its own and gets enough from food, so adding more choline through supplements doesn’t raise blood levels because the system is already full and doesn’t need extra.

  1. Study: Assessment of vitamin A, vitamin B2, vitamin B12, vitamin K, folate, and choline status following 4 months of multinutrient supplementation in healthy vegans: a randomised, double-blind, placebo-controlled trial

    Scientists gave healthy vegans a daily pill with 320 mg of choline for four months and checked their blood. Their choline levels didn’t go up, even though they took extra. This suggests their bodies might already get enough choline from food, make it themselves, or the blood test isn’t a good way to measure choline status.
