Roll Call does not check drug interactions or assess personal safety.
A phospholipid found in egg yolk, soy, and other foods, and a major building block of cell membranes. It also serves as a dietary source of choline.
Why it’s used
Taken by some for liver support or cognitive function, and used in supplements partly as a source of choline.
What the evidence is for
supporting liver-related outcomes in small clinical trials.
What the evidence says
NIH ODS notes that choline, of which phosphatidylcholine is one dietary form, is an essential nutrient involved in liver, nerve, and cell-membrane function. Direct evidence that supplemental phosphatidylcholine improves liver or cognitive outcomes in healthy people is limited, drawn mostly from small trials in specific conditions rather than the general population.
Dose studied
1–3 g — small trials examining liver-related outcomes.
Context
Small trials examining liver-related outcomes have used doses in the range of roughly 1 to 3 grams per day, but sample sizes are small and results are not consistent enough to generalize.
