Phosphatidylcholine (PC) is a major building block of your cell membranes. Brain cells, liver cells, and nerve cells rely on it. It’s also one of the main ways your body gets choline — a nutrient critical for memory, focus, detoxification, and healthy fat metabolism.
Why I care about it clinically:
• supports liver function and bile flow
• helps move fat out of the liver (very relevant with fatty liver trends)
• needed to make acetylcholine (your memory and learning neurotransmitter)
• important for brain development and cognitive health
• influences inflammation and immune signaling
Many people are unintentionally low — especially if they don’t eat eggs, avoid animal foods, have gallbladder issues, struggle with brain fog, or have sluggish liver markers.
Food sources matter (egg yolks are a big one), but sometimes intake + demand don’t match, which is where supplementation can be useful in the right person.
If you’ve been dealing with brain fog, poor fat digestion, or stubborn liver markers, this is one of the nutrients worth evaluating.
And as always — don’t just add supplements blindly. Context matters.
