Choline
VitaminsKey Benefits
How It Works
Choline is essential for phosphatidylcholine (cell membranes), acetylcholine (learning/memory neurotransmitter), and betaine (methylation). Over 90% of the population doesn't meet adequate intake. It's critical for liver function (preventing fatty liver) and fetal brain development.
Dosage & Timing
Recommended Dosage
500-2,000 mg daily
Best Time to Take
Morning or afternoon with meals
Recommended Form
Alpha GPC or CDP-Choline (better brain bioavailability than choline bitartrate)
Side Effects
Fishy body odour at high doses (trimethylaminuria). GI discomfort. May worsen depression in those with existing low mood.
Drug Interactions
May enhance effects of acetylcholinesterase inhibitors. Few negative interactions.
What Does The Research Say?
The National Academy of Sciences considers choline an essential nutrient. Egg yolks are the best food source. Research supports cognitive benefits, liver health, and pregnancy outcomes. Deficiency is widespread and under-recognised.
