💊 What it does
Choline is an essential nutrient (conditionally essential — the body can synthesise small amounts but not enough to meet full requirements) that plays critical roles in cell membrane structure (as phosphatidylcholine), neurotransmitter synthesis (acetylcholine — important for memory and muscle control), liver fat metabolism, and one-carbon metabolism alongside folate and B12. Choline deficiency causes fatty liver, muscle damage, and in severe cases cognitive impairment. It is one of the most commonly under-consumed nutrients in plant-based diets.
👤 Who needs it
Vegans and plant-based eaters — the richest dietary sources of choline are eggs and liver, both absent from plant-based diets. Pregnant and breastfeeding women — choline is critical for foetal brain development and requirements double during pregnancy. People with NAFLD or liver conditions. Those with MTHFR variants (choline partially compensates for impaired folate-methyl cycle). Athletes — choline is depleted during endurance exercise.
🥦 Food sources first
Best plant sources: soya products are by far the richest plant source of choline — tofu, tempeh, edamame, soya milk. Other useful sources: shiitake mushrooms, broccoli, Brussels sprouts, peanuts, almonds, quinoa, red kidney beans. However, achieving adequate choline from plant foods alone requires conscious effort and regular soya consumption.
🗓 When to supplement
For vegans and plant-based eaters who do not eat soya regularly. During pregnancy. When fatty liver is a concern. When dietary assessment shows consistent shortfall.
🏷 Best form to look for
Choline bitartrate is the most common and affordable form — effective for general choline needs. CDP-choline (citicoline) and alpha-GPC have superior brain bioavailability and are used for cognitive applications. Phosphatidylcholine (from soya lecithin) is the food form and well tolerated.
⏰ When to take it
With meals — choline supplements can cause nausea on an empty stomach. Take consistently at the same time each day.
