Choline — 250 mg

💊 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.

⚡ Interactions & combinations
Works alongside folate and B12 in one-carbon metabolism — ensure adequate B12 and folate intake alongside choline. High doses of choline (above 3.5 g/day) cause a fishy body odour from TMAO production — the 250 mg supplement dose is well below this threshold.
🛡 Safety notes
Very well tolerated at 250–500 mg/day. The UK adequate intake is 400 mg/day for adults. High doses cause fishy body odour and GI upset. The upper limit is 3.5 g/day.
🌿 Vegan note
Choline bitartrate is plant-based (synthesised). CDP-choline is synthesised. Alpha-GPC from soya lecithin is plant-based. Phosphatidylcholine from soya lecithin is plant-based.
Moderate evidence
Good evidence, though not unanimous across all research.
