Most people don’t hear about choline, but it’s one of those nutrients your brain and liver really need. Choline helps build cell membranes, makes the neurotransmitter acetylcholine (important for memory and muscle control), and supports liver fat metabolism. Low choline can show up as memory problems, muscle damage, or a fatty liver — so it’s worth paying attention.
If you’re pregnant or planning pregnancy, choline deserves a spot on your radar. It helps fetal brain and spinal cord development. For adults, getting enough choline supports thinking, mood, and keeping liver fat in check. Athletes and older adults also notice benefits in muscle and brain function when they meet needs.
Food first: eggs (especially yolks) and liver are the richest sources. A single large egg often provides around 100 mg. Other good options: beef, chicken, fish, milk, soybeans, tofu, cruciferous veggies, and nuts. If you eat a serving of eggs, a serving of beans, and a bit of fish across the day, you’ll cover a lot of ground.
Daily targets (Adequate Intake): adult men ~550 mg, adult women ~425 mg, pregnant ~450 mg, lactating up to 550 mg. Many people fall short, especially vegans and some women.
Supplements: forms include choline bitartrate (cheap, basic), CDP-choline (citicoline) and alpha-GPC (better for cognitive goals). Typical supplement doses: choline bitartrate 250–1000 mg/day; citicoline often 250–500 mg/day; alpha-GPC 300–600 mg/day. Start low and split doses if needed.
Pick a form based on your goal: use food or bitartrate for general intake; pick citicoline or alpha-GPC if you want a stronger brain effect. Look for third-party testing (USP, NSF) and avoid mega-doses without medical advice.
Side effects and safety: taking too much can cause a fishy body odor, sweating, low blood pressure, or digestive upset. The tolerable upper limit for adults is about 3,500 mg/day. If you’re pregnant, have liver disease, or take medicines that affect acetylcholine or liver function, talk to your doctor before starting supplements.
Quick practical tips: add one egg a day, try tofu or edamame as snacks, cook liver once every couple weeks if you like it, and consider a supplement if you follow a strict plant-based diet. No routine blood test tracks choline levels for the public, so watch symptoms and diet patterns instead.
Want a simple starting plan? Eat at least one high-choline food daily and consider a low-dose supplement (250–300 mg) if you’re vegan or pregnant — but run it by your healthcare provider first. Small changes can make a big difference for brain and liver health.
