Choline is the nutrient nobody talks about until pregnancy, and the richest sources are animal foods. The plant list is real but shorter, and most people of any diet already fall short.

Why choline matters, and where it hides
Choline supports cell membranes, the neurotransmitter acetylcholine, and early brain development, which is why it comes up most in pregnancy. The body makes some, but not enough to coast on, according to the NIH fact sheet, a public-domain US government document.
Primary source 01 / 04
Humans can produce choline endogenously in the liver, mostly as phosphatidylcholine, but the amount that the body naturally synthesizes is not sufficient to meet human needs
It would be easy to file choline as a vegan problem. The data says it is closer to a national one. The Adequate Intake is 550 mg a day for men and 425 mg for women, and most people miss it.
Primary source 04 / 04
Most people in the United States consume less than the AI for choline.
The practical takeaway: a vegan who leans on soy, beans, cruciferous vegetables, nuts and whole grains can reach a reasonable intake, and anyone who is pregnant or planning to be should treat choline as a nutrient worth counting, plant-based or not. A supplement or a lecithin source closes the gap when the diet does not.
Omega-3s on a vegan dietFlax and walnuts give you the parent omega-3. Turning it into the ones your brain and heart use is inefficient, which is where algae oil comes in.
Vitamin B12 on a vegan dietB12 is the one nutrient where both cited sources speak bluntly about what plant foods do not supply.
Yes, with attention. The most concentrated sources are eggs, meat and dairy, but the NIH lists cruciferous vegetables, beans, nuts, seeds and whole grains as choline-rich plant foods. Soy lecithin is another vegan source. Most people of every diet fall below the recommended intake, so it is worth building meals around these foods.
Do vegans need a choline supplement?
Not automatically. A varied vegan diet with soy, legumes and cruciferous vegetables supplies choline, but pregnancy raises the stakes because choline supports fetal brain development, and a supplement is a reasonable insurance policy then. Discuss it with a clinician.
