> Cruciferous vegetables and certain beans are also rich in choline, and other dietary sources of choline include nuts, seeds, and whole grains. From https://ods.od.nih.gov/factsheets/Choline-HealthProfessional/ https://ods.od.nih.gov/factsheets/Choline-HealthProfessional... And in regards to B12, > It has long been assumed that B12 is produced by bacteria in the large intestine (aka the colon), but since B12 is produced below the ileum (where B12 is absorbed), it is not available for absorption. This theory is reinforced by the fact that many species of totally or primarily vegetarian animals eat their feces. https://veganhealth.org/intestinal-bacteria-as-b12-source/ https://veganhealth.org/intestinal-bacteria-as-b12-source/ I don't blame you for taking a supplement instead.
