No, the fruits do not contain vitamin B12. In this comparison of B12 content in fruits, it is examined whether any common fruits actually contain the vitamin, and how their amounts (if any) compare to other plant-based sources. The consistent conclusion in many analyses is that B12 is not present in reliable amounts in most fruits. B12 is produced by certain bacteria and is more commonly associated with animal-derived foods and fortified products than with fresh fruit. Which fruits actually have B12? According to published analyses, no widely recognized fruits provide dependable B12. Some reports mention trace or inconsistent detections, but such results vary depending on the sample and method, so they cannot be regarded as a reliable measure of B12 content in fruit. When B12 is found in plant-based contexts, it is often at very low levels and may result from contamination or the presence of B12-like compounds (cobalamin analogs) rather than a usable form. How much B12 could be obtained from fruit? Due to the lack of consistent B12 content in fruit, any detected amounts are usually microscopic and cannot be used to establish a reliable estimate. The variability between samples means there is no standard fruit-based quantity to plan for, and reported levels—when available—are far below a meaningful threshold for interpretation. Reliable vegan sources of B12 include fortified foods and supplements. Common options are fortified plant milks, fortified cereals, nutritional yeast labeled with B12, as well as B12 vitamin supplements. For those following a plant-based diet, checking product labels and choosing fortified options or supplements (and consulting relevant guides) can help ensure a steady, dependable B12 supply outside of fruit.
