Not very. Swiss Chard has high levels of B2 and B6; it does NOT contain B12. Some studies have shown Swiss Chard to be helpful in absorbing and utilizing other vitamins so it may increase the Bioavailability of B12 if the B12 is present from another source. B12 only comes from animal sources; for vegetarians and vegans (either of which are avoiding meat) the only B12 sources come from micro organisms. Fermented foods such as Tempeh (fermented soybeans) contain B12 left behind from the healthy bacteria that is grown during the fermentation process. All vegetarian and vegan sources of B12 come only from bacteria (usually a fermentation process) or micro organisms (like what is found in some forms of algae that contain B12). Any vegetable source of B12 would be only from unwashed organic vegetables that may contain traces of insects or larvae; it does not come from the vegetable itself.
