  • A very well tasting Vitamin B12 resource is the old British well known Marmite. Easily taken in soups or breakfast porridge but also thinly spread on toast.

      I don’t know about good tasting :) but yes indeed, a good source of vitamin B12.

    i LOVE Marmite and eat it every morning,  – not sure i’m getting enough B12 though, starting to get worried after watching this vid…i suffer from severe back problems! (never taken supplements, but now i will!)

  • Veggie Mama

    Why don’t they add B12 to soymilk like they add Vitamin D to cow’s milk?

    • They do in the U.S., but I think in the U.K. for example, vitamin fortification isn’t allowed until the organic (bio) standards. Maybe someone out there knows more?

    • Canada’s organic “So Nice” brand has B12 and D fortified among other vitamins.

  • VeganDebi

    Is it true that B12 needs to be injected to get the full benefits???

  • Sara

    How do I get B12 for children?

  • vegandon

    Barley grass is loaded with B vitamins and including B12. Live enzymes/foods are way better then dead foods, processed foods, vitamins . . . So why don’t you mention that?

  • Sebastian Tristan

    Every time I watch B-12 deficiency horror stories, I find myself going to the fridge and getting a B-12 pill. =D

    That’s terrifying about the spinal cord. I’m quite worried I have a deficiency because my memory/concentration/brain fog is BAD. And i have a few other symptoms. Thanks for this!
