Before vegans get cocky, though… Floppy ears are cute, on a bunny. Not so cute on your spinal cord. The inverted rabbit ear sign. See how it kind of looks like an upside down bunny with floppy ears? Well, that’s not what your spinal cord’s supposed to look like.

Why did this woman have spastic ataxic quadriparesis, a sensory polyneuropathy, and diffuse spinal cord swelling? Because she was a “strict vegetarian lady.” I assume they mean strictly vegetarian? Then again, maybe she was just quite the disciplinarian. Either way, people eating plant-based diets must take vitamin B12.

Reports continue to pour in from all over the world, whether you’re a vegetariana estricta, a streng vegane, or eating végétalienne, you’d have to be crazy not getting your B12. Literally.

31-year-old stock trader turned paranoid psychotic. But not because he was schizophrenic; because he was vegan, and didn’t eat B12-fortified foods or take a B12 supplement. Suffered for three years before his doctors figured it out.

Kiss me, I’m vegan. No, thank you. 41-year-old woman, vegan for two and a half years without B12. Kiss a vegetarian, and taste the difference? Before, and, after she took her B12. Cleared up in no time. Vegans taste better, when they take their B12.

    1. Please feel free to leave any questions for me on this topic below and I’ll answer them as soon as I possibly can. Also, check out the 16 other videos on B12 and feel free to explore any of the other 1,449 subjects I cover in my videos.

  1. 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!)

  2. 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?

  3. 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!

  4. I’ve been having problems with my finger nails having ridges from the base to the end. I read this can be a b12 deficiency, but I’m in the recommended dose and I get it in soy milk. After a year in a plant based diet could it be another deficiency?

    1. Hey Roy, thanks for writing! The answer is no. The liver has a supply of B12 that lasts for several months beyond stopping your intake of B-12 -containing foods. You’re find with starting one now.
