  1. Hey! Id like to remind you all that you DO NOT NEED to consume animals to get b12.
    B12 is only naturally found in soil. Because we live in a hygienic society, and cattle is mostly fed non organic food (that does not contain b12) it is actually injected into cows so that we then consume it! So maybe try to investigate where that b12 in your beef is coming from.
    SO, getting b12 form supplements is about as natural as getting it from supermarket meat.
    (this goes out to any potential vegan that is scared that they’ll get sick)

  2. This is such BS. Heavy research shows most doctors and nutritionist disagree on everything about side-effects. Google searches will give you 200,000 diferring opinions.

  3. Vitamin B12 is conspiracy by the meat industry.
    I don't believe in this vitamin B12 at all.
    Why this vitamin B12 available only in animal products?
    Total lie

  4. What about extremely high levels of B 12 ? Could it possibly mean that the cells are not accepting B12 at all and hence suggestive of a deficiency ?

  5. YOU ARE SOOOOO SOOOOO GREAT … Thank you!! I´ve got pathophysiology and pathology oral exam next month and your videos help me a lot !!!

  6. been vegan for 9 years never took b12 in any form not once never had any of the symptoms…..but whenever something oges wrong with my body i keep thinking oh maybe its b 12 deffeciency …..so recnetly i've been having inflamed gums and tongue and it goes away and comes back…so i was thinking could it be it? oh maybe i'm just allergic to flouride in toothpaste and water? its not not bad its just uncomfortable and it has nothing to do with gum deasease …..but i never not once had any neurological symptoms evryone mentions

  7. Treatment = pills and injections. How about swapping out some high glycemic, high fiber plant products for some soil building, non intestinal permeability causing, pasture raised ruminant meat?

  8. I was diagnosed with vitamin b12 deficiency. My doctor said my levels were very unusually low for my age. I'm 25 and I eat plenty of meat, eggs, and dairy. I dont have a whole lot of energy but I've gotten the rounds of b12 injections and I take supplements now and I really dont notice anything different. I was also quite low in D3 and iron so I take supplements of those as well. Still dont notice a change. I dont really know what to make of these vitamin deficiencies.

  9. "The only organisms to produce vitamin B12 are certain bacteria, and archaea. Some of these bacteria are found in the soil around the grasses that ruminants eat; they are taken into the animal, proliferate, form part of their gut flora, and continue to produce vitamin B12."

    You don't need meat, you need dirt.

  10. Lithium Orotate plays a role in B12 transport into cells.  Cobalt is an essential trace element and a central component of the vitamin cobalamin, vitamin B12

  11. Also (PPIs) drugs can reduce Vitamin B12 level, because the intrinsic factor needs Acidic Media to do it's function.
    + Taking Metformin also can decrease Vitamin B12 level

  12. The great thing for vegans is there are foods and plant based milks that are fortified with Vitamin B12 so this condition can be easily avoided (:
