Ok so Mr Chicken or Mrs Cow don’t use a B12 spray in the mornings but the feed that they are fed is supplemented with vitamins and minerals, containing B12.
The feed supplement business is a million dollar industry, and factory farmed animals need more of it because of the horrific conditions they are kept in making them nutrient deficient, just like humans who are living in poverty with poor living conditions being fed poor diets.
Even free range and grass fed ruminant animals such as cattle and sheep are sometimes given Cobalt an element which they need to make B12 in their bodies…why?
Because our soil is becoming less and less nutrient dense and there is less Cobalt found within it, so even a grass fed animal won’t be able to make all the nutrients it needs.
So the next time someone says ‘well the vegan diet isn’t natural because you have to take B12’ ask them where they get their meat from and if they know that the animals they are eating are actually given supplements themselves.
