I believe you're thinking of B12, which is actually made by microbes in the soil, not animals. Herbivores have these microbes in their guts, and carnivores get their B12 by eating herbivores, but supplement manufacturers bypass the animals and cultivate the microbe in the lab.From what I have read in the past humans need certain B vitamins that don't exist in plants so they need to take vitamin supplements in order to be healthy. Well, the supplements are made from animals so that tells me we are omnivores, not vegetarians.
Interestingly, humans also have these microbes in our bodies, but they're apparently too far down the digestive tract to be of use. This suggests we may at one time have been capable of surviving on a vegan diet without supplements, but that our bodies changed once we were able to reliably get meat. (The appendix is also thought to have played a role in digestion when we ate more plants.)
The American Academy of Pediatrics' position is that well-planned vegan diets are appropriate for all stages of life. I'm not vegan myself because I'm not willing to deprive myself of the pleasure and convenience of consuming animal products entirely, but I do generally go for a vegetarian/vegan option if one is available. I don't preach to people about what they should be eating, but I will correct people who misstate the facts as I believe people (including those who are listening) have the right to be able to make an informed choice.
