Obviously you do care, or you wouldn't post your comment.

This article is not full of information. Your acticle certainly has some. I'll just point out one very clear point here: B12 is not produced by animals. It is a bacteria that is digested by animals that eat certain plants. Since 99% of meat in the US is factory raised, those animals are given B12. I cut out the inefficient middleman and just take a B12 supplement myself, just like I do by eating plants, rather than spending a fortune to raise crops to feed animals that are raised for slaughter. I just eat the plants.
