I have to agree that many dog food companies (especially the ones lacking scientists or small niche companies) won't do research on vitamins (or even do research at all!). That's why I just have to stay with companies who have done at least some research and hire experts in nutrition who have PhDs etc. |
Again, I don't see things that black and white, lots of people have smoked all their lives and never got cancer, not everyone who smokes get cancer. I'm certainly not saying that synthetic vitamins will cause cancer, but there's a lot of new research on the subject and many doctors are recommending humans avoid vitamin supplements. I'm all for research, but we need independent health organizations doing this type of research.
