Lipitor is of course not a vitamin. It's a statin. Vitamins are determined based on what's essential for an organism. It's a bit tricky since the body's own reserves of some vitamins can last for months, but as I recall, the determination of what's essential included observations of people nourished by IVs (and hence all nutrients could be traced).
