Golden
A gold band means the route is mapped. The essential vitamins, minerals, amino acids and fatty acids — plus creatine, whey and caffeine, which are studied to the same depth. Their pages carry an animated anatomical route: the named transporter that lets the compound in, where it is stored, what it does there, and which door it leaves by. An entry without a band is not worse — it is less mapped.
