I'm new and reading the 21-day PB book. I've done lots of reading on the website and in other areas.

One of my misgivings about this philosophy of the primal blueprint is it seems at time to be contradictory. One of the main sources of contradictions so far is vitamins.

I just read in the book that vitamins are unnecessary and actually are worse for you. But then I come to the site, where very expensive vitamins are sold.

How can you say that they are unnecessary and then sell them on the site?

Just looking for answers
