Elements
Chemical forms, review status and supporting notes — one hub per element. Rankings live on each form page, by unit price, not across forms.
Counts are the whole catalogue. What you can buy depends on your shipping country, set at the top of each page.

The elements above are where we started, not where we stop. The same method is being extended to the rest of the supplement shelf. Nothing below has a page or a number yet.
There are no dates here: an ingredient goes live when we can compute a number for it that we can defend. How the number is made.
