This is a very rough example of how we can link the categories and tags ‘filters’ to a diagram of the body and its various systems and functions.

When you hover over a body system, a popup with keywords relating to that system will appear with a button to the page of those products. We can make it popup in Greek depending on which heading language is hovered over.

I think we need to add ‘man’ and ‘woman’ and to show, e.g. menstrual cramps, prostate etc as relevant to that gender. 

What we show on this diagram is dependant on what supplements products are being sold and what part of the body they affect.
