здоровый продукт из первых рук

Appropriate translations for the Russian "iz pervykh ruk" here would be direct/directly as Katerina suggested, or "(directly) from the source". It has nothing to do with "first-hand" regardless of what your dictionary says. The devil, as always, is in established usage. Thus, first-hand experience is good. "First-hand product"--what the heck is that? Why it is so, I have no idea. It just is.

Definition of 'first-hand'
http://www.macmillandictionary.com/dictionary/british/first-...
'first-hand experience/information'.

I don't know if it could be used in connection with products or foods, but Google does return a few matches in the figurative meaning though.
