You are one of the people I was talking about: you belive you can just add a few vitamins and minerals here and there and call it a day: that is not how it works!
Example: vitamin C in supplements is only ascorbic acid. But the real vitamin C is a "complex" and contains multiple other vitamins INSIDE of it+ stuff surrounding the complex.
You cannot break down meat into minerals and vitamins if they don't have them in the first place.
