Answer 1

I work with doctors that formulate vitamins, and this has never been recognized by them as a viable method for creating formulas.  I'd move on to more traditional nutritional supplements with good science behind them.

Answer 2

SCAM!! Think about it rationally- vitamins tailored to YOUR PARTICULAR DNA?!? It's completely ludicrous. Regular supplements are fine when needed.

Answer 3

No.  The idea is absurd; although people have genetic differences, the particular amino acids required to make proteins average out to negligible difference.  Save your money -- and buy a nice steak.
