For me the answer would be no...my minerals was so imbalanced, if I tries to guess at what I would have needed I would have never known really how much...for instance I would have maybe taking 22.5 mg of zinc daily and I truly need 22.5 times 5. And with the calcium I was so far off the charts, that again I would have maybe tried FDA allowance or maybe even double that...but again I was in need of so much more. It is a balancing act.
This is how far I have come with the Ratio of CA/K ( calcium to potassium, 1st hair analysis was at 204, 2nd was at 141 and now the 3rd is at 50 should be a the ideal ratio of 4...got a ways to go...but getting there...show is my stress levels, much lower...my new growth in the roots of the hair is much less gray /white...I am finally absorbing calcium...YAY!!!!
PS: Every ones needs are different, so I feel it is a big guessing game.
