I watched that episode, and while I too have questions regarding the claims made, I would have been interested to see the evaluation measures and results in detail. re not finding any significant difference, if I were analyzing the raw data I wouldn't be taking statistical significance too seriously anyway, given such a tiny sample size.

DRI=MINIMUM eg bit.ly/1vgQclQ
99% don't meet these. meds/lifestyle can affect levels
status can be low in ms & other cond'ns
'but my results are normal'. typical panels don't test all
deficits occur in 'normal' range
