Kempler is confident, page-3

For many years a general term "metal balance" was used to explain how PBT2 works and a very long list of positive biochemical and histological changes were reported in the animal studies. The explanation was only a general fact that the biochemical reactions depend on metal balance and this is for sure also true.

But now there is much more specific reason: mitochondria need a good metal balance to produce enough energy for the cells and IMO this will explain better than any previous explanation all improvements found out in the animal studies.

I would think that this change in understanding where the metal balance is needed and what metals are critical ( iron accumulation) give the confidence to Mr. Kempler. Only my opinion but at least this gives me the confidence I need at this time.
