The addition of minerals like calcium chloride and sodium bicarbonate is intended to enhance taste and electrolyte balance, but the source quality and processing level result in a lower score. The packaging does not indicate any significant safety concerns, but the lack of transparency regarding PFAS testing and potential microplastic presence could be improved.
