I bought this, knowing I need to work on my hydration, based on all of the super-positive reviews. I've been using the drops daily for nearly a month now (and at the suggested 3x/day dosage - sometimes more) - and I don't notice a difference. In fact, if anything, I feel more dehydrated now. I'd used the BioTrace Elite electrolytes previously and they did make me feel like my hydration had improved. The only reason I switched was when I went to reorder I noticed Cellfood in the list of electrolyte products, read the reviews and thought I'd give it a go. I will note that I don't taste anything with the CellFood product in water, while the BioTrace product has a bit of a taste to it. Anyway, I wish this had been as wonderful for me as it has apparently been for others.
