water has a ph of 7. i would not be drinking a substance that has a ph of 2. 5 -- very acid or even 9. 5 -highly alkaline. i am not sure what kind of filter is doing this. of course your stomach is highly acidic anyway. i really don't know if acidic or alkaline water will effect your medications namely since i don't know what medications you are taking. refer this question to an "expert" -- your pharmacist (someone who knows what you are taking or any any of these drugs are ph dependent for absorption. this is a good question. i am sorry that i don't have a good answer.
does water ph affect medication? i have a filter that produces water with a ph from 2. 5 to 9. 5.
