Thanks again for the info.
I read this on your original posting, which inspired me to check my pH again(first morning urine). It's still at 6.2, where it's been for as long as I've been checking it, abt 1.5 years.
I've been on 100-200mg/day Iodine in Lugol's for almost 4 months now. About a month ago I installed an R/O filter and have used only this water for consumption, so my fluoride /chlorine intake should be much reduced.
So, with both the (long-term?) supplimentation of Iodine and decrease in other halogens, the pH remains the same.
BTW, last year my homeopath tried several different approaches to getting my pH up (calcium-type suppliments, veg. broths, pumpkin seeds, etc). None had more than a temporary effect.
