What I specifically said, was you could find some good debates about it here (and in V's forum) and that calcium hydroxide is not an absorbable form of calcium. Both statements are true. I didn't say this site 'had a problem' with the alkalizing drink, but that there were some good debates available to read.
If you search this and Vulcanel's forum you can find loads of different perspectives on whether calcium hydroxide is a good thing to supplement with. The premise behind the debates has (from my readings) continually been that an alkalizing drink doesn't necessarily address why one was acidic in the first place. Most of the chemists on these boards don't necessarily believe in supplementing with calcium at all. Calcium carbonate is a good calcium to supplement with while doing iodine because it's not absorbable and binds to the fluoride you're excreting through the detox.
