I have at times used Bragg's ACV daily for months. Prob OK because hi quality. And as U know, I am an O non-secretor!
I have also used lemon juice and ACV both for months. I did less well on this because I could not secure enough hi quality lemons. I rarely tried lemon only, tho many others have done well with that [U can search past posts with the words lemon or lemon juice to find their posts abt their experiences]
One thing I do wonder based on yr post: Are you balancing the alkaline and acids well? Using just enough acid [ACV or lemon] to eliminate the chalkiness of yr drink?
For a while, I was not getting this right, and my drink was too acid. That was the prob, not the specific acid used.
Also, are U taking with meals or between meals? Especially at first, I could not handle it with a meal.
RE: calcium and magnesium supps if your drink is right 4 U, U won't need. If very little sunlight for some reason, might need D temporarily. I did for a while. Drink is both cheaper and more affordable, easier to flex to varying requirements, so why would one want to continue supps? Of course, make changes gradually, observing results!
Hope that will be of assistance!
