----- to answer your q Ingupo Sun Harvest bottle size was 1ounce & Dr Clark's bottle size was 2 ounces.
My original BW was Sun Harvest from Sprouts here in San Diego. That's the one I got my shiny teeth from the first three days. Went thru 3 bottles of that then went to DR C's BW. I also experimented and tried raw milk with Dr Clark's BW tincture. I made sure I had a glass or two of the raw milk per day and just a little warm water with a dropper full of BW. I didn't take them at the same time. For a test I switched around to raw milk with BW for a week then went back to just BW for a week. Then I just had raw milk for a couple of days without BW. BW & raw milk seemed to work the best taken the same day. After I went thru about 2 bottles of Dr C's BW it seemed to stop working. I wasn't getting any more re-mineralization/ whitening in the dark areas & a tiny dent in my tooth stopped filling in. At about that time I got a little scared because I was loading myself with all kinds of herbs and remedies and wasn't sure so I stopped just about everything. My body functions changed when I went to the restroom. Stools went completely black for weeks so I got scared and stopped everything. I will start up again soon probably with just the Sun Harvest BW then depending on results I may add raw milk. If I get no results then I'll try DR C's BW again. I still want this to work but I got very discouraged a few months back especially with such a good start. I will post again.
I've been on and off brushing and rinsing with Celtic Sea Salt. Also I'm using the Celtic Sea Salt in a nose irrigator too. :)
