Zom B 16 Posted June 21, 2021 Crap! I have been alternating between Viactiv caramel chewables and Bari Advantage chews for about 2 months now. Had no idea the Viactivs are Calcium carbonate. That would explain why my Constipation got a little better. Less calcium absorption 😕 Share this post Link to post Share on other sites
mae7365 372 Posted June 22, 2021 I just had my 2nd set of labs completed and my blood Calcium levels are in the middle of the normal range. So I'm going to stick with the Viactiv unless my surgeon tells me differently at my 8 month appointment on Thursday. Share this post Link to post Share on other sites
