My mother has had her gall bladder removed from gall stones, can she take Calcium Gummy vitamins?

My mother has had her gall bladder removed about a month ago, because of the reoccurring stones, and has also had kidney stones in the past. I finally got her to start taking those adult gummy vitamins (better than nothing, cause she hates taking vitamins, makes her sick) now I'm realizing there isn't any calcium in her diet (nor is there calcium in the regular gummy vitamins), especially at her age (60's). Can she go ahead and start taking these gummy calcium vitamins with her regular gummy vitamins everyday?
