Repashy calcium plus is marketed as an all in one suppliment. However evidence shows that calcium supplementation can compromise vitamin content when mixed. I’m not sure how repashy manages their recipe so I use repashy calcium plus in conjunction with a vitamin supplement that I alternate between feedings. Example on Monday I dust with repashy calcium plus, Tuesday with reptivite. Wednesday no suppliment Thursday calcium plus, Friday nothing, Saturday reptivite, Sunday calcium plus. Once a month I use the repashy vitamin A and hold off on any supplements for a few days. Remember you can over supplement especially with vitamin A.
