Is that the RDA for a normal person or one who has had WLS and has malabsorption issues? You will find that you need to double what a normie's RDA is to get the benefit of what you are swallowing.
I take the calcium citrate with magnesium and D from vitalady. Two in the morning and two at night and I am good to go. My labs are good!
I know that Twinlabs has a chewable citrate as well - I saw it at Wegman's.
