Calcium Orotate?

Has anyone tried Calcium Orotate? I've been taking Ezorb for the past few months and have had a tremendous energy boost (first time in quite a while) and zero side effects. Not sure how it’s affecting my bones but the increase in energy definitely feels good! However, I've heard that Calcium Orotate's (Dr Han's Nieper) absorption rate rivals Ezorb's and is less expensive. Just wondering if anyone else has heard of it or tried it.
