Abstract

The invention provides non-hormonal vitamin D conjugated to apelin proteins that result in increased absorption, bioavailability or circulating half-life when compared to non-conjugated forms. In some embodiments, the vitamin D targeting groups are coupled to the apelin proteins via the third carbon on the vitamin D backbone.
