The Takeaway
Traditional chemistry states that salts like lithium orotate should break apart into individual ions as soon as they hit water. These clusters, called PINCs, stay bound together much longer than anyone expected. This physical structure might be the reason why lithium orotate seems to enter the brain more effectively than other lithium salts. Standard theories of ion-pair behavior cannot explain why these clusters remain stable in dilute solutions. This discovery explains why different forms of the same drug can have such radically different effects on the body.
From the abstract
Lithium orotate appears to exert biological effects distinct from those of other lithium salts, raising the question of how lithium and orotate might travel together from gut to target tissue. Standard ion-pair theory predicts only weak contact pairs that live for picoseconds in dilute aqueous solution, insufficient to account for transport as a functional unit. We propose that lithium orotate supports a qualitatively different class of chemical entity, which we call a Partially Ionised Nano-Clu
