Versuchsvorschrift

As we discovered and disclose in Example 2, L-carnitine magnesium valproate, another embodiment of the present invention, is a white solid having a melting point of 77.2° C., different from the melting point of L-carnitine. The 1H-NMR spectrum of L-carnitine magnesium valproate (FIG. 3) differs from that of the starting materials (i.e., L-carnitine and valproic acid) and confirms the structure. L-carnitine magnesium valproate is nearly odorless and free from objectionable taste. L-Carnitine magnesium valproate is soluble in water, and aqueous solutions of this salt provide bioavailable L-carnitine, magnesium, and valproate.
