Get the B-complex and put a LOT in her water. B will flush through their system and out if not used, so it is not dangerous like fat solubles like D and E.
If you can give her a sub-cutaneous shot of the stuff, you'll get it there faster, but I pull it out in a syringe and shoot it into the water supply too.
