What is the right inositol dosage for mild ocd and how many times a day ?

The right dose: Inositol, one of the B vitamins, is not formally indicated for the treatment of OCD and has some interactions, including one with Lithium, that can be dangerous. The literature suggests that between 2 and 18 gm/day in divided doses can be effective. You should definitely talk with your health care provider before starting an inositol titration.
