Sublingual glutathione together with prescribed medications

Patient: I had my period last may 9 and i am on my 3rd day. because i want to get pregnant, my OB prescribed Ovulet 5mg twice a day starting today with foli-5 once a day. aside from this, i am planning to take a sublingual glutathione. my question is: is it safe to take the sublingual glutathione 3x a day together with those prescribed by my OB?

Doctor:
