Hello Dr. Rynne, I Use Cialis As Needed (not Everyday

Hello Dr. Rynne, I use Cialis as needed (not everyday as recommended) and I started taking a supplement called "volcano" from a company named Force Factor (Boston MA 877-909-7874) The product label lists Nitric Oxide Muscle Matrix (has L-Citrulline, Agmapure, Agmatine Sulfate, L-Norvaline, CON-CRET Creatine HCL, L-Methionine, L-Glycine). The Cialis label say do not take if using a "nitrate" drug. Can I take the Volcano supplement or not? I use the Cialis to assure my capability for intimacy with my special lady.
Regards,
