High Blood Pressure and Carditone

I stopped the Carditone and started my meds and then a few days later I started taking the Carditone along with my meds. I take my blood pressure meds early in the morning and the Carditone at 8pm. My blood pressure was 120/75 this morning, so I think that the Carditone is assisting in my blood pressure. Yesterday my blood pressure was 124/74 and I know that my blood pressure hasn't been this low for a long time.

I take 40 mg of Lisinopril and 2.5 mg of Amlodipine Besylate for high blood pressure. How does one tell his VA doctor about Carditone? Do I stop taking my medications when I start taking Carditone? I had a TBI while serving in the Air Force and was in a coma for 16 days. Most VA doctors frown on taking a supplement for high blood pressure and I'm not sure on how to go about changing to Carditone.
