Call you doctor ASAP. This could be a very serious condition.
If there is only a small amount of bleeding, the only symptom may be dark or black streaks in the stools. If larger amounts of bleeding occur, symptoms may include:
Black, tarry stools
Bloody stools
Light-headedness
Paleness
Stop the vitamins. Treating yourself when you have liver disease and hepatitis C is not something that should done.

If you have decided to wait to see if it is something your taking why not go to the drugstore, you can buy things to check if it is blood. Might ease the worring.
Good luck, just remember nothing takes the place of a doctor.
I'd call your Doc sooner rather than later. Having had a burst varix (a bulging vein in the stomach/esophagus due to HepC and cirrhosis) I learned that GI bleeding can be a life threatening event. Not trying to diagnose you here, but in my case it was 3 days in the ICU and transfusions. yes, black stools were involved. I'd recommend you seek medical advice.
my study nurse said no iron supplements for me. i'd talk to your doctor. take care. belle
You are correct in assuming that an iron supplement may cause the stool to be black. However any bleeding in the digestive tract can also have the same effect. Possibly stop that particular vitamin and see if the problem rectify"s :0 itself. If not you should be seen by your doctor.
Also it is usually not a good idea to supplement iron with HCV..as iron levels and/or iron storage is often high with HCV.
