Iron is only an issue for those that have iron overload which can be diagnosed with a group of tests. Most people with hepatitis C don't have iron overload.

Iron and Vitamin C
"Some people with hepatitis C, particularly those with cirrhosis, have above-average levels of iron in their body. Too much iron can damage organs. If these people take multivitamin/mineral pills, they should take the ones without iron. These pills usually are marketed as formulas for men or adults over 50. These people also should avoid taking large doses of vitamin C because vitamin C helps the body absorb iron.
You do not want to take iron supplements if you have hepatitis C, unless you are specifically told to take iron by your provider."

I think tt has more to do with liver damage.
Too much iron alone can cause cirrhosis.
If your liver is healthy, I'd say spinach in moderation, isn't a problem.
If you have cirrhosis, I'd stay away from any source of additional iron.
