Hi, ! I think it's great that you are taking charge of your health and working to take the best care of your body you can.
I would definitely talk to your doctor about staying on your creatine as you pursue HepC treatment, just to be safe. A trusted pharmacist might have some helpful insight as well. Some literature states that continuing to take creatine while treating HepC is fine, while others recommend stopping all unregulated supplements, so, really, consulting your physician is your best bet.
I wish I could give you a straight "yes" or "no" answer, but each person is unique and someone who knows your situation and medical history would be in the best position to offer you advice.
Keep us posted on how treatment is going, if you feel comfortable doing so.
Best, Erin, HepatitisC.net Team Member.
