Hi, I wonder if someone have an idea why Milk Thistle cause blurred vision on the next day I took it? I do have some liver problems such as fatty liver and I have toxic buildup. In other cases, when my liver have a hard time, I never get blurred vision. I do know that milk thistle is high in histamine and sulfur. From histamine I do know that I don't get blurred vision when it's high. I don't know about sulfur. Recently a blood test showed high potassium (I don't take potassium supplements) and high iron saturation (51%). Some minerals are low. Does anyone have an idea? Thanks.
