Milk thistle causes irritability

So I've been supplementing on Liver Rescue the last week; it contains milk thistle, dandelion root and other stuff that's supposed to help your liver because i realized I have a fatty liver from high carb/sugar intake. The next couple of days I've been absolutely moody, depressed and aggressive. It's been hard to sleep lately so now I am taking a small amount of the stuff to reduce the side effects but can anyone think of why this supplement has given me anger issues and mood swings? Tweet
