I am using all blackmores vitamins and supplements i guess its from australia. I am in singapore and it does goes through our authorities
It depends on the supplements, but none of the ones you're taking should do it. You don't say which multivitamin you're taking, and some companies aren't very good. Milk thistle isn't an herb you take regularly, you only take it when you want to treat certain liver problems. There are supplements that can cause liver problems -- standardized kava has been implicated, for example, in 5 cases, though the evidence isn't great it's generally bad for the liver given they drink it daily in Polynesia and have no such problem, but they don't use the standardized version. Taking too many Chinese supplements can be a problem, as they have developed problems with unscrupulous suppliers including liver toxic contaminants -- some of the highest levels of severe liver disease in the US are in the Chinese community. But you're not taking those supplements. One way to find out if you're buying low quality and therefore possibly tainted supplements is to stop taking all your supplements and see if in a month or so the problem is gone. My guess, though, is the problem lies elsewhere. It could also be a one-time anomaly. Do you take any medications or use street drugs or alcohol?
