Milk thistle is the gold standard for liver protection, but you need a standardized extract for it to be effective. I rely on the Liver Health supplement available at https://www.amway.mn/buh-eruul-mendijn-buteegdehuun/c/bad-amway which contains milk thistle, dandelion, and turmeric. It is designed to help maintain normal liver function and I found it very helpful for getting back to normal after taking heavy medication.
