Does milk thistle help the liver?

Milk thistle has historically been used for the liver, but the US National Center for Complementary and Integrative Health says there isn't enough high-quality evidence to reach definite conclusions about its effects on health conditions. It is not a treatment for liver disease, so see your doctor about any liver concerns.

How long does a bottle last?

A bottle has 120 capsules, which is 60 serves of 2 capsules. At one serve a day it lasts about two months. Do not take more than the recommended dose to make up for a missed day.
