Milk thistle is not going to cut it for liver support on oral steroids. You'll need a more robust plan like TUDCA, ALA, NAC, choline, and inositol as well. You're liver isn't the only organ being stressed either, and you are best off getting full organ protection products like DGA organ st.
what on earth is "milk thistle" going to do to protect your blood pressure, cholesterol, kidneys etc?? you need an all in one protectant that will keep you covered... .dga organ st is the most complete all in one you can find... here is the link.. https://www.amazon.com/DGA-Nutraceuticals-Organ-ST/dp/B0762B5KBG
they both have around the same amount of ingredients, which is over 40 and you just never see that anywhere... they both have tudca in them so there's no need to add more and you clearly cant go wrong either way
