as long as your not taking any harsh drugs and your taking care of yourself your liver will be working hard to repair its self. I know its kind of nasty but as long as your stool is normal your liver is doing it's job. you will know if your liver is in trouble, your stool will look 9 different kinds of abnormal and smell like death and your eyes will be jaundice. (yellowing of the whites of eyes).
And another thing that really helped my husbands liver quickly rejuvenate was making him this drink in the mornings and you put it all in a blender.
2 grape fruits just the juice
1 whole carrot
1 whole kiwi
2 apples
2 bananas
2 oranges
and you can also receive great benefit from pomegranate too.
blend and down it. I know it will taste kind of ucky but he always told me that it made him feel great and his liver thanked him for it. Hope this helps
