I think it depends on how may per day you take.
at 1 (50mg) per day I was fine.
but at 3 per day I felt sick, could feel my liver was swollen,
started to look yellow too. not a good feelin'
stick to 1 per day, take some milkthistle herb too.
this will help protect your liver, witch is the only organ in the body that can repair or regenerate it's self. so dont' worry too much.
