Lipo-Gen from Metagenics was suggested to us from our doctor to take together with Beta-TCP to help clean my liver. Both my husband and I have been taking them and we couldn't be happier with the outcome. We typically take them at the start of each season together with Vitamin D. If the results on the outside were great, I can't even begin to imagine how good they were for my insides. We've actually suggested them to lots of our friends and family members and we've heard great things from the ones who've tried.
