I prefer to give my body what it needs from food sources so our human iOS can do what it does best. Synthetic is not the same, & detoxes still leave your body with missing pieces. Red meat & raw dairy from the best sources provide your body with Cysteine, an amino acid that plays a HUGE role in ANTIOXIDANT production (precursor to glutathione) the master antioxidant and detoxifier. Other sources that yield good return on your investment are eggs, pork, turkey, and seafood.
