Inferior to some other brands as it contains magnesium stearate (which interferes with the immune system). I use it to shrink endometriomas, (from endometriosis) and for PCOS. It causes me sleeping problems but its effect is different for everybody . It excretes zinc and molybdenum so these should be taken either through food or through supplement.
