Lane Labs H2Go™ The Natural Alternative for Colon Health. Works Like Fiber, but Without the Bulk. H2Go tablets are small, easy-to-swallow and gentle on the system. With up to four times the surface area and volume of ordinary magnesium, the Active Magnesia™ in H2Go™ draws water into the colon like a sponge and holds it there longer, to soften stools and make elimination comfortable, easy and regular.
