Entersogel 90gm Tube

Two ingredients and nothing else: a polymethylsiloxane polyhydrate gel suspended in purified water. It passes through the digestive tract gathering up medium-weight molecules as it goes, then leaves in the stool rather than entering the bloodstream.

The 90 g tube is the smaller pack — a sensible size for a short course, for travel, or for keeping one in the bag and one in the cupboard. Tasteless, so it goes down easily with water.
