Super small without any fillers. Dissolves fast. Do not put into a dry mouth, they require some moisture; so, drink some water, first, or something. These things will reconstitute at the first sign of moisture before dissolving %26 will stick to wherever they land in your mouth until they dissolve, unlike other sublingual. With no coating on the outside or dyes, added sugars, starches, and stuff like rosehip mixed in, makes one realize why they put that stuff in other products. This is about as natural as it gets.
