This site's own benefits section lists this specific second point: portable and easy to use.
This site describes it directly: convenient for people with busy or irregular schedules — worth reading this as a lifestyle-fit benefit, distinct from the format-simplicity benefit listed immediately before it.
Worth noting a gummy format typically needs no water to take, which is part of what this site likely means by "portable" — though this site does not make that specific no-water claim explicitly in the materials reviewed.
