I am so sorry, but I can't even comment on how well these work because I couldn't get over their over mouth effect (for want of a better term). Somehow these chews manage to taste even chalkier than the normal tablets, but overall just have this nebulous vaguely sweet flavor you have to chew and chew and chew to get through. The original tablets may not taste great, but at least they're easy to get down! One chew was enough for me to never try again. Gave the rest away.
