Having a bit of a craving for sweets I tried Werther's original sugar-free butter candies.
The sweeteners are Isomalt, Acesulfame K
However within a week I developed gout [which I sometimes get during the strawberry season]. Unpleasant, but I do have a rapid cure without using any drugs. Whether it was connnected to to the sweets I do not know; but I made no other diet changes in the period.
Hi and welcome. I can't say I have suffered from it or any direct ill effects of the sweetners other than loo visits. You may need to "fix and retry" to see if it is the sweets
