We are about six months into our use. We have tried all of them, of course we don't like the smell - oat is the strongest, but as I say "pinch your nose with a paper clip" and that's the worst of it 😉. It's a great product, it's good for the bowels, less bloating, and it makes you feel better. Especially my husband liked this goodness 😉 (after the "ball" - super refreshment). Try it, because medicines cost much more 😔.
