Mostly disappointed as I like many Hyalogic products. Cons: Really did not help with dry mouth for me. Seems to irritate my tongue as do the slippery elm tablets by Thayers. Pros: Tastes good. Verdict: Won't purchase again. For those wanting suggestions, I really like Thayers mouth spray and also using about 1/2 tsp of olive oil to coat the inside of my mouth before I go to bed. So, I use the olive oil right before bedtime, and the spray when I get up in the middle of the night. I don't know what impact the olive oil or Thayers may have on dental health - will have to look into that further to have a better idea and will also ask my dentist and dental hygienist to see if they happen to know.
