To all who have a problem with really bad breath. I have searched many years for a cure for the problem. I have tried everything known to man. I finally found something that has been working for me and I am so thankful to God for finally finding something. I believe through research that this problem is definitely caused by our digestive system. Certain foods are not being digested correctly. We are missing an enzyme or digestive acid. Anyway, if you have the same terrible breath problem please go to a vitamin store or online and buy a bottle of Betaine (HCL) plus pepsin. 625 betaine plus 100 pepsin. Research by me says take only one a day in the morning after breakfast. Let me know if it works. If it does then thank the Lord. Good luck and hope it works for you . John D.
