Hi I'm years late but like many of you I had problems with my breath. It's was disgusting and I could taste it. Tried everything therabreath going to the dentist, grapefruit seed extract, probiotics, tongue scraping and other crap and NOTHING Can't forget home remedies peroxide ,baking soda, chewing parsley, cleansing.I even tried blis k12 to no avail but then I decided to use my brain. They say bad breath bacteria is anaerobic which hate oxygen right?? So I used hydrogen peroxide but before you judge hear me out. I previously used hydrogen peroxide as a mouthwash but the odor and taste returned in minutes. So since I knew the peroxide was at least killing them for a short time now it was time to get my blis k12 babies in there so they could establish themselves before the evil ones came back. For the first time something WORKED!!!After I brushed and scraped my tongue I took half part peroxide an half part water . Gargled for like a min rinsed well then took 2 blis k12 lozenges 4 hours later took two more. A few minutes after I took the first set of lozenges I could still kind of taste my breath so I was a little sad and was looking for more remedies but then through out the day I noticed the taste was going away. And the taste I must say is how I judge how bad my breath is. it's crzy I taste nothing mouth feels sooo clean. So well that I didn't have to rinse my mouth again with the peroxide I just brushed flossed scraped my tongue and took 2 more lozenges. My Tongue is pinker. I'm so excited my first day but any relief is better than none. I hope this helps someone .Don't eat or drink anything for 20 30 min after taking the lozenge I suggest just so the k12 gets a chance to establish itself before you eat them so to speak lol. My assumption is that these two things didn't work because 1 the hydrogen peroxide by itself was knocking out good and bad bacteria and the bad bacteria had a chance to grow uninterrupted by other helpful ones that were killed but couldnt reestablish themselves as fast as the bad halitosis causing ones and 2 the blis k12 wasnt able to colonize due to the high amounts of bad anaerobic the weren't killed off by me simPly using regular mouthwash. But by putting these 2 babies together something lovely happened and it didn't cost me 50 dollars. I'm so happy !!try it peeps. I'm not saying its a cure cause everybody has what works for them. I suggest this if you're a healthy person suffering from bad breath odor. When I say healthy I mean upper respiratory, gum disease, nasal infections and all that other stuff has been ruled out . Just plain bad breath. Hope I helped I woke up out of my sleep just to post this to help others :) I love you all and hope everyone finds what works for them.
