Dear Listerine Zero,

I was very excited to see that you’ve come out with a variety of Listerine without all those calories, while still maintaining a great flavor. As someone who counts calories and watches her weight, I’ve found that every little bit counts. Now I’m able to have as much delicious Listerine as I want, guilt free! Also, fewer upset stomachs with this new variety! Many compliments on the new great product!

I’m interested in the additional ingredients of Listerine Zero, but couldn’t seem to find them on the bottle I purchased. Where can I find the nutrition facts for the Fresh Mint variety of your product? Particularly, I’m interested in the sweeteners used, and the suggested serving size for adults and children.

Thank you,
Linda Wilson

Hello Patricia,

I’m a little shocked at your response. I have been using Listerine for years, and this is the first I’ve heard of it being untested!

Does Walgreens know this? They are running a great special on Listerine right now, and I doubt they would promote an untested product. Should I switch to Walgreens brand mouthwash? I don’t like their flavors as much as yours, but I would hate for Listerine to negatively affect my family’s health due to lack of testing.

I really hope you can verify that this product is safe, because I just bought four bottles of the Clean Mint Listerine zero for my husband and I, and two of the Original Orange Juice Listerine for my son Aaron and my daughter Denise. They LOVE it in the morning! It gets them riled up and ready to go, and I would hate to give that up. I think my son is your biggest fan! I am laughing out loud right now!

Thank you for sharing my email with the other team members, I would love to talk to them on the phone, but I’m currently suffering from a bit of laryngitis.

P.S. Are there plans to make a zero-calorie version of the Orange Juice Listerine? My son is getting a little pudgy.

Dear Paige,

What happened to Patricia? She was forwarding my email to your product team and they were going to get back with me about some details. Who should I ask for when I call? You or Patricia?

Hi Paige,

Dr. Roseboom thinks my voice should return by the end of next week. My throat is pretty inflamed, so I’ve had to stop with the Listerine for now, even though the Listerine Zero is easier to stomach. I’m really eager to hear what your product team comes back with in terms of serving size and proper testing, though, and I think Patricia was handling that.

Can you please put me back in touch with Patricia?

Sincerely, Linda Wilson

P.S. Who are Johnson & Johnson? I think you have me confused with someone else!
