Arrived earlier than expected and the product seems intact.
It came quicker than I was expecting and it looks like all the pills are there. I only got it yesterday, so I don't know how effective the gum pills are.

Very good for breath but caused some sour mouth
I have dry mouth which makes me prone to bad breath. I’ve experimented with chewing these before bed (after brushing) or in the morning (also after brushing). I tested my breath using a cloth mask and also did “blank” tests on days when I did not use the product. Chewing before bed greatly reduced morning breath but left me with some sour mouth, which makes me worry a bit about tooth decay. I’ve switched to taking in the morning and have been happy with the results.

Lips & mouth sore?
Mouth and lips became sensitive and sore after using this product 2x per day for 3 days. Maybe I’m allergic to one of the ingredients? Don’t know. It’s day 3 of soreness and waiting for it to subside.

Doesn’t work
I’ve tried to for three weeks and I’ve tested and it does t work. I can taste this mint in my mouth and it still smells funky. I’ve had customers and employees tell me my breath smells. I don’t drink coffeee and I brush my teeth for 10mins straight every morning and night and I also use mouth wash and I use three tabs throughout the day and it does nothing for me.
