Review: Missing Packaging Raises Concerns - I received my Methylene Blue Solution packaged only in the white cylinder, without the outer white box that normally contains all the product information. This omission makes me question whether the item may have been tampered with.

### ⭐⭐⭐⭐⭐ Review
*by M***L on 18 January 2026*

I tried it and have felt a good results. My teech had some plaque and I noticed it changed to whiter. I read why it cleans the teeth and I found it is used in dental procedures. It gives energy, and I use it for a course of month 10 mg a day in the morning. I think 10 mg is good to protect the probiotics in your stomach since it is anti microbial substances. Do not take it at night which you may not sleep. I take it in the morning on empty stomach.
