Love, love, love! So very thrilled to have found methylene blue in capsule form. I had a very bad experience with stained teeth. Took months for it to fade. Thank you Alpinia for this amazing product. I will be purchasing again!

I tried using liquid Methylene Blue from Amazon… it was a mess staining everything including my tongue and teeth! I was very happy to find your product (referred by ChatGPT)

Love the Methylene Blue 20 mg capsules. Prior to learning about Alpinia and their offerings I was using liquid Methylene Blue and what a mess and inconvenience it was beside having the problem of potential spills. It's worth paying a little more for a great product.
