Earth Harmony Methylene Blue Pharmaceutical Grade 99.99% with Dropper - Liquid Gold Methylene Blue USP Grade, No Formaldehyde - 2 Fl Oz, 2-Pack

Definitely felt like it was working on day 1. I am 53, in menopause, and very foggy headed. I swear just taking one dose made me feel clearer and calmer.

This was suggested by my doctor to increase the results of the red light therapy I am doing. This is one of the best as it has the gold that works with red light therapy. Don't be alarmed if you pee a little blue.

Love this product! Works great to keep you focused! The taste is pretty awful haha but the ingredients are pure and worth the money! It works well for most of the day!

Life changing for Me and animalsI've been getting it to my horse that has some minor neurological issues, and I have been taking it just for all around health reasons!! And as soon as I took it on a regular basis, life just became much easier, less stressful, and I do feel much much better energy wise! People talk about weird taste I don't taste anything really I just put it in my water with some lemon and it taste great!!

I do like the product, I have more feeling in my right foot where I have neuropathy and I noticed I have clearer thoughts. Although the only drawback I have is the dropper you cannot see what the dosage is because it is covered with methylene blue

I couldn’t reorder this brand last year so switched to another brand. I was grateful when this came available again. This mixes much better. Easily verifiable that it works in your system better & much longer. Those of you who use blue know what I’m talking about. Highly recommend this product.

I keep reordering this one as it has great results and, BY FAR, the best taste. I can drop this one without diluting it at all.

I've been using this methylene blue for months and because I saw an unmistakable improvement very soon after starting, I'm sticking with this brand. I suspected I had mitochondrial issues from mold exposure and other issues, and was looking for ways to help myself. Not only does a morning dose make it considerably easier to get ready for work in the morning, I'm sure it has also cut absenteeism for me. I'm most impressed with the extra energy I feel; I'm sure there are other benefits (like mood improvement) but the extra energy alone has been worth the purchase price. For those who really dislike the taste, consider filling an empty supplement capsule; this will also prevent staining of mouth and teeth (although I've never had a problem with that).
