Methylene Blue Ultra High Purity Pharmaceutical Grade Supplement. Vegan Methylene Blue Capsules For Humans With Vitamin C Ester for Better Absorption. Support Memory, Focus, Clarity, and Healthy Aging

This is a nice product and I do feel a difference when I take it, it's a little bit subtle but noticeable. It's also a good dose according to what the AI says when I consulted it in terms of not being a super high dose but just enough to have some benefits.

It came fast. It's my fault I should have read it's Amazon's choice! But I didn't realize it was only 30 capsules. My mistake I'll look for another quality brand that has 50 60 or 120 tablets for around the same price or not much more. Good product.

Definitely helps with brain fog and fatigue and will turn your pee blue so just be aware of that 🤪

Aunque un poco caro, tengo la certeza que es de grado farmacéutico y que no contiene metales pesados.

Did absolutely nothing I’m pretty well vers on peptides and other wellness products like this. In my opinion and experience this is an absolute waste of money not at all recommended.

works great far superior to other brands.

Seems to work well, really colors your urine!😁

I’ve been using Methylene Blue for quite a while, and my go to has always been the liquid form taken with a dropper. That liquid version hits fast and hard. I usually feel the mental clarity within 30 minutes, and my urine turns blue soon after, which to me is a sign it's kicking in.This capsule form by Peak Performance is more convenient. It doesn’t stain your mouth, teeth, or tongue—which is important when I have meetings or need to talk to people face-to-face. With the liquid, my mouth turns so blue it’s impossible to hide. So now, if I have meetings or I'm out in public, I go for this capsule version. If I’m working alone and don’t care about the blue-mouth effect, I still reach for the liquid due to its stronger and faster results.I’ve noticed these capsules take longer to kick in than the liquid form I take. It’s usually a couple of hours before I feel the mental boost, and my urine doesn’t turn blue until about the same time. While the dosage is supposed to be the same, taking Methylene Blue as a capsule feels about half as effective as taking it as a liquid.That said, I'm reviewing this specific product, and for a capsule version, considering the convenience and ability to be presentable in meetings, this is a great option.This product is pharmaceutical grade, which is super important when you are consuming Methylene Blue, as it helps reduce the risk of contamination, including heavy metals such as lead.
