15 mg methylene blue per two-capsule servingMethylene Blue Complex pairs 15 mg methylene blue with 600 mg NAC and 100 mg L-theanine per serving. It also includes vitamin C and six B vitamins, including folate and B12.
Folate comes as L-5-MTHF and B12 as methylcobalamin. This is a broader formula than methylene blue alone, with the amounts and vitamin forms detailed in the Supplement Facts.
Two capsules provide 15 mg methylene blue, 600 mg N-acetyl-L-cysteine and 100 mg L-theanine. NAC is the short name for N-acetyl-L-cysteine. The formula uses a methylcellulose capsule, with rice flour and microcrystalline cellulose as the other ingredients.
Each serving includes 100 mg vitamin C, 400 mcg DFE folate as L-5-MTHF and 200 mcg B12 as methylcobalamin. Vitamins B1, B2, B3 and B6 are also included. The adult directions allow two capsules daily, morning or night, or as directed by your healthcare physician.

Customer experiencesI’ve been taking these MEGNETA Methylene Blue Pharmaceutical Grade Capsules before work for about 6 months and they’ve become part of my morning routine. What I like most is the steady, controlled energy and focus it gives me. I stay engaged throughout most of the workday without the weird spikes or crashes I’ve gotten from other things. It feels pretty chill overall — calm but ready to work, which is exactly what I was looking for. I take it in the morning and notice the effects kick in without any harsh stimulation. My energy stays even and my focus is clearer for the majority of the day. It’s not an intense “wired” feeling; it’s more like a smooth, sustained alertness that helps me stay on task. One thing worth mentioning: I do pee green after taking it. It’s noticeable but doesn’t bother me — I just assume it’s part of how the product works. Everything else about the experience has been positive so far. If you’re looking for something that supports steady focus and calm energy without the rollercoaster effect, this has worked well for me. I’ll keep using it and update if anything changes. — Jonathan Kayser
I don't know if it works yet.. the toilet shows blue.. I'm making diet changes along with this too early to tell I think.. I do not take it daily.. about 2 - 3 times per week. When I opened the new jar/seal, it stank. Just be warned of that for sure.. update may 2026 This is one of the supplements I use and I notice a significant difference. I still take it 2 to 3 times per week and I can tell when my body is responding to it. I'm never going to take it every day but it is useful for sure! — Ozzy
I really like this product, and it does seem to help my energy levels, but how is it not staining all my internal organs blue? Could that be bad? I don't know. — Adam A. Wynn
I absolutely love how it gave me energy and focus throughout the day but it made me very dizzy and lightheaded so unfortunately I had to stop taking it. — Brandy Watson
This product makes you concentrate better. You’re more alert. I suggested anyone that has problems concentrating like I have great product. — Melissa o cables
I have been using this product for almost a year. I have noticed increased energy. I would say that it was definitely effective within the first three days. I noticed a change in my energy level. I would definitely suggest taking methylene blue in the morning and not at night. — Stegosaurus purse
