Nutricel Supplements Methylene Blue Capsules Review: Two Months, No Blue Mouth
Two months on 12mg USP grade methylene blue capsules. What changed, what didn't, and who should skip them.
The Nutricel Supplements Methylene Blue Capsules are worth buying if you want methylene blue without the liquid mess. Each capsule is 12mg USP grade, third-party tested by Eurofins, with vitamin C ester for absorption. After almost two months I noticed sustained energy and no stomach issues. Buy it if dosing drops put you off.

How this review was made: written from my own video review of this product. Every opinion here is my own, from using it myself.
Quick Verdict
After almost two months of daily use, the difference is sustained energy with no spike or crash. Sustained energy is probably the best way I can explain it. No stomach discomfort, no interactions with the rest of my daily stack.
Buy if you:
- Want methylene blue without staining your mouth, teeth, or countertop
- Already run a daily stack (aminos, multivitamin, ashwagandha) and need something that plays nice with it
- Train and work in the same day and run out of gas by late afternoon
- Care about third-party testing and USP grade over the cheapest bottle
Skip if you:
- Want to feel it on day one. I didn’t. This took weeks of daily use before I could point at anything
- Need a flexible dose. The capsule is fixed at 12mg, so you can’t titrate down the way you can with drops
- Take prescription medication without running new supplements past your doctor first

I Didn’t Know Much About Methylene Blue Going In
Methylene blue kept showing up in comments on my videos, and I realized I had no framework for it. What I was looking for was simple: more energy, more focus, more sustainability. That’s it. And the more I read, the more the Nutricel Supplements Methylene Blue Capsules fit what I was looking for.
The manufacturer markets this as mental focus and clarity. Three things in the capsule matter. The methylene blue itself supports energy at 12mg per capsule. The vitamin C ester is there to complement absorption, so you’re getting more of what you paid for. And the organic cacao brings polyphenols and antioxidants. So you get the best of both worlds in one capsule instead of three separate bottles on the counter.
The part that sold me on capsules over liquid? No blue mouth. Liquid methylene blue stains teeth, clothes, countertops. The capsule is pre-measured and sealed. That’s a practical win every single morning.
What It Won’t Do For You
This isn’t a pre-workout and it doesn’t hit like one. Nothing happened the first week. Nothing dramatic happened the second week either. The results I’m describing showed up gradually over almost two months of daily use, which is a long runway if you’re the kind of buyer who wants a verdict by Friday.
The fixed 12mg dose is the other limitation worth knowing. A lot of people experimenting with methylene blue like to start very low and work up, and drops let them do that. A capsule doesn’t. You take 12mg or you don’t take it. For me that was fine, but it’s a real tradeoff and nobody’s going to put it on the label.
And obviously, this sits in a category where you talk to your doctor first, especially if you’re on prescription medication. I’m telling you what happened with my stack, not with yours.
Where Methylene Blue Capsules Sit Next To Everything Else
The format decision comes down to one tradeoff: drops let you titrate your dose; capsules mean you never fish a stained dropper out of a glass at 6am. I’ve got a morning routine that already includes essential amino acids, a multivitamin, and ashwagandha, so slotting in one more capsule costs me nothing. Measuring drops into a glass would have cost me something.
The quality side is where this brand separates itself. USP pharmaceutical grade, third-party tested by Eurofins for identity and purity, manufactured in an NSF-certified GMP facility in the United States. No artificial dyes, no maltodextrin, no cellulose, no rice bran. Plant-based vegetarian capsules, no gelatin. In a category that has a reputation for sketchy sourcing, that documentation matters more than the marketing does.
One more thing worth knowing that you can’t see on the Amazon page. This sits around #8,750 in Health & Household with more than 3,000 bought in the past month, and the price has been steady for the past three months. So you’re not catching it at a spike, and you’re not waiting on a sale that may or may not come. Check the current price here.
Two Months On My Daily Stack
No stomach discomfort, no adverse impacts, no interactions. That’s the headline from almost two months of taking these alongside a stack I don’t like to mess with. I take a lot of things. Essential amino acids, multivitamins, ashwagandha. New supplements have gotten crossways with that lineup before, usually in the gut, usually within a few days. This one didn’t.
The 60-count bottle at one capsule a day is a two-month supply, which lines up almost exactly with how long I’ve been on it. That’s a useful thing to know going in: one bottle is roughly how long you need to run it before you can say anything about whether it’s doing something for you. Anyone judging it at the two-week mark is going to shrug and move on.
The capsules themselves held up fine on the shelf in my kitchen. Vegetarian shells, no clumping, no staining anything in the bottle. Nothing to report there, which is the point.
More Energy, More Readiness, More Stamina
The clearest thing I can point to: by week six, I was getting through a morning lift and a full afternoon of editing without hitting the wall I’d been hitting around 3pm for months. That’s the whole verdict, and I’d rather say it plainly than dress it up.
It shows up across the board, not just in one spot. Exercise, work, or just projects I’m working on around the house. I’m getting through the day with greater ease. Sustained energy is probably the best way I can explain it, and I say sustained on purpose because there’s no spike and no crash to it. It isn’t caffeine. It doesn’t feel like caffeine.
Do I think the vitamin C ester and the cacao are doing heavy lifting on their own? Probably not individually. But the formulation means I’m not sourcing a separate antioxidant, and I’m not dropping capsules because absorption is an afterthought. For something that costs me five seconds every morning, the tradeoff is zero.
Pros
- Noticeable sustained energy and stamina through the day after almost two months of daily use
- No stomach discomfort and no interactions with my amino acids, multivitamin, or ashwagandha
- Capsule format avoids the blue mouth and staining that comes with liquid methylene blue
- 12mg USP grade, Eurofins third-party tested, NSF and GMP certified facility in the US
- Vitamin C ester and organic cacao in one capsule instead of separate bottles
Cons
- Slow burn. Nothing obvious in the first weeks, so you’re committing to a full bottle to judge it
- Fixed 12mg dose with no way to start lower or adjust the way drops allow
- 60 capsules at one a day means you’re reordering roughly every two months
Frequently Asked Questions
Do you take it with food or on an empty stomach?
I take mine in the morning with the rest of my stack and it’s never bothered me either way. The organic cacao acts as a food-based excipient, which probably helps. If you’ve got a sensitive stomach, food is the safer starting point.
Will it turn your urine blue?
Blue or greenish urine is a known and harmless effect of methylene blue at supplement doses. The capsule avoids staining your mouth and teeth, but it doesn’t change what happens downstream. Worth knowing so it doesn’t catch you off guard.
Is it vegetarian or vegan friendly?
The capsule shell is plant-based and free from gelatin, so it works for vegetarians. There’s no maltodextrin, cellulose, or rice bran in it either, and no artificial dyes. If you read labels closely, this one’s clean.
How should you store the bottle?
Keep it sealed in a cool, dry spot out of direct sunlight, same as any supplement. Mine lives in a kitchen cabinet and the capsules haven’t clumped or discolored over two months. Don’t leave it in a hot car or a steamy bathroom.
