Methylene Blue 1% solution 3.4 Fl Oz - 100 ml | Ultra High Purity | USP Pharma Grade Ingredients - Third-Party Tested | Formaldehyde free | Glass Bottle | Heiltropfen®

This product is effective in many areas I am nearly 85 and now feel at least 20 years younger. Sleeping better, more energy great all round..

Been taking this for 6 weeks now and feeling amazing!I have bad fatigue and brain fog and this Methylene Blue has almost completely fixed it, I have alot more energy everyday, even on days where I have 2/3 hours sleep i don't get brain fog or anything, amazing product!One thing to look for in Methylene Blue is the heavy metals in the cheap products, this one is tested for all of that so very safe

Seem like a quality product, just make sure to do adequate research before using, I'd start with a low dose to avoid any side effects

I'm impressed with this methylene blue. It's effective in multiple ways, including for energy, attention, focus and mood, among other health benefits. Delivery was fast too.

Excellent and definitely has a very positive effect regarding tiredness,brain fog and inflammation 👍👍👍👍

Okay so...Methylene Blue is taking the world by storm and rightly so. I ordered this and received it the same day. Packaged well and no damage to any packaging or product.The product itself is well worth reading about. I did around 3 months of research before opting to purchase and use. Bear in mind there are always going to be those who berate and criticise the product because they're paid shills and have interests in big pharma. My dosage is 10 drops in a glass of water every morning (this bypasses the blue tongue and blue lips risk). Warning, this will turn your urine blue but dont worry, its normal.Great seller and product and will be buying again.

This is why I left a poor review - and what I asked chat GPT;I changed my brand of methylene blue, with no gap in administering it - the previous brand turned my urine a turquoise blue colour, this new brand does not… the colour of my urine is normal with the new brand. What is caused this difference? Is the new brand of methylene blue not as pure? What could cause this?That’s a very insightful observation — and you're absolutely right to question it. The change in urine colour (or lack of it) following a brand switch of methylene blue (MB) may indeed reflect a difference in formulation, purity, or even bioavailability. Here's a breakdown of what could be going on:✅ What Normally Causes Blue or Green Urine with Methylene Blue?Methylene blue is a blue dye, and when administered (especially orally or IV), it's typically excreted in urine in a way that turns it blue or greenish-turquoise, depending on pH and concentration. This is completely normal and expected.🧪 So why isn't your new brand doing that?Here are the most likely explanations:1. Lower Concentration or Reduced BioavailabilityThe new brand may have less active methylene blue per dose than the previous one, even if the label says otherwise.If it's an oral form, bioavailability (how much is absorbed into your system) can differ a lot depending on formulation — excipients, coating, fillers, etc.If the drug is being metabolised differently due to formulation, less MB may reach your bloodstream, and thus less is excreted via the kidneys to tint the urine.➡️ What to check: Compare the labelled dosage, form (e.g. USP vs BP vs compounded), and excipients (if listed).2. Different Salt Forms or PurityMethylene blue can be formulated as methylene blue trihydrate, anhydrous, or as various salts (e.g. chloride).Some forms are more potent or better absorbed than others.The purity grade may also differ: for example, pharmaceutical grade is purer than laboratory or industrial grade, which may include more impurities or stabilisers.➡️ Impure or oxidised MB might not colour the urine as intensely or consistently.3. Different Additives or StabilisersSome formulations include reducing agents or pH stabilisers that affect the dye’s colour expression in the body.Others might include coatings that delay or reduce absorption in the GI tract.➡️ This can change how much MB is absorbed and whether it appears in urine in its blue form or after being metabolised.4. Metabolism or Urinary pH DifferencesLess likely in your case (since the only thing that changed was the brand), but urinary pH affects the shade of blue/green that appears.MB is partially metabolised to leucomethylene blue, which is colourless. If the formulation favours this metabolism, it may reduce the colour seen.⚠️ Is it less effective if it doesn't colour the urine?Not necessarily — but it could be.If methylene blue is being:poorly absorbedpoorly formulatedor sub-dosed, then yes, it may not be exerting the same pharmacological effects (e.g. MAO inhibition, NADPH oxidase inhibition, etc.).If you're using it therapeutically (e.g. for mitochondrial support, methemoglobinemia, neuroprotection, etc.), it's worth investigating further.

This methylene blue doesn’t seem as potent as my other methylene blue I have even though it states it is the same concentration. So I’m not so sure about this one or not. I think I can still feel it working but my other one I use I feel great my mood is lifted and focus is great. Still has the bitter taste but doesn’t die the cups or utensils I use as much as my other one either.I do still think it works though. I use 20drops 2 times a dayRegardsAdam smith
