Exploring the Potential of Methylene Blue
Updated Mar 25, 2026
This will probably be the most controversial substance listed here. Let me be clear: I am not telling you what to do, nor am I suggesting you follow in my footsteps. What drew me to this compound was its nootropic profile and its reported antibacterial and antiviral activity. Four years ago, my liver enzymes were mildly elevated, so I decided to test it. Four months later, my ALT had not only normalized but dropped into what I would call the ideal range. My AST, which was already within normal limits, also improved. I’ve taken MB on and off for more than four years and have experienced no adverse effects.
Nootropic Function and Mitochondrial Support
Methylene blue has shown potential neuroprotective effects at low doses by acting as an electron donor within the mitochondrial electron transport chain. That matters because mitochondria generate adenosine triphosphate (ATP), the energy currency that powers virtually every human function. When ATP production declines, physical and mental performance usually follow.
Research suggests that methylene blue can donate electrons to coenzyme Q and possibly to cytochrome c, which may increase cytochrome oxidase activity (complex IV) and oxygen consumption. It has also been associated with enhanced heme synthesis. In addition, MB may stimulate glucose metabolism under low-oxygen conditions and increase mitochondrial production of NAD+.
Methylene Blue and Mitochondrial Function
Methylene blue is capable of reacting with oxygen to form water, which may reduce the generation of superoxide radicals during oxidative phosphorylation. It can also capture leaked electrons produced by mitochondrial inhibitors, helping preserve metabolic rate by bypassing blocked points in electron flow and improving mitochondrial respiration. Studies indicate that MB crosses the blood-brain barrier and, at low doses, can function as an electron shuttle in the mitochondrial transport chain. That mechanism is one reason it continues to attract attention in discussions of memory support and neuroprotection.
Experimental Study on the Effects of Methylene Blue
One experimental study in rats explored the effects of MB on cognitive function. The animals underwent either permanent bilateral carotid occlusion (2VO) or sham surgery, followed by daily administration of 4 mg/kg USP methylene blue or saline for one month. Behavioral testing included open field, visual water maze, and odor-recognition tasks.
The results were notable. The 2VO rats performed poorly in the visible water task, but showed no major differences in general motor activity, visually guided swimming ability, or odor recognition. Daily MB administration reduced the deficits in visual learning and memory associated with cerebrovascular insufficiency.
During training in the visual water task, which involved three different discrimination problems, all animals eventually reached a criterion of 8 out of 10 correct trials. But the 2VO animals took longer to learn each problem and performed worse in a more difficult memory probe. The animals receiving daily post-session MB performed significantly better than saline-treated subjects during both training and the memory probe.
This study offered early evidence that MB may reduce learning and memory impairments associated with carotid occlusion. The findings suggest it could have relevance for conditions tied to chronic cerebral hypoperfusion, including mild cognitive impairment, vascular dementia, and Alzheimer’s disease. https://pubmed.ncbi.nlm.nih.gov/25079810/
Exploring the Biomedical Potential of Antarctic Mumijo
Mumijo, a traditional medicine widely used in countries such as Russia, Mongolia, Iran, and Kazakhstan, has long been recognized for immune-stimulating and antiallergic properties and has been used in the treatment and prevention of infectious disease. In one study, researchers investigated the biomedical potential of a Mumijo-related substance collected in Antarctica from snow petrels, Pagodroma nivea. Chemical analysis showed that the fossil samples were composed of a mixture of glycerol derivatives.
Neuroprotective Effects of Mumijo Extract
In vitro experiments were conducted to examine the effect of the Mumijo extract on cortical neurons, particularly against amyloid peptide fragment Aβ25-35, a known inducer of apoptosis. The results showed that the extract produced a strong neuroprotective effect on cortical neurons, shielding them from the damaging effects of Aβ25-35.
In addition, the fraction enriched with glycerol ethers and wax esters promoted growth in permanent neuronal PC12 cells. These findings suggest that this Mumijo preparation has meaningful neuroprotective activity, likely tied to glycerol ether derivatives. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3139983/
While many of the products mentioned above can be found with a simple online search, Mumijo can be harder to locate. Mumijo can be obtained here:
