The potential benefits of methylene blue are diverse and may seem too good to be true. Methylene blue acts as a powerful antioxidant with seemingly better cellular repair capabilities than vitamin C.
Methylene Blue and Mitochondria
Mitochondria are often referred to as the “powerhouse of the cell. They are specialized, energy-producing structures found inside nearly every cell in the human body. Besides producing about 90 percent of the energy the body needs to function, mitochondria play a crucial role in cellular communication. They provide the building blocks for our genetic material and control the life cycle of cells by determining which ones are healthy enough to keep and reproduce and which should be flagged for destruction and cleared away. High-functioning, healthy mitochondria are imperative for both physical and mental well-being.Methylene blue works by directly interacting with the mitochondria. Its antioxidant properties can scavenge and neutralize harmful free radicals produced as mitochondria create cellular energy or adenosine triphosphate (ATP). Mmethylene blue also has a unique property that allows it to cycle electrons, meaning it can accept and donate electrons. This property is important because it ultimately reduces damage to cells by reducing oxidation and free radicals.
Researchers have found that methylene blue can help with many conditions related to mitochondrial dysfunction, including aging skin. In addition, unlike other antioxidants such as vitamins C, E, and curcumin, methylene blue is lipophilic, which means it is fat-soluble and can cross the blood-brain barrier. Researchers have found that mitochondrial dysfunction can lead to neuroinflammation and oxidative stress, and thus, they believe methylene blue could be a viable treatment for some neurodegenerative diseases.

Mitochondrial-Specific Antioxidants Improve Skin Cell Aging
It’s well-known that antioxidants are potent combatants that help protect the skin and slow aging.Researchers tested methylene blue using skin cells from healthy middle-aged donors and those diagnosed with a rare genetic disease, progeria, that causes children to age rapidly. Methylene blue outperformed three other antioxidants and improved age-related symptoms in the cells of both progeria patients and healthy donors.
Over the four-week experimental treatment, skin cells had decreased cellular damage due to oxidative stress, a reduced rate of cell death, and increased cell division. According to the researchers, the methylene blue stimulated mitochondrial health and addressed the root cause of skin aging.
“Our work suggests that methylene blue could be a powerful antioxidant for use in skin care products,” Kan Cao, senior study author and associate professor of cell biology and molecular genetics at the University of Maryland, said in a news release. “The effects we are seeing are not temporary. Methylene blue appears to make fundamental, long-term changes to skin cells.”
May Slow Brain Aging and Improve Neurological Diseases
In addition to aging skin, researchers believe methylene blue can increase ATP production in the brain and lower the concentration of free radicals.Alzheimer’s disease, one of society’s most feared neurologic impairments, involves abnormal protein accumulation that forms plaque around brain cells. Inflammation and oxidative stress are also prime contributors to the disease.
Additional Research
The research involving methylene blue is ongoing and extensive. The antioxidant effects on aging skin and brain health briefly describe the many benefits researchers have documented in recent years.Risks and Side Effects
Methylene blue should be taken under a doctor’s watch, even though some forms are available without a prescription.Besides more benign side effects like a blue tongue and blue urine, there are certain risks when taking methylene blue, especially in higher dosages.
- Those taking any drug with serotonergic activity (e.g., an SSRI, SNRI, MAOI, or TCA) due to possible serotonin syndrome, which is potentially fatal.
- Those with glucose-6-phosphate dehydrogenase deficiency, which could lead to severe anemia.
- Pregnant women or those who may become pregnant. The FDA has assigned it a pregnancy class X rating.
- Those with known hypersensitivity to methylene blue or any thiazine dye.
- Those with hepatic impairment, since methylene blue is extensively metabolized in the liver.
- People with renal impairment.
