Methylene Blue
3,7-bis(dimethylamino)phenothiazin-5-ium chloride
A synthetic compound with over 130 years of medical history — originally developed as a textile dye and later adopted as one of the first modern pharmaceuticals. At the low doses used in nootropic formulations, Methylene Blue is emerging as a promising cognitive enhancer that supports mitochondrial energy production, neuroprotection, and mental performance through unique mechanisms not found in other supplements.
What Is It?
Methylene Blue (MB) was first synthesized in 1876 and has one of the longest medical histories
of any compound used today. It has been used as a treatment for methemoglobinemia, a malaria
treatment, a surgical dye, and is on the World Health Organization's List of Essential Medicines.
In recent years, neuroscientists and longevity researchers have turned their attention to
Methylene Blue at micro-doses (1-10mg) for its remarkable effects on mitochondrial function,
brain energy metabolism, and neuroprotection — creating significant interest in its potential
as a cognitive performance compound.

How It Works
Methylene Blue works through several unique mechanisms:
- Mitochondrial electron carrier — MB can accept and donate electrons directly in the mitochondrial electron transport chain, acting as an alternative electron carrier that improves cellular energy (ATP) production efficiency — even when the normal chain is compromised
- Cytochrome c oxidase enhancement — increases activity of Complex IV in the mitochondrial chain, the rate-limiting step in cellular energy production
- Antioxidant cycling — MB cycles between oxidized (blue) and reduced (colorless) states, neutralizing reactive oxygen species and reducing oxidative stress in brain tissue
- Cerebral blood flow — research suggests MB increases regional cerebral blood flow, improving oxygen and glucose delivery to brain tissue
- Neuroprotection — has demonstrated protective effects against tau aggregation and amyloid formation

Side Effects & Considerations
Methylene Blue has an extensive safety record at medical doses, with important notes for
nootropic use:
- Will temporarily turn urine blue or green — this is completely harmless and expected
- May temporarily tint skin or mucous membranes blue at higher doses
- IMPORTANT: Do NOT combine with serotonergic medications including:
- SSRIs or SNRIs
- MAO inhibitors
- Tramadol or other serotonergic drugs (Risk of serotonin syndrome even at low doses)
- Do not combine with Kanna/Sceletium extracts for the same reason
- Not for use during pregnancy or nursing
- Those with G6PD deficiency should not use Methylene Blue
- Consult your healthcare provider before use if on any medications
- The 5-10mg doses in Natty Addy are within the nootropic dose range — stay within recommended serving guidelines

Typical Dosage Range
1mg – 10mg daily
The nootropic dose range for Methylene Blue is 1-10mg — significantly lower than pharmaceutical doses used medically. Research suggests a hormetic dose response where low doses are beneficial and higher doses may be counterproductive. Natty Addy provides 5mg (tablet) or 10mg (shot) — stay within these guidelines and do not exceed recommended servings. Best taken earlier in the day to align with
natural energy rhythms.
Research Notes

- Tucker et al. (2018) — Randomized controlled trial published in Psychopharmacology found low-dose Methylene Blue significantly improved sustained attention and short-term memory in healthy adults.
- Atamna & Kumar (2010) — Research in Aging Cell established Methylene Blue's mechanism as a mitochondrial electron carrier and its neuroprotective effects against age-related mitochondrial decline.
- Bhatt et al. (2021) — Review in Neurochemical Research documented Methylene Blue's emerging role in
cognitive enhancement and its potential therapeutic applications for neurodegenerative conditions.
