Methylene Blue
About
About Methylene Blue
Methylene blue is a century-old compound originally used as an antimalarial and antidote for methemoglobinemia, now studied for cognitive enhancement, mitochondrial support, and neuroprotection. At low doses it acts as a mitochondrial electron carrier, improving cellular energy production. It has shown promise in early Alzheimer's research and is used off-label by biohackers for focus and memory. Pharmaceutical-grade formulations are essential for safety.
Science
Mechanism of Action
At low doses, functions as a mitochondrial electron shuttle between NADH and cytochrome c, bypassing complex I/III dysfunction and increasing ATP production; also inhibits MAO and nitric oxide synthase at higher doses.
Dosing
Typical Protocol
0.5–4 mg/kg oral or IV; low-dose protocol: 5–15 mg oral 2–3x per week. Avoid high doses and SSRI interactions.

Regulatory
Legal Status in 2026

It is not FDA-approved as a finished drug product, but compounding is explicitly permitted under federal law. Quality and sterility standards vary by pharmacy — look for PCAB-accredited compounders.
