Methylene Blue
METH-ih-leen blue
One of the oldest synthetic compounds in medicine — boosts mitochondrial energy production and supports cognitive clarity.
Also known as: Methylthioninium Chloride
FDA approved for: Methemoglobinemia treatment · Surgical dye
Last reviewed: April 2026
What It Does
Methylene blue acts as an electron shuttle in your mitochondria. When your cells' power plants are sluggish, it provides an alternate pathway to keep energy production flowing. At low doses, it enhances cognitive clarity, supports neuroprotection, and acts as an antioxidant.

Who Should NOT Take This
• Taking SSRIs or MAOIs (risk of serotonin syndrome)
• G6PD deficiency
• Renal impairment
• Pregnancy
Drug Interactions
• SSRIs — DANGEROUS: risk of serotonin syndrome
• MAOIs — DANGEROUS: risk of serotonin syndrome
• Serotonergic drugs — do not combine
Pregnancy: Do not use during pregnancy. May cause fetal hemolytic anemia.
Clinical Details
Compare With Similar Peptides
All three support mitochondrial function through different mechanisms. Methylene blue is the electron shuttle, NAD+ is the energy currency, rapamycin triggers cleanup.
NAD+
A coenzyme in every cell that powers your mitochondria — levels drop with age, and restoring them supports energy and cellular repair.
Rapamycin
The most studied longevity compound — activates cellular cleanup by telling your cells to switch from 'growth mode' to 'maintenance mode.'
