acts as an artificial electron cycler in the mitochondrial electron transport chain, bypassing Complex I/III to reduce Complex IV, increasing ATP production and reducing ROS at low doses. It is also a potent reversible MAO-A inhibitor (RIMA). The dosing is strictly hormetic: at low doses (0.5–4 mg/kg) it is antioxidant and neuroprotective; at high doses ( 300mg or ~4mg/kg+) it flips to pro-oxidant and cytotoxic. 30mg is on the higher end of the low-dose range (72.5 kg × 0.5 mg/kg = ~36mg) but still well within the beneficial zone. The biggest practical constraint is the brain zap risk: MB must be taken every day alongside serotonergic medications, missing a single day while on SSRIs causes severe brain zaps. Two hard requirements before use: G6PD deficiency test (hemolysis in positive carriers) and USP pharmaceutical grade only (industrial grades contain arsenic and lead).
