9-ME-BC (9-Methyl-β-carboline) is a β-carboline alkaloid that promotes dopamine neuron growth, survival, and function through multiple neuroprotective mechanisms. It was identified in research as a compound capable of stimulating dopaminergic neurogenesis — the growth of new dopamine-producing neurons — making it of significant interest in neurodegenerative disease research. Methylene Blue, the second component, is a phenothiazine dye with well-documented mitochondria-targeting properties that has been used in medicine for over a century. In the brain, Methylene Blue acts as an alternative electron carrier in the mitochondrial respiratory chain, improving ATP production efficiency and reducing the formation of reactive oxygen species. Together, these two compounds address both the dopaminergic and bioenergetic dimensions of cognitive function, making this combination a subject of active nootropic research.
