Disruption of sulfur oxidation : Excess H2S can inhibit sulfite oxidase, the enzyme responsible for converting sulfite to sulfate

Researchers should consult primary literature (Khavinson et al., 2003-2020) for protocol-specific concentrations
Its primary mechanism of action involves increasing the expression of Brain-Derived Neurotrophic Factor (BDNF) in the cerebral cortex and hippocampus, promoting neuroplasticity, the formation of new synapses, and neuronal survival
