Vitamin B12.
Methylcobalamin — the activated, methylated form of B12.

B12 is required for methylation — the biochemical process that produces SAM-e, the body's universal methyl donor and a precursor for serotonin, dopamine, and noradrenaline synthesis. We use methylcobalamin (not the cheaper cyanocobalamin) so people with MTHFR variants still absorb it cleanly.
