It helps regulate your natural sleep-wake cycles, or circadian rhythms, and encourages the delta-wave sleep that is crucial for physical and mental recovery
The biochemical one is that B vitamins, B12 in particular, are cofactors in the same one-carbon and methylation chemistry that the lipotropics feed into, so they complement the methionine cycle described above
