Your body doesnt make vitamin B12 on its own
B12s role in melatonin production, a hormone responsible for regulating sleep, is believed to be significant
The first couple of weeks begin at the lower end of that range, around 6 units, before stepping up to 8 units as the body adapts
Biological activity duration: Despite the short plasma half-life, downstream effects on telomerase expression and pineal regulation persist substantially longer (days to weeks) consistent with Epithalon acting as a signaling molecule triggering longer-lived transcriptional changes rather than direct dose-response activity
Again, no consistent pattern of symptoms is seen, but infants are more prone to permanent damage than adults
