Shift work disrupts the circadian system in well-documented ways. Here's what the research has explored on melatonin's role in supporting circadian adaptation for shift workers.

Melatonin is a circadian signal, not a sedative. Understanding the distinction — and how the circadian system actually works — changes how you think about melatonin supplementation.

Melatonin 120mg sits at the high end of the studied dose range. Here's the research context, who uses it, and how it differs from lower-dose products.

Melatonin's antioxidant properties are among the most studied aspects of its biology — and are largely independent of its role in sleep regulation. Here's what the research explores.

The peer-reviewed literature on high-dose melatonin covers doses far above standard OTC products. Here's what researchers have explored and what the evidence base looks like.
