By supporting both central and peripheral circadian clocks, our Circadian Sleep represents an innovative, restorative approach to promoting healthy circadian rhythms, resulting in multiple benefits for whole-body health.

A central circadian clock located in the brain helps regulate our sleep-wake cycles. We also have peripheral circadian clocks that govern essential biological processes, such as blood pressure and kidney function. But aging and other lifestyle factors can disrupt circadian clocks. Circadian Sleep combines melatonin with a novel citrus peel extract to help encourage healthy function of both central and peripheral circadian clocks.

Circadian clocks exist in virtually every cell of our bodies and are organized hierarchically, with the central clock setting the pace by regulating healthy sleep-wake cycles.

30 liquid vegetarian capsules

Suggested Use

Take one (1) capsule daily, before bedtime, or as recommended by a healthcare practitioner. Melatonin is naturally secreted from the pineal gland at night, and should be taken at night for optimal results.
