Circadian

Your circadian rhythm is set by clock genes (Per1/2, Cry1/2), and resveratrol in ResveraCel activates SIRT1, a master regulator of those genes. As DSIP supports deep sleep and Selank supports a calm nervous system, ResveraCel reinforces the molecular clock underneath. Its NR component maintains NAD+ between cycles, keeping circadian gene regulation continuously supported.

Melatonin synthesis requires magnesium as an enzymatic cofactor. As DSIP promotes deep, slow-wave sleep, Magnesium Bisglycinate supplies this substrate and helps quiet the nervous system for sleep onset. For age-related sleep changes where magnesium is often low, it's a foundational support.

DSIP promotes slow-wave sleep, PharmaGABA-250 creates the neurochemical environment for that sleep onset to happen rapidly. GABA is the brain's primary inhibitory neurotransmitter and the key signal that quiets the nervous system for sleep. Together with DSIP, they address both the neuropeptide signaling and the neurotransmitter environment of sleep initiation.

Vitamin D regulates circadian clock gene expression in virtually every cell. It supports the same Per and Cry genes that set your sleep-wake timing. As DSIP and Selank work on sleep depth and calm, D-5000 adds molecular clock-gene support throughout the body, reinforcing a consistent rhythm.

NAD+ supports the sirtuin activity that regulates your circadian clock genes, and NiaCel 400 keeps NAD+ levels elevated. NR, its active ingredient, is a direct NAD+ precursor that sustains NAD+-dependent clock-gene regulation. As DSIP and Selank support sleep and calm, NiaCel keeps the underlying molecular rhythm steady between cycles.
