How This Works
DSIP acts as a neuromodulator of the sleep-wake cycle and stress response. Preparation consistently increases delta-wave (slow-wave) sleep in EEG recordings[2], suggesting it promotes the initiation and maintenance of deep, non-REM sleep. DSIP readily crosses the blood-brain barrier to exert central effects[7] and may enhance inhibitory neuronal activity or modulate sleep-regulating brain regions. Additionally, DSIP attenuates ACTH and corticosterone release in response to stress, indicating an effect on the hypothalamic-pituitary-adrenal axis[8]. Unlike conventional sedatives, DSIP tends to normalize sleep architecture without next-day grogginess[3].
