NAD has also been shown to increase energy levels, which are often depleted after surgery or injury

DSIP# DSIP promotes delta-wave sleep through multiple pathways, none of which are fully characterized: Delta wave promotion -- increases the proportion of slow-wave sleep characterized by high-amplitude delta rhythms on EEG, the phenomenon for which it was named Serotonergic and GABAergic modulation -- sleep effects appear to involve modulation of both serotonin and GABA neurotransmission, the two major inhibitory systems involved in sleep initiation and maintenance NMDA receptor modulation -- may influence glutamatergic signaling involved in sleep-wake transitions CRF suppression -- reduces corticotropin-releasing factor, potentially lowering stress-related arousal that prevents sleep onset Neuroendocrine modulation -- affects the release of LH, GH, and ACTH at the hypothalamic level The fundamental distinction is that DSIP's mechanism remains undefined after more than 45 years of research
