NADream: Effects of Nicotinamide Adenine Dinucleotide Supplementation on Sleep Quality in Healthy Individuals

The purpose of this study is to evalue the effects of nicotinamide adenine dinucleotide (NAD) supplementation (nicotinamide riboside (NR) form) on sleep in healthy adults compared to a placebo. NAD is important for brain health and energy balance and a proposed explanation for its effect on sleep is that NAD supplementation restores the neurophysiological capacity of the brain to 'rest' during sleep. If this is the case, we expect the administration to result in improvements in sleep quality (and most likely sleep quantity) compared to placebo. Participants will receive either NAD supplementation or a placebo and their sleep will be measured to detect any differences between the two groups.
