ENADAlert® (NADH), A NUTRITIONAL SUPPLEMENT, IMPROVED
ASPECTS OF COGNITIVE PERFORMANCE FOLLOWING SLEEP DEPRIVATION
White Plains, N.Y. Researchers in the Sleep-Wake Disorders
Center, New York Weill Cornell Medical Center, tested
the ability of oral stabilized NADH* (ENADAlert) to
improve alertness, mood, and performance on cognitive
(thinking) tasks in 25 healthy middle-aged adults after
one night of total sleep deprivation. In previously
published clinical studies, NADH has been shown to increase
energy and alertness in adults with Chronic Fatigue
Syndrome1 and to reduce the effects of jet lag on cognitive
performance and sleepiness2.
Sleep deprivation is a common problem affecting most
people during adulthood. It impacts otherwise healthy
individuals who cross time zones, work during evening
or nighttime hours, or have infant children, as well
as patients with sleep disorders, certain psychiatric
disorders, and medical conditions such as those that
produce chronic pain. Sleep deprivation can lead to
declines in cognitive performance, impacting the quality
of waking time and, if severe enough, can lead to vehicle
collisions and occupational consequences.
In this double-blind crossover study, subjects performed
significantly better on some measures of cognitive performance
following one night of total sleep deprivation when
they received the NADH supplement compared to placebo.
In particular, overall performance efficiency (number
of correct answers per minute) measured one hour after
consuming 20 mg of sublingual NADH was significantly
higher than after placebo. In a second analysis, math
throughput and visual sequence comparison speed and
throughput were themselves significantly better following
NADH. Self-reported alertness, sleepiness (both self-reported
and objectively quantified), and mood did not differ
when the subjects consumed NADH or placebo. Although
several subjects reported typical effects of total sleep
deprivation, no adverse effects were attributed to NADH.
This study is among the first to rigorously evaluate
a non-prescription substance other than stimulants,
like caffeine, for alleviating the effects of sleep
deprivation. Dr. Margaret Moline, the lead researcher
and Director of the Sleep-Wake Disorders Center at the
Westchester Division of New York-Presbyterian Hospital
in White Plains, states, "NADH is the first non-stimulant,
non-herbal product to show signs of improved cognitive
performance, despite normally reported increased sleepiness
and fatigue following sleep deprivation. These results
suggest that NADH may have an important role to play
in mitigating some of the effects of unavoidable sleep
deprivation."
