L-carnitine is an amino acid derivative that plays an important role in the transport of fatty acids to the mitochondria and increases energy production required by sperms for normal functioning
83 Another randomized controlled trial in 100 adults over 50 years of age with poor sleep found 320 mg magnesium (as magnesium citrate) per day for seven weeks improved sleep quality scores

A panel of experts recently compiled a list of recommendations and considerations specifically for shift workers to optimize the quality of their sleep 337 : Prioritize sleep (consider rescheduling non-essential tasks to not cut into sleep time) Aim for seven to nine hours of sleep per 24 hours Develop a sleep schedule Develop a bedtime routine Plan your transition to days off Use napping, in 15- to 20-minute bouts, as a helpful tool When planning sleep time, remember that sleep inertia (the groggy time between ending sleep and being fully awake) impairs performance and can raise the risk of accidents Create a comfortable sleep environment Use your bed only for sleep and intimacy Consider whether the amount of light in the sleep environment is affecting sleep Consider whether caffeine intake is affecting sleep Consider whether nicotine consumption is affecting sleep Consider whether alcohol intake is affecting sleep Be mindful of medications that may interfere with sleep Consider whether nighttime hunger or fullness is affecting sleep Consider whether the timing of fluid intake is affecting sleep Engage in regular exercise Develop strategies for sleep problems Breathe Well During Sleep Breathing through the nose is important for warming, humidifying, and filtering inspired air, and the proportion of breathing that occurs through the nose (as opposed to the mouth) normally increases during sleep
