Summary of Sleep

Primary Information, Benefits, Effects, and Important Facts

Supplements tha affect sleep may act through altering the time it takes to fall asleep (sleep onset latency), the duration of continuous sleep (sleep disturbances), and the restfulness of sleep (sleep quality).

Supplements for these purposes may directly initiate sleepiness like melatonin, have an affect on stress and anxiety like valeriana officinalis, or make sleep deeper and more restful like glycine.

Frequently Asked Questions about Sleep

Can supplemental vitamin D improve sleep?
Does ZMA cause weird dreams?
It is possible that ZMA can cause weird dreams, and the anecdotes support this; however, since this has not been directly investigated the best 'proof' that can be given is weak.
Ten tips for better sleep
To feel and perform your best, you don’t just need enough sleep, you need enough quality sleep. We break down what you can do — and what you should avoid — to sleep well and wake up refreshed.
How important is sleep?
Sleep is incredibly important, and can be considered crucial alongside diet and exercise. Proper sleep habits help sustain many biological processes, and bad sleep can cause these processes to be suboptimal or even malfunction.
