Melatonin

It is a natural hormone that is secreted by your body’s pineal gland. It helps to maintain your “biological clock,” also referred as the wake-sleep cycle or the circadian clock, an internal 24-hour “clock” that plays an important role in establishing when we wake up and when we fall asleep.

Uses

According to research, melatonin supplements may help sufferers with low melatonin levels (especially people with schizophrenia and people 65 years or older) and people with disrupted circadian rhythms (such as – individuals who work the night shift or people with jet lag) to sleep better.

In the present day, 1 in 3 American adults is not getting sufficient sleep on a regular basis, according to the CDC.

In addition to improving sleep quality, this supplement is known to have an essential role within the immune system as well it has a potent anti-inflammatory action.

Bottom Line – ZzzQuil vs Melatonin

ZzzQuil (active ingredient – diphenhydramine) is a medication that is used to treat motion sickness, to induce sleep, and to treat allergy symptoms. The main and only active ingredient in this medication is also the main ingredient in almost every other over-the-counter sleep medication, and even nighttime pain relievers.

Melatonin is an over-the-counter dietary supplement that may help sufferers with low melatonin levels and people with disrupted circadian rhythms to sleep better.

One review of 15 studies involving 284 subjects concluded that people who took melatonin supplements before bed fell asleep 3.9 minutes faster on average and slept 13 minutes longer.

Regarding ZzzQuil, a study that was presented during an annual meeting of the American Academy of Sleep Medicine and the Sleep Research Society in 2016, showed that OTC sleep medicines help people suffering from occasional sleep difficulties fall asleep in less than twenty minutes and improve their reported quality of sleep.

Basically, ZzzQuil may put you to sleep faster than melatonin, but at the end of the day, is it the best choice?

Most doctors don’t recommend ZzzQuil for sleep difficulties due to the fact that so many people build a tolerance to diphenhydramine. In addition, it doesn’t really fix the underlying problem…it just masks the problem.
