Can’t sleep? Consumer Reports looks at the pros, cons of sleep supplements

You toss, you turn, you keep fluffing that pillow, but as hard as you try, you just can’t fall asleep.

“If you’re consistently losing sleep, studies have shown that it can wreak havoc on your body -- and increase your risks for anxiety and depression,” said Consumer Reports Health Editor Kevin Loria.

According to a recent Consumer Reports survey, only 42% of us would describe our sleep as good or very good -- which is why about 30% of people say they have taken supplements to sleep better.

Unlike sleep medications, which are prescribed by a doctor, sleep supplements can be found over the counter. Store shelves are stocked with pills claiming to help you sleep, like melatonin, which is a naturally produced hormone that regulates our sleep-wake cycle and helps control when you’re sleepy and when you feel awake.

Evidence does suggest that taking melatonin can help you doze off about 7 minutes faster, on average.

“Research shows it may be useful for people with jet lag or certain sleep disorders but be sure not to overdo it - you don’t want to interfere with your body’s natural production of melatonin,” Loria said.

Other supplements you may find promoted out there to help you sleep include CBD, which is a compound that is found in both hemp and marijuana, and it doesn’t get you high. Some early research suggests CBD may be a reasonable treatment for insomnia, but a lot more research still needs to be done.

One study suggests that if your vitamin D levels are low, adding it may help you nod off faster and sleep longer.

And if restless leg syndrome keeps you up at night, your doctor might suggest taking iron.

“If you do decide to try a supplement, be sure to look for a trustworthy seal on the bottle from a group like, U.S. Pharmacopeia, or NSF,” Loria explained.

And don’t forget, you can also supplement your sleep supplements -- perhaps with a white noise machine. Consumer Reports’ experts thought the Magicteam Sound Machines White Noise Machine -- starting at about $21.99 -- was the perfect combination of inexpensive and easy to use, with high-quality sound.

Other things you can do to help you sleep are limiting your screen time before bed and avoiding caffeine after lunchtime.
