According to the Centers for Disease Control and Prevention (CDC), about 1 in 3 Americans don’t get enough sleep. Others may experience poor sleep or insomnia. But melatonin, a widely available supplement, may help with several sleep issues.

Research from 2014 reported that it shows promise in the treatment of insomnia among healthy adults. Some people also use it for jet lag, delayed sleep-wake phase disorder (DSWPD), and anxiety before or after surgery.

Quicksilver Scientific Liposomal Melatonin Spray

Price: $$$

This supplement spray comes in a sleek spray bottle. One pump delivers 1 mg of melatonin, but you can up the dose as needed.

Liposomal refers to the method of delivery. In this case, the melatonin is encased in a small, fat-like particle that allows it to be absorbed more easily. An added benefit of liposomal supplements is that they tend to have fewer side effects.

Quicksilver Scientific is cGMP certified. The company also states that they regularly conduct third-party lab testing on their products.

Price: $$

This 30-pack of individually wrapped honey-lavender lozenges is a favorite at CVS and Walmart. Each lozenge contains a 1-mg dose of melatonin. Customers say that although they aren’t the most potent, they taste great and feel soothing on the throat.

Luden’s is a trusted cough drop manufacturer. They third-party test all of their products.

Price: $

Liquid melatonin offers the benefit of fast absorption. This non-GMO, vegan formula is free of most gluten, dairy, and eggs. Customers describe the flavor as mild and citrusy but sweet.

One of the downsides of this product is that it doesn’t come with a dropper to measure the liquid. If you have a 1/4 teaspoon measuring spoon, you can use it to measure out the 0.9 milliliter (mL) dose.

NOW is a cGMP-certified company.

Luminite Sleep Support Capsules

Price: $$$

What sets this product apart is its unique combination of ingredients. Each capsule contains 4 mg of melatonin, plus chamomile, passionflower, and GABA.

It’s one of the few formulas to also include L-tryptophan, an amino acid that has been linked to better sleep quality. Other calm-inducing ingredients include hops and skullcap powder.

Luminite is manufactured in accordance with cGMPs.

Melatonin is a hormone that is naturally produced in your brain. It helps to control your day-night rhythm, also known as your circadian rhythm, by making you feel sleepy when it’s dark. It likely has other functions as well.

Melatonin supplements are usually synthetic, but they can also be extracted from animals or other organisms. When you take melatonin supplements, they work the same way as the naturally occurring version of the hormone.

Melatonin is considered a dietary supplement by the FDA. Unlike prescription and over-the-counter (OTC) drugs, dietary supplements aren’t subject to approval by the FDA.

Still, supplement manufacturers must provide accurate safety information about their products. They may be penalized for making false claims.

That doesn’t mean all supplement brands are trustworthy. When shopping, you might want to consider buying from a big-chain drugstore where you can talk to a pharmacist about the product. Well-known chains may be less likely to stock fraudulent products.

In addition to factors such as price, flavor, route of administration, and dose, you’ll want to assess the product label and packaging. Look for the following:

  • Does the label make claims that sound too good to be true? For instance, does it claim to cure insomnia? Exaggerated claims can signal a scam.
  • Where is the product made? Opt for products manufactured in the United States.
  • Has the company or product received an FDA warning letter or recall alert? If so, you’ll want to steer clear of it.
  • Are the ingredients listed? Does the supplement contain ingredients that are forbidden by the FDA?
  • Does the product have a USP verification mark or NSF certification? This signals that the ingredients in the product correspond to those on the label.

Not all melatonin supplements are the same. Read and follow the label carefully. If you’re not sure what to do, ask a pharmacist for instructions on how to take melatonin.

You can take between 0.5 and 10 mg of melatonin per day. It’s best to start with a lower dose and work your way up to a higher dose if needed.

Take it about 30 minutes before you go to bed.

Little is known about the long-term effects of taking melatonin. If you find you have to take melatonin most nights for more than 1 month, you should talk to your doctor to rule out any underlying sleep disorders.

According to research from 2016, using melatonin in the short term is safe for most people. The research determined that only mild side effects have been reported. These include:

  • headaches
  • dizziness
  • nausea
  • drowsiness

There’s still very little research on melatonin safety among children and people who are pregnant or breastfeeding. Since melatonin is a hormone, it could interfere with other hormonal functions, such as puberty or lactation.

In addition, the American Academy of Sleep Medicine discourages melatonin use among people with dementia.

Melatonin can interact with other drugs and supplements. If you’re taking OTC or prescription medication or other supplements, it’s especially important to talk with your doctor before taking it.

Melatonin is a hormone that makes you feel sleepy when it’s dark outside. Taking a melatonin supplement may improve sleep quality.

There are hundreds of melatonin supplements on the market, including capsules, tablets, gummies, liquids, and sprays. It’s important to evaluate the manufacturer’s claims critically when shopping for a supplement.

Always ask a doctor or pharmacist if you’re not sure about a product. Consult with your doctor before trying any new supplement.
