Sleep plays a huge role in your physical health and well-being. Chronic sleep deprivation can increase your risk for heart disease, diabetes, and stroke. Inadequate sleep on a short-term basis can heighten hunger hormones and affect your athletic performance, decreasing motivation to get to the gym and leaving you feeling exhausted before you even start your workout.

Melatonin, a hormone naturally made by the body, works with your circadian rhythm to prepare for sleep. While research varies, some studies suggest that melatonin supplements may help you fall asleep, stay asleep, and even improve the quality of your sleep. The popular over-the-counter sleep aid is available in many forms, including capsules, spray, gummies, liquid, and tablets.

Melatonin may interact with certain medications, such as those for blood clotting, seizures, birth control, high blood pressure, diabetes and immunosuppressants. 

Always speak with a healthcare professional before adding a supplement to your routine to ensure that the supplement is appropriate for your individual needs, and to find out what dosage to take.

Here, our picks for the best melatonin supplements to help you get the sleep you need.

If you don't like swallowing pills and aren't a fan of gummy supplements, a lozenge is a good alternative. Source Naturals offers a quick-dissolving, orange-flavored lozenge that contains 1 milligram of melatonin. Simply place the lozenge in your mouth at bedtime, and wait for it to dissolve.

The lozenges are suitable for vegetarians and are free of yeast, dairy, egg, gluten, soy, and wheat. They do not contain any sugar, however, they are sweetened with sorbitol and mannitol, two sugar alcohols that may cause gastric distress in some individuals.

Unlike other sleep aids, melatonin supplements tend to be non-habit forming. Although the level of supplementation can affect sleep time or sleep latency, the effect of melatonin supplementation on sleep quality is the same no matter the duration of supplementation or the dosage.

What to Look for in a Melatonin Supplement


Melatonin comes in a variety of doses ranging from 0.2 to 10 milligrams. There is not one recommended dose, and lower doses often work as well as higher doses. Speak with your physician to figure out if melatonin is appropriate for your individual needs, and if so, the proper dosage.


Melatonin supplements come in a variety of types, including capsules, tablets, sprays, gummies, and lozenges. If you don't like swallowing pills, gummies, sprays, or lozenges may be a good option for you. However, if you prefer to avoid added sugar or sugar substitutes in your supplements, capsules or tablets are usually free of sweeteners.


Always double-check the ingredient list to see exactly what is in your melatonin supplement. Some products contain additional components, such as herbs or complementary vitamins. Additionally, some supplements contain soy, gluten, or other common allergens.

Frequently Asked Questions

  • How long does a melatonin supplement last?

    Many factors affect how long melatonin lasts in the body, including dosing and specific sleep issues. How your body responds to and processes melatonin is influenced by age, overall health, body composition, and caffeine intake.

    The half-life of a medication is what determines how quickly it is released into the bloodstream and how long it takes the body to metabolize half the dose. Depending on the formulation, the half-life of melatonin is one to two hours. A typical over-the-counter dose is 0.1 to 10 milligrams and lasts anywhere from four to 10 hours. 

  • Can melatonin supplementation be habit-forming?

    Unlike sleep medications, melatonin is not addictive and has low risk of side effects. It also doesn’t lead to withdrawal or habituation (needing higher doses with increased use).

    There isn't enough research to determine if melatonin is safe to use in the long term, but is known to be safe for short-term help with sleep. As with any supplement, always talk to your doctor to ensure it is safe for you.

  • When should you take melatonin supplements?

    You should take a melatonin supplement 30 to 60 minutes before you would like to fall asleep. Melatonin usually peaks within 1 hour of taking it, so you need to allow enough time to let it peak before you go to sleep.

    It is also important to take melatonin around your ideal bedtime and not after, as this can change your sleep-wake cycle, causing you to fall asleep later than you would like and feel very tired during the day.

    Melatonin affects everyone differently, so there may be a bit of trial and error to find the dose and timing that works best for your body and specific sleep pattern. 

  • Does melatonin interact with other medications?

    Melatonin can interact with various medications, so check with your doctor if you have any health conditions. Certain antidepressants may increase melatonin absorption, causing excessive drowsiness and fatigue. Melatonin interacts with anticoagulant drugs and can make them less effective by slowing blood clotting.

    If you have diabetes, it is important to monitor your blood sugar closely while taking melatonin as it increases blood sugar, decreasing the effectiveness of your diabetes medications. 

  • How are melatonin supplements made?

    Melatonin supplements are typically made synthetically, but sometimes they are made from animals or microorganisms. If they are made from animals, the hormone is taken from the pineal gland, where it is produced in humans as well.
    Melatonin supplements are found in pill, liquid, and chewable forms and the synthetic type is usually recommended by doctors. 

What Experts Say

"Melatonin is naturally made in the brain and is critical for adequate sleep. Melatonin and cortisol (the fight-or-flight hormone) oppose each other, so if someone is super stressed (high cortisol), they will likely have lower melatonin levels. A melatonin supplement may help to restore melatonin levels and promote adequate sleep. Adequate sleep improves control of other hormones, such as hunger and satiety hormones, which can make maintaining your weight more manageable."
