Melatonin is the most popular sleep supplement in many countries, but quality varies widely. A 2023 study in JAMA found that 22 of 25 melatonin gummy products tested were mislabelled, containing between 74% and 347% of the melatonin listed on the label. That makes choosing a trustworthy, low-dose product important.

Below are popular melatonin options and what each is best for. We have not personally tested these supplements; our picks are based on dose, form and third-party testing information. Talk to your doctor or pharmacist before taking melatonin, especially if you take other medicines.

Quick answer

Choose a low dose (0.3 to 3 mg), a tablet or capsule rather than gummies if accuracy matters, and look for third-party verification such as USP Verified. Take it 1 to 2 hours before bed, use it short term, and remember that melatonin helps most with jet lag and shifted sleep schedules, less with general insomnia.

Who melatonin may help

According to the US National Center for Complementary and Integrative Health (NCCIH), melatonin may help with jet lag, delayed sleep-wake phase (being a “night owl”), and some sleep problems in shift workers. Its benefits for ordinary insomnia are small. For many people, better sleep habits work better in the long run. See our natural sleep aids guide.

How to choose a melatonin supplement

  • Low dose: more is not better. Many experts suggest starting with 0.5 to 3 mg.
  • Third-party testing: look for the USP Verified mark and check that the specific product is listed in the USP registry.
  • Form: tablets and capsules are usually more consistent than gummies.
  • Simple ingredients: avoid blends with many herbs unless your doctor approves.
  • Storage: keep away from children; gummies can look like sweets.
