Every Melatonin deal here is ranked by cost per dose— what you actually pay per serving, not the sticker price. Forms and absorption differ, so the cheapest bottle isn’t always the cheapest dose.
Right now the best value across our full Melatonin catalog is at $0.04 per serving.
Melatonin is a hormone the brain produces in response to darkness, and supplemental forms have been studied for several sleep-related and other conditions. Research suggests melatonin supplements may help with jet lag, and studies in children with sleep disorders found it better than placebo for time to fall asleep and total sleep; there is also strong evidence it is better than placebo at reducing anxiety before surgery. For chronic insomnia there is not enough strong evidence on its effectiveness or safety, shift-work studies were generally small or inconclusive, cancer studies have been small with mixed results, and for delayed sleep-wake phase disorder it is uncertain whether the benefits outweigh the possible harms — per the NIH National Center for Complementary and Integrative Health; not medical advice.
Melatonin supplements can be made from animals or microorganisms but are most often made synthetically; product quality is a concern, as a 2017 study of 31 supplements found the melatonin amount often did not match the label and 26 percent contained serotonin, and a 2023 study found 22 of 25 over-the-counter melatonin gummy products were inaccurately labeled — per the NIH National Center for Complementary and Integrative Health.
Short-term use of melatonin supplements appears to be safe for most people, but information on long-term safety is lacking; reported side effects in adults include headache, dizziness, nausea, and sleepiness, and in children drowsiness, increased bedwetting or evening urination, headache, dizziness, and agitation. There is a lack of research on safety during pregnancy or breastfeeding, and experts recommend against melatonin use by people with dementia — per the NIH National Center for Complementary and Integrative Health.
People taking medicine should consult their health care providers before using melatonin; in particular, people with epilepsy and those taking blood-thinner medications need to be under medical supervision when taking melatonin supplements. Cancer patients should talk with their health care providers to make sure all aspects of their care work together — per the NIH National Center for Complementary and Integrative Health.
