We get asked a lot by parents, who have received guidance from their medical provider, about what dose of melatonin they should give to their child or for themselves. We always recommend you consult with your physician but listed below is the recommended dosing.
Melatonin has many uses and is proven to be quite effective at more than just help with sleep. Melatonin is a great option for parents looking for a clinically proven option to help either themselves or their kids get the sleep they need without the risk and negative side effects that drug-based products carry.
The following doses have been studied in scientific research however we always recommend starting with the lowest recommended dose:
