Whereas specialists weigh the advantages and dangers of melatonin use and the place it’s most secure to attempt, Rishi says the hormone does have a task in medication.
Melatonin will in all probability should be regulated by the FDA as a drugs – particularly for youngsters – Rishi factors out. And what place, if any, it’ll have for managing power insomnia is “an enormous query mark.”
