Tag: 5mg melatonin

In 2018, Americans were taking more than double the amount of melatonin they did a decade earlier, with many using doses of 5mg or higher [1.4.1, 1.7.1]. While common, it's important to ask: what are the side effects of melatonin 5mg for sleep?

A study found that the use of melatonin supplements among U.S. adults increased more than fivefold between 1999 and 2018. This raises the common question: is 5mg of melatonin too little, too much, or just right for achieving better sleep?
