If you’ve already cleaned up your sleep routine and are looking to further support your sleep with a non-melatonin supplement, there are a few key things to look out for.
For starters, look for ingredients that have been studied in humans, backed by sleep-relevant science, and dosed properly. Fillers like binders; preservatives; artificial colors, flavors, or sweeteners; as well as allergens like gluten, eggs, dairy, or soy are best avoided and often unnecessary.
Be wary of any claims that a supplement can treat sleep disorders. Not only do dietary supplement regulations forbid that, as Harris and Kennaway both note, but those with sleep issues that are getting in the way of their lives will want to see a doctor who can set them up with a regimen that may include lifestyle adjustments, cognitive behavioral therapy, other remedies, or a combination of these strategies.
