Oh Good! Melatonin Gummies make a delicious addition to your nightly routine. These natural berry-flavored vegan gummies provide 10 mg of melatonin per serving and, true to their name, are oh so good. Melatonin is a hormone naturally produced by the body in response to darkness to help prepare you for rest. As adults get older, melatonin levels may begin to decline, and taking these delicious gummies is a convenient option when it’s time to catch some of those sweet Zzzs.
