Optimum Melatonin 30 Caps is formulated to offer a convenient nightly sleep support aid for adults experiencing occasional sleeplessness or disruptions in their sleep patterns. Melatonin is a hormone naturally produced by the pineal gland that helps regulate circadian rhythm (the sleep–wake cycle). Supplemental melatonin is commonly used as a short‑term regimen to support healthier, more regular sleep patterns, especially for individuals with irregular schedules, jet lag, or difficulty falling asleep.
