A good night’s sleep is within reach. Nature Made® Zero Sugar‡ Melatonin Extra Strength 5mg Gummies are fast-acting to help you fall asleep. Best of all, these Melatonin gummies are aspartame free! We sweeten with a sugar alcohol known as maltitol, which has the best GI tolerance among the sugar alcohols[1]. Melatonin is a hormone naturally produced in your brain in response to darkness, but exposure to light at night (like from your cell phone or TV) can affect production. Since Melatonin helps to regulate your body's sleep and wake cycles, occasionally taking supplemental Melatonin one hour before bedtime helps support restful sleep.†
