NOW Foods Liquid Melatonin delivers 3 mg of melatonin per 1 mL serving in a fast-acting liquid format that allows for sublingual or swallowed administration and easy dose adjustment. The liquid form absorbs faster than capsules or tablets, making it ideal for those who need quicker onset for sleep or jet lag management. The dose can be easily halved or quartered by adjusting the dropper — particularly useful for children or those who find standard doses too strong. Melatonin is the body's primary sleep hormone, signaling the onset of darkness and sleep to the brain's circadian clock. Research supports melatonin for sleep onset difficulty, jet lag adjustment, shift work, and general sleep quality improvement. NOW Foods' liquid melatonin is naturally flavored, free from artificial additives, and manufactured in their GMP-certified facility.
