Dog melatonin is a chewable tablet with a slightly sweet taste. Supplementing with melatonin can be highly beneficial, as melatonin is a well-known antioxidant helpful in regulating hormones and promotes relaxation, calm, and comfort. Melatonin plays an essential role in regulating the sleep-wake cycle in humans, dogs, and other animals. The body naturally produces melatonin in the pineal system. In healthy animals, peak production of melatonin naturally occurs after sunset. Melatonin signals to the body both time of day and season (length of night). However, natural production decreases as we and our pets age. Melatonin for dogs is reported to be an immune system booster and inhibits two enzymes needed in the production of Cortisol, thereby effectively reducing excess Cortisol levels. RECOMMENDED DOSAGE AND DIRECTIONS Veterinarians recommend giving dogs under 30lbs 3mg melatonin (1 tablet) every 12 hours and dogs over 30lbs 6mg melatonin (2 tablets) every 12 hours.
