Melatonin CR is a vegetarian formula with a biphasic delivery system that releases melatonin quickly and then steadily. Melatonin is naturally produced in the pineal gland in response to changes in light exposure; it helps promote healthy sleep patterns as well as antioxidant and immune activities. Melatonin CR can support these functions by helping to maintain normal levels of melatonin in the body.* Supplement Facts Serving Size: 1 TabletServings Per Container: 90 Amount Per Serving % Daily Value Vitamin B6 (as pyridoxine HCl) 10 mg 588% Calcium (as dicalcium phosphate dihydrate) 35 mg 3% Melatonin 5 mg ** ** Daily Value not established.
