NATURAL FACTORS - Tranquil Sleep - 120 Chewable(s) - NPN: 80016397 -- Our health depends in no small measure on the amount and quality of sleep we get. One in three Canadian adults experiences some degree of insomnia. Many try pharmaceutical sleeping pills, but these may have addiction potential and unpleasant side effects. Tranquil Sleep is a safe, advanced formula, in delicious chewable tablets, that can help you fall asleep faster, stay asleep, sleep more soundly and wake up refreshed. Tranquil Sleep contains a synergistic combination of Suntheanine (the same patented form of L-Theanine used in Mental Calmness) to calm the mind and promote restful sleep, and two other powerful sleep enhancers: 5-HTP, an amino acid that helps stimulate important brain chemicals related to sleep; and melatonin, a hormone that helps induce sleep, especially in people with low melatonin levels.
