Essential SLEEP is to be taken 1 hour before bed,and is designed to improve problems with sleep. Essential SLEEP was formulated to help support the neurotransmitters dopamine and serotonin, which have a role with sleep cycles and anxiety. Neurotransmitters are natural chemical messengers in the nervous system that sends signals from one nerve cell across the synapse to another nerve cell or target organ. Serotonin plays a role in sleep, mood, intestinal function, pain control, and inflammation. Dopamine plays a role in cognitive function, memory, learning, and pleasure. In our bodies, dopamine is released as a result of rewarding experiences. Certain nutrients help to balance levels of neurotransmitters by providing co- factors that assist in the body’s ability to manufacture these key chemical messengers.
