Calm Day is a dietary supplement that provides nutrients and amino acids to support the neurotransmitters, dopamine and serotonin in the brain for calming mood and a natural sleep cycle. Neurotransmitters are natural messengers in the nervous system that send signals from one nerve cell across a 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. Certain nutrients and amino acids may help to balance levels of neurotransmitters by providing co-factors that assist in the body’s ability to manufacture neurotransmitters.
